Thread IP initialization
by jason philip 15 Jan '11

15 Jan '11

How do initialize the IP or SP for thread or determine it location? In the "ThreadControl" system call (which used to create threads) it requires a IP and a SP, so where you get these values from? Are they implicitly determined by the kernel? I've briefly read pingpong source file but the calls made in the source do not seem to provide these values. And also how do I load program in order to execute it? I know this probably sounds like an easy question but I just started experimenting with l4 and I just getting to know things.

I'd be interested in taking a look at this snapshot if you are willing to share it. I'm doing some investigation work into how to put together an execution environment like your proof of concept.

Explanation of ARM TrustZone Support?
by Wesley Miaw 13 Jan '11

13 Jan '11

Hi, I was wondering if someone could point me at documentation, or describe in a reply, how L4 Fiasco + L4Re makes use of the ARM TrustZone hardware? I see that support for TrustZone is listed listed as one of the features of Fiasco, but haven't been able to figure out exactly what that means. If built for an ARM chip with TrustZone support, does L4 automatically set up a TrustZone execution environment for each L4 server? Or do I need to tell it somewhere to put each server into its own environment? Are the hardware calls automatically made when switching between servers? How does use of TrustZone influence message passing between servers? I'm afraid all I've found in the source appears to be some code in the hardware porting layer that is a relative mystery to me. Thanks, -- Wesley Miaw wesley(a)wesman.net

Hi Adam, I don't know what caused the problem, but I have figured out how to work around it. I was compiling with the "Sourcery G++ Lite 2010.09-50" build. Your README indicates "Sourcery G++ Lite 2009q3-67" is known to work. I downgraded to that version and now L4linux starts up without any errors. Thanks, -- Wesley Miaw wesley(a)wesman.net

Problems booting Pistachio
by Ashford Nichols 26 Dec '10

26 Dec '10

I recently built the microkernel and tried to boot it using "qemu" but it doesn't work. qemu just seems to not even seem to recognize the image as a bootable image. I followed the instructions given on the site and everything worked, right up to the point where it doesn't boot. I must say though that I did slightly tweak the steps given on the site to create the image file since the original ones didn't work for me. I am really new to qemu so I don't have the slightest clue as to why this isn't working. If anyone experienced this problem or at least know how to resolve this please help me. The step I followed in order to create the image follows: dd if=/dev/zero of=l4-image.img bs=512 count=8640mke2fs l4-image.imgmkdir /media/mount_pointmount -o loop l4-image.img /media/mount_pointmkdir /media/mount_point/bootmkdir /media/mount_point/boot/grubcp -aR grub_stages/* /media/mount_point/boot/grubcp -aR modules/* /media/mount_pointumount /media/mount_point

schedule system call
by Ashford Nichols 20 Dec '10

20 Dec '10

In version 2 of the interface under the schedule system call, it says that the call can be used be schedulers. However, in the next sentence it goes on to say that the calling thread must reside in the same address space as the scheduler. Also, it goes on to say that an error code will be set if the calling thread is not the scheduler. So is the "schedule" system call made by the scheduler or by a thread that simply resides in the same address space as the scheduler?

Several questions
by Nuno Santos 10 Dec '10

10 Dec '10

Hi I've managed to build and run Fiasco with one instance of L4Linux. At this point I have several questions: - I believe that an application running in l4linux can communicate with an application sitting on fiasco. Is there a simple example I could look at? - As a follow up, how can we allow multiple l4linux instances to communicate using IPC? This post from 2005 [1] has done precisely what I need. Would it be possible to share that code? - I'd like to use and deploy a tpm driver directly on top of L4 (not directly accessible to l4linux). Is it possible to obtain that driver? How to set it up? This post [2] mentions the stpm package, but I couldn't find it in the l4re snapshot. - Is it possible to plug a TPM emulator to work directly on fiasco? It's mostly for experimentation and testing on machines without a physical TPM. - I believe that it's possible to boot fiasco with a trusted bootloader. [2] mentions oslo, but again I couldn't find the code in the snapshot. Do you know where can I find it? Do you know if trusted grub can be used as a viable alternative? I've looked extensively for online information, but I confess I'm a bit overwhelmed. Your guidance here would be fantastic. I really appreciate your help. Thanks! --Nuno [1] http://www.mail-archive.com/l4-hackers@os.inf.tu-dresden.de/msg01709.html [2] http://www.mail-archive.com/l4-hackers@os.inf.tu-dresden.de/msg03861.html

Stringitem
by BERTRAND Joel 04 Dec '10

04 Dec '10

Hello, I think I have misunderstood StringItem IPC but I don't know where is my mistake. My roottask spawns a thread that sends a stringitem to roottask. I have checked with debugger that this stringitem contains my string : si = L4_StringItem(str.length_trim, (void *) str.c); L4_Clear(&msg); L4_Append(&msg, si); L4_Set_Label(&msg, CALL$PRINT); L4_Load(&msg); L4_Call(L4_Pager()); str is a struct vms$string : struct vms$string { vms$pointer length; vms$pointer length_trim; unsigned char *c; }; My roottask receives this IPC in following function: void sys$loop() { int running; L4_ThreadId_t partner; L4_MsgBuffer_t buffer; L4_MsgTag_t tag; L4_Msg_t msg; running = 1; L4_Accept(L4_MapGrantItems(L4_CompleteAddressSpace) + L4_StringItemsAcceptor); tag = L4_Wait(&partner); while(running) { L4_Clear(&msg); L4_Store(tag, &msg); if ((tag.raw & L4_REQUEST_MASK) == L4_PAGEFAULT) { sys$pagefault(partner, L4_Get(&msg, 0), L4_Get(&msg, 1), tag.raw); } else { switch(L4_Label(tag)) { case CALL$PRINT: notice("Here!\n"); break; default: PANIC(1, notice(IPC_F_UNKNOWN "unknown IPC from $%lX " "with label $%lX\n", L4_ThreadNo(partner), L4_Label(tag))); } } tag = L4_ReplyWait(partner, &partner); } return; } When system boots, I can intercept on serial line: ... %SYS-F-PAGEFLT, pagefault request from $3C at $0000000000800110 %SYS-F-PAGEFLT, pagefault request from $3C at $000000000010FFF8 %SYS-F-PAGEFLT, pagefault request from $3C at $00000000008015C0 %SYS-F-PAGEFLT, pagefault request from $3C at $0000000000801C10 Here! %IPC-F-UNKNOWN, unknown IPC from $0 with label $0 Panic at sys$loop, sys/sys_loop.c line 73 Have a nice day ! Backtrace: <00> [$000000000104F5B8] -> $0000000001004ED5 (sys$loop) <01> [$000000000104F838] -> $0000000001005813 (main) Pagefault messages are written by sys$pagefault() subroutine. As sys$loop() function writes 'Here!', it receives an IPC with CALL$PRINT label. First question: I don't know how read this stringitem. I have tried with msgbuff without any result. I suppose I have misunderstood how StringItem IPC works. Second question: I don't understand last line: "%IPC-F-UNKNOWN, unknown IPC from $0 with label $0". I suppose this error comes from a bad stringitem IPC. I haven't found any stringitem IPC example. Help is welcome. Regards, JB

Some questions about pager
by BERTRAND Joel 29 Nov '10

29 Nov '10

Hello, It's my first post on this mailing list. A long time ago, I have started to write a VMS-clone (http://www.freevms.net). This opensourced project was sleeping for a long time because monolithic kernel isn't good enough to write a clone of this system. Thus, I have restarted this project with a L4 microkernel (exactly pistachio L4/X2). Now, I have written a roottask that tries to launch VMS$INIT, first thread required to boot all system. I have reuse some works done for iguana project (and fixed some bugs). When VMS$INIT is started, this thread sends two IPC to its pager : vms$pagefault(addr:1001730, s:8000) [priv=4] -> default addresse is $1001730 (start address of VMS$INIT thread) ... vms$pagefault(addr:47fe8, s:2000) [priv=4] I'm not sure that I have understand how should work a pager. I have uploaded my pager here : http://www.freevms.net/trac/browser/sources/freevms/vm/vm_pagefault.c All sources are available with : git clone git://rayleigh.systella.fr/FreeVMS.git and I have uploaded a disk image that runs with qemu (with a x86/64) : http://www.systella.fr/~bertrand/freevms.img.bz2 My pager tries to find a physical free page to map virtual memory. I think that memory is correctly mapped and I don't understand why pager receives other request with same virtual address. I suppose I have done a mistake. Any idea ? Thanks in advance for all explanations, JB

Hi , I am running into a few issues while trying to run the l4linux image on the realview board. when i execute the command on the boot monitor prompt M> run l4linux.elf i get some garbled output on the screen and then system goes unresponsive ( a blinking cursor) . I had assumed that i will get some kind of a shell prompt after booting.Is this assumption correct? I have the minicom configured correctly ( used the values suggested on the realview user guide) ,so i think the error is not on that side. Has anyone run into this issue before. I will appreciate any pointers on resolving this issue.

Booting Fiasco with U-Boot (or: what is 0x002000000?)
by Thomas DuBuisson 03 Nov '10

03 Nov '10

All, Thanks for the previous help with building Fiasco/L4Re. Now that its built I have given a couple stabs at booting it on my beagleboard like device (I'll document all this in a blog and or wiki when/if I finish). Unfortunately I can't seem to get any sign of life on the screen (perhaps I should solder up a serial line for debugging purposes). What I've done: 1) Cross compiled L4Re and Fiasco for the beagleboard. 2) Copied l4re, lua, moe, fiasco, and created hello.lua to the SDs first partition (the fat boot partition). 3) Rebuilt/copied over u-boot.bin using: #define CONFIG_EXTRA_ENV_SETTINGS \ "bootargs=tbr=x console=tty1 omapfb.mode=dvi:1024x600MR-16@60 omapfb.vrfb=1 omapfb.vram=0:8M,1:4M,2:8M root=/dev/mmcblk0p2 rootdelay=1 rootfstype=ext3\0" #define CONFIG_BOOTCOMMAND \ "mmc init; fatload mmc 0 0x02000000 fiasco; bootm 0x02000000" Though I have tried different addresses including what I think is a typo on the "Getting Started" page of 0x002000000. So some questions are: 1) I'm pretty sure the bootargs need changed. For example, does u-boot need to load ned, moe, and hello? Where should they be loaded? Any other comments on what fiasco expects the bootloader to do? (this is different than what the wiki provides of "how to do those unspecified things using GRUB") 2) To what address should I load fiasco? I assume it matters. 3) If these questions are already answered somewhere then I'd be more than happy with a link. Cheers, Thomas

I use the default configuration file. The results of the command "make O=path/to/builddir" failed because of an undefined reference to _stack_chk_fail_local. After some research I understand this "undefined reference" is add by gcc which is in version 4.4.4 on my fedora 13 OS.

Fiasco / L4Re compilation issues
by Thomas DuBuisson 01 Nov '10

01 Nov '10

All, I've never had success with Fiasco but decided to give it another go so I could run some benchmarks. In short, I had one success and two failures. Any help would be appreciated. 1) I can build Fiasco for x86 on the host (32 bit x86 system). Yay 2) Can't build Fiasco for ARM on an x86 host due to... an old arm-linux-gcc version? 3) Can't build L4Re due to linker error. 1) Successful build of Fiasco x86 This and other builds are using a recent pull from the repo [1] on a Fedora based 32bit x86 system running gcc 4.4.4 on Linux 2.6.34. 2) Failure to build Fiasco ARM This early failure seems to be a simple problem with gcc changing the arguments - can anyone tell me the version of the "official" arm compiler in use? I'm running arm-linux-gcc 3.4.4. ------------ make[1]: Entering directory `/home/tommd/dev/L4/L4Re/build_arm' ... Generating version information ... Making kip.o cc1plus: error: invalid option `abi=apcs-gnu' make[1]: *** [kip.o] Error 1 ------------- 3) Failure to build L4Re due to linker error The symbol "__stack_chk_fail_local" is missing when building "libl4util.so" (see below). A quick objdump/grep doesn't show this symbol in any object file in the build directory - is the build system slightly broken?

How to compile DDekit in l4re-snapshot-2010080920?
by 方明伟 25 Oct '10

25 Oct '10

Hi : Everyone! I am a new one to use fiasco.OC. Now, I am compiling L4Linux for X86 and arm. But I didn't know how to configure the DDekit. In "l4/pkg/dde/Makefile", three senteces are being commented. "# $(VERBOSE)PWD=$(PWD)/linux26/include $(MAKE) -C linux26/include # $(VERBOSE)PWD=$(PWD)/linux26/contrib/include $(MAKE) -C linux26/contrib/include" "# $(VERBOSE)PWD=$(PWD)/linux26/lib $(MAKE) -C linux26/lib" Does that mean I can't use the DDekit now? So I wondered can DDekit be used in L4Re? If yes, how can I configure and compile the dde in /l4/pkg?

L4Re multiple Linux instances communication
by Michael Weiß 27 Sep '10

27 Sep '10

Hi, I'm trying to establish a communication between several L4Linux instances on fiasco.oc kernel with L4Re on the beagle board, preferable through a virtual network. I found out that the outdated L4env provided a virtual netwok switch, ORe and the l4ore driver in L4Linux for that purpose. Is there something similar available for L4Re and how can I setup a connection between two L4Linux instances? Thanks, Michael

The xM uses DM3730 main chip, which is supposedly "compatible with OMAP-3 architecture." Both chips built around cortex-A8 core, so hopefully all will be well. Brett.

Debugging applications on Fiasco.OC. and questions about L4re
by Pablo Montesinos 01 Sep '10

01 Sep '10

(sorry if it's a duplicate, I sent the previous one from an account outside the mailing list and I did not know whether it would go through) Hi, I need to debug an application that I've ported to Fiasco.OC and I was wondering what is the preferred way to do it. (The application works fine in Linux, but there must be something wrong with the libraries I ported). Jdb seems not very friendly if all you want to do is debugging an application. My second question is about L4re. So far, all the applications running on my Fiasco.OC are console-based. However, I would like to run more complex apps that might require a graphical environment. I noticed that, with L4env, it was possible to have it. Is it possible to do it with L4re? Any plans to add it in the near future. I would use Genode, but I've been told at the Genode list that Fiasco.OC is not supported by Genode. Is there an alternative to Genode on L4re? Thanks, Pablo

Fiasco.OC hangs in Intel Core 2 duo
by Karthik Vadambacheri Manian 29 Aug '10

29 Aug '10

Hi all, I compiled the new Fiasco.OC microkernel and L4RE in my Core 2 Duo PC with gcc 4.4.3. While configuring the Fiasco.OC microkernel I selected PC architecture as AMD64 and CPU type as Intel Core 2. But while configuring L4RE when I selected the PC architecture as AMD64 there is no option for CPU type as Intel Core 2. Hence I selected PC type as K8 which is one of the options. I created the cd image using *make grub2iso E=hello. *But when I run the virtual machine in qemu-system-x86_64 it hangs. I have tested the same with different PC type as K10/Barcelona, opteron, but got the same result.

Using L4Linux on Fiasco.OC - How?

Hi, I just started porting some Projects running on L4Linux on the "old" Fiasco to Fiasco.OC with the current L4Linux version. Starting with the "hello" example of the documentation was no problem, but I could not find out how things have to be configured when using L4Linux. Which dependencies must be regarded to make it run properly? Is there any documentation I could use, or can anyone publish some example documentation and configuration to run L4Linux on Fiasco.OC?

[ANNOUNCE] NOVA Microhypervisor 0.2 prerelease
by Udo A. Steinberg 06 Aug '10

06 Aug '10

Hi, The NOVA project is happy to announce that there is a new prerelease of the NOVA microhypervisor available for download at http://www.hypervisor.org/ or http://os.inf.tu-dresden.de/~us15/nova/ under the terms of the GNU General Public License version 2. NOVA is based on a modern microhypervisor written in C++ and assembler. The current implementation supports x86-32 SMP platforms with hardware virtualization features such as Intel VT-x/VT-d or AMD-V, and facilitates running multiple unmodified guest operating systems in virtual machines with near-native performance. On machines without VT-x or AMD-V, the functionality is reduced to that of a microkernel. The most prominent new feature is support for I/O virtualization and direct assignment of host devices to guest VMs using the IOMMU. For a list of other changes, please see the change log included with the source code. Cheers, - Udo

L4Re Makefile bug?
by Michael Kirkpatrick 03 Aug '10

03 Aug '10

I've downloaded the l4re-core-2010070715.tar.bz2 archive, and I've tried to build the project. I have no problem compiling the Fiasco.OC kernel, but the L4Re core build seems to be entering an infinite loop. After running for a few seconds, I get the following lines repeated forever: All checked ok. scripts/kconfig/conf -s [l4dir]/mk/Kconfig scripts/kconfig/conf -s [l4dir]/mk/Kconfig make[11]: Nothing to be done for `all'. I also noticed that I get this same infinite loop if I do make config (after the menu exits) or make oldconfig. Something about the post-config clean-up seems to be continuously forking new processes and looping. The comment at line 179 of the [l4dir]/Makefile indicates that make is called again for postprocessing, but I don't know make well enough to debug this problem. Any ideas what's causing the problem?

l4vfs and stdin/stdout handles
by Valery V. Sedletski 02 Jul '10

02 Jul '10

Hi all. I am trying to make a test using l4vfs libc backends so the three predefined file descriptors 0, 1, 2 work for stdin, stdout and stderr correspondingly. It appears that these file descriptors are already predefined for some purpose: when I am trying to open files like this: // open initial file descriptors // stdin fd = open("/vc/vc0", O_RDONLY); LOG("stdin: fd=%d, errno=%d", fd, errno); // strout fd = open("/vc/vc0", O_WRONLY); LOG("stdout: fd=%d, errno=%d", fd, errno); // stderr fd = open("/vc/vc0", O_WRONLY); LOG("stderr: fd=%d, errno=%d", fd, errno); -- like in term_con_test example for term_con server, the 3, 4, 5 descriptors are returned from open(). If I not use term_con at all, and not open vc0 three times as above, read(0, ....); and write(1,....); works but strangely. For example, read() returns immediately with no error and returns a single symbol (EOF, I think). But as I tested in Linux and OS/2 operating systems, when stdin is a console, read(0,...); must block until '\n' is returned (user pressed an Enter key). So, it seems that the file descriptors 0, 1, 2 are reserved, but they are not working as expected. Maybe, my setup is incorrect or something is not yet implemented? I have a menu.lst entry like this: title The "Hello, world!" program kernel $(A)/bootstrap -serial modaddr 0x02000000 module $(B)/fiasco $(FIASCOARGS) module $(B)/sigma0 module $(B)/roottask \ task modname 'simple_file_server' attached 6 modules module $(B)/log module $(B)/names module $(B)/dm_phys module $(B)/l4io module $(B)/rtc module $(B)/l4con module $(B)/simple_ts -t 300 module $(B)/name_server module $(B)/term_con module $(B)/simple_file_server -v 14 module $(B)/os2/config.sys module $(B)/os2/mini33.exe module $(B)/os2/minicmd.exe module $(B)/os2/msg.dll module $(B)/os2/doscalls.dll module $(B)/os2/sub32.dll module $(B)/fstab \ -c /file \ -c /file/system -v 14 -b / -m /file/system \ -c /vc -v 132 -b / -m /vc module $(B)/os2/os2server -d c: -m /file/system vbeset $(VBE_MODE) I needed to relink a term_con server to an address 0x01450000 instead of the default one of 0x01400000 because the latter was the same as with simple_ts server (0x01400000 too). I was not able to use loader server to load at other address because I needed to launch two l4vfs servers, term_con and simple_file_server where simple_file_server serves all files through fprov_proxy file provider (I don't want to use an extra bmodfs server to serve files for loader -- it would be an ugly decision, I think). The 'os2server' server uses the files that were served by simple_file_server and it tries to use l4vfs servers for reading from stdin. My makefile looks like this: PKGDIR ?= ../.. L4DIR ?= $(PKGDIR)/../.. TARGET = os2server # the default relocation address. This may be superseded by a STATIC file. DEFAULT_RELOC = 0x01800000 # list your .c files here # os2server.c SRC_C = main.c utility.c io.c MountReg.c globals.c native_dynlink.c l4_alloc_mem.c \ Shared/token.c \ Shared/modmgr.c \ Shared/ixfmgr.c \ Shared/ixfmgr_lx.c \ Shared/ixfmgr_lx_load.c \ Shared/ixfmgr_ne.c \ Shared/ixfmgr_lx_fixuplx.c \ Shared/ixfmgr_lx_loadobjlx.c \ Shared/ixfmgr_lx_modlx.c \ Shared/ixfmgr_lx_execlx.c \ Shared/ixfmgr_lx_debuglx.c \ Shared/memmgr.c \ Shared/api/apistub.c \ Shared/cfgparser.c \ Shared/processmgr.c #Shared/ow_dlfcn.c \ # if your server implements the server side of an idl defined in an idl-file # of your package, list the idl file name(s) here (no path needed) SERVERIDL = os2server.idl # list additional library paths and libraries here LIBS = -los2server -lparsecmdline -lthread -lcon -lcontxt -lconstream-server CFLAGS = -I$(PKGDIR)/include MODE=l4env_base include $(L4DIR)/mk/prog.mk Maybe some libs are interfere with l4vfs ones or something like this? I suspect the l4con server libs interfere with l4vfs libs. For example, l4con has its own getchar() implementation but in uCLibc this function is implemented through l4vfs backends. When I am trying to use getchar() or scanf() functions, I see that read() function is called behind the scenes, and it don't get blocked until Enter is pressed. So, any help is appreciated.

l4vfs and opendir()/readdir()
by Valery V. Sedletski 20 Jun '10

20 Jun '10

Hi all. I am trying to mount a flat file system by simple_file_server in l4vfs tree and then navigating over the file systen, i.e. opening/reading the root directory by opendir()/readdir(), searching the files in the directory and then opening them by open(). Doing this, I found that opendir() sometimes fails, trying to allocate a big (almost 2 gigabytes) dataspace at dm_phys. When I tried to compile my program and l4vfs servers with debug output, I had seen that this is done by calloc() function in opendir() function in l4\pkg\uclibc\lib\contrib\uclibc\libc\misc\dirent\opendir.c: if (!(ptr->dd_buf = calloc(1, ptr->dd_max))) { free(ptr); nomem_close_and_ret: close(fd); __set_errno(ENOMEM); return NULL; } before that, it makes fstat() and assigns ptr->dd_max to a FS block size from the stat buffer. After looking into l4vfs backends and simple_file_server, I had seen that the FS block size is left undefined, so it tried to use a big random value which appeared to be in a stat buffer. So, the fix can be simple -- set FS blksize to something (I set it to 512 bytes). And also, I added copying of that size from the stat buffer in stat() and fstat() functions in libc l4vfs io backend. So, my patch is attached to this letter WBR, valery

L4Re and Fiasco.OC
by Adam Lackorzynski 18 Jun '10

18 Jun '10

Hi, I'm happy to announce the availability of a major revamp of the Fiasco microkernel and the corresponding user-level infrastructure. Highlights include a completely new interface based on capabilities, support for multi-processor systems and virtualization. The runtime environment provides core servers and services, including a C++ and C programming environment, standard libraries (such as libc, stdc++, pthreads), programmable program launching and much more. http://os.inf.tu-dresden.de/Fiasco/ http://os.inf.tu-dresden.de/L4Re/ Adam

IPC error: resolved
by Valery V. Sedletski 08 Jun '10

08 Jun '10

I Finally understood the cause of an error. It appears that the stack of trampoline() task was the same as the one of LX executable being started. So, the LX executable had trampoline() local variables overwritten, and CORBA_Environment was corrupted ;) This is because IPC operation returned an error. Sorry for inconvenience, WBR, valery

IPC error
by Valery V. Sedletski 08 Jun '10

08 Jun '10

Hi all I am writing a program (API server which implements API and support for LX format executables found in OS/2 operating system). So, it parses an executable, applies fixups and starts it. At the moment it loads a simple executable which calls a single API printing a string on a screen. It generally works, but I got strange IPC problems. There is a function in a server, trampoline() which starts a previously prepared executable in a separate task (it is a kind of wrapper around that executable). After executable termination, trampoline() must synchronize with the server, passing it a message about termination. Then the API server can terminate itself. For synchronization, I tried two ways: 1) sending a message to main server thread through DICE interfaces. As I understand, a problem can be with that client and server stubs are linked to a single program. A code of trampoline() looks like that: static void trampoline(unsigned long esp_data, unsigned long eip_data) { CORBA_Environment env = dice_default_environment; l4_threadid_t dest; l4_msgdope_t result; l4_umword_t w0, w1; int err; asm( "pop %%eax\n" "pop %%eax\n" "movl %[esp_data], %%eax \n" /* Put old esp in eax */ "movl %[eip_data], %%ecx \n" "movl %%ebp, %%edx \n" /* Copy ebp to edx. Base pointer for this functions local variables.*/ "movl %%eax, %%esp \n" /* Copy eax to esp. Stack pointer*/ /* We have changed the stack so it now points to out LX image.*/ "call *%%ecx \n" /* Call our main() */ : :[esp_data] "m" (esp_data), /* esp+ data_mmap+8+*/ [ebp_data] "m" (ebp_data), /* esp+ data_mmap+8+*/ [eip_data] "m" (eip_data)); LOG("task end"); // query OS/2 server task id names_query_name("os2server", &dest) ; LOG("os2server uid=%x.%x", dest.id.task, dest.id.lthread); // send a signal about termination to OS/2 server env.utcb = l4_utcb_get(); os2server_wakeup_call (&dest, &env); if (DICE_HAS_EXCEPTION(&env)) printf("Error: %d.%d", DICE_EXCEPTION_MAJOR(&env), DICE_EXCEPTION_MINOR(&env)); } Without setting env.utcb to UTCB pointer, it traps because of null pointer dereferencing. (In os2server_wakeup_call() function code generated by DICE. This is the disassembly code: _os2server_wakeup_wakeup_wakeup_msg_buffer_t *_dice_msg_buffer = (_os2server_wakeup_wakeup_wakeup_msg_buffer_t*)_dice_corba_env->utcb->values; 1806a19: 8b 45 0c mov 0xc(%ebp),%eax 1806a1c: 8b 40 10 mov 0x10(%eax),%eax 1806a1f: 89 45 dc mov %eax,0xffffffdc(%ebp) l4_umword_t _exception __attribute__ ((unused)); l4_umword_t _dummy __attribute__ ((unused)); l4_msgtag_t tag_dummy __attribute__ ((unused)) = l4_msgtag(0,0,0,0); l4_msgdope_t _dice_result = { raw: 0 }; _dice_msg_buffer->wakeup_wakeup_in._dice_opcode = _OS2SERVER_WAKEUP_WAKEUP_OPCODE; 1806a22: c7 00 01 00 10 00 movl $0x100001,(%eax) -- it traps when assigning an opcode at the last instruction. I thought this is because of UTCB pointer in env points to OS/2 server's main thread UTCB but trampoline() executes in different task, so UTCB is other. When I added UTCB pointer, it stopped trapping but I got DICEexception with MAJOR code 2 and MINOR 2 (IPC error). On server side, a function os2server_wakeup_component() must be called which intended to reset a semaphore, on which a main thread waits for trampoline() termination: void DICE_CV os2server_wakeup_component (CORBA_Object _dice_corba_obj, CORBA_Server_Environment *_dice_corba_env) { LOG("wakeup called"); l4semaphore_up(&sem); } -- It never gets called because of IPC error in os2server_wakeup_call (). 2) Also, I tried another way -- there is a thread on the server side waiting for a message (I decided to create another thread besides the main one to not interfere with DICE): static void os2server_wakeup_thread (void) { l4_msgdope_t result; l4_threadid_t src, id; l4_umword_t w0, w1; /* because of l4thread_create(..., L4THREAD_CREATE_SYNC) */ l4thread_started(0); names_register("os2server.wakeup"); while (1) { LOG("waiting for message"); l4_ipc_wait (&src, L4_IPC_SHORT_MSG, &w0, &w1, L4_IPC_NEVER, &result); LOG("message received"); if (w0 == 0 && w1 == 0) { l4semaphore_up(&sem); LOG("semaphore reset"); } } } trampoline() code is modified this way: static void trampoline(unsigned long esp_data, unsigned long eip_data) { l4_threadid_t dest; l4_msgdope_t result; l4_umword_t w0, w1; int err; asm( "pop %%eax\n" "pop %%eax\n" "movl %[esp_data], %%eax \n" /* Put old esp in eax */ "movl %[eip_data], %%ecx \n" "movl %%ebp, %%edx \n" /* Copy ebp to edx. Base pointer for this functions local variables.*/ "movl %%eax, %%esp \n" /* Copy eax to esp. Stack pointer*/ /* We have changed the stack so it now points to out LX image.*/ "call *%%ecx \n" /* Call our main() */ : :[esp_data] "m" (esp_data), /* esp+ data_mmap+8+*/ [ebp_data] "m" (ebp_data), /* esp+ data_mmap+8+*/ [eip_data] "m" (eip_data)); LOG("task end"); if (!names_waitfor_name("os2server.wakeup", &dest, 10000)) LOG("wakeup thread not found"); else LOG("wakeup thread found, uid=%x.%x", dest.id.task, dest.id.lthread); w0 = 0; w1 = 0; err = l4_ipc_send(dest, L4_IPC_SHORT_MSG, w0, w1, L4_IPC_NEVER, &result); if (err) LOG("error: %ld", err); else LOG("message transmitted"); LOG("msgdope = %lu", result); LOG("mini33 exit"); } This way I get an IPC error too. The return code from l4_ipc_send() is equal to 16 but msgdope is clear (zeroes). I found a description of errors returned in message dopes but what means a return code of 16, I don't know. (For message dope, a error code of 0x10 means that source or destination does not exist, but I am sure it exists) So, l4_ipc_send() exits and l4_ipc_wait() on other side never exits. Maybe, someone can help understanding why it won't work? Thanks in advance.

Compilation errors with stl map in uclibc++

Hi All, I tried to run a small c++ application which uses stl map on top of fiasco. The application compiles and runs perfectly when compiled using standard c++ libraries. But when I try to create a package with this appilcation source code in tudos/l4/pkg (where compilation is done with uclibc++ instead of standard c++) I get few compilation errors. It would be great if someone gives some pointers on the error.

About consuming time slice on l4linux
by Jungwoo Yang 17 May '10

17 May '10

I know that l4linux cpu always is allocated on 4th thread on linux server. Also, I want to assign specific timeslice into the linux CPU thread to operate its linux kernel and its user task. To do this, I wanted to be expected in one of linux can use CPU more than another linux. However, even though I assigned timeslice more (it can be done by adding schedule context), 2 linux servers is seemed to be using almost same the amount of CPU. I think that this is because of idle thread. If idle thread is executed, other linux can preempt the linux. Am I right? also, I'm wondering whether user task consumes their own timeslice or donated timeslice from CPU thread. Thank you

Re: The system call about Periodic task
by Jungwoo Yang 13 May '10

13 May '10

I've found that this code is not wrong. The problem was from IPC control in thread-ipc.c in sys-ipc() function, the kernel check whether the ipc is next_period() or not, but the check function is wrong i think because the function returns always "FALSE". That means that there is no next_period() ipc. so I've changed the code in shared/entry_frame-ia32-ux.cpp line 110 return false; --> return (_ecx == 0x04000400 && _esi == 0); I'm not sure that this code does not affect to the other ipc. However it is executing quite well. Jungwoo Yang.

irq handling in DDE Linux26
by Da Zheng 12 May '10

12 May '10

Hello, In DDE Linux26, the interrupt is ignored when an interrupt line is disabled, i.e., the handle_irq field of ddekit_irq_ctrl is 0. In ne2k-pci, an example in DDE Linux26, when a packet is transmitted by the driver, disable_irq_nosync_lockdep_irqsave() is called to disable irq. Then it triggers a send and calls enable_irq_lockdep_irqrestore(). Now the problem is that after a packet is transmitted, the transmission-done interrupt can be delivered before enable_irq_lockdep_irqrestore is called, so the interrupt is ignored and the driver thinks the packet cannot be transmitted. This situation happens when I run ne2k-pci in the Hurd porting of DDE Linux26. disable_irq_nosync_lockdep_irqsave is exactly the same as disable_irq_nosync when there isn't CONFIG_LOCKDEP. It seems to me that ne2k-pci shouldn't call it in the first place when transmitting packets, but Linux drivers should be correct. Then what goes wrong? Should the interrupt handler delays interrupts instead of ignoring them silently when the interrupt line is disabled? Best regards, Zheng Da

Problem in porting an application
by Karthik Vadambacheri Manian 11 May '10

11 May '10

Hi Adam, My application uses Time Warped simulation library which uses standard c++ library. The time warped library uses a class called multimap which has a default constructor in std c++ library while in uclibc++ there is no default constructor. Hence to conform to uclibc++ I need to pass few arguments to use the current constructor in uclibc++ but this screws up a bit. I can modify multimap in uclibc++ with a default constructor but I am not sure whether default constructor is omitted intentionally and has some side effects. Also I need to do this change to all classes it is inheriting. Thats why I thought is it possible to use std c++ library instead of uclibc++. Can I know the version of std c++ library that is ported to uclibc++? Thanks a lot for your comments. Regards, Karthik

Re: Problem in porting an application

Just so you know, I was a big person in information when it was centered in my home city of NY. Just as NYC's tech industry collapsed (mostly, I believe because of the bombing of the WTC--which itself was a headquarters of free software), I was completing the design criterion of the Thinman model, which is an extension of Perl's CPAN to a VM that is open to the Internet for both data and code. It is anti-app in that each object, presumably a dataset, is, as it is evoked, its own app. Your friends list, as a small example, becomes a phone book in a flexible browser, when it is evoked in the context of a phone call through a model or other connection. I personally know David Korn, which is significant to me, since I believe that his KSH, with its related commands and related shells such as BASH, has provided the best work, and play, environment we have. It has a little awkwardness (which is forgivable given it was a proof of concept at its inception in the 1970s), and no OO version Shell has been attempted. And needless to say, it lacked a visual desktop! Other than those few issues, I cannot help but believe his traditional open shell still provides a model of the type of interactive framework that we need to bring to L4 as the default interface. I have since taken social science paths, and perhaps because of this, I very much want to help work from the top down (as you are with your ground-breaking port) to the lower levels, where everybody else is, so that L4 growth can be what free software is really all about--our system!

Hi All, Currently I am trying to port a pingpong c++ application which uses time warped libraries. The time warped libraries use standard c++ library inturn. I tried to compile the pingpong application by modifying the makefiles to include the time warped headers. But I get lot of errors while compiling because during compilation the uclibc++ header files are used instead of standard c++ headers and they differ. Hence I tried to port the warped library functions for uclibc++ but it seems it needs a huge modification. Do modifying makefiles to use standard c++ header files instead of uclibc++ will break other systems? Please let me know your comments. Thanks, Karthik.V.M.

Re: Regd: L4 Reference and User manual

Hi, after looking at the slides you pointed to (at http://www.inf.tu-dresden.de/index.php?node_id=1314&ln=en) the Fiasco for download isn't the one discussed in the slides, right ? So it seems that stuff discussed in your lectures are newer than that what is available for download, esp. the capability part. Also in your recent publications you are speaking about Fiasco.OC and L4Re and not about Fiasco 1.2 and/or L4Env. So what does this all mean ? They are related or is that completly new stuff and just rebranded to known/established names. Some enlightenment would be nice. (Intention of my mail: Try to figure out whether it is worth to start porting stuff to old? outdated? Fiasco 1.2 or to wait [how long?] for the newer stuff you discussing in your slides. Don't want to write or to port stuff twice, probably also interesting for the request of the MPI stuff some days ago.)

The system call about Periodic task
by Jungwoo Yang 28 Apr '10

28 Apr '10

I tried to use time periodic task designed by Udo. However, the process using the system call does not enter into periodic mode. So I tried to analyze kernel source code. During examining kernel source code, I found the wired point. line 584 in syscalls.cpp regs->old_param (dst->begin_periodic (regs->time(), 0)); I think that the parameter should be "Periodic" instead of 0. Because the point is for entering periodic mode and 0 means that conventional mode, I think 0 should be changed into "Periodic". After modification of this, A task using the system call enters periodic mode ( I check this by using JDB debugger ). I cannot ensure that this is correct code, but It seems to be working. So, if anyone who want to use periodic task and think that it is not working, just try to modify this code. Thank you for Adam Lackorzynski and Cheng Cuanghui Thank you. Regards, Jungwoo Yang.

Porting an MPI based appilcation on L4 feasible?
by Karthik Vadambacheri Manian 26 Apr '10

26 Apr '10

Hi All, I am new to L4 fiasco and microkernels in general. I could build the l4 fiasco microkernel and run the 'hello' application on top of l4. I also could run the hiworld client server application on l4 based on the available tutorials. Currently I have a pingpong simulation application which uses MPI and Time Warp libraries. For my research I would like to run this application on l4. Is porting it to l4 feasible? I also found a pinpong application in '../kernel/fiasco/src/test/pingpong'. But building fiasco microkernel does not build it. How to build it? and run on top of l4? Thanks for your time, Karthik.V.M. PhD student, Experimental Computing Lab, University of Cincinnati

Hello, I'm a student who are studying periodic task on L4, so I'm trying to use your cpu_reserved example. However, what I tried to use res_rt_sched or periodic. I've gotten some errors. title Fiasco Periodic Test kernel /bootstrap -serial -modaddr=0x06000000 module /fiasco -serial_esc -comport 1 module /sigma0 module /roottask task modname "cpu_reserved" allow_cli task modname "res_rt_sched" allow_cli module /events module /names --events module /log module /dm_phys module /cpu_reserved module /res_rt_sched This is my configuration of grub. but I have gotten some error like that. res_rt_s| Error: l4_rt_next_period(): Unknown (unregistered) error res_rt_s| [A.3] cpu_reserve/examples/res_rt_sched/main.c:77:worker(): res_rt_s| Error: l4_rt_next_period(): Unknown (unregistered) error res_rt_s| [A.3] cpu_reserve/examples/res_rt_sched/main.c:77:worker(): When I tried to figure out the error. The problem is from "l4_rt_next_period()". It returns 0x20 error "L4_IPC_RETIMEOUT". I've found the error from "l4cpu_reserve_wait_periodic()" in cpu_reserved server. The function returns 0 if the IPC returns "L4_IPC_RETIMEOUT", so I thought that "L4_IPC_RETIMEOUT" is not real error at that time. But when I execute the compoent "res_rt_sched", it look like that it is not a periodic task. I've spent about 3 weeks because of this.. please help me! Thank you.

In linux26/lib/src/arch/l4/pci.c, void pci_set_master(struct pci_dev *dev) { CHECK_INITVAR(dde26_pci); WARN_UNIMPL; } Were there any reasons that pci_set_master() was implemented? It seems pci_set_master() only needs to read or write the PCI configuration space. Best regards, Zheng Da

a bug fix in dde linux26
by Da Zheng 07 Apr '10

07 Apr '10

Hello, There is a small bug __kmalloc in DDE Linux26: when the memory is allocated by ddekit_large_malloc, the memory isn't set to zero even when __GFP_ZERO is set. It could cause some potential problems. For example, when a programmer calls kzalloc to allocate memory, he wants a piece of memory that has been set to zero. When I ran e1000 in DDE Linux26, this bug caused a big problem. Best regards, Zheng Da

Hello and make problem
by Leonardo Lazzaro 28 Mar '10

28 Mar '10

Hello, Today I started to read about l4linux and I wanted to build the l4-kernel. I tried to follow the steps at l4 webpage, now I am running ubuntu 9.10 and i am getting this error at make configure: error: You will need at least bison version 2.1a (found 2.4.1). Since it dont have too much sense (at least lower version but it found newer one) I suscript to the list to report this problem. Its important to know that : I found the l4-linux via google, download the code via svn trunk and follow the steps at the webpage. all this took me like 15min (found and tried to make, not compilation time) so I didnt read any docs (I should do it before send this email). I dont know if this kernel will work under ubuntu, and I think I will find more problems ahead. If anyone could recommend docs to read (or better the order to read them) about l4kernel. Sorry for bad english!

[ANNOUNCE] NOVA Microhypervisor 0.1 prerelease
by Udo A. Steinberg 08 Mar '10

08 Mar '10

Hi, The NOVA project is happy to announce that there is a prerelease of the NOVA microhypervisor available for download at http://www.hypervisor.org/ or http://os.inf.tu-dresden.de/~us15/nova/ under the terms of the GNU Public License version 2. NOVA is based on a modern microhypervisor written in C++ and assembler. It currently supports x86-32 SMP platforms with hardware virtualization features, such as Intel VT-x or AMD-V, and facilitates running multiple unmodified guest operating systems in virtual machines with near-native performance. On machines without VT-x or AMD-V, the functionality is reduced to that of a microkernel. Like third-generation microkernels, the NOVA microhypervisor uses a capability-based authorization model and provides only basic mechanisms for spatial and temporal isolation, scheduling, communication and delegation of platform resources. Additional services are provided by an unprivileged multi-server user environment running on top of the microhypervisor. In NOVA, we implemented almost all of the virtualization functionality in a deprivileged user-level virtual-machine monitor. This design choice improves the overall security of the system, because exploitation of a bug in the platform virtualization code only compromises the VMM and leaves the remaining components unaffected. Cheers, - Udo

Re: A question about the softirq implementation in DDE Linux26

In my current porting, I already raise the priority of the irq handler, but it doesn't solve the problem. I am thinking of using a lock to simulate cli/sti. When local_irq_enable() or local_irq_save() is called, we hold the lock; when local_irq_restore() or local_irq_disable(), we release the lock. We can even provide nested locking support if local_irq_enable() or local_irq_save() is allowed to be called multiple times in the same thread. Best regards, Zheng Da

A question about the softirq implementation in DDE Linux26
by Da Zheng 27 Feb '10

27 Feb '10

Hello, After I ported DDE Linux26 to the Hurd, I test it with a NIC driver: pcnet32, and see a problem: device interrupt of the NIC device is sometimes masked but cannot be unmasked. Whenever pcnet32 driver receives an interrupt, it masks device interrupts and calls __netif_rx_schedule() and let softirq to handle the interrupt. __netif_rx_schedule() should set NET_RX_SOFTIRQ, but it can only do that when the local "irq" is disabled (by calling local_irq_save macro). Linux disables irq with cli instruction. Obviously DDE cannot do that, but the implementation of local_irq_save in DDE is quite strange. It seems that it eventually calls raw_local_irq_disable(), which is implemented in linux26/lib/src/arch/l4/cli_sti.c. How can increasing _refcnt has anything to do with disabling irq? Without disabling irq, there is a race condition in the interrupt handler and softirq handler. When I run pcnet32 with my ported DDE Linux26 for a long time, I sometimes see softirq fails to be scheduled after the driver receives a hard IRQ. I don't know how the Linux drivers can work with DDE Linux in L4. raw_local_irq_disable() apparently has problems if I read the right code. Best regards, Zheng Da

Announcement: Genode 10.02 adds support for the NOVA hypervisor
by Norman Feske 24 Feb '10

24 Feb '10

The Genode project has released the new version 10.02 of the Genode OS Framework. The framework is a modular user-level infrastructure comprising device drivers, a GUI, networking support, a C library, and Qt4. It can be executed directly on different microkernels, in particular L4/Fiasco. Starting with the current release, we include support for the recently released NOVA hypervisor into the official Genode distribution. So there are now two kernels of the Dresden OS group ready to use with the framework. For the technical details of our porting effort, please refer to the release notes (see the link below). Moreover, we added support for the Codezero kernel and introduced a new concept for managing real-time priorities on the L4ka::Pistachio and OKL4 kernels. The most significant new functionality is the initial port of the Python 2.6.4 script interpreter. Release-notes summary for version 10.02 --------------------------------------- * Platform support * NOVA hypervisor * Codezero kernel * New thread-context management * Real-time priorities * Python scripting You can find the complete release notes for the version 10.02 here: http://genode.org/documentation/release-notes/10.02/ The new release is available via the project's subversion repository and at the Genode download page: http://genode.org/download/latest-release Regards -- Norman Feske Genode Labs http://www.genode-labs.com · http://genode.org

Fiasco reserved memory area overlapping with bootloader area
by Christian Prochaska 14 Feb '10

14 Feb '10

Hello, I recently had the problem that a physical memory area reserved for Fiasco overlapped with a Bootloader area, resulting in one or possibly more corrupted boot modules. Apparently there was not enough physical memory available, but i would suggest that in this case Fiasco would print an error message and stop as soon as it knows about the overlap instead of further executing the corrupted modules.

Interrupt problems causing crash of network driver and Kernel panic?
by Andreas Speier 08 Feb '10

08 Feb '10

Hi L4-Hackers, I got problem running L4Linux 2.6.29 on Fiasco with a time critical application (Asterisk). The main hardware components are an embedded board with 1GHz VIA C7 processor, 1GB of RAM and 2 network interface cards (VIA-Rhine, 3Com). The drivers are compiled into the L4Linux kernel. Running this application works fine until some more interrupt intensive process will be started. Then the VoIP communication (SIP) breaks down and I got the following output in /var/log/syslog: ################# Jan 28 08:24:58 TESTPC kernel: ------------[ cut here ]------------ Jan 28 08:24:58 TESTPC kernel: kernel BUG at /home/[...]/l4linux-2.6.29/net/core/dev.c:2625!

fiasco - related
by sarita kale 29 Jan '10

29 Jan '10

I have to select one of the micro-kernels for further development. I need answers to following questions to go forward: - What are the limitations/advantages of Fiasco, L4Ka: Pistachio and OKL4. Which one should I select? - Is Fiasco still alive? When I visit Fiasco http://os.inf.tu-dresden.de/fiasco/ site, last updated date is 26 Sep 2005 *Fiasco 1.2 released!* Do we have further releases or is it stopped? - Does anyone have performance figures of Fiasco, L4Ka: Pistachio and OKL4, based on which i can decide which micro-kernel to go for? - Does L4Linux work on OkL4, I read L4Linux runs of L4Ka: Pistachio, will it run as it is or we need to make some changes to it? Thanks Sarita

DDE Linux26 in the Hurd
by Da Zheng 29 Jan '10

29 Jan '10

Hello, I have managed to port DDE linux26 to the Hurd. At least it works with NIC drivers now. A few problems: 1. dde linux26 doesn't support multiple PCI buses. Unfortunately, my virtual machine has two PCI buses: bus 0 and bus 2. Now I have to hardcode the bus numbers in the code. Do you have plan to support multiple PCI buses? 2. DDE Linux26 doesn't support sound card drivers. Does DDE Linux26 support the block device and character device? Zheng Da

Call for participation to the Alt-OS devroom at FOSDEM (Extended deadline)
by François Revol 02 Jan '10

02 Jan '10

Hello, This year, the FOSDEM (in Brussels, 6-7th February 2010) will host the "Alt-OS" devroom on sunday from 9:00 to 17:00. This devroom is meant as a place for Free and OpenSource Alternative Operating System projects to share ideas and work on topics like: * distinguishing design and features, * device drivers and how to share them, * sharing code for internal components, * internal usage of other FOSS projects to build upon, * application portability, * interoperability, o file formats, o extended attributes... We are very interested to hear about your project on all those aspects, and of course we'd be happy to help you set up a hacking session or other form of gathering eventually, depending on the schedule. See the complete call for participation. http://groups.google.com/group/rosetta-os/browse_thread/thread/16964e21bef2… The deadline for the propositions for the Alt-OS devroom at FOSDEM has been extended to 2010-01-05, to allow at least one talk per project. The shedule must be sent rapidly to the FOSDEM team so we can't stretch it much more. François.

Codezero Microkernel v0.2 Released
by Bahadir Balban 07 Dec '09

07 Dec '09

I would like to announce that Codezero Microkernel v0.2 is released. On this release, the microkernel is now fully capability checked, and we introduced the notion of containers to provide isolated execution environments. Please see below for a brief description. 1.) Containers In Codezero containers provide the architectural infrastructure for isolation of execution environments. Each container is allocated with a set of address spaces, threads, and any other resource that would otherwise be globally available on the platform, such as virtual and physical memory. Using the simple notion of containers, it is possible to build any type of software design hierarchy. A hierarchical client/server design, or multi-threaded standalone applications are both possible scenarios. 2.) Capabilities Capabilities protect all resources maintained by the kernel. Currently, all system calls are protected by capabilities, except a few trivial ones that have been left out. Physical and virtual memory, typed memory pools, and inter-process communication are among other resources that are protected by capability checking. Capabilities build upon the foundation of containers, providing a fine-grained security architecture, inside and among container boundaries. We also introduced a capability control system call, by which the capabilities may be shared, granted and modified in different ways, enabling a highly flexible and configurable security architecture. 3.) Configuration We attempted to present the above two notions in an easily manageable kernel configuration system. Containers, their parameters and capabilities may be adjusted easily at configuration time, using our CML2-based kernel configuration system. We are aiming to evolve the L4 API into the future by feedback, hence this email post. Codezero Project is open with a GPLv3 license. If you are interested to learn more, download by: git-clone git://git.l4dev.org/codezero.git A useful jump-start guide: http://www.l4dev.org/doku.php?id=getting_started_quick API reference man pages: man -M codezero/docs/man pagename Thanks, -- Bahadir Balban

ddekit and dde linux2.6
by Da Zheng 22 Nov '09

22 Nov '09

Hi, I'm trying to understand ddekit and hopefully to port it to Hurd. It seems that ddekit is still under active development. What is its current development status? I read http://demo.tudos.org/dsweeper_tutorial.html, which said that new features such as hotplugging and power management would be added ddekit but it was in 2006. Have those features been added to ddekit? Is it possible for me to move the Linux USB driver on the top of dde without modification? What is the status of dde linux2.6 (I mean the one in the directory l4/pkg/dde_linux26)? Is it still under development? Does it support the features I mentioned above? Thank you, Zheng Da

Hello: I tried to map the hpet iomem to the virtual memory but i got some error. The log is as following: vtimer | rmgr_pager 4:0 vtimer | hpet_address 0xfed00000 vtimer | hpet size 0x400000 vtimer | hpet_virt_address 0x400000 ROOT: Cannot map page at fed00000 log2_size=12 failed vtimer | IOMem mapping error : No fpage received vtimer | __handle_pf(): L4RM: page fault: no entry in region list vtimer | L4RM: [PF] read at 0x00400000, ip 0100024e, src 8.02 It seems that when I map the iomem the pagesize is not permitted but superpagesize is ok. But i still get the error as "No fpage received". Does anybody tell me what the problem is? Thanks. Cheng Guanghui

Some Errors in DDE
by Jingyi WANG 30 Oct '09

30 Oct '09

hi, I'm porting a sound card(ens1370)to DDE, but found some errors in the function of kobj_map whic is in map.c(l4/pkg/dde/linux26/contrib.drivers/base/map.c) What's more, I check the ELF format of this sound card.The error is in the address of 821607. The related messages show as follows: /home/wangjingyi/l4/tudos/l4/pkg/dde/linux26/contrib/drivers/base/map.c:58 mutex_lock(domain->lock); 821603: 8b 55 08 mov 0x8(%ebp),%edx 821606: 58 pop %eax 821607: 8b 82 fc 03 00 00 mov 0x3fc(%edx),%eax 82160d: 50 push %eax 82160e: e8 cd 65 02 00 call 847be0 <mutex_lock> I was wondering what caused this error and how to fix it. Thanks!

ex_regs system call is forzed in the do_ipc process
by Guanghui, Cheng 23 Oct '09

23 Oct '09

Hello: When i use the ex_regs system call to trigger the exception ipc it seems to be frozed in the do_ipc stange. I use jdb to debug this current thread lists is like this: 9.04 l4ertl.exceptio 10 9.03 rcv,ipc_progr 9.03 l4ertl.timer0 10 9.02 rcv,ipc_progr 9.02 domain2.main 10 9.04 rcv,ipc_progr,exc_progr l4ertl.exceptio is the pager of domain2.main. And now l4ertl.timer0 is executing ex_regs system to trigger exception for domain2.main. l4ertl.exceptio is waiting for the exception ipc from the l4ertl2.main2. In detail l4ertl.exceptio is in ipc (user level registers). l4ertl.timer0 is in ipc (user level registers), too. domain2.main is in the exception 255. It seems to be dead lock in the kernel. Very strange. Thanks. Cheng Guanghui

20 Oct '09

Hi~When I run a device driver on DDE(pkg/dde/linux26/example), the result shows up that pci_set_master() and pci_disable_device is unimplement. Could you give me some advice on how to make these functions work?

Hello, Adam: Now the demo could work according to your design. And this demo is so simple only to emulate the situation we talked about before. I introduced a little about this demo: 3 threads: timer_thread, exception_thread, main_thread main_thread emulates the behaviour of system which is a endless loop to output. the function body is thread_func1. timer_thread emulates the behaviour of timer thread which could trigger the exception periodically. exception_thread emulates the behaviour of handling interrupt. The function body is exception_handler. When the timer_thread modify the status of main_thread with flag L4_THREAD_EX_REGS_RAISE_EXCEPTION. The main thread will be suspend and the exception_thread could get the exception ipc from main_thread. Exception_thread will modify the ESP and EIP in the utcb and then reply to main thread. The main thread will resume to the function about handling interrupt. When the handling interrupt function is over. The main thread could go back to the status before the exception happens. The output: count 49 ... count 58 id: 8:1, 12 0xeacff011 15 0x100711c do irq 0 ... do irq 9 l4_sleep(): IPC error 00 count 59 ... count 67 id: 8:1, 12 0xeacff011 15 0x100711c The output between "count ..." is execution of main thread. The output between "do_irq ..." is execution of exception thread which emulates the interrupt handling. BUT. I have a problem about my code when i fixing the stack of main thread. The correct code which could work well is like this: utcb = l4_utcb_get(); eip = utcb->exc.eip; esp = utcb->exc.esp; utcb->values[12] = (l4_umword_t)(do_irq); esp_loc = 1024 - (esp - (l4_umword_t)stack)/4; stack[esp_loc - 1] = eip; l4_msgtag ... l4_ipc_send_tag In the code above i only reset the next stack with return address (old eip). But it seems i can't reset the new stack pointer like utcb->values[15] = esp - 4 In my opinion it should do but if i did it can't work. It seems some tricky here. Can you tell me why it is like this? Additinally, i tried this way about handling interrupt with interrupt number like this: void do_irq(int irq) it can't work either. Thanks. Cheng Guanghui

Split console with two keyboards
by Shakthi Kannan 16 Oct '09

16 Oct '09

Hi, I would like to know if it is possible in any of the L4* systems to have a setup like the following: * The console (framebuffer) to be split into two frames/windows, say top and bottom halves, but, each one should be used/accessed independently of each other. * With two keyboards connected to this single system, one should be able to use (shell) one of the keyboards with the top window, while the other should use the bottom one. Appreciate any thoughts/inputs in this regard. Thanks! SK -- Shakthi Kannan http://www.shakthimaan.com

About the exception ipc reply
by Guanghui, Cheng 14 Oct '09

14 Oct '09

Hello: From the l4-x2 manual it is said the reply from the exception handler contains a label, an instruction pointer where the faulting thread is resumed. I want to know whether it is implemented in the Fiasco. I try to do this. Modify the utcb before send ipc resume the exception thread but it seems no any effect about the instruction pointer and stack pointer of resumed exception thread. Thanks. Cheng Guanghui

Back to UTCB IPC
by Marc CHALAND 11 Oct '09

11 Oct '09

Hi, I am back with my problem with UTCB IPC. To sum up the context : I use pure l4env applications. Here is the scenario between my server and my client : 1. client makes an UTCB IPC to manager. Manager does an l4rm_area_reserve, creates a rcv_fpage, creates worker and sends back worker thread id to client. 2. client allocates memory and associated flexpage and sends it to server. 3. UTCB IPC is sent to worker with 3 parameters : - on client side : utcb->values=0xbff00200: arg1=0x2 arg2=0x1 arg3=0x6 - on server side : utcb->values=0xbff00200: arg1=0x241401 arg2=0x0 arg3=0x7069776c It seems that 0xbff00200 is not mapped on the same memory on client and server side. As there is no problem for first IPC (utcb->values is also 0xbff00200), is there any potential problem with flexpage ? As utcb->values is still the same, what happens if several threads try to make UTCB IPC ? Another question : when I link my application with liblogserver.a, I have strange logs : .rm.sem.mainMain function returned. It seems that .rm .sem and .main are added by l4env, but I didn't find where. Regards Marc

Maybe we can use the two registers in the Exception IPC as Pagefault IPC
by Guanghui, Cheng 10 Oct '09

10 Oct '09

Hello: In the present implementation of exception ipc the two registers are not used but only given with 0. It seems a little bit waste. I mean in the page fault ipc the two registers include address where page fault occurs and instruction pointer which causes the page fault. Can we make exception ipc includes two registers with the next/current eip and esp? It seems not to be bad for this system call because it is a little bit strange that this exception ipc doesn't includes anything useful. Thanks. Cheng Guanghui

Pagefault by running L4Linux 2.6.29 on Fiasco
by Andreas Speier 30 Sep '09

30 Sep '09

Hi L4-Hackers, I have some serious problems running L4Linux (linux-2.6.29-l4) on Fiasco. As the attached serial output shows, the L4Linux startup ends with a page fault error. Unfortunately I have no clue why this error happends and hope that one of you can help me solving it. Both, Fiasco and L4Linux have been compiled on an Ubuntu 9.04 system, using the gcc-3.4.6 (same with gcc-4.3) compiler. Thanks in advance!

is it possible to check the register info change before and after one system call for one thread?
by Guanghui, Cheng 17 Sep '09

Hello: i want to know whether to know the register info changes before and after one system call for one thread. Especially, the l4_thread_ex_regs could change the pc of one thread. I want to know the status of other registers after this system call. is it possible to use jdb to get this? Thanks. Cheng Guanghui

About the JDB debugger
by Guanghui, Cheng 15 Sep '09

15 Sep '09

Hello: Is there method to check the registers viaration info before and after one special system call for one thread with the help of JDB. I checked all the options but i can't find one. What i want to know is about the l4_thread_ex_regs system call. We know it could modify the instruction pointer, stack pointer and pager thread or get the current instruction pointer, stack pointer and pager thread. When we modify the instruction pointer to a new one but put the stack pointer the same i want to understand what happens in this thread stack. Thanks. cheng guanghui

the __main symbol in the crt0_x.S
by Guanghui, Cheng 09 Sep '09

09 Sep '09

Hello: I checked the crt0_x.S in the crtx package and find something interesting. In the crt0_x.S the main function is named __main() but not main() normally. But in the normal function we still use main() but not main() i want to know where to address with the symbol __main() by the address of main() in the real application. I look around the crtx package, mk directory and libgendep.so unluckily i don't find it. thanks a lot. Cheng Guanghui

My problem of I/O port
by Ding ying 02 Sep '09

02 Sep '09

Hello,everyone: I have built a parport server based on dde, and test it through on fiasco. Now I want to booting it together with l4linux, but there are conflict occured. And I have some questions to ask: 1. I used the l4linux-2.6.30 kernel, now to booting it besides fiasco default config, there is [ *] Enable I/O port protection feature must need, isn't it? It not needed in l4linux-2.6.23 kernel or earlier. 2. Will this feature prevent the other server to access to the io port? I seems meeting this problem, my parport server(#b) want to access the port 077a, but system say the owner is #a(l4io), even I set the parport priority higher than l4io, it also the same problem. the last error message is like follow: ............................... server | <6>parport0: PC-style at 0x378 [PCSPP,TRISTATE] server | <6>parport0: irq 7 detected ROOT: Cannot send port 077a to task #0b, owner is #a ROOT: task B.00 at 01804299 is trying to get I/O port 077a allocated by task 0b. ................................ How can I do could make the parport server run together with the l4linux, or to make it could access the port it needed? Any help is precious. Best Regards! ding

I know that when I use open()/close() in the client side, the server will call the function open_component()/close_component() which are in the server side. In the open_component()/close_component() function I want to get thread id of the caller to do some operation flag.but as we know, when we call open()/close() in client side, the open_component()/close_component() function in server side will be executed. so we can not use l4_ipc_wait() or l4_ipc_reply_and_wait() function in the open_component()/close_component() function, or it will be stop and wait for a message in the function. So in order to get the thread id in the open_component()/close_component(), when or where should I use the l4_ipc_wait() or l4_ipc_reply and wait() to get the thread id? thank you! -- fang,

hi all, I want to write a simple example in l4, and there are to task module: client,server in the client side, I use the interface which is inplemented in server side.like: int open(int fd, int flags) I know that the client side can get the server's thread_id throw name service. I want to ask can the server side get the client's task_id or thread_id? or must the client side send the thread_id to server? thank you. -- fang,

one question about l4_thread_ex_regs flags
by Guanghui, Cheng 26 Aug '09

26 Aug '09

Hello: About the l4_thread_ex_regs system call there are 2 flags related with exception ipc. I only know the thread with these flags could generate the exception ipc but i don't know what is the difference between these flags: L4_THREAD_EX_REGS_RAISE_EXCEPTION , L4_THREAD_EX_REGS_ALIEN and L4_THREAD_EX_REGS_ALIEN | L4_THREAD_EX_REGS_ALIEN. So, i write a following program to test the behaviour with different flags : void idle(void *data) { l4_sleep(1000); l4_sleep(1000); l4_sleep(1000); l4_sleep(1000); l4_sleep(1000); } int main() { ... l4_threadid_t me = l4_myself(); l4thread_create(idle, NULL, L4THREAD_CREATE_ASYNC); ... l4_thread_ex_regs_flags(idle_thread, ~0UL, ~0UL, &_preempter, &me, &o, &o, &o, L4_THREAD_EX_REGS_RAISE_EXCEPTION | L4_THREAD_EX_REGS_ALIEN); while(1) { l4_ipc_wait(&src, ...); printf("thread :%d:%d\n", src.id.task, src.id.lthread); } } I tried 3 combination about these 2 flags but the output is the same as this: exceptio| thread :8:3 i don't know why there is only one exception ipc. But the idle function includes 5 system calls. Additionally, it seems the ALIEN state is TEMPORARILY. I set once there is one exception ipc, twice two exception ipc. Can you explain me? Thanks.

seL4 kernel is formally verified
by Gernot Heiser 18 Aug '09

18 Aug '09

Hi, For those out there who missed the publicity (incl ./): NICTA announced last week that the formal verification of our seL4 kernel has been completed. This makes seL4 the first ever general-purpose OS kernel with a formal proof that the implementation is consistent with the specification. A paper on the project will appear in this year's SOSP. Details at http://ertos.nicta.com.au/news/home.pml#verified Gernot

Howto implement a periodic real-time task?
by Andre Puschmann 10 Aug '09

10 Aug '09

Hey guys, I got a L4 real-time application that should run strictly periodic. In each cycle I have to communicate with at least two other L4 threads in different address spaces. The cycle period is in the order of 1000Hz to 5000Hz. As described in [1] I tried to use the CPU reservation server but the sample implementations did not work. Anyway, I figured out that even the CPU reservation server depends on the kernel timer and thus the granularity is 1ms (in PIT mode), which is too coarse for cycle periods larger then 1000Hz. Although I like the idea to use OS primitives to keep the application as portable as possible (ARM port is a goal), I thought about implementing the periodic execution with an extra timer decoupled from the scheduling timer which generates an IRQ at each hit. Any comment/suggestions/ideas about that? Any other experience with periodic real-time tasks on L4? Cheers, Andre [1] http://os.inf.tu-dresden.de/pipermail/l4-hackers/2009/004179.html

Re: problems running l4linux No.2

Hi, I started from a default l4linux26 kernel config. I did not touch anything, except for the things I had to, like acpi, apic, MTRR, MCE .. and the stuff that is missing (olpc, scx200 and these things). Everything else is default.

interrupt registration
by eric johnson 04 Aug '09

04 Aug '09

i m using a pistachio L4 kernel. ( with no operating system on top. ) I am running this on an emulator ( qemu) . So i dont have a way of having real interrupts. There might be a way in qemu to do that , but i dont know how. My question is : i figure there is an interrupt thread for every interrupt. ? Since i dont have any real hardware i would like to have a interrupt thread for a random interrupt no. How do i make sure that this interrupt thread is created ? I am trying to simulate the behaviour of an interrupt processing in L4. suresh

Hi, I am still trying to run l4linux on top of fiasco. I am running it on top of a console system and configured L4Linux2.6 without any input drivers. Thanks to your suggestion I am loading vmlinuz with a start script. I can't tell you much, but once booted both serial and console are spammed with ... l4lx | l4env_phys_to_virt: Could not translate phys. address 0x94140 l4lx | l4env_phys_to_virt: Could not translate phys. address 0x94150 l4lx | l4env_phys_to_virt: Could not translate phys. address 0x94160 ... messages.

Hi, i am trying to run l4linux on top of fiasco. Using the cfg start script from the website to load vmlinux. But after that nothing really happens and the keyboard somehow gets redirected to my serial connection. jdb output is: loader | sleeping for 1000 ms loader | vmlinux: Starting sigma0-style application loader | vmlinux: Loading binary loader | vmlinux,#f: Entry at 00009c3c => 00400000 loader | vmlinux,#f: Started loader | DEBUG file = vmlinux loader | vmlinux,#f: Double PF (r) at 00000000 eip 00000000 (F.00) It seems to load quite ok, but nothing else. But I may have not payed enough attention to configuring the l4linux kernel. I know I tryed to turn off any serial drivers. Which part should have control over the keyboard? Thank you for your help. Kind Regards, Stefan

hi, I'm sorry to trouble you,but I have a question with X server when start l4linux on dope. I have search a mail which you have sent: > Yes, I know that this setup is not easy. For overlay_wm driver to work it is necessary to apply patches to X Server sources, as I read. But I thought it must work with linux server with ordinary l4con/dope frambuffer driver. So, it won't, ok. -- When I checked on real machine (not with ramdisk), l4linux started and XServer starts OK. > I can start l4linux on dope and con,and also on serial console.The below is what I use in l4linux.cfg: task "vmlinuz" "earlyprintk=yes mem=64M video=l4fb root=/dev/hda9 " all_sects_writable allow_vga allow_cli could you please tell me what I missing? thank you. -- fang,

Re: l4-hackers Digest, Vol 72, Issue 8
by fang zhengshu 08 Jul '09

08 Jul '09

hi all, when I write a function in the IDL file, there is a problem:want to write a different-length string to a array like: interface test{ int write([string]char* str, int len); int read([out,prealloc_client, size_is(size), prealloc_server]char str[], int size); }; I have defined a fixed size array in the server like array[256]. In the write() function I write a different length string to the array, then I want to read parts or all of the array in the read() function, the process will be like the following: string[len] str[size] | ^ | | --------->array[256] -----------| but when I put the function above and compile it, there are some error happen. I have change the size_is() with length_is() or max_is(), but there still error when I compile it. I know if I define a fix array str[256] the code can be work, but I just want to use a unfixed length array to get the string. could someone please give me some advice?if I describe the problem clearly, please let me know. thank you! -- fang,

running cpu_reserve examples
by Andre Puschmann 29 Jun '09

29 Jun '09

Hi list, I am playing with the examples in package cpu_reserve (i.e. res_rt_sched). However, for some reason the code doesn't work as expected. In the worker-thread the function l4_rt_next_period() returns error nr 32 which is an IPC error, I guess its waiting for a msg from the reservation server here. Here is the sample output (qemu log): Welcome to Fiasco(ia32)!

Invalid TCB Access for thread creation in L4Linux
by Sean 14 Jun '09

14 Jun '09

Dear all Now I try to add some functions and data structures in Fiasco. I had added several data structures into "class Context" and implement some functions to manipulate these data structures. My goal is to add multiple ready queues in Fiasco. So I add the corresponding enqueue function in ready_enqueue() to add the Context into my own ready queue. (But I don't change the way to choose highest Context, I only add the queue and try the functionality of these queue.) It seems to be valid for simple environment. But when I load L4Linux and I want to group all threads owned by L4Linux into my ready queue, it got some unpredictable page fault error. ------------------------------------------------------------------------------- ... mice: PS/2 mouse device common for all mice TCP cubic registered NET: Registered protocol family 17 Freeing init memory: 128K init started: BusyBox v1.13.2 (2009-05-13 02:16:43 CST) starting pid 13, tty '/dev/console': '-/etc/init.d/rcS' Fiasco BUG: pfa=c0440084 err=400017 pc=f001f14c --Fiasco BUG: Invalid TCB access (locked)------------------PC: f00080a8 [rcS] (10.00) jdb: ------------------------------------------------------------------------------- The error is caused from the enqueue function which changes the data structures in class Context. But the error sometimes happened before l4x.idler0 thread creation, sometimes I can get into shell correctly and error happened when I use unix commands (which creates new thread for this unix commands). The error is unpredictable. Because the other threads can work correctly, I guest that there are some issues in L4Linux to cause this error from the modification of class Context. Can anyone give me any idea? Thanks very much!! Best Regards, Sean

Thank you. I gave the idea a little thought, and I think that the next OS needs another layer on top of the UI technology that directly talks to the user. I think that to directly integrate the user into the system, there has to be some kind of mind-mapping interaction with the OS as part of the capabilities that are offered to the user in the UI. Beyond this, the user needs to integrate into the "cloud," which is the rest of society, through the mind mapping, which then becomes minds-mapping. (??)

More info on Microsoft Research: http://research.microsoft.com More info about Galen Hunt: http://research.microsoft.com/en-us/people/galenh/ Regards, Ron. -------- Original Message -------- From: Galen Hunt Sent: Thursday, June 11, 2009 8:51 Subject: MSR OS Group RSDE Position Friends, The Microsoft Research (MSR) Redmond OS group is looking for an RSDE. We're looking for someone who can code like the wind and is interesting in gaining great breadth of experience. I think no other group in Microsoft offers an equivalent opportunity to write OS, compiler, and tools code. As an example, one of the RSDEs in my group implemented ACPI for Singularity, most of an ARM JIT for the CLR, and a file system in the last two years. We're favorable toward candidates who want to do a tour of duty in MSR before jumping back to product, or want to build their experience and publication record before going to a top-five school for graduate work. If you know of anyone who would be interested, please ask them to contact me. Here is the job description: The Microsoft Research Operating Systems Group is looking for an exceptionally strong engineer (RSDE) to join our team. We are a tight-knit, world-leading research team with the charter of prototyping new OS-related advances and working closely with product teams on tech transfer. Our team frequently publishes in top conferences such as SOSP, OSDI, PLDI, and POPL. Three of 23 papers in SOSP 2009 were co-authored by members of our group. In the recent past, we built the Singularity OS, prototyped a file system for Phase Change Memory (PCM), published the first research on verification of practical garbage collectors, and experimented with new OS configurations for mobile computing. We are looking for a candidate with exceptionally strong coding skills and a passion to change the world. The ideal candidate will have a B.S. or higher in computer science or a closely related field and at least 3 years of experience either building product quality code or coding in a research environment. Experience with C, C++, and assembly is required. Experience writing kernel-level OS code or compilers is not strictly required, but highly desirable. While not strictly a requirement, preference will be given to candidates who can produce 1,000 lines of code or more per week when building prototypes. Interest and eagerness to work in a wide range of systems projects each year is highly desired. Internal candidates should have a high ratio of exceeded ratings on their annual reviews. Thanks galen

[ANNOUNCE] Introducing Codezero
by Bahadir Balban 11 Jun '09

11 Jun '09

Hi Everyone, I would like to announce my ongoing work on a new L4 microkernel called Codezero. Codezero is a modern L4 microkernel implementation written in C. It targets embedded platforms, supports the ARM architecture, and aims to implement both virtualization and native OS components in one system. Codezero has a design and API that is similar to existing L4 microkernels such as Pistachio. The software currently comes with two services: First one is the default pager called MM0 that provides memory management capabilities with a POSIX-like API. It supports proper demand paging and implements calls such as fork, clone, execve, exit, mmap, shm. The second service is called FS0 and it implements the virtual filesystem layer. This service supports calls such as open, close, read, write, lseek, stat, fsync, etc. The software comes with a GPLv3 license, and a copyright share agreement option for contributions. The source code base is fairly clean and easy to play with. I encourage anybody interested in development to join. For more details: http://www.l4dev.org Thanks, -- Bahadir Balban

The implementation of CPU reservation server
by Sean 08 Jun '09

08 Jun '09

Dear Now I am tracing the source code of cpu reservation server in l4/pkg/cpu_reserve directory. And I got several questions... 1. The bottom of cpu reservation server is implemented by l4_rt_add_timeslice(), l4_rt_set_period(), l4_rt_begin_strictly_periodic() functions. And these functions are defined in l4/pkg/l4sys/include/ARCH-x86/rt_sched-impl.h which calls l4_rt_generic() function. Function l4_rt_generic() is implemented by inline assembly, and it seems to call the system call "thread_schedule". Because these functions only appears in ARCH-x86 directory, do they support on ARM architecture? If not, how can I implement similar behaviors of these functions? Where can I find the document about the L4 system call API ? I can't really understand the behavior of these functions. 2. When system contains three user threads, I want to control Fiasco scheduler not to schedule one thread in these three threads during one time interval. How can I implement it? The simplest way seems to control this thread into un-running state. How can I achieve this by a supervisal server? I'm sorry for my poor English and lengthy question. I'm glad if you give me some hints or corrections. Thanks a lot! Best Regards, Sean

The behavior of scheduler in L4Linux on ARM architecture
by Sean 21 May '09

21 May '09

Dear Now I am studying the scheduler design issue of DROPS including Fiasco and L4Linux. In the reference document, "L4Linux Porting Optimizations", it said that " In an L4Linux system two schedulers are active. One is in the L4 kernel scheduling all L4 threads including L4Linux processes. The L4 scheduler uses static priorities and schedules threads with the same priority round-robin. The other scheduler is in the Linux server, deciding which Linux process to run next. L4Linux is designed in a way that from the view of the Linux server multiple user processes can be running in the L4 system. Furthermore, the Linux scheduler can only consider those processes that are blocked in the server. Consequently, the Linux server needs to distinguish between user processes being served by the Linux server and the ones running." For the behavior of the scheduler in L4Linux, I got some questions below. 1. In L4Linux, the process/thread will map to several L4 Threads. How the scheduler in the Linux Server considers user processes in L4Linux whether to execute in L4 system ? According to the document, does L4Linux scheduler only control the user process whether block or not? 2. Based on the L4Linux source code from currently SVN, the behavior of schedule() function (kernel/sched.c line 4546) is => If next != prev, call context_switch() function => In context_switch() function (kernel/sched.c Line 2649), it calls architecture dependent function switch_to() => In switch_to() function (arch/l4/include/asm/arch-arm/system.h Line 222), it calls l4x_switch_to() function and __switch_to() function => In l4x_switch_to() function (arch/l4/kernel/arch-arm/dispatch.c Line 170), it logs the message to Trace Buffer of Fiasco and set l4x_current_process => In __switch_to() function (arch/l4/kernel/arch-arm/switch_to.S Line 5), it store the registers to CPU context of thread_info and load all regs saved previously Based on the source code analysis, it seems that when the L4Linux scheduler decide to do the context switch, the architecture dependent function __switch_to() will do the register restore and load. According to the document, I think the behavior here should set the corresponding thread status of prev and next user process to block or unblock these L4 threads. But here it does low level register restore and reload operations to change the current running process directly. It confuses me. Can anyone give me any ideas to address this? Thanks a lot! Best Regards, Sean

USB Smartcard reader unter L4Linux
by Gianfranco Ricci 18 May '09

Hello l4hackers! I'm trying to set up an L4Linux environment in which a USB smartcard reader [ReinerSCT cyberjack e-com(a) ] can be used but I'm encountering problems. I'm using: L4Linux 2.6.22 with complete USB support libusb 1.0 usbutils 0.11 Driver 3.3.2Beta3 for the smartcard reader PCSC-lite 1.53 The problem is that the driver could not be loaded (into USB userspace). Maybe the libusb (compiled under Linux 2.6.25) is not complete compatible with L4Linux 2.6.22. Using Blockdevices such exernal Harddisks is possible, so USB support in general should be okay. Executing "lsusb" don't show ANY USB device. Only "lsusb -t" shows a correct result in which my cardreader is listed. Other parameter have the same output as "lsusb".

Hi, I'm just reading Dirk Vogt's thesis about 'USB for the L4 Environment' and I'd like to check out the corresponding code. I'm afraid it's not included in your svn-tree - is there any chance to obtain it? Kind regards Sven

So, Fiasco is able to detect the multicore platform and use the first core (CPU0) ? In that case, is it possible to launch the L4Linux in another specific core of the processor by adding kernel command (-nosmp, -isolcpus ) in l4linux26.cfg? > > > > > >Adam > -- > >Adam adam(a)os.inf.tu-dresden.de > > Lackorzynski http://os.inf.tu-dresden.de/~adam/ > > > > ------------------------------ > > _______________________________________________ > l4-hackers mailing list > l4-hackers(a)os.inf.tu-dresden.de > http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers > > > End of l4-hackers Digest, Vol 72, Issue 27 > ****************************************** >

ORe + L4Linux network performance
by Alexander Valitov 28 Apr '09

Hi All, Could anyone please tell me? 1. Did someone measure a L4Linux network performance when ORe is in use? Are there any report or paper with results? 2. What about 1 Gbit/s cards (e.g. Intel e1000)? Were they tested? 3. How badly is influence of other running L4Linux processes on network performance?

vbeset support for GRUB
by Neohtm 24 Apr '09

24 Apr '09

Hi, I'm able to compile L4 Fiasco + DOpE + L4Linux and test run on Qemu. But when i run it on the real machine, the GRUB seems don't support for modaddr and vbeset command. I got the GRUB-0.97 source from Adam's website and compile successfully. But what is the next step after this in order to boot directly on the current machine? I tried to copy directly the compiled files to /boot/grub but it didn't shows the menu.lst instead of that, i'm also not sure about how to tftpboot to another machine? any site or instructions on how to achieve this? Please advise. Thanks Regards, neohtm

Where to find Grub for Fiasco?
by Sid Yu 20 Apr '09

20 Apr '09

It seems that I can't use standard GNU Grub to boot fiasco directly, since there're several commands not recognized by standard Grub such as "modaddr", "vbeset" and etc. However, I couldn't find the enhanced grub tailored for Fiasco. Following the instructions on http://os.inf.tu-dresden.de/drops/download.html, I have tried to check out the "grub" module from SVN using "$ ./repomgr co grub", but it doesn't make sense. Could anybody tell me where to find the grub for fiasco? -- View this message in context: http://www.nabble.com/Where-to-find-Grub-for-Fiasco--tp23112750p23112750.ht… Sent from the L4 mailing list archive at Nabble.com.

In linking stage , it says that it cant find some refrences to param_set_bool' , 'vm_insert_page' , 'vmalloc_32_user' , 'dev_name', 'complete_all' . Should I add some static library in makefile which I have found under SRC directory of USBCAM. Please notice that it is not giving any error in compiliation stage of diffferent object files. It gives error only in linking stage of usbcam.o . Please help me . Thanks Tapas ...

IPC transfer message question.
by Suresh Iyer 16 Apr '09

16 Apr '09

I am working on some modifying IPC behaviour for an alternative scheduling mechanism based on temporal partioning. I had a question related to L4 embedded IPC transfer message part ( I dont know whether this could be an L4 generic question ). In the IPC implementation for l4 embedded , i see that the data is transferred only( ie transfer_messsge called ) only during a send phase of the code. Does this have to be the case ? In other words, lets assume A is sending to B and B is not ready to receive.. If we switch to B , and the code reaches Bs receive phase, cant B transfer the data from As utcb to Bs utcb by calling transfer_message of L4ka ? or do we have to switch back to A to make the transfer message happen ? The L4 embedded code seems to be doing this . Any reasons for this ? would really appreciate a prompt answer, Thanks so much !! suresh.

Hi, Thanks for your help. Usb mouse is working now!! .. I have gone throush USB CAM folder. Could you please tell me which file contains usb driver for your CPIA webcam. I have seen 1 folder named "contrib" under usbcam directory. I think that it contains lots of linux usb webcam drivers under directory "l4/pkg/usb/examples/usbcam/contrib/linux/drivers/media/video" . I didn't understand make files in every directory. Could you please explain compilation procedure without using make files. What is the use of contrib directory under usbcam folder? Please let us know which files are responisble for usb webcam device driver function. I am a beginner . Please help me.

NAPI and libdde_linux26_net
by Alexander Valitov 14 Apr '09

14 Apr '09

Hi, Does libdde_linux26_net support NAPI? >From the first glance it doesn't. Do you have plans about adding NAPI support? Some Linux network drivers don't have 'no NAPI' mode. So couldn't be used 'as is' in ORe. Situation may get worse in the future.

ORe and HW MAC assignment
by Alexander Valitov 13 Apr '09

13 Apr '09

Hi, For some reason ORe have only one global flag 'device_mac_available', not per each 'net_device'. So if you've got several NIC's and tries to open them all with 'ro_keep_device_mac' set (get HW MAC if possible): open("eth0") - will succeed open("eth1") - will fail (Virtual MAC returned) open("eth2") - will fail ...so on... Is it necessary requirement to have only one HW MAC been assigned?

Announcement: DDEUSB released
by Dirk Vogt 09 Apr '09

09 Apr '09

Hi L4-Hackers! We are glad to announce the release of DDEUSB, a USB driver framework for L4Env. It will be available in public SVN from now on under l4/pkg/usb. DDEUSB is a USB driver Framework for L4Env. It consists of the DDEUSB server "usbcore" and its clients. This package contains two sample clients. First, "usbcam" a USB camera viewer for dope and "usbhid" a USB human interface device driver, which forwards input events (from mouse and keyboard) to the L4Input injection proxy. More information on DDEUSB can be found in my thesis "USB for L4Env" [1]. Best regards, Dirk [1] http://os.inf.tu-dresden.de/papers_ps/vogt-beleg.pdf

Can anybody tell me how to build l4ata module found in TUDOS DEMO CD

Hi ALL, In TUDOS DEMO CD , we have seen a tutorial about DSweeper. http://demo.tudos.org/dsweeper_tutorial.html It demonstrates how to destroy all data in a particular hard disk partition. But I have no got any source code with the CD downloaded from http://demo.tudos.org/eng_download.html Then I have downloaded from svn repository by $ svn co -N http://svn.tudos.org/repos/tudos/trunk tudos $ cd tudos $ ./repomgr co all I have got all the modules and build them using cd l4 make O=/build_directory But I have not found some modules like bddf, l4ata, backdrop, dsweeper in "build_directory" or "l4/packages" directory. Among these packages, I think l4ata is in /tudos/l4/pkg/dde/fbsd/lib . But I cant build l4ata by running make in that directory. I have seen that it is possible to write in a partition in following DSweeper tutorial: http://demo.tudos.org/dsweeper_tutorial.html But I am not finding any API refrenece or source code of example to do it. I want to read/write using l4 in any filesystem.

Please also let us know the required menu.lst file to use this application . 1) Please also describe required menu.lst file to use dde, dde_linux26, dope, drop,loader together . 2) Could any body tell us what is the difference between dde and dde_linux26 application found in svn ? 3) Please also tell us how to use these to build an usb device driver. Thanks & Regards, TAPAS KUMAR KUNDU

Fiasco Kernel: Trap=03

Hi, In order to increase the Fiasco performance, I removed all debug-stuff from the kernel. But as soon as I remove the JDB, I receive a kernel trap on all starting apps: 2.00 IP=00103480 Trap=03 [Ret/Esc] 4.00 IP=00112bc0 Trap=03 [Ret/Esc] Do you know what might cause these traps? Attached is my fiasco.config and below some more output... *snip* Welcome to Fiasco(ia32)!

USB Keyboard and l4con
by Alexander Valitov 06 Apr '09

06 Apr '09

Hi, I've got the problem. l4con doesn't work with USB keyboard. It occurs with L4linux+l4con and even with simple txtmode con applications. "USB legacy support" is turned on. Here is how l4con complains: C.05:con | atkbd.c: Unknown key pressed (translated set 2, code 0x66 on is a0060/ C.05:con : serio0). C.05:con | atkbd.c: Use 'setkeycodes 66 <keycode>' to make it known. C.05:con | atkbd.c: Unknown key pressed (translated set 2, code 0x66 on is a0060/ How could it be solved? Best Regards, Alexander Valitov -- View this message in context: http://www.nabble.com/USB-Keyboard-and-l4con-tp22821747p22821747.html Sent from the L4 mailing list archive at Nabble.com.

l4ts_free_task()

05 Apr '09

Hi List, I have another question regarding L4Linux and IPC. Whenever I perform IPC-communication, I get the following debug output: l4lx| l4ts_free_task(): Could not return task. This message is repeated twice on every IPC-call. What is the cause of this and how do I get rid of this? ;) Thanks in advance!

Urgent help needed to port some drivers on Fiasco L4 µ-Kernel
by tapas kundu 03 Apr '09

03 Apr '09

Hi ALL, We are students of IIT Delhi. We are working on a project based on Fiasco L4 microkernel. We need to buid servers on L4 for ext2 filesystem support and usb web cam support. Could you please clear following doubts : 1) Does "fiasco l4 microkernel/ l4 env" provide support for ext2 filesystem or usb webcam ? 2) Does "fiasco l4 microkernel/ l4 env" provides Device Driver API library so that we can build driver for it ? 3) Do we need to build both usb driver and webcam driver in "fiasco l4 microkernel/ l4 env" to provide support for usb webcam ? 4) Does "fiasco l4 microkernel/ l4 env" provides l4 io driver for SATA or IDE harddisk ? Can we use that to build our ext2 filesystem support for it? Thansks & Regards Tapas Kumar Kundu

Questions about FLIPS
by Alexander Valitov 30 Mar '09

30 Mar '09

Hi, I've got some questions about FLIPS functionality. 1. Does flips contain internal routing mechanism? Can I get access to routing tables through NET_LINK socket interface? 2. Does flips contain netfilter or something like this? If yes, can I get access to it? 3. What about SNAT/IPmasquerading? Is it supported in some way? 4. Does flips support IPsec? Maybe another L4 package could provide such a support? AFAIK there was "Viaduct" and "nethub" projects. Seems that nethub is discontinued. I believe there should be some results. Does someone keep working in this direction?

L4 Server Dynamic Loading

while we could specify the initial servers on grub.conf so that they would run when the system reboots, I'm wondering how could I dynamically load L4 servers after that?

socket libc backend misses recvmsg()

Hi, It seems that file l4/pkg/l4vfs/lib/libc_backends/socket_io/socket.c misses recvmsg() function. There is send(), sendto(), sendmsg(), recv(), recvfrom(), but no recvmsg(). Maybe it's just oversight?

IPC problem with dice-3.3.0
by Marcel Selhorst 27 Mar '09

27 Mar '09

Hi l4-hackers, I am currently having some issues with dice-3.3: First of all, the dice-generated code differs in header- and client file, meaning that the header defines functions with int DICE_CV somefunction() while the outcoming c-file is int somefunction() This leads to compile errors due to conflicting declarations... But as soon as you remove DICE_CV, everything compiles fine. The second problem I have regards IPC-calls: I am using the latest otc-snapshot (2008-12-10 with l4linux-2.6.27) and have written a small IDL-interface as follows: dummy.idl: == interface dummy { void hello(void); } == The server (running under L4Linux) registers itself at the names-service as "dummy" and starts the server_loop... It implements the dummy_hello_component as follows: == void dummy_hello_component (CORBA_Object _dice_corba_obj, CORBA_Server_Environment *_dice_corba_env) { /* do nothing*/ printf("Hello\n"); } == Additionally, I have written 2 clients, one native L4 application and one based on L4Linux, which implement the client-stub as follows: == static l4_threadid_t threadId; static CORBA_Environment env; names_query_name("dummy", &threadId); LOG_printf("Dummy found with threadId: %x\n",threadId); dummy_hello_call(&threadId, &env); == The native client (started via bmodfs) receives a pagefault, cause it is trying to write?! to address 0: == dummytest| Dummy found with threadId: 11a0001 dummytest| L4RM: [PF] write at 0x00000000, ip 02000272, src 11.02 dummytest| [11.0] l4rm/lib/src/pagefault.c:81:__unknown_pf(): dummytest| unhandled page fault --PANIC, 'g' for exit------------------------------------IP: 02005755 [dummy.rm] (11.00) jdb: == And the L4Linux-client crashes with a segfault: == dummy_t[42]: segfault at 2 ip 08048312 sp bf4092ec error 6 in dummy_test[8048000+76000] == The strange thing is: If I compile the idl-file with dice-3.2.1, the dummy example works, BUT as soon as my interfaces get more complex, e.g., something like this: int write ([in] long start, [in] long offset, [in] long bytes_to_write, [in, size_is(write_len), max_is(MAX_PAGE_SIZE)] char *write_buffer, [out] long *write_len); IPC crashes with pagefaults / segfaults again even with dice-3.2.1... My Fiasco-config is attached. Do you have any ideas where the problem might be? Do I have to pay attention to specific configuration options, if the IPC-server is running in an L4Linux?

[BUGREPORT] DDE timer handling
by Andre Puschmann 27 Mar '09

27 Mar '09

Hi list, I am working on a port of an Ethernet-based fieldbus stack to TUDOS. The stack is a Linux kernel module so I am utilizing DDE as a wrapper for this. Things seem to work like this: the module creates a kernel thread which does the network polling in an endless loop. The loop basically looks like this: while (1) receive_data() process_data() send_data() schedule_func() Here, schedule_func() does the following: set_current_state(TASK_INTERRUPTIBLE); schedule_timeout(1); Which I interpret as something like wait for 10ms (assume HZ==100) or an event to occur and then restart the loop. schedule_timeout() creates a new timer with the specified timeout and calls plain schedule(). Ok, this works quite good up to an arbitrary point where the complete system stops working. Sometimes, the system runs 2min, sometimes 1h and sometimes 3h, so it varies a lot. After the stuck occurs, using jdb, I see the kernel_thread waiting for a message to be woken up. On the other hand, the timer_thread which has to throw this messages is in idle state. I am still a L4 beginner, especially in debugging its subsystems. However, for me that looks like we lost a timer event somewhere. I replaced schedule_timeout() with msleep(10) which omits the timer stuff and that works for me here for hours without any stuck. Before further tracking down this issue I want to make sure that you guys don't have any patch pending that fixes that problem, have u? Best regards, Andre

fnmatch() is absent in ulibc port
by Alexander Valitov 26 Mar '09

26 Mar '09

Hi, I'm porting some Linux application to L4Env using your ulibc port. The application uses fnmatch() function from libc. For some reason this function is absent in BUILD-DIR/lib/x86_586/libuc_c.a file, but at the same time BUILD-DIR/include/uclibc/fnmatch.h is present. So compilation completes without error, but linkage fails. Was it done intentionally? ./l4/pkg/uclibc/lib/uclibc/Makefile does not even try to compile ./l4/pkg/uclibc/lib/contrib/uclibc/libc/misc/fnmatch/fnmatch.c. See DIRS variable definition. If it was done intentionally. Why the header is in the way?

L4linux Installation Problem(Double Page Fault)

Right now I'm working on a project which utilizes Fiasco/L4Env/L4Linux environment, so I'm just trying to set it up on my workstation. Unfortunately, I have encountered some problems which bothered me for days. Could anybody help me out? Any help or suggestions would be appreciated, Thank you.

Problem with L4Linux ORe stub driver
by Alexander Valitov 24 Mar '09

24 Mar '09

Hi, I'm trying to run L4Linux with ORe. I can successfully run L4Linux without ORe and can run ORe without L4Linux (arping works). But when I try to run L4Linux with ORe, boot process hangs up after message from stub driver: eth0: Overwriting IRQ type for IRQ 10 with l4ore type! eth0: request_irq(10, ...) l4lx | l4x_ore_irq_startup l4lx | l4lx_thread_create: Created thread 10.0b (L4OreRcv) eth0: interface up. After some time a following message (with some additional info - see it in a boot log given at the end of letter) appears: BUG: soft lockup - CPU#0 stuck for 61s! [pump:92] I guess it caused by the ORe stub driver but it's only guess. What could it be? What could I try to do? Here is my 'L4Linux cfg file' and 'boot log': L4Linux cfg file: task "vmlinuz4" "earlyprintk=yes mem=64M load_ramdisk=1 ramdisk_size=16384 root=/dev/ram l4env_rd=drops.rd" all_sects_writable allow_vga allow_cli Boot log: Booting 'L4Linux-2.6 + l4con + ORE' kernel /boot/L4Linux/bootstrap [Multiboot-elf, <0x2d0000:0x700c:0x3e94>, shtab=0x2db118, entry=0x2d0000] modaddr 0x02000000 Setting module load address to 0x2000000 module /boot/L4Linux/main -nokdb -serial_esc -comspeed 115200 -comport 1 [Multiboot-module @ 0x2000000, 0x5d410 bytes] module /boot/L4Linux/sigma0 [Multiboot-module @ 0x205e000, 0x36f4a bytes] module /boot/L4Linux/roottask task modname "loader" allow_cli task modname "bmo dfs" attached 5 modules [Multiboot-module @ 0x2095000, 0x9cc3f bytes] module /boot/L4Linux/names [Multiboot-module @ 0x2132000, 0x415fd bytes] module /boot/L4Linux/log [Multiboot-module @ 0x2174000, 0x3e5c0 bytes] module /boot/L4Linux/l4io [Multiboot-module @ 0x21b3000, 0x26dd06 bytes] module /boot/L4Linux/events [Multiboot-module @ 0x2421000, 0x40c62 bytes] module /boot/L4Linux/dm_phys --isa=0x00800000 -v --events [Multiboot-module @ 0x2462000, 0x9b17d bytes] module /boot/L4Linux/simple_ts -t 300 [Multiboot-module @ 0x24fe000, 0x4d625 bytes] module /boot/L4Linux/rtc [Multiboot-module @ 0x254c000, 0x3023b bytes] module /boot/L4Linux/ore [Multiboot-module @ 0x257d000, 0x3af5c8 bytes] module /boot/L4Linux/l4con [Multiboot-module @ 0x292d000, 0x187b11 bytes] module /boot/L4Linux/bmodfs [Multiboot-module @ 0x2ab5000, 0xa629a bytes] module /boot/L4Linux/l4linux263.cfg [Multiboot-module @ 0x2b5c000, 0x98 bytes] module /boot/L4Linux/libloader.s.so [Multiboot-module @ 0x2b5d000, 0x9ceee bytes] module /boot/L4Linux/libld-l4.s.so [Multiboot-module @ 0x2bfa000, 0x78c39 bytes] module /boot/L4Linux/vmlinuz4 [Multiboot-module @ 0x2c73000, 0x369fcf bytes] module /boot/L4Linux/drops.rd [Multiboot-module @ 0x2fdd000, 0x1000000 bytes] module /boot/L4Linux/loader --fprov=BMODFS l4linux263.cfg [Multiboot-module @ 0x3fdd000, 0xdb766 bytes] vbeset 0x117 [VESA 3.0 info @ 0x40b9000, 0x2ff bytes] boot Welcome to Fiasco(ia32)!

Grub Question + some other information needed
by mcs082803＠cse.iitd.ernet.in 23 Mar '09

23 Mar '09

Hi List I know that a grub different from the standard is used. I downloaded the grub on Adam's site but have no idea how to get that diff file to work. There is a ReadMe called as grub-0.97-os.3.README that gives some info but I don't just get the fact that it is to boot from network. I am just booting from the hard disk using standard grub (with -modaddr option used with bootstrap), but now I need to use the vbeset command (and maybe others in future), so I really need that grub. I have done these $ wget ftp://alpha.gnu.org/gnu/grub/grub-0.97.tar.gz $ wget http://os.inf.tu-dresden.de/~adam/grub/0.97/grub-0.97-os.7.diff.gz $ tar xzf grub-0.97.tar.gz $ cd grub-0.97 $ zcat ../grub-0.97-os.7.diff.gz | patch -p0 so what i do next? just install this grub (using install) or something else? because the next steps in readme seem like specific for diskless booting from some network. and what version of adam's grub should I download (i used the grub-0.97-os.7.diff.gz because it seemed latest). some other things (unrelated to above) -- can i make programs that could write output to some file on hard disk. Is somewhere a reference manual that gives info about what datatypes and functions can i use in a general program i write, e.g. to do something equivalent of scanf,malloc,etc. Regards, Ashish

difficulties with Loader
by Alexander Valitov 23 Mar '09

23 Mar '09

Hi, During my play with 'run' application (./l4/pkg/loader/examples/run) I've discovered two issues. They both applies to the chain 'run'<->'loader'<->'simple_ts'. 1. First issue: I start 'con_demo1' application using 'run' utility 'l' command, then try to kill it. Kill process fails with following output (here F.02 is 'run' thread, 10.00 is 'con_demo1' task): A.00:simplets| task_kill(): Kill 10.00 from E.02 but owner is F.02 E.02:loader | l4ts_kill_task(): failed (dest=10.00 server=A.00, ret=-11, exc 0) E.02:loader | con_demo1,#10: Error -11 (not owner) killing task (ignored) It looks like inconsistency in loader's behavior. 'run' uses l4loader_app_open_call() and l4loader_app_kill_call() l4loader's methods to start and kill application, but l4loader_app_kill_call() invocation always fails as 'loader' explicitly set 'run' as owner: /* set client as owner so that client is able to kill that task */ if ((error = l4ts_owner(app->tid, app->owner))) { app_msg(app, "Error %d (%s) setting ownership", error, l4env_errstr(error)); return error; } But 'l4loader' implicitly passes itself as caller when he makes call to l4ts_kill_task() in app_cleanup_extern() function. So I think inconsistency is quite obvious. A straightforward solution here is just to remove l4ts_owner() invocation from l4loader's code. Do I miss something? 2. Second issue Scenario is the same as before: 'con_demo1' is started by 'run' and then killed by using run's 'kill' command. In this case: - 'run' calls l4loader_app_kill_call() - 'l4loader' calles app_cleanup_extern() - app_cleanup_extern() calles l4ts_kill_task(app->tid, 0) As a result simple_ts will not free allocated TaskNo for 'con_demo1' (use run's 'A' command for TS state after task has been killed). I think last argument for l4ts_kill_task() function is wrong. It should look like that: l4ts_kill_task(app->tid, L4TS_KILL_FREE) here is a path for the last issue: Index: app.c =================================================================== --- app.c (revision 439) +++ app.c (working copy) @@ -1488,7 +1488,7 @@ if (!l4_is_invalid_id(app->tid)) { killing = app->tid; - if ((error = l4ts_kill_task(app->tid, 0))) + if ((error = l4ts_kill_task(app->tid, L4TS_KILL_FREE))) app_msg(app, "Error %d (%s) killing task (ignored)", error, l4env_errstr(error)); else Any objections?

DEFAULT_RELOC and roottask
by Alexander Valitov 19 Mar '09

19 Mar '09

Hi, I try to run l4con examples with grub script given in ./l4/pkg/l4con/doc/menu.lst (slightly modified/updated). The menu.lst starts con_demo1, con_demo2 and con_demo3. Boot process gives me this error: #0d: loading "/boot/test/con_demo1" from [026ce000-0277262c] to [00800000-008250b5][00826000-0083d000] entry at 00068370 via trampoline page code symbols at [3a30e000-3a313000] (20kB), lines at [3a2fd000-3a30e000] (68kB) #0e: loading "/boot/test/con_demo2" from [02773000-02804e08] to [00800000-00815d11] Roottask: cannot load binary because address at 00800000 not free loaded module: [02773000-02804e08) /boot/test/con_demo2 overlaps with: [00800000-00826000) #0d con_demo1 I found that Makefile specifies DEFAULT_RELOC_x86 variable as: DEFAULT_RELOC_x86 = 0x00800000 As a result -Ttext=0x800000 option is added to 'ld' invocation options. I thought that is the root of problem and commented variable, but It didn't help. Build system started to use default DEFAULT_RELOC value 0x01000000 from ./l4/mk/binary.inc and roottask gives the same error with new 0x01000000 address. 1. I thought that DEFAULT_RELOC specifies virtual address not a physical one. Am I right? 2. If answer to my first question is 'yes'. Why in this case roottask relocates a code? It is strange as roottask operates with physical memory addresses. 3. When am I supposed to specify DEFAULT_RELOC variable? In which situation? 4. Why do we need the relocation performed by root task at all? Why can't we just use appropriate mapping to addresses where GRUB loaded ELF modules? Each server starts in its own virtual address space, so I think it's possible. Why was it done that way? What is the problem with described approach (without relocation)? 5. I've been playing around with L4Env,L4Linux and stuff for a while but have never faced with mentioned problem. Are there anything special about the way how con_demo1,2,3 are built? I mean Root task relocates another modules to the next free 4K aligned address but con_demo1,2,3 modules to some exact address. Why does it happened? 6. There is ./l4/pkg/l4con/examples/Makeconf file with link addresses specification. But according to "Building Infrastructure for DROPS (BID) Specification" only Makeconf.local file is included into generated Makefile from project directories. Why is it where?

Build DROPS on 64bit Host for 32bit Target
by Alexander Valitov 19 Mar '09

19 Mar '09

Hi, Is it possible to build DROPS on 64bit HOST OS for 32bit TARGET (architecture there Fiasco will be executed) if corresponding cross-compiler is already available? I tried but it looks like DICE ignores TARGET architecture and generates IPC code for HOST architecture (64 bit). It seems that there are no problems with Fiasco, L4Env and L4Linux.

Patch for DICE that fix issue with AMD64 host
by Alexander Valitov 19 Mar '09

19 Mar '09

Hi, I would like to submit path that fix problem when you use DICE to produce code for i32 on 64bit OS. Please see this thread for details: http://www.nabble.com/Build-DROPS-on-64bit-Host-for-32bit-Target-td22563295… The root of problem was that DICE determines some data type's size as sizeof(type). This is obviously wrong if DICE is a 64bit application and a code is generated for 32bit system. I would like to thank Roman I Khimov for spending his time for locating the issue and kindly providing us with the following patch.

Problem with Fiasco under QEMU
by Alexander Valitov 18 Mar '09

18 Mar '09

Hi, I've encountered problems under QEMU. Problems occur in many different configs but this is the simplest way to reproduce: Build Fiasco with default config, only "Handle and preserve segments" shall be turned on. Configure ORe for RTL-8139 NIC only and build L4Env. Build L4Linux with x86-ux_defconfig, only "ORe stub driver" shall be turned on. Boot with following QEMU command: qemu /dev/sdb -no-kqemu -serial telnet:localhost:5555,server NOTES: 1. I use USB flash stick but image file could be used as well with the same result. 2. You may pass option -net nic,model=rtl8139 but result will be the same Error log (in second case uKernel crashes): If you don't load ORe module you should see: l4lx | setup_l4env_memory: Forcing superpages for main memory DMphys | [9.0] dm_phys/server/src/open.c:98:__create_ds(): DMphys | DMphys: memory allocation size 65536KB pool 0 failed! l4lx | [F.4] dm_mem/lib/clientlib/src/open.c:80:l4dm_mem_open(): l4lx | libdm_mem: open dataspace at 9.00 failed (ret -2, exc 0) l4lx | setup_l4env_memory: Can't get main memory of 64MB: out of memory(-2)! l4lx | Main thread running, waiting...
