Some questions
by fabs0028＠free.fr 07 Jul '05

07 Jul '05

Hello, I first wanted to signal about a little problem i found : when i launch an application i did for l4 with the loader it works fine but after its end i want to launch a legacy linux application and i get the message KERNEL: Security violation: Not pager of 36. Maybe i forgot something to close my program but i don't know what or maybe it is something else. I also wondered if it was possible to build a standard linux kernel from the l4linux sources ? I think so but i'm not sure. And for a last question i'd like to know if there's a way to share devices such as for example hard drives between l4 and the l4linux server. I saw dde but i don't know if it is still up with the 2.6 portage and i haven't found a lot of doc about it except the manual. Thanx a lot for your help. Fabien Chaillou

using patched gcc toolchain
by Emanuel Thomas 07 Jul '05

07 Jul '05

Hello, I want to use a patched gcc toolchain, but i'm going to have problems. Is there a global configuration file where I can (easily) which gcc (and other tools) should be used? Even "make confg" seems to use the standard gcc. Where can I change that? Emanuel

All, With this setup, what's the best way to reboot the system remotely (e.g. via ssh)? Rebooting the L4Linux server appears to exit all linux related activities and terminate their L4 tasks but the system does not reboot. Thanks! -Julian > Hi, > > I got it working.

l4lx: l4FB via con and dope
by Andrew Davenport 06 Jul '05

06 Jul '05

Hi, I am trying to setup a lean l4linux-2.6 with a local text console, without dope or con. I got it printing out the console an login prompt but it ignores input from the keyboard. I have one of those multiplexing devices - that switches the keyboard, mouse and monitor from one computer to the other -- i have a computer for compiling and one for testing. This may be a reason why it ignores the keyboard.... Thanks, andrew

task not cleared properly
by Bert van Leeuwen 30 Jun '05

30 Jun '05

After my main function has exited, the task still seems to live. On the serial debug console I see: myapp | Main function exit with code 0 but pressing N at the cmd prompt console shows: 1E.00 myapp.rm 1E.01 myapp.sem 1E.02 myapp.main and every time I run my app another instance appears... Is there anything I am supposed to do to make the task go away properly? I am running simple_ts and events, and my app is a l4env_freebsd app compiled in DROPS and running in the fiasco kernel. Let me know if I need to supply further information.

relocated address
by Bert van Leeuwen 30 Jun '05

30 Jun '05

Is there a way to get a program's relocated address? I think I need this to make my program work correctly when run from loader via tftp... I access a PCI device, the code at one point calls virt_to_bus, which uses an extern unsigned int offset which is 0, but there is a comment saying that the offset should be set to the program's relocated address instead of 0... Running my program from grub works just fine, but not from loader, presumably because of this. The program itself "works" from loader, but not the PCI interfacing, so I'm sure its got something to do with relocation. Any help would be greatly appreciated.

Memory management
by Julian Stecklina 29 Jun '05

29 Jun '05

Hello, let's say in my rootserver I need a contiguous block of memory 1 MB in size. I would request this memory from Sigma0 via L4_Sigma0_GetAny and get a single Flexpage of this size. In order to implement a fine-grained write-barrier on parts of this memory block, I need to make individual pages of this block read-only. As I understand it, the privileged system call MemoryControl provides this functionality, but: a) it is privileged, but all my servers would need this functionality. How is this efficiently accomplished? b) MemoryControl seems to operate on whole fpages only. How do I split a flexpage?

L4Linux console using CPU
by Bert van Leeuwen 24 Jun '05

24 Jun '05

Hi, Does anybody perhaps know why a DROPS virtual console focused on a L4Linux virtual console uses up CPU time? Is this "normal" behaviour? My DROPS console shows +- 25% CPU usage if the DROPS virtual console is focused on the L4Linux terminal, +- 1% if the DROPS virtual console is focused on something else (e.g. run console). From what I can tell, the thread running the L4Linux virtual console is at priority 0xff, but the main L4Linux task appears to be at default priority 0x10... Is this correct? Thanks in advance, Bert

Hi all, I've "extracted" the E1000 driver code from the TFTP server to get some packet data directly into L4. I've noticed that if I load this task with the loader then the TX part sends garbage. I then added (for fun) the attribute (section "STACK") to the buffer from which the packet is send and now it works. Can anybody explain this to me! Send a link to some use full doc? Thanks Leon

Announcing Magpie, an L4 interface generator
by Nicholas FitzRoy-Dale 19 Jun '05

19 Jun '05

Hi everyone, I'm pleased to announce the first public release of the Magpie interface generator. Magpie was written at the University of NSW over the course of the last six months to support several operating system projects. It was inspired by, and owes a large debt to, the de facto interface generator for L4, IDL4. Magpie's advantages over IDL4, are in its use of templates for output, allowing rapid changes to output modes and easy sharing of output code, and its support for the ARM architecture. On the flip side, Magpie does not currently support DCE IDL, long IPC, or optimised stub support for the ia32 architecture. New output modes, such as component orientation and C++ support, are in development and planned for a future release. Magpie is currently experimental software, under active development. If you use it, I would be very interested to hear any reports, both positive and negative. Bug reports are, of course, particularly appreciated. Magpie can be downloaded from here: http://www.disy.cse.unsw.edu.au/Software/Magpie/ Nicholas FitzRoy-Dale DiSy group, UNSW

Rights Amplification
by Marcus Brinkmann 16 Jun '05

16 Jun '05

Hi, Last week when Neal was visiting Dresden, he explained how rights amplification (i.e. passing capabilities as arguments to capability object invocation) doesn't work with the current L4 capability framework. The specific example he gave was that of a memory server which provides so-called memory containers and the ability to copy memory between memory containers using something like: container_copy (A, a_start, B, b_start, length) where A and B are capabilities/end points presumably to the memory containers. To perform a container_copy, the client would send an IPC to the capability/end point A and map B to the server. The server is told the id of the receive end of the end point A and thus can easily find the server object associated with A, however, it has no way to derive the receive id of B (even though it serves B) and thus has no way to find the associated server object. The following discussion presents the problem more generally, shows that the above is a special case of a larger problem and presents a solution which minimally modifies the current L4 capability proposal. The main purpose of the suggested solution is to further illustrate the semantics that we consider necessary, and to start a discussion. Rights Amplification and future L4 designs (Marcus Brinkmann, Neal Walfield) ============================================================================ Not much can be said about a capability system without first determining how capabilities are represented. The current proposals assume that server objects will be represented by communication end points (more precisely, by the receive end). The send sides of the end points then assume the role of the capability. This is not the only solution. Other primary (kernel) objects following the map/grant/unmap semantics could be used to represent objects and capabilities. Within this framework, the only directly supported operations on such capabilities are map, grant, unmap and IPC. The map operation can be used to delegate the capability, grant can be used to move the capability and unmap to revoke it. The IPC operation allows clients to send messages to an object, for example, to invoke operations on the object. The server can identify the object only when it receives a message on it: on message receipt, the receive side of the end point is presented to the receiving thread. There exists (by assumption) a one-to-one relationship in the server between receive sides of end points and server objects. Thus, given the receive end point, the server can determine to which object any given message was sent. (Note that if you do not use communication end points as object identifiers via a 1:1 relationship, determining to which object a message should go is an open question whose answer depends on how objects identifiers are represented in the first place.) The problem for us is that identifying the object only in the server and only when a message is sent to the object is not sufficient to implement the system we have in mind. In general, we need to be able to know if two capabilities (that is, mappings), are, from a certain perspective, "identical". Identical in this context means that one of the mappings is an ancestor of the other mapping, i.e. that both are associated with the same communcation end point. For our purposes, we don't need to compare _any_ two mappings to the same communication end point; we only need to be able to compare two mappings in the case that one is an ancestor of the other. The following examples will make it clearer. Usage scenario 1: Operations on multiple objects. Consider a server providing multiple objects of the same or different types and operations which require access to more than one of the objects at the same time, i.e. right amplification. The classic example is that of the can and the can opener: an operation such as "open_can (can_opener_t opener, can_t can);" or equivalently "open_can (can_t can, can_opener_t opener);" can only be invoked on either of the two objects but requires capabilities to both. The second object is passed as an argument in the RPC. The server receives the message on one of the two objects which it can readily identify but is now in the peculiar situation of needing to identify the other object. Within the proposed framework, the only low-level mechanism that seems feasible at all here is that the caller _maps_ the second object to the server so as to prove that it has the capability in question. This proof is without meaning if the server cannot establish that this mapped capability is indeed associated with an object it provides; the server must be able to lookup the object based on the mapping from the caller. Usage scenario 2: Reference counting. Modern microkernel based operating systems usually ask for explicit creation and destruction of resources, and rightly so. But at least for legacy support it must be possible to implement reference counting on top of them. Because references must be deallocated automatically on task death, the support for this must be integrated---at least to some extent---into the trusted computing base. Within the initial assumptions, a simple design for a reference counting server readily suggests itself: a reference counting server positions itself---mapping-wise---between a server and its clients. The servers map capabilities to the reference counter which in turn maps them to clients doing the necessary accounting along the way. There are a number of protocols which can be used to copy references from one task to another, etc. The following situation arises when copying a reference from a client, A, to a second client, B: A server, S, has mapped a capability (to a server object) to the reference counter C which has in turn mapped the capability to A. A then maps the capability to B thereby delegating it. B now wants to acquire its own reference and mapping from the reference counter in order to become independent of A. Situation: S -> C -> (1 reference) A -> B Goal: /-> (1 reference) A S-> C \-> (1 reference) B So, B makes an RPC to C: insert_reference (reference_space_t space, cap_t cap, cap_t *new_cap); (The reference space is an object provided by the reference counter and is a name space for all the capabilities to which B has references.) What is important here is that this operation takes a capability as an argument. In this way, B proves that it has access to the capability it got from A. The reference counter will reply with a new mapping that B can use which is independent of the mapping that it got from A - if B then unmaps the mapping it got from A, the situation is symmetrical and the goal accomplished. Shifting perspective from B to the reference counter, the reference counter is in a peculiar position: it is _not_ the server providing the capability CAP. Also, it didn't give a mapping for the capability to client B previously. So it is in a totally different position than the can opener server above: the reference counter sees only send sides, not receive sides, of the communication end points for which it manages references and furthermore it receives capabilities as arguments from tasks to which it didn't previously give mappings. However, there is still some structure left: the reference counter is a mapper of the capability CAP itself: it has a mapping of this capability which it got directly from the server. In addition, the mapping CAP is derived from this mapping in the reference counter itself via A. This is what we want to exploit: we want a way for the reference counter to find the mapping it got from the server for this object based on the mapping it got from B for the same object. The solution: Finding a solution to usage scenario 1 is not too difficult. One approach is protected payloads (a data word chosen by the server) which can be associated with the receive side of a communication end point and which can be read out based on the send side (the mapping, aka capability) if you are sufficiently privileged (i.e., if the receive side resides in the same address space). The protected payload can be set to an internal OID. This solution is inadequate for the second usage scenario: the thread doing the lookup (in the reference counter) did not create the communication end point and thus had no say in the protected payload. Moreover, it shouldn't be able to read it out even if there was one. So, the protected payload idea doesn't seem sufficient. There seems to be a tangible solution though: if there was a system call which allowed the caller to check if a mapping was derived from another mapping in the same address space, then we can use that to "unroll" mapping loops like the one in the first scenario, i.e. Server -> Client -> Server, or in the second, i.e. Server -> Reference Counter -> Client A -> Client B -> Reference Counter. More specifically: Each mapping is identified in the mapper's address space via a virtual address (or index, or slot number, ...). Then there could be a kernel system call vaddr_t map_lookup (vaddr_t addr); which walks up the mapping tree, starting at the mapping entry for ADDR and going to the parent of the current node in each iteration until a mapping in the same address space is encountered. The vaddr of this mapping is returned. Solution in usage scenario 1: Say the send side of the communication point created in the server for the object is located at the vaddr 10. The server records this information in some sort of table. Then the capability is mapped to the client. The client maps it back into the server as part of an RPC. This mapping from the client is installed into the server at vaddr 67. Now the server does: map_lookup (67) -> 10 The map_lookup in the kernel starts from the mapping the server has to the client. It then goes to the parent of that mapping which is the mapping B has from the server. B has a different address space from the server, so the kernel doesn't stop there and continues to the next parent. The next parent is the mapping the server has from the kernel (the communication end point). As address spaces match, the vaddr of this mapping, 10, is returned. The server can then look up the object data for the object associated with the vaddr 10. Solution in usage scenario 2: The server creates a communication end point and maps it to the reference counter which receives it, at say, vaddr 23. The reference counter writes in a table that vaddr 23 corresponds to this server's capability. Now A gets a mapping, delegates it to B, which in turn delegates it to the reference counter which receives it at, for example, vaddr 127. The reference counter does: map_lookup (127) -> 23 The map_lookup operation in the kernel starts with the mapping the reference counter has from the client B. It then walks up the tree first finding the mapping client B has from A, then the mapping client A has from the reference counter and eventually the mapping the reference counter has from the server. The reference counter address space is found and thus the vaddr of this mapping from the server is returned to the reference counter. The reference counter can then record a reference and create a mapping from the mapping "23" to the client B thus creating a symmetrical situation between client B and A. Conclusion ---------- The operation map_lookup achieves our goal of being able to implement the desired functionality. Note that it does not require the kernel to search the whole mapping tree: the tree is only walked from the current node up until the root; it is never walked down or sideways. This means that, for example, if the reference counter has multiple mappings from the server for the same communication point, it will see them all as being distinct (at least it can not establish the identity). It also means that if B gets a direct mapping from the server without going through the reference counter, then the reference counter will not be able to identify this capability as belonging to the same communication point as the mapping it already has. All of these limitations are perfectly acceptable and indeed beneficial. We don't want global identification; we just want to be able to detect mappings _back_ to us which somehow originated from us. I said this should be a system call but in fact that is an implementation detail. It may just as well be done via some other mechanism, for example, in transit during an IPC, if requested. That would actually potentially help. It's unfortunate that the tree has to be walked. Information that is associated strictly with the receiving side ("protected payloads" above) is faster to lookup and has a fixed cost, while walking a tree to the root grows with the depth of the tree. For a negative reply, the whole depth of the tree up to the root has to be walked. In common usage scenarios, however, the tree will not be very deep. I am no expert on mapping databases, so maybe playing around with the data structures can further optimize this path (for example, keeping linked lists per address space in the mapping tree would allow fast lookup of anchestors within the same address space, but my feeling is that maintaining such lists would be more expensive than doing the lookup when it is needed only). There may be security implications in revealing mapping "identities" at all. Maybe this feature needs to be restricted for confined tasks. However, some sort of rights amplification is essential and it is OK to ask for the cooperation of all tasks involved in determining the identity. If for example client A in the reference counter example can deny the map_lookup through its branch of the mapping tree then the reference counter will simply deny its service. This is perfectly acceptable to me; the important thing is that it must not be possible to trick some other task in believing an identity that doesn't exist: to hide identities is fine.

Still some boot problem

thanx for the answers. As you said, i forgot the vga in linux. I added the l4ser with the vga so now i got all the boot messages. For the panic, it was about my filesysten that the kernel wasn't able to mount so now it works. But now i got a warning saying that he can't open a terminal and after i go blind. Correct me if i'm wrong but i do think i need to use either dope or con or have i once more forgotten a thing in the kernel ?. One more question ... will X runs as if i was on a legacy linux ? (i think so but i'm not sure). Thanx a lot once more. Fabien Chaillou

It seems that the linux server has gone in l4x_blink and sleeps forever but i can't find out where it come from (Is it possible to follow the execution with jdb ?) Thanx a lot for your help.

Hi again, I need to load shared objects in my application. I've got .so loading working in a loader-mode app, but my app uses the l4env_freebsd mode so I cannot link against libloader.s.so. I've tried to link against libloaderif.a, but the l4loader_attach_relocateable() function is only available in libloader.s.so. Any help would be appreciated, Derick

questions on L4Env and libraries for development on pistachio
by Jayesh Salvi 10 Jun '05

10 Jun '05

I am looking for libraries to do coding on pistachio. As I understand L4Env gives a bunch of libraries - memory management libraries (dm_phys,...), l4io, etc. Could someone answer these questions: 1. From L4Env's docs I see it being used only with fiasco source code. Haven't come across any project that uses L4Env with pistachio. Any dependencies that I don't know of? If not are there any examples? 2. I want libraries for some basic functions - malloc, free, printf, etc. L4Env needs oskit, l4linux2.2 and fiasco L4 kernel. Aren't there any lightweight ways of getting such libraries for L4? Can parts of L4Env used seperately in pistachio tree? 3. I came across libCLight library which is the light implementation of libc. I could get it compiled in my pistachio tree, as done in IoL4 project. Can anyone compare using malloc in libCLight and using DMPhys of L4Env? Hope these questions are not that naive. Thanks in advance. -- Jayesh

Hello, i'm trying to create a l4linux system based on l4linux 2.6 and fiasco. i builded l4linux with l4env and fiasco from scratch with no problem but when i wanted to launch it i had problems with the grub version (gnu grub 0.95). I took your grub version as i was advised but i can't build it i have some problems, mainly with a reference to memcpy in some files in the stage2 directory, but what's weird is that there's no references to that fonction in the concerned files.

gettimeofday(2) and time(2)
by Derick Swanepoel 09 Jun '05

Hi all, I would like to get the current time as reported by gettimeofday(2) and time(2). However, neither of these functions seem to work in L4. gettimeofday() fills in the timeval struct with random values and time() always returns -1. What is the correct way to get the time in seconds since the Epoch in L4? Thanks in advance, Derick

TFTP server and E1000 problem
by Leon Brits 04 Jun '05

04 Jun '05

Hi all, I've just received an Intel E1000(82545GM) NIC to make work with the TFTP server. The problem is that it does not seem to receive packets when connected to a GigE switch. It does work with a Fast Ethernet switch. The switches are from the same manufacturer. I do see the initial DHCP/BOOTP message send out, so I added some debug code to the rx-polling routine and it does not ever receive anything. I've looked on the Etherboot-project's mailing list and found some comments to a similar error back in 2002 but no mention of a reason or a fix. Any suggestions? Thanks Leon

Debugging an L4 task
by Derick Swanepoel 02 Jun '05

02 Jun '05

Hi, I am trying to debug an L4 task that double pagefaults before reaching the main function. How should one use the debugger to run a task so it can be debugged without having to break into the debugger later? The backtrace doesn't seem very useful because it looks like a stack overflow due to infinite recursion.

IPCs
by Andrew Davenport 02 Jun '05

02 Jun '05

Hello, I am trying to make a simple IPC logger in L4 (by modifying the kernel). I want to eventually log src, dest, and contents of the message. Where would be most effective place in the l4 kernel to do this, and how should I go about getting the message contents -- eg registers, flex pages or strings ? Thanks, Andrew -- Andrew Winter Davenport Georgia Institute of Technology College of Computing www.prism.gatech.edu/~gtg259m

Hi all, I am adding a bit of extra code to the TFTP server and I found that if I malloc() memory that I get the error: ../com/register.c:78: failed assertion `global_registry' I've added the following line... l4_ssize_t l4libc_heapsize = 4*1024; ...to the main file but I still get the error. Any suggestions! Thanks Leon

Issues on L4linux
by Tiago Jorge 30 May '05

30 May '05

hello... I've been running l4linux in l4env mode for some time, but some errors never ceased to exist. The first error consists on page faulting. The error consists on the dm_phys saying it page faulted correctly, but the task i was running blocks... to what values must or wich commands sould i use in order to increase the memory so that i can proceed with the tasks? The other error happens when i try to reboot. When i halt the system, no problem arises. bue when i try to reboot, the systems always pagefaults... what's the problem with that? thanks for the help Tiago

running C++ function as THREADCONTROL thread
by Jayesh Salvi 25 May '05

25 May '05

Hi, I looked at the pingpong code and found how a thread is created and activated using THREADCONTROL system call. It uses C function pointers and typecasts them to L4_Word_t which are then passed to threadcontrol system call to run this function as thread. I want to use a C++ function as the thread. But C++ member function pointer seem not to be as simple as C function pointers. Their size changes as well, with the compiler or compiler-options, because of inheritance. Is their any example code that does this? Thanks. -- Jayesh

Porting C++ apps to L4
by Derick Swanepoel 24 May '05

24 May '05

Hi, I'm busy porting a C++ application to L4. From various comments on the mailing list I know that I cannot make use of exceptions and RTTI, but unfortunately the program links against a library that makes heavy use of both. What should I do? Is there any documentation or guidelines on porting C++ apps to L4? Thanks, Derick

ANNOUNCE: Pre-virtualization project
by Joshua LeVasseur 20 May '05

20 May '05

The L4Ka team is pleased to announce the release of a new approach to building virtual machines, which we call pre-virtualization. Pre- virtualization is a technique to automate para-virtualization, and is thus a more trustworthy alternative to L4Linux, and yet with the same performance that L4Linux has always achieved on the L4Ka microkernels. Since the virtualization is automated, the final binary (whether Linux 2.6, Linux 2.4, FreeBSD, etc.) can execute on raw hardware, and on a variety of hypervisors. At load time, the binary's virtualization-sensitive instructions are rewritten, and the OS is dynamically linked against an architectural emulation layer. The project has been co-developed with UNSW/NICTA. The project web page is located at: http://l4ka.org/projects/virtualization/afterburn/ The current release supports the L4Ka::Pistachio microkernel and the Xen hypervisor, on x86 hardware. We currently release support only for Linux 2.6 as a guest OS. Other operating systems are under test. This project obsoletes our prior L4Ka L4Linux work. We thus stop support for our L4Linux-2.4 project, and will not publicly release our L4Linux 2.6 project. Enjoy, The L4Ka Development Team

Reading and writing to files in DROPS

19 May '05

Hi, I'm still trying to write to a file in DROPS. What is the best way to do so? When trying to use the OSKIT support (at least I think that I use it...) it doesn't work, maybe I'm thinking too straightforward, but my code looks simply this way: --------------------------------------------------------------------- #include <stdio.h> char LOG_tag[9]="tso_test"; int main(int argc, const char**argv){ FILE *handle; int i; handle = fopen("/tmp/check","w+"); printf("before fileprinting\n"); fprintf(handle,"Just a writing to file test."); printf("after fileprinting\n"); fclose(handle); printf("after closing\n"); return 0; } -------------------------------------------------------------------- My Makefile (compiling without error or warning): -------------------------------------------------------------------- PKGDIR ?= ../.. L4DIR ?= $(PKGDIR)/../.. TARGET = tso_test DEFAULT_RELOC = 0x02000000 MODE = l4env SRC_C = tso_test.c LOGTAG = $(addprefix ",$(addsuffix ",$(TARGET))) include $(L4DIR)/mk/prog.mk -------------------------------------------------------------------- Finally my config: -------------------------------------------------------------------- title vmware tso_test root (hd0,1) kernel /drops/drops/bin/x86_586/l4v2/rmgr -sigma0 module /drops/l4/kernel/fiasco/build/main -nokdb -nowait -serial -serial_esc module /drops/drops/bin/x86_586/l4v2/sigma0 modaddr 0x02000000 module /drops/drops/bin/x86_586/l4v2/names module /drops/drops/bin/x86_586/l4v2/log module /drops/drops/bin/x86_586/l4v2/dm_phys module /drops/drops/bin/x86_586/l4v2/simple_ts module /drops/drops/bin/x86_586/l4v2/tso_test -------------------------------------------------------------------- But the error message: -------------------------------------------------------------------- names | Fiasco detected, registering thread names at kernel tso_test| OSKit support: using 4096KB at 0x00180000 as heap tso_test| fs_init: WARNING: No Filesystem tso_test| before fileprinting tso_test| Just a writing to file test.after fileprinting tso_test| L4RM: [PF] read at 0x000000c, eip 0200e54b, src 9.02 tso_test| [9.0] l4rm/lib/src/pagefault.c:78:__unknown_pf(): tso_test| unhandled page fault --PANIC--------------------------------------------------EIP:02004403 (9.00) jdb: -------------------------------------------------------------------- Of course, I can see that fs_init says about "No Filesystem". Is it because I'm using reiserfs? Would it work with ext2? Or is there a better way writing to a file in DROPS? Maybe some L4-specific functions? Regards, Rene

Building binaries for L4Linux with IPC
by Tiago Jorge 18 May '05

hello... I am trying now to do IPC to my server from L4Linux. I'm not doing a Lib. I'm picking up the client code generated from dice, build encapsulation code and i'm trying to use it in a simple program.

Killing L4Linux
by gjoel123＠fastmail.fm 17 May '05

17 May '05

Hi How does one kill L4linux from the DROPS console using the loader program? This is what I am currently doing: 1:I type 'n' at the DROPS console to get task ID's and names. This is what I get: . . F.02 LOADER 12.03 Linux server . . 2. I type 'k' and then '12', and I get: 'Error -11 (not owner) killing task #12'. Any ideas? The aim is ultimately to correctly halt/reboot l4linux from l4linux's own shutdown code. Regards Gordon -- gjoel123(a)fastmail.fm

10 May '05

Hi all, My Kernel Module seem to be working fine for most of the time. But I get an intermittent error where the Kernel crashes with the following error: <snip> Scheduling in interrupt KERNEL: 12.9 (tcb=c0484800) killed: Unhandled trap <snip> The Kernel module does not control any interrupts and at this point-in-time is pure virtual. Any ideas why or how to debugging this error is appreciated? Thanks Leon

Flips tracking of IPC
by Tiago Jorge 10 May '05

10 May '05

hello... I'm having a problem with the FLIPS server. I'm doing some transmission in TCP and i seems that the call from the client to the FLIPS server doesn't arrive. I've putten some printfs along the way in l4vfs_net_io_send_call and he does the call the IPC function... but i've putten also some debug message in l4vfs_net_io_send_component and it doesn't print out... so something is dying around here and i don't know where...:( My questions are... in the FLIPS/L4vfs net_io server side where should i put the debug to see if the call has arrived? (i've tried in net_io-server.c and nothing is shown) i've sent something earlier trought that socket... i mean... it only dies when i try to send something the second time... am i missing something (the socket its the same it stays connected)? is there any problem with FLIPS that prevents me from sending something from a socket that is blocked in a recv in another thread (should't be because TCP is bi-directional)? thanks in advance Tiago

RT issues
by Rene Wittmann 02 May '05

02 May '05

Hi, As I'm trying to implement a real-time application in DROPS, I still have some questions on this topic. Maybe there's someone who can answer them because I didn't find it described it the documentation... 1. The timer granularity seems to be set to 976 microsec. Is there a special background for using this number or can I set it down (maybe even to 10 microsec, which what be a good time resolution for my task)? How can I set it? Or would it be stupid to set it to such a tiny value? 2. When looking at the rt_sched example in the hello-package: the main-thread has a preempter-thread for recognizing timeslice overrun and deadline misses. When does this preempter-thread recognize a TS overrun or a deadline miss? Right after this event (so within the next time resolution) or after the main-thread says that is has finished it's work (meaning after a call to "l4_rt_next_reservation")? 3. How can the preempter-thread tell the main-thread to stop it's work in case of a timeslice overrun or even a deadline miss? 4. Does the system allow a thread's scheduling like this: period-length = 976 microsec, timeslice_mand = 9760 microsec, timeslice_opt = 9760 microsec (which would mean that the system had to reserve timeslices that don't fit into one period...) OR period-length = 9760 microsec, timeslice_mand = 4380 microsec, timeslice_opt = 4380 microsec (which would mean that the system had to reserve all resources for this thread..) (what would happen if another thread comes with a period_length of also 9760 microsec and a timeslice_mand = 6000 microsec? What would be the system's behaviour?) ===================================================================== Other thing: File system support: 1. which filesystems are supported (reiserfs?)? 2. Is there a way to have RT access to disk and accessing files this way? If so, how? Thanks, Rene

L4 IPC doubt
by Tiago Jorge 02 May '05

02 May '05

hello to you all. Let me describe my cenario... I have my L4 server that receives ipc calls. The code was generated from DICE. And i have a lib and i've implemented a client that uses that lib. My L4 server also uses ipc to comunicate with other servers, mainly with flips that also uses IPC. that problem is the following: My client makes an IPC call and blocks waiting for the answer from my server... while processing that answer, my server has to comunicate with flips using IPC. The problem is here... my server blocks in the ipc_send when calling flips, but when i remove the call from the client it works fine, meaning that the client is not blocked waiting for ipc to return. My questions are... why can't i do IPC while another one that has nothing to do with my server is blocked? there can be only one ipc call in the whole system at a time? they all must be sequential? thanks in advance Tiago

L4linux kernel module and IPC problem
by Leon Brits 29 Apr '05

29 Apr '05

Hi all, I've created some test code in a L4 Task, L4Linux App and L4Linux Kernel (2.4.28) module that communicates using short IPC messages. It works fine except that it seems that I can not send an IPC message to the L4Linux App from the Kernel Module (reverse is fine). l4_ipc_send() does not report any errors, but the App does not receive anything and the register values contains some 'random' values. Any suggestions for the reason? Suggestions as to how to debug this problem is appreciated! Thanks Leon

boot : C++ App on fiasco kernel.
by 노학종 13 Apr '05

13 Apr '05

Hi, hackers. I downloaded the latest cvs version that is everything all including fiasco, l4env, libstdc++, ostkit, ostkit10... etc. And I completed compile all without some package where /l4/pkg/... (l4vfs, nethub, proxygon, verner) I tested a sample binary that is hello_cxx where in /l4/bin/x86_585 directory. My grub menu(menu.lst) contains: title Test_fiasco_kernel kernel /boot/fiasco/rmgr -sigma0 modadder 0x02000000 module /boot/fiasco/main -noserial -nowait -nokdb module /boot/fiasco/sigma0 module /boot/fiasco/hello_cxx following, boot error messages: *hello : [5.0] l4rm/lib/src/config.c : 104 : l4rm_get_dsm(); *hello : l4RM:no dataspace manager found!! In /l4/pkg/hello_cxx/README, you recommend that use Symbols, buffermgr, simple_dm binary into menu.lst to using C++ code together with L4 environment. But I can't find out that binary files. So I tested using above menu.lst. 1) Could somebody help me about problems above? *************************************** General questions; 2) I want to that My APP Program(e.g. sample_cxx) build using C++ is execute on the fiasco kernel only without L4linux(kernel) Is it enable? 3) If enable, Please somebody give me a instrucion to build, and a sample grub's menu.lst to execute a sample_cxx after booting with fiasco kernel, in lastest cvs version. Noh, H.J.

Kernel Module Pointers for L4Linux on Fiasco
by Julian Grizzard 11 Apr '05

11 Apr '05

Anyone have any pointers on using kernel modules with L4Linux? Here's the setup: i386 L4 Fiasco V.2 L4Linux third party kernel modules We've been playing with various modules trying to get them to work with the L4Linux kernel. Some modules compile fine against the L4Linux source; others give warnings. Further, some load fine but do not work properly; others complain about missing symbols. It is conceivable that we have non-L4Linux related issues but wanted to check and see if there is anything special to know about building modules for L4Linux? Specifically, what are possible reasons that a kernel module would work on a stock i386 arch Linux kernel but not work on the same version L4 arch Linux kernel? Thanks! -Julian

Various things on log_net package
by Rene Wittmann 11 Apr '05

11 Apr '05

Hi, While trying to get the log server working for logging to network, I found some problems/bugs... And here is my report: L4DIR/pkg/log_net/server/src/tcpip.c: l.96 : in #define INITDRV(drv) the called function can give an error, but this error is just ignored (fct. init_ethernet always returns 0) l.264: (closing etherdev on error) if you select a wrong driver in init_ethernet, the system boot will fail with strange output over and over again (maybe just logging to normal console and go on booting is more desired??) L4DIR/pkg/log/server/src/logserver.c l.45: initializing buffer for net output if the buffer size is not given explicitly as command line switch the later buffer size is 0(!! not 4096 as expected). Therefore the logging to the network will not work. In order to prevent this you should put some lines right after parsing command line parameters in main(), e.g.: // if flushing to net && no buffer_size specified, use an initial value if (flush_to_net && !buffer_size){ buffer_size = 4096; } (or you should document it somewhere) BTW: to use the correct driver in init_ethernet for vmware, you should use "vlance" as network setting in vmware and "INITDRV(lance)" in init_ethernet, the drivers for 3com cards are not called 3c??? as I expected but can be used with "INITDRV(etherlink<??>)" with <??>="","2","3","16","plus" or "INITDRV(vortex)". In my opinion this should be documented somewhere. (in case it is already, and I was just too stupid to find it, ignore this remark...) Problem when using the logging to network within a program that uses the parse_cmd library I can't explain why this is the case, but when you use the log server compiled for network output and afterwards start an application that uses "parse_cmdline" the logging will not go to network, but to local console (even if you specify "-nolocal" on the log server). If you're interested in this bug, I can send you my sample code which is just a modification of rt_sched example in the hello-package Regards, Rene

L4Linux Kernel Thread IDs
by Leon Brits 08 Apr '05

Hi all, I have a L4Linux kernel module which creates a kernel thread, but the new thread and the module has the same L4 thread ID [l4_myself()] while their PIDs are different as usual. Is this correct? Thanks Leon

con deprecated?
by Stefan Kalkowski 08 Apr '05

08 Apr '05

hello list, i want to do a new build of the l4-tree after building a new gcc. i got the problem, that packages like proxygon, that uses l4con-headers don't pass through, because the con-package is marked as deprecated since 2 days and it's Makefile is modified, so that it won't build. I think it's only a naming convention problem and there should be a l4con replacement? Or is there any other reason, why con is obsolet? greetings stefan -- Stefan Kalkowski GNU PGP-Key: https://www.inf.tu-dresden.de/~sk852421

Some questions with regard to emul_l4rm.c
by Leon Brits 01 Apr '05

01 Apr '05

Hi all, I am trying to understand the workings of the emul_l4rm.c. Please allow me to explain how I understand the working of this file so that you can correct me. When calling l4rm_attach(), the function l4rm_do_attach() gets called. This function calls reserve_virtual_area() which uses mmap(). Mmap() searches for an available area (with a certain size) in the calling process's virtual memory. After finding such an area it remaps memory, allocated using kmalloc() by /dev/zero, to the newly found virtual memory space. Kmalloc() allocates memory from the l4linux dataspace and that piece of memory is now mapped into user space. Next, the call to l4dm_map_pages(), maps my specified dataspace's pages into this mapped virtual address. Q1: Why go thru the first memory mapping of the kmalloc-ed memory into user space if immediately after it is remapped again by l4dm? Seems like a waste of the l4linux dataspace. Q2: Can the free virtual memory area be determined by another method and then call l4dm_map_pages()? Q2: When l4_fpage_unmap() is called, is the previous mapping to the pages of the kmalloc-ed memory restored? Thanks for your time. Leon

L4Linux hangs on self-compiled fiasco
by Björn Fischer 31 Mar '05

31 Mar '05

Hello, I am trying to build the complete DROPS including fiasco, DoPE and L4Linux. As a starting point I had the demo CD from the OS research day 2004. At first I used the binaries from the cd (including the config files) and ran them on top of vmware. Modules were loaded successfully via tftp and worked (well, when accessing the cd, L4Linux had the prob that there was no cd anymore, but at least the kernel worked well). After that I compiled the cvs tree and replaced the binaries by the own-compiled ones. It seems that fiasco and DOpE work fine since it renders nice windows and so on. But when it comes to starting L4Linux it crashes - well, in fact it just "hangs" and does nothing anymore. The weird thing is that the bootmessages, the ones printed in the "\ m /" window do not end at a reproducable point. Sometimes it comes up to "======> L4Linux 2.6 starting <========", sometimes only up to "loader : vmlinuz26,#d: Continue at l4env_init (00014264, libloader.s.so)", sometimes it hangs in the middle of a message. These are my config-files: menu.lst: --------- title L4Linux 2.6 from this CD [DOpE] kernel (nd)/drops/rmgr -sigma0 task modname "bmodfs" module module module module module module module task modname "l4dope" boot_priority 0xA8 modaddr 0x02000000 module (nd)/drops/fiasco -nokdb -nowait -noserial module (nd)/drops/sigma0 module (nd)/drops/names module (nd)/drops/dmon module (nd)/drops/dm_phys module (nd)/drops/simple_ts -t 380 module (nd)/drops/rtc module (nd)/drops/l4io --noirq module (nd)/drops/bmodfs module (nd)/drops/libloader.s.so module (nd)/drops/run.bmodfs.cfg module (nd)/drops/run module (nd)/drops/vmlinuz26 module (nd)/drops/vscrtest module (nd)/drops/cfg/l4linux26.cd.k_us.cfg module (nd)/drops/drops-rd.rd module (nd)/drops/l4exec module (nd)/drops/l4dope --l4io module (nd)/drops/proxygon module (nd)/drops/backdrop ------------------------- drops/cfg/l4linux26.cd.k_us.cfg: -------------------------------- sleep 1 task "vmlinuz26" "mem=64M noreplacement root=1:0 load_ramdisk=1 ramdisk_size=4096 l4env_rd=drops-rd.rd lang=us" allow_cli priority 0xA0 -------------------------------- Does anybody know what kernel options I could try to fix this?

Compiling the LOG server for net output
by Rene Wittmann 31 Mar '05

31 Mar '05

Hi, as I'm wanted to use the LOG server to log over the network, I changed the variable CONFIG_USE_TCPIP in the Makefile to 1. (in L4DIR/pkg/log/server/src) I tried to follow the instructions in the documentation of the LOG server (http://os.inf.tu-dresden.de/l4env/doc/log/p_faq.html#p_faq). So I tried to enable my driver in L4DIR/pkg/log/server/src/tcpip.c, but the file was not there! I'm pretty sure that I didn't remove it, so I guess it was not checked out... Is there a suitable file in the repository? If so, where? I didn't really care about that, so I tried to compile it, but of course it failed. (The error message: ==> Linking log LD_PRELOAD=/home/sirewitt/src/drops/l4/tool/gendep/libgendep.so GENDEP_TARGET=log GENDEP_BINARY=ld /usr/local/bin/gcc-2.95 -o log ../../../../../lib/x86_586/crt0.o logserver.o stuff.o flusher.o -Ttext=0x400000 -L../../../../../lib/x86_586/l4v2 -L/home/sirewitt/src/drops/drops/lib/x86_586/l4v2 -L../../../../../lib/x86_586 -L/home/sirewitt/src/drops/drops/lib/x86_586 -L../../../../../lib -L/home/sirewitt/src/drops/drops/lib -L../../../../../../oskit/lib -L/home/sirewitt/src/drops/drops/lib/oskit06 -T../../../../../lib/x86_586/main_stat.ld -static -lmain -lnames -ll4util -lparsecmdline -ll4serial -llog /usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.2.1/libgcc.a -static -lmain -llogserver -lnames -ll4util -lrmgr -ll4sys -nostdlib -Wl,--nostdlib -lmc -loskit_support -ll4util -lrmgr -lkern -llmm -lmc /usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.2.1/libgcc.a -lmc -Ttext=0x400000 -Wl,-gc-sections logserver.o(.text+0x3c9): In function `get_message': /drops/l4/pkg/log/server/src/logserver.c:204: undefined reference to `channel_get_next_fpage' logserver.o(.text+0x7b1): In function `main': /drops/l4/pkg/log/server/src/logserver.c:323: undefined reference to `channel_write' logserver.o(.text+0x7c1):/drops/l4/pkg/log/server/src/logserver.c:326: undefined reference to `channel_flush' logserver.o(.text+0x7d1):/drops/l4/pkg/log/server/src/logserver.c:329: undefined reference to `channel_close' logserver.o(.text+0x7e1):/drops/l4/pkg/log/server/src/logserver.c:336: undefined reference to `channel_open' flusher.o(.text+0xcb): In function `thread_loop': /drops/l4/pkg/log/server/src/flusher.c:105: undefined reference to `net_init' flusher.o(.text+0x16e):/drops/l4/pkg/log/server/src/flusher.c:123: undefined reference to `net_wait_for_client' flusher.o(.text+0x1bb):/drops/l4/pkg/log/server/src/flusher.c:146: undefined reference to `net_receive_check' flusher.o(.text+0x22f):/drops/l4/pkg/log/server/src/flusher.c:166: undefined reference to `client_socket' flusher.o(.text+0x38b): In function `do_flush_buffer': /drops/l4/pkg/log/server/src/flusher.c:242: undefined reference to `net_flush_buffer' collect2: ld returned 1 exit status make[3]: *** [log] Error 1 make[3]: Leaving directory `/home/sirewitt/src/drops/l4/pkg/log/server/src/OBJ-x86_586-l4v2' make[2]: *** [OBJ-x86_586-l4v2] Error 2 make[2]: Leaving directory `/home/sirewitt/src/drops/l4/pkg/log/server/src' make[1]: *** [src] Error 2 make[1]: Leaving directory `/home/sirewitt/src/drops/l4/pkg/log/server' make: *** [server] Error 2 ) So what do I have to do to get the net output working for the LOG server?

There, he gives me an error (page fault) at the stubs, when unmarshalling the return value of the woo_send() call, more precisely, when allocating the string(tag) inside the return structure. the line is the following: _dice_return.tag = (CORBA_char_ptr)(_dice_corba_env->malloc)(_dice_tmp_offset); i've checked the string size tha comes from the server and it is correct... So... why is it page faulting?? thanks in advance Tiago Jorge

Tracking IPC calls
by Julian Grizzard 29 Mar '05

29 Mar '05

All, We are working with the Fiasco kernel on x86 arch. We are trying to track IPC messages between processes and maintain a buffer of them in a data structure inside the kernel, maybe buffer to a deticated user space server later. Any pointers as to the best place to add our hooks? We've been playing around with l4/kernel/fiasco/src/kern/shared/idt.cpp. Not sure if we are on the right track or not? Any suggestions? Thanks! -Julian

Thank you for your prompt answers in my earlier issue. i don't know where i saw the underscore :). Now i'm having another issue. I'm having a page fault at my program because is trying to acess page 0. its a simple test program that starts an object that in the constructor starts a thread that uses FLIPS to have network. at the makefile i'm realocatting the program so i think the problem doesn't come from here. this is my Log: ####################################################### Welcome to Fiasco(ia32)!

Problem loading a module added to drops-rd

Hi all, I added a kernel module to the drops-rd ramdisk, but when I 'insmod' it I get the error: Floating point exception. I did enable kernel loadable modules without versions in the L4Linux kernel config. (Using l4linux-2.4.28) Any ideas why - and how to resolve this? Thanks Leon

how to port stdc++ ?
by Andrushka 09 Mar '05

09 Mar '05

I'm trying to port by self libstdc++. Please say me what is necessary steps compleat to build libstdc++.a ? I'm explored next: 1. Download stdc++ from GNU archives. 2. Modify config.sub (add drops target) 3. Modify configure add *-*-drops*) os_include_dir="os/generic" ;; 4. run ./configure --target=drops --host=i486-pc-linux 5. run make make all-target-libiberty all-target-libstdc++-v3 Please! Write in steps what are you doing to succesful build libstdc++ for L4Env!!! What changes and additions you made to raw libstdc++ sources? Maybe there are any guide ? Thanks.

hello... I've officialy gave up of porting L4vfs to the other libc :-). if i had more time i would do it. Now i'm only trying to use the most basic of C++ and STL. Is there any problem in using C++ + STL with the dielibc? What can't i use or can't i use at all the STL or the C++ stream package? thanks in advance Tiago Jorge

Second Problem Building L4ENV for L4Linux 2.6.10
by Dennis Newbold 09 Mar '05

09 Mar '05

Dear L4 Hackers, Following the instructions on the L4Linux website, I did a cvs checkout of l4linux-2.6 and l4linux-2.6-env Then, following the "Building" instructions, I cd'd to the l4 directory and typed in "make config", I then selected "Paths and Directories" to /root/drops (I had previously created /root/drops as an empty directory, and chmod'ed it to: chmod 777 drops). I exited "make config", selecting the "save configuration file option. Back in the l4 directory, I then typed in "make". It ran for several minutes, and finally failed trying to find an included file in a file named generic_io.idl. Shown below are the last several lines of make output preceding and relating to this error: -make[3]: Entering directory `/root/l4/pkg/generic_io/idl' PWD=/root/l4/pkg/generic_io/idl/OBJ-x86-l4v2 make -C OBJ-x86-l4v2 -f Makefile make[4]: Entering directory `/root/l4/pkg/generic_io/idl/OBJ-x86-l4v2' ...

problems building server following mini_http example
by Tiago Jorge 08 Mar '05

08 Mar '05

Hello... As i said in earlier emails, i'm building a L4 server that needs network support. For that purpose, i'm trying to use the libraries from the FLIPS package, using as guideline the mini_http server. i've build my own package and costumized the Makefile to suit my needs. I've changed the mode to l4env_freebsd because i'm using C++ + STL, and i need the headers and the libstdc++.a. I've changed also the needed extra libraries as in the mini_http example. So the Makefile looks like this: ###################################### PKGDIR ?= ../.. L4DIR ?= $(PKGDIR)/../.. TARGET = $(PKGNAME) # the default relocation address. This may be superseded by a STATIC file. DEFAULT_RELOC = 0x01d00000 # list your .c files here SRC_CC = FailureDetector.cc #Mode MODE = l4env_freebsd #systems SYSTEMS = x86-l4v2 # if your server implements the server side of an idl defined in an idl-file # of your package, list the idl file name(s) here (no path needed) #SERVERIDL = CXX_FLAGS = -nostdinc++ \ -I$(L4DIR)/include/g++-3 \ -I$(L4DIR)/include/drops # list additional library paths and libraries here LIBS = -lstdc++ $(GCCLIB) -ldiet_be_socket_io -ll4vfs_net_io -ldiet_be_select -ll4vfs_select -ll4vfs_select_listener-server include $(L4DIR)/mk/prog.mk ##################################### the result when i build my program is the following error: ...

[OBJ-x86_586-l4v2] Erro 2 But when i build the mini_http example it gives no errors and links some extra libraries that i don't see them defined in any file... My questions are: what am i doing wrong :) ? what extra libraries should i link and how? by the way... following my last email, to how to add extra NIC drivers to FLIPS, it is as simple as said and worked. Just add your drivers the referenced Makefile line and extra modules needed by the driver, in my case crc32 and mii. thanks in advance Tiago Jorge

l4linux error : no pgtab entry ...?

Hi I am running l4linux-2.4(2004/12/12) + fiasco(2004/12/12) on an intel pentium 4. When I try to give it access to my hard drive (/dev/hda1) I get the following error: KERNEL: no pgtab entry in sender: from [11]: 000c1000 size: 000c to [26] KERNEL: no pgtab entry in sender: from [11]: 000c1000 size: 000c to [26] KERNEL: no pgtab entry in sender: from [11]: 000c1000 size: 000c to [26] etc When I only give it access to the drops ramdisk, there is no error.

Hacking new NICs into flips
by Tiago Jorge 04 Mar '05

04 Mar '05

Hello... I've been seeing older mails about FLIPS and his drivers. In those mails, was refered the existence of a package to help porting linux drivers using DDE to FLIPS, but that wasn't available in the CVS. Is it already available? If not, how can i "hack" in to flips some new drivers? thanks in advance Tiago Jorge

Good evening. Has anyone ever built a L4/Fiasco server that uses OSKit or non-OSKit components to use the network, besides the tftp file provider? If so, could give me an hint how to do it, because i'm trying to do that for two weeks or so, without any sucess. thanks in advance TIago Jorge

Problem Building L4ENV for L4Linux 2.6.10
by Dennis Newbold 28 Feb '05

28 Feb '05

Dear L4 Hackers, Following the instructions on the L4Linux website, I did a cvs checkout of l4linux-2.6 and l4linux-2.6-env Then, following the "Building" instructions, I cd'd to the l4 directory and typed in "make config", I then selected "Paths and Directories" to /root/drops (I had previously created /root/drops as an empty directory, and chmod'ed it to: chmod 777 drops). I exited "make config", selecting the "save configuration file option. Back in the l4 directory, I then typed in "make". It ran for several minutes, and finally failed trying to assemble oskit10/kern/x86/pc/i16/i16_real_int.S. The error was on line 64.

IPC Timeouts
by Ronald Aigner 26 Feb '05

26 Feb '05

Hi, I am directing this question to both, the Karlsruhe and the Dresden, L4 mailing list, because I know both are working on new L4 specifications. (Background:) I am working with L4 in Dresden on real-time systems, which become fairly complex lately. One of the questions, which began to bother me more and more, is: What is the use of finite IPC timeouts? Ideally sending an IPC should be immediate (zero timeout) or should be performed eventually (infinite timeout). The only (useful) application of finite timeouts, I have seen so far, is the combination of multiple tasks in a single threaded server. That is waiting for IPC and for a regularly appearing timer event. (This sometimes implied adjusting the IPC timeout by the time used between the IPC waits.) Otherwise the use of finite timeouts is rather inconvenient, since the time used for the timeout depends on the whole surrounding system (software and hardware) and is thus impractical. I'm personally convinced that you do not need finite IPC timeouts. A single bit differentiating zero and infinte timeouts should be sufficient. To imitate the concurrent waiting for an IPC or timer event one could set up a timer with the kernel and inculde the "timer-source" into the receive scope of the wait IPC. Timer events can be dropped if the receiver is not ready. This would also simplify the tasks using IPC timeouts as timer event source. Coming back to my questions: What is the use of finite timeouts? Or maybe the question should be: Would it simplify kernel (and user land) design if seperating the concepts of finite timeouts and IPC? If you have reasons to include finite timeouts into future versions of the L4 Specification, please convince me. Thanks, Ron. -- Ronald Aigner ra3(a)os.inf.tu-dresden.de http://os.inf.tu-dresden.de/~ra3/

Linking a L4 library with a L4Linux app?
by Leon Brits 25 Feb '05

25 Feb '05

Hi all, I've been using a common library linked between three tasks in L4. I need to link this library with an application in L4Linux too also share info like the three L4 tasks has been doing. I've tried almost every variation off the Makefile I could think off, but the compiler always complain about stuff regarding library L4RM and L4DM_[MEM/PHYS] which I must include. The library also uses Semaphore- and Threads libraries. Any suggestions/reference/examples as to what to do to change a complex L4 library to be linked into a Linux application would be appreciated. Thanx Leon

deprecated practices in grub package - cause problem with gcc 3.4.2
by Jayesh Salvi 24 Feb '05

24 Feb '05

I recently installed Fedora Core 3 and tried to compile the grub package for L4 using gcc 3.4.2, I got some trivial compilation errors. Upon trying the compilation on different machine with gcc 3.1 I found some code following deprecated practices that escapes as warnings in < 3.4.2 but throws compilation errors with 3.4.2. Here are three such case I found in the grub package. If this is indeed the case it might be helpful to make the necessary changes to the repository code. ------------------------------------------------------------------------ ------------------------------------------------------------------ 1) stage2/builtins.c for gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3): builtins.c:886: error: missing terminating " character builtins.c:887: error: `Version' undeclared (first use in this function) builtins.c:887: error: (Each undeclared identifier is reported only once builtins.c:887: error: for each function it appears in.) builtins.c:887: error: syntax error before ':' token builtins.c:887:20: invalid suffix "x" on integer constant for gcc version 3.1: builtins.c:886:20: warning: multi-line string literals are deprecated 2)stage2/fsys_reiserfs.c for gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3): typedef unsigned int __u32; __u32 long j_mount_id; gives this error: fsys_reiserfs.c:115: error: long, short, signed or unsigned used invalidly for `j_mount_id' gcc version 3.1:allows it 3)stage2/smp-imps.c For switch-case construct: switch(i){ Case 1: break; ...

>I recently installed Fedora Core 3 and tried to compile the grub package >for L4 using gcc 3.4.2 don't use gcc 3.x to compile Grub. It has many things that aren't supported in earlier versions like strings in printfs scattered through several lines. My advice to you is use gcc 2.95. Also check if you have ncurses installed in your system. Use synaptic ;). It's easier. -- Tiago Jorge

Sorry. So if i want to use pthreads, i can't. Regarding to locks and to threads i can replace them by L4threads lib, that includes locks and threads. but what do you recommend to replace the usage of conditional variables? thanks for the aswers (and patience :)) Tiago

My X Window has a depth of 24, it's a TrueColor visual class. If you need more informations to solve this, just tell me. I would like to know: 1 - what's going on? I suspected some kind of weird IRQ firing because of the use of qemu, but as far as my investigations have told me, it doesn't seem to be that. I believed that one IRQ went to fast after a first one, so the linux was not yet out of the driver code, but the interrupts were enabled, thus crashing everything. I think I was wrong, no? 2 - how to solve this. What code/doc should I read to debug it, where to dig. I am a bit confused for now. Thank you by advance for your help. Best regards, Cedric.

Continuing the goal to port my aplication to an L4 server, i'm trying to use the OSKit lib to POSIX threads. I'm using c++ and building in l4env_freebsd mode. First of all, the static link to the lib wasn't in the modes.inc file. I've included it there. I've tried to build my test project, that simply starts a thread. The test files compiles but it doesn't do the static link. The error is the following: PWD=/home/tiago/l4/pkg/meumundo/server/src/OBJ-x86_586-l4v2 make -C OBJ-x86_586-l4v2 -f Makefile make[1]: Entrando no diretório `/home/tiago/l4/pkg/meumundo/server/src/OBJ-x86_586-l4v2' ...

L4Env compilation error
by Jayesh Salvi 17 Feb '05

I had my L4Env compiled last weekend, but after that I had to upgrade my linux to Fedora Core 3, which changed my compiler version. So I started compiling form scratch and I stumbled on this error.

Put it to something like /home/sirewitt/src/drops/drops, i.e. that it's beside the l4 directory (or somewhere else). Then redo everything, esp. oskit and oskit10. I don't how mangled your l4 directory is now, so maybe start from scratch? Adam -- Adam adam(a)os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/

The ansi.h file should come from /home/sirewitt/src/drops/include/oskit10/oskit/freebsd/machine Is that the case for you? What's your DROPS_STDDIR?

Problems with compiling DROPS packages
by Rene Wittmann 15 Feb '05

Hi, After checking out and compiling the L4/tool directory, the oskit,oskit10-directory (not the linux22-directory, it isn't needed for compiling the rest, right?), I have some problems compiling the DROPS packages in L4/pkg. I'm using a Suse machine with gcc-version 3.3, all the other requirements (described in "Building DROPS HowTo") are met by my system. (Instead of byacc I use bison, but this should be OK according to the mail archive). The output follows, any help/ideas would be appreciated.

That sounds promising Adam. But I am having this trouble with compiling L4Env. I downloaded all the stuff, and tried to compile the L4Env. But L4Env needs linux22 (I have no clue why?) I have that in ../l4linux22 directory, but inside a makefile in l4linux22/arch/l4/ there is a hard coded requirement for GCC to be 2.95 and my compilation stops at that point. I have GCC 3.3 something. Can someone tell me what should be done in this case? Thanks.

Thanks a lot. That helped a lot. F Everyone's I, More information on major and minor devices can be found at src/Documentation/devices.txt I had a boot CD for l4linux on fiasco. It was loading a ramdisk which was getting the binaries from CD. Since I was having no luck getting l4linux compiled, I decided to copy these binaries to hard disk and change the grub.conf to make it boot from hard disk. But after doing some intuitive things I found that it won't load l4linux until CD is put in. So I tried to learn how the bootloading takes place. In the process I stumbled upon this root=1:0 problem mentioned up in the thread. My ext3 root file system is installed on /dev/hda6, from the devices.txt file mentioned above I got that 1:0 stands for RAMdisk and for /dev/hda6 I will have to put 3:6. It worked (with the help of RAMdisk provided on l4linux download page).. However now I have come to know that there is no passing around compilation of L4Linux and L4Env, because the ram disk is designed for 2.6.8.1 and it looks for /lib/2.6.8.1... which I will need to build myself. Anyway. Thanks.

L4Linux bootprompt question

Hi, I an confused about the bootprompt arguments mention in the l4linux.cd.k_us.cfg file that is given to the loader to load the L4Linux 2.6 kernel. The line is : task "vmlinuz26" "mem=44M noreplacement root=1:0 load_ramdisk=1 ramdisk_size=4096 l4env_rd=initrd.gz panicblink=0 lang=us" What does root=1:0 mean? After referring to "The Linux Bootprompt - HowTo" http://ldp.rtin.bz/HOWTO/BootPrompt-HOWTO-3.html#ss3.1 I figured out that the argument is of the type root=/dev/* Can anyone help me understand what "root=1:0" mean?

Machine-independant handling of registers set with ptrace is tough.
by Etienne Robillard 31 Jan '05

31 Jan '05

Dear list, I'm actively into the process of hatching at the Fiasco-UX source-code, and have found the ptrace(2) interface to be quite entertaining. Firstly, the naming convention (ptrace macros) differs from Linux to FreeBSD. However, its relatively trivial to fix (thx to Alexander Julliard), by adding something like: #ifndef PTRACE_PEEKTEXT #define PTRACE_PEEKTEXT PT_READ_D #endif Secondly, a lot of things is done in `Usermode.cpp' in order to manipulate user-visible register set. In particular, I have to trust the effectiveness and the reliability of the following constructor: // save it to <machine/reg.h> struct user_regs_struct regs; regs.xfs = context->uc_mcontext.gregs[REG_FS] In comparison, the FreeBSD kernel implements the ptrace(2) proc_[read/write]_register(proc,regs) for doing this kind of stuff, but its not even close to be a member of uc_mcontext. All in all, it would be nice to know how (and why) this is done on different arch, and finally if the uc_mcontext.gregs constructor is the sole alternative to registers translation. Cheers, Etienne ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

Fiasco-UX build problem

Hi, I have a problem building Fiasco-UX. After checking out the latest sources, i had to do two workarounds to build all packages and the oskit. First i got the following error: ... make[3]: Entering directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit/examples' ld -Ttext 100000 -L../lib \ -o multiboot ../lib/multiboot.o multiboot.o \ -lkern -lmc -llmm ../lib/crtn.o /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/libgcc.a ld -Ttext 100000 -L../lib \ -o multiboot-gdb ../lib/multiboot.o multiboot-gdb.o \ -lkern -lmc -llmm ../lib/crtn.o /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/libgcc.a ld -Ttext 100000 -L../lib \ -o multiboot-smp ../lib/multiboot.o multiboot-smp.o \ -lsmp -lkern -lmc -llmm ../lib/crtn.o /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/libgcc.a ../lib/libsmp.a(boot.o)(.text+0x29): In function `_SMP_TRAMP_START_': : relocation truncated to fit: R_386_16 _SMP_TRAMP_32_ENTRY_ make[3]: *** [multiboot-smp] Error 1 make[3]: Leaving directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit/examples' make[2]: *** [examples/all.MAKE] Error 2 make[2]: Leaving directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit' make: *** [../oskit] Error 2 the Makeconf.bid can you find here: http://www.inf.tu-dresden.de/~sk852421/fiasco/Makeconf.bid and the full make output is here: http://www.inf.tu-dresden.de/~sk852421/fiasco/make.out So i deleted subdirectory examples and modified GNUmakefile. After that i got an error in the bootmod package: ... echo 'include $(L4DIR)/mk/lib.mk'>>OBJ-x86_K7-l4v2/Makefile PWD=/home/sk852421/Documents/uni/OS/Fiasco-UX/l4/pkg/bootmod/lib/src/OBJ-x86_K7-l4v2 make -C OBJ-x86_K7-l4v2 -f Makefile make[5]: Entering directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/l4/pkg/bootmod/lib/src/OBJ-x86_K7-l4v2' ...

L4Linux and serial port access from other tasks
by Julian Grizzard 26 Jan '05

26 Jan '05

Hi all, I'm running L4Linux on the Fiasco V2 microkernel on a Pentium IV. I am also running other L4 applications beside the L4Linux kernel. I would like to be able to print debug messages from those applications to the serial port. Messages print fine until L4Linux boots up. As best as I can determine, the problem is that L4Linux gets control of the serial port, and so no other tasks can use it. There may be a way to get this working using the L4Env setup; however, I am trying to keep a very minimal setup and so do not want to use L4Env. Can anyone provide some pointers on how to best go about restricting L4Linux's access to the serial port? Thanks! -Julian

L4Linux on AMD NF7-S

Hi. I'm trying to get l4linux to run on an AMD Athlon with a NF7-S mother board. I have managed to get linux to run, but only by removing the PCI bus support from the kernel completely. Other attempts at compiling the kernel have resulted in one of two errors when loading: loader | module path <(nd)/fiasco/hdboot> loader | <vmlinuz.l4env>, args <l4irqack=linux mem=64M no-scroll load_ramdisk= loader : 1 ramdisk_size=16384 root=/dev/ram0 ro l4env_rd=(nd)/fiasco/drops-rd. loader : rd> loader | <vmlinuz.l4env>: priority: a0 exec | vmlinuz.l4env: Loading tftp | Loading (nd)/fiasco/hdboot/vmlinuz.l4env [1146kB] exec | vmlinuz.l4env: Too many (>4) loadable program sections loader | vmlinuz.l4env: Error -2001 (EXEC: Invalid file format) while loading loader | ==> App successfully purged OR, Linux version 2.4.28-l4 (root@magenta) (gcc version 3.3.4 (Debian 1:3.3.4-9ubuntu5)) #99 Thu Jan 13 16:18:11 SAST 2005 69MB LOWMEM available. hm, page 00000000 reserved twice.

build report for Drops on FBSD
by Etienne Robillard 12 Jan '05

12 Jan '05

Hi, Here's the summary of what I've done to (almost) compile drops on FreeBSD 5.3-STABLE. - in l4/tool/gendep/syscall.c: Added #ifdef linux to wrap around missing <asm/unistd.h>. - Added $(LDFLAGS) to l4/tool/gendep/Makefile. - Told libgendep.so to link with `perl -MExtUtils::Embed -e ldopts` instead of '-ldl'. - Needed to configure drops with cpp33 instead of cpp0. - In $(OSKIT)/boot/boot_start.c, gcc complained about missing "" characters, so I added a bunch of them. - In $(L4DIR)/mk/Makeconf, I've added FIND=/usr/local/bin/gfind to avoid confusion with FreeBSD find (/usr/bin/find). I've told mk/include.mk to use $(FIND). Here's the latest official build-problem I've encountered: ...

Problem building the Pistachio 0.4 kernel
by Andreas Grosam 10 Jan '05

10 Jan '05

Hi All, this is my first attempt to compile the kernel. After installing L4/Pistachio and the tool chain for building a PowerPC kernel (on a PowerBook G4), i got this error message while compiling the kernel sources: pistachio-0.4/kernel/include/glue/v4-powerpc/tcb.h:330: error: can't find a register in class `GENERAL_REGS' while reloading `asm' I'm using gcc-3.4.3 as the cross compiler - compiled with the Apple tools. It doesn't seem that this error has something to do with the sources - more likely it is compiler related. I'm not a compiler guru, thus googling for that error message revealed some more information. Unfortunately no suggested solution for that specific problem seems appropriate. Furthermore, it turned out that this might be an optimization bug in the compiler. When using -O1 optimization when building the kernel (default is -Os), this error disappears. With stronger optimization it comes back. Do you have an idea how to workaround this error (gcc patches or prior versions, etc.)? Thanks in advance for any help! Regards Andreas

Network server + l4linux NIC stub driver
by sbrobson＠fastmail.fm 06 Jan '05

06 Jan '05

Hi all, I'm working on an system that runs multiple instances of l4linux. I would however like to set it up so that these instances share a network card, by means of a network server and stub driver interface. I have found a number of papers refering to such setups, including a reference to an OshKosh Network driver. Are such network servers available? Where can I get hold of one? Regards, steve. -- sbrobson(a)fastmail.fm

There seem to be 2 problems, the first one is that L4Linux has difficulties accessing the IDE controller. The second is related to IRQ 1. This happens on two different machines, so it's probably a configuration issue. However, I don't know where to start in order to fix this.

L4 come together at 21C3 in Berlin?
by Michael Engel 10 Dec '04

10 Dec '04

Hi, I just browsed through the 21C3 conference program - http://www.ccc.de/congress/2004/fahrplan-preview/fahrplan.html - and saw that at least some of the people involved in L4 development will be in Berlin (and, the better, give interesting talks). So, this is a good excuse to attend 21C3 (and let the University pay for it :-)) - are there eventually more L4 hackers attending the congress? Perhaps we could organize something like a BoF session... Btw., does anyone have a proposal for an inexpensive place to stay in Berlin from the 27th to the 30th of December? regards, Michael

Various questions
by Mattia Belletti 19 Nov '04

19 Nov '04

Hi all - I have some questions; I hope they have not already been posed! - I'm running a bare qemu + pistachio 0.4, and its kickstart + sigma0, with a little root server of my own, on a IA32 architecture. I ask for bootinfo location, and I find it's 0x1000 (that's where kickstart puts it, so it's ok). However, when I try accessing it, I obviously pagefault, but sigma0 refuses to give me that page. Anyway, if I _force_ it it to do (I've tweaked by hand source code), everything works fine - in fact the bootinfo is there, and it is correct. Did I get something wrong? - Little note: looking kickstart, I found this, around user/util/kickstart/mbi-loader.cc:486: if (use_bootinfo) { // Allocate and initialize a bootinfo structure. bi = init_bootinfo (&kip); rec = (L4_BootRec_t *) ((L4_Word_t) bi + bi->size); if (bi) // Record MBI modules rec = record_bootinfo_modules (bi, rec); else use_bootinfo = false; } (I'm referring to CVS version, If I remember well 0.4 version was exactly the same).

Stack Pointers for Exception Modes
by Wolfgang Johann BETZ 15 Nov '04

15 Nov '04

Hello, during my study of the bootstrap sequence of the L4/Arm source codes I have come to the following question: On which stacks get the exception handlers for exceptions like "fast interrupt" and "undefined instruction" executed and where in the sources get the (banked) stack pointers for these modes initialized? Thanks, Wolfgang

Various questions

I try to send this message again, since it seems it has not been posted: Hi all - I have some questions; I hope they have not already been posed! - I'm running a bare qemu + pistachio 0.4, and its kickstart + sigma0, with a little root server of my own, on a IA32 architecture. I ask for bootinfo location, and I find it's 0x1000 (that's where kickstart puts it, so it's ok). However, when I try accessing it, I obviously pagefault, but sigma0 refuses to give me that page. Anyway, if I _force_ it it to do (I've tweaked by hand source code), everything works fine - in fact the bootinfo is there, and it is correct. Did I get something wrong? - Little note: looking kickstart, I found this, around user/util/kickstart/mbi-loader.cc:486: if (use_bootinfo) { // Allocate and initialize a bootinfo structure. bi = init_bootinfo (&kip); rec = (L4_BootRec_t *) ((L4_Word_t) bi + bi->size); if (bi) // Record MBI modules rec = record_bootinfo_modules (bi, rec); else use_bootinfo = false; } (I'm referring to CVS version, If I remember well 0.4 version was exactly the same). The "rec = stuff" isn't wrong? If "bi" is set to NULL by the init_bootinfo (in case of OOM, if I remember well), this segfaults - well, don't know what it does exactly, since there's still no kernel around, and I don't remember IA32 defaults ;D - Looking L4 specs (even the latest - by the way, how come the sources theirselves aren't published?

Problem booting Fiasco on Pentium IV
by Julian Grizzard 10 Nov '04

10 Nov '04

Hi, I was able to boot Fiasco on a PIII 450 Mhz, 128MB. However, I have tried the same procedure on a Pentium IV 2.5GHz, 1GB RAM and it does not work. I get to this point in the boot process and it stops: |RMGR: Stage1 | loading /boot/sigma0 | loading kernel /boot/main -nokdb -nowait | kernel at 00300000-0039d624 | detected new-style DD-L4(v2)/Fiasco | configuring sigma0: 00090000-00095000, start: 00090000 | reserve modules memory range: 00223000-0022d175 | starting kernel /boot/main -nokdb -nowait proto=0x101fa0 @ 0x00300aa0 | |Loading ELF image (kernel) at 0x303140 [entry 0xf0001000] I used all the defaults when building L4, rmgr, sigm0, and hello. Is there anything special I need to do when booting on an PIV? I also created a floppy disk and booted it on both the PIII and the PIV. It boots on the PIII but not on the PIV. Anyone have any ideas as to what my problem is? Here is my grub configuration: |title hello world | root (hd1,0) | kernel (/boot/rmgr -sigma0) | module /boot/main -nokdb -nowait | module /boot/sigma0 | module /boot/hello Anything else I can provide that would be useful?

L4Env on freebsd
by granted14＠yahoo.com 03 Nov '04

03 Nov '04

Hi, Recently I had a few things that would need your opinions or advices.. Since dde is very hot, is it possible to have L4Env in perl5 or in any other kind of low-level langage? The reason is for not having to write very optimized L4 code in raw IDL format or in C, since I have pratically no expression with them*. I don't know how or if compilers like Dice or IDL4 currently play nice with dde_linux, nor if it could work with a hypothetic dde_to_any (kind-of) librairy**. Does implementing this in perl gives the ability to have a cool system in L4 (snesh), as with the Hurd or with L4-Linux, or elses? Best regards, Etienne Robillard * I guess -- it's like implementing L4 in any languages feels kludgy for me, with all respect to the sens of this word ;) ** Note 2: In dde-0.02 theres already headers for dde_linux. Are theses autogenerated or do someone cares for them ? I would love to see dde_lites.h or dde_freebsd.h :-) ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

My adventures trying to boot L4Linux kernel + Fedora
by Tiago Jorge 25 Oct '04

25 Oct '04

hello again. I've downloaded from the L4Linux CVS the version that matches more with the kernel that my Fedora Core brings, 2.4.22. I've made make menuconfig and, as instructed, removed all thing that messed with the hardware himself(APM, ACPI, etc), make, make modules and make modules_install. I've made mkinitrd to make a initrd file.

Building and Using the Fiasco µ-Kernel, new user
by Julian Grizzard 25 Oct '04

25 Oct '04

Hi all, I am just starting to look into the Fiasco microkernel for some research I am doing. This looks like a very neat project and you guys have done some great work! I have followed the build instructions located at: http://os.inf.tu-dresden.de/fiasco/use.html as a starting point and wanted to share the two problems I ran into. First, I could not get the "make config" to work on my gentoo system (gcc 3.3.4, make 3.80). This is what happened: $ make config make -C ./tool/config make: *** C-Compiler needs target arch. Maybe you mean HOST_CC. Stop. $ Not sure what the problem is. I noticed the message appears to be the contents of the ${CC_} variable in l4/mk/Makeconf. My work around was to compile on a redhat 8.0 box. Second, I had this problem when I booted the system: --init--------------------------------------EIP: f0010a0f jdb: Here is the grub configuration I used on the floppy (from http://os.inf.tu-dresden.de/fiasco/use.html): # this is /floppy/boot/grub/menu.lst title hello world kernel (fd0)/rmgr -sigma0 module (fd0)/main -nokdb module (fd0)/sigma0 module (fd0)/hello After digging around, I decided to change the thid line from "module (fd0)/main -nokdb" to "module (fd0)/main -nokdb -nowait". Is this correct? It seems to be working. Thanks! -Julian

The file name doesn't sound likes it's a rd. this file is a initrd file to the L4Linux kernel. What i'm trying to do is boot the Fedora that i have in the disk using the new kernel. But i think i have overcome the L4 problems. Now is just plain Linux Kernel problems (i think)... but tks for the help anyway. cheers Tiago <http://os.inf.tu-dresden.de/%7Eadam/>

Like we say here in portugal, i've been trying to "hammer" a solution, but didn't worked out. my grub.conf looks like this: title Fiasco + L4Linux root (hd0,0) kernel /fiasco/rmgr -sigma0 task modname "vmlinuz" module modaddr 0x02000000 module /fiasco/main -nokdb -nowait -serial_esc -comspeed 115200 -comport 1 module /fiasco/sigma0 module /fiasco/vmlinuz no-scroll no-hlt l4irqack=linux root=/dev/hda5 module /fiasco/2.2.27.img <===== i'm doing this beacause i can't use initrd is this the right way to do it? Im i missing something? he says that can't find a init and even when sometimes he loads the img, it crashes while loading it from disk. /dev/hda5 is my / partition. 2. Is it mandatory in L4Env boot to have the tftp server? can't i boot it from disk? Ok... i'm beeing very annoying for today, but i'll write a tutorial in the end :))) Thaks in advance Tiago

Problem booting L4Linux 2.4 + L4Env (Part 2)
by Tiago Jorge 21 Oct '04

21 Oct '04

hello to you all. I've sent my first email yesterday but i havent introduced myself. I'm Tiago Jorge, from the Faculty of Sciences of the University of Lisbon, and i'm doing my final work (Building a TCB using a u-kernel, in this case L4 plus all the additions that you and others have made for it). So, i wiil be "bugging" you for a short while from know :). Yesterday, i couldn't boot "names" server. Today i've have acheived that goal. I thank here all the fast aswers that people gave to me :). Today i've encountered another problem. This problem happens with the L4Linux kernel (i think!!), using it with his plain version and with his L4Env version, but i will focus on the L4Env version. Here is the log from the log server: ====================================================== Welcome to Fiasco(ia32)!

grub-0.95

11 Oct '04

Hallo, I adaped the patch for grup for grub-0.95. The grub in the Dresden CVS don't compile with gcc-3.3. and gcc-3.4.0 (as I tried it) Grub2 is very promissing, but it don't find the symbol tyble (as I tried it) I think it is a good idea to put the Dresdner grub enhancement in the official grub2. Greetings Rudolf Weber P.S: My new Notebook boots now from the net and the grub have now variables ... P.P.S: I have worked on RACE http://www.infnet.verein.de/produkte/race/ and dream to map ACE/RACE on L4 -- -- --------------------------------------------------------------- Rudolf Weber http://www.infnet.verein.de/~rw E-Mail: rfweber(a)tesionmail.de

C++ and dietlibc
by Leon 23 Sep '04

23 Sep '04

Hi all, I am trying to port (test) a small C++ app, which uses sockets, to the L4 environment. Most of the FLIPS examples uses the mode=l4env_base which includes dietlibc paths. I've tried to compile the app against libstdc++ and dietlibc but they do not seem compatible. The C++ app successfully compiles when using l4env_freebsd, but as soon as I include the Linux24/include directory to get the socket headers then there is a lot of clashes (duplicate defines) with the Oskit. This is obviously the reason for dietlibc in FLIPS, but the problem then is that dietlibc is not C++ compatible. With "compatible" I mean that some of the functions (like putc) is defined and not declared in the stdio.h file of dietlibc, which is then actually undefined in the cstdio file when the functions are moved to the STD namespace. Q1: Is this true - any suggestions? Thanks Leon

Fw: Re: Question about the OS Group
by R. Tyler Ballance 20 Sep '04

20 Sep '04

Anyways, minor question regarding the L4-Linux (or Fiasco for that matter) First off, I have some decent Compaq Pentium 1 desktops back home I could easily commandeer for hacking on. (I'm in college, so home is a 5 hour trip away) Will it run fine? I know system builds will suck, but it should work fine right? Secondly, I understand fully how a microkernel works, i've seen the schematics, flow charts, etc, but I'm confused at how a driver, for example, would be coded. Is it something that one hacks into userland? (Is it portable across L4 Operating Systems? (L4Linux, Fiasco, etc) Or does L4 have some special way of handling drivers? I know for example, that the Mach "microkernel" that Apple has bastardized for Darwin handles networking and such in the userland (it's been a while since i've played around on Darwin however) -Tyler ----------------- R.

FLIPS and l4linux
by Leon 08 Sep '04

08 Sep '04

Hi all, I've got a running system and some small programs running on Fiasco with DoPE and l4linux-2.4. I want to investigate FLIPS to use as an extension to one of the programs (network capable). The difference between compiling L4 and all its packages now is that I must set the parameter LINUX24_DIR to point to a directory with vanilla kernel code (I used 2.4.27) instead of previously when the parameter pointed to the L4LINUX directory (l4linux-2.4). The last one is currently my working setup. Q1: Was I doing it wrong the whole time and was just lucky to get it working? Anyway the newly compiled FLIPS system starts to load as usual but as soon as l4linux is loaded is stops with a cursor blinking below the penguin with NO text (console) output. Here is the debug output: EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly. Warning: unable to open an initial console. simple_t| ERROR: task #13 doesn't match: client 11.03, owner 0.00 l4lx | l4ts_create_task(): failed (server=A.00, ret=-3, exc 0) The system is still operational and I can start my programs from the "doperun" terminal. Q2: Any suggestions on why my l4linux does not want to load anymore? Thanks Leon

names for the L4 ipc functions for the x86 architecture
by Rafal Somla 26 Aug '04

26 Aug '04

Hi, I tried to compile and install Fiasco-ux and L4Env. It seems that the l4sys ipc functions for the x86 architecture have additional _i386_ part in their name. E.g., l4_i386_ipc_call instead of l4_ipc_call. The result is that, for instance, I can't compile the hello server without renaming the functions. Is that intentional or did I messed up the instalation? Thanks for any help on that, Rafal

RE: qemu and l4linux2.4
by Volkmar Uhlig 16 Jul '04

16 Jul '04

There is a bug in the current interrupt handler code. I'm not 100% sure but I think we have a patch to that. The problem is that with Pistachio we run APIC interrupt mode and when IRQs are disabled they usually get re-injected with a self-IPI (I'm not arguing about the sensibility of that strategy though). Right now L4Linux doesn't do that and the IRQ gets lost. - Volkmar > > -- > Mat/tia Belletti - Undergraduate student @ cs.unibo.it > ICQ: 33292311 - email: mbellett(a)cs.unibo.it > IRC: RedGlow - site(s): http://www.cs.unibo.it/~mbellett > Linux registered user 299762 @ Linux registered machine 213003 > > _______________________________________________ > l4-hackers mailing list > l4-hackers(a)os.inf.tu-dresden.de > http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers >

qemu and l4linux2.4

paper about l4
by Fabian Sturm 04 Jul '04

04 Jul '04

Hi! I just wanted to let you know that I wrote a small paper about the L4 Microkernel for a seminar in my school. It's a summary of many of the information which is available on the various websites. I doubt that it has much usefulness since the reference manual and other sources are more detailed and precise. But anyways some might be interested. http://www.rtfs.org/ext/l4_microkernel.pdf Thanks a lot, Fabian P.s. even I already gave my talk I still would be interested in any wrong claims given in the paper.

The error "tempfile: command not found" on compliing fiasco.
by Daniel Yu 04 Jul '04

Hi all: I meet the troubles when "make config" the fiasco. After the graphic configure setting, the make process is stopped by error: .......... echo INT_CPP_x86_NAME= 'cat $X.out' >> ./.Makeconf.bid.converted;\ rm -f $X $X.{c,out} /bin/bash: line1: tempfile: command not found. .......... I have browsed the source code of Makefile, there is one sentence: X='tempfile -s .c' . But there is not a command named tempfile in bash or /bin, /sbin. Then what's wrong about the error? Thanks!

The build error on l4linux and fiasco!
by Daniel Yu 01 Jul '04

01 Jul '04

Hello All: I am a newbie for using u-kernel: fiasco and l4linux. However, I meet some problems when building them. For building l4linux: Under redhat 9.0, kernel version is linux-2.4.20-8 and gcc version is 3.2.2. After typing the command: "make config". the error is as following: /bin/sh scripts/Configure arch/l4/config.in : command not foundline 51: ' script/Configure: line 72: syntax error near unexpected token `{ ' script/Configure: line 72: ' function mainmenu_option () { make: *** [config] Error 2 Under the same environment, it is successful to build linux-2.4.20 kernel. So what's wrong? For Fiasco building, I get the other error information:(Using fiasco-1.1) Malformed UTF-8 character (unexpected continuation byte 0xb5, with no preceding start byte) in substitution (s///) at /fiasco-1.1/tool/preprocess/src/preprocess line 672, <> line 2058. When compiling process went this place, it dies and I must use CTRL-C to stop it. Can you give me some suggestions? Thank yu all very much!

Hello L4 hackers ! I restarted to work on my project ADX (write a real time unix like OS on top of L4). In fact I restart from scratch. I did not work on it since two years, and all my old sources died with my old computer and its hard drive. I plan to port GNAT run-time on top of L4 and begin to write the servers on top of it. do this projet interest any body ? Thanks to contact me and give me your feeling about this project.

KernelInterface @ IA32

Hi L4 hackers, I'm a newbie in L4 and reading L4 X.2 spec. In IA32 interface, KernelInterface is implemented by 'lock: nop'. That really confuses me. Is it not just a placeholder? Any special side-effect? I can not find any clue in IA32 manuals. Yours truly, - Louis

ANNOUNCE: L4Ka::Pistachio version 0.4
by Espen Skoglund 04 Jun '04

04 Jun '04

The L4Ka team is happy to announce the release of L4Ka::Pistachio version 0.4. With L4Ka::Pistachio the L4Ka team aims at providing a robust, portable, high performance implementation of the L4 Version 4 API. It has been a long time since our last release, but we hope that all the new functionality and bug fixes were worth the wait. Among other things, the version 0.4 release adds support for 3 new hardware architectures. All in all the L4Ka::Pistachio kernel now runs on the following architectures: o Intel IA32 (Pentium and higher) o Intel IA64 (Itanium1, Itanium2, Ski) o AMD64 [NEW] o PowerPC 32bit (IBM 750) o PowerPC 64bit (Power3, Power4) [NEW] o Alpha (21164) o MIPS 64bit (R4000, VR41xx, R5000) o ARM (SA1100, XScale, ARM925T) [NEW] L4Ka::Pistachio version 0.4 incorporates a number of enhancements, modifications, and bug fixes. The following is a list of the major architecture independent changes since the last release: o Most system calls have been extended to report error codes upon failure. This substantially improves the ease of application development. o The kernel now implements "over-mapping" of flexpages correctly. Over-mapping occurs when a new page frame is mapped into the location of an already existing page frame in the destination address space. o Better support for reporting and resetting reference bits. o The ExchangeRegisters system call has been modified so that it can no longer activate inactive threads. o The L4 Version 4 API now specifies an architecture independent protocol for communicating boot loader specific data to the application programs. This protocol is supported by several L4 bootloaders (including kickstart). o Sigma0 now implements setting of memory attributes. o A bug (actually several bugs) in sigma0 would in some cases cause sigma0 to refuse to hand out certain memory regions, or cause incorrect memory to be handed out. o A new 'grabmem' example application has been added to the distribution. The following is a list of architecture specific changes and additions: Alpha: o Added FPU support. o Implemented SystemClock system call. AMD64: o This release adds support for the AMD64 architecture to L4Ka::Pistachio. o The AMD64 kernel is almost feature complete. It only lacks support for I/O flexpages and implementations of the Lipc, ProcessorControl and MemoryControl system calls. It also does not support SMP yet. o The kernel also features a hand-optimized fast IPC path. ARM: o This release adds support for the ARM architecture to L4Ka::Pistachio. o PLEB (Intel StrongARM SA-1100), Intel XScale IXP425 and TI OMAP1510 (ARM925T) platform support is included. o The kernel features fast address-space switching (FASS) [1] as a compile option. o The kernel is currently missing a fast-IPC path. Even without this optimization, context-switching and IPC performance across address spaces, when FASS is used appropriately, improves on any existing ARM implementation of L4 by approximately two orders-of-magnitude. o As with other architectures in L4Ka::Pistachio, currently no LIPC optimization is implemented - the LIPC path is identical to the IPC path. IA32: o Added a proper implementation of the SystemClock system call. o The support for small address spaces has been greatly improved. o Fixed a bug in the interrupt handing code that caused edge triggered interrupts to be handled incorrectly. o The kickstart utility now handles a number of command line options (see http://l4ka.org/projects/pistachio/kickstart.php for details). IA64: o The kernel now supports lazy handling of the upper 96 floating-point registers. o Preliminary support for performance profiling has been added. o Fixed a bug in the fast-IPC path that could cause interrupt handling to crash the kernel. o Low-level performance optimizations. o Fixed SystemClock system call to always report correct times. MIPS 64bit: o The kernel has been fixed to compile without debugging. o Added support for NEC VR41XX processors. o Changed the system call encoding. o The fast-IPC path has been fixed. o Reworked the exception handling code. o More accurate timer implementation. o Floating point support. o SMP support. PowerPC 32bit: o The kernel can run without debugging and without the debugger. o Proper exception message dispatching, including support for the system call exception. o Added correct implementation of the SystemClock system call. o Can prevent verbose kernel initialization. o Added a user-level I/O driver for the psim COM port, which can be used when the kernel is compiled without debug support. o Code restructuring to (1) minimize code, (2) improve readability, and (3) parameterize more kernel features. PowerPC 64bit: o This release adds support for the 64 bit PowerPC architecture to L4Ka::Pistachio. o The kernel supports Power3 and Power4 architectures (no SMP). o Optimized selective SLB replacement context switching on Power4. For more information on L4Ka::Pistachio and the L4 Version 4 API in general, refer to the L4Ka::Pistachio whitepaper: http://l4ka.org/projects/pistachio/pistachio-whitepaper.pdf L4Ka::Pistachio is available under the two-clause BSD license. Source and binary distributions, documentation, and other online resources can be found on the L4Ka website: http://l4ka.org/ The latest version of L4Ka::Pistachio, including any changes since the latest release, is also available through a public read-only CVS repository.

bochs/plex86 vs. qemu
by Yann Dirson 03 Jun '04

03 Jun '04

Hi Fiasco team, I see in http://os.inf.tu-dresden.de/fiasco/wishlist.html that someone had the idea that porting plex86 to L4 would be useful. Incidently, I had a similar idea a couple of weeks ago, but I was more thinking about qemu, so I was wondering whether qemu had been considered here. One major benefit I see is that qemu is a fast multi-architecture emulator (although only x86 support is complete for now, powerpc appears to be on good tracks), and would make it possible to run OS for arbitrary processors. Interested people can check it a thttp://fabrice.bellard.free.fr/qemu/ Best regards, -- Yann Dirson <ydirson(a)altern.org> | Why make M$-Bill richer & richer ?

ipc- where to send message(ipc).
by manish regmi 27 May '04

thanks, i got it. The client need to request tid of the server to name space server. But how much does it slows down a system. For example servers like i/o severs and fileservers need to be frequently called. Some systems like QNX decreases the no. of message passing by directly sending messages to file descriptor(fd) once a file is opened.i.e. directly send to i/o manager. will it be good to implement? thanks >Manish, > >(You were asking both the list and me, so I repeat here) > > > I am new to l4.

X.2-compatible L4Env
by Leonid Ryzhyk 11 May '04

11 May '04

Hi We are developing an operating system on top of Pistachio. At the moment we are looking for a framework which would allow to quickly port existing device drivers (e.g., from Linux) to our system as well as develop our own drivers. L4Env with its Omega0 server, l4io library and DDE seems to be a perfect match. Unfortunately, L4Env does not currently support Pistachio. L4hq site says that such support will follow shortly. Is this work being carried out, and, if so, when (approximately) will X.2-compatible L4Env be released? Thanks in advance. Leonid

Help with C++ and ide bus (oskit related, really stuck)
by Predrag Balorda 29 Feb '04

29 Feb '04

Ok here goes... I apologise if this may be slightly offtopic for l4-hackers but I seem to be stuck with something you people should have lot of experience with. Namely I'm trying to use OSKit (both official and DROP versions) to write a kernel in C++. I'm sure you're all aware of OSKit's unfriendliness toward C++ but there is one main thing that's preventing me from getting any work done. I'm starting off by creating some fairly thin wrappers around some structures and functions of oskit and once I've done that I'll go on and strip code out of oskit and re-write it in c++. But right now, there's a problem.... oskit_linux_init_osenv(environment); oskit_linux_init_devs(); oskit_linux_init_devs() hangs when the partition check kicks-in, somewhere in genhd.c, when doing msdos_partition(). If I compile one of the examples, x86/linux_fs_com.c with gcc everything works fine. However if I compile a c++ version of the same code, using same calls in the same order the linux genhd.c hangs when it tries to check partitions. And I get osenv_process_release with a hex dump. Anyone care to help me out here? funny how freebsd drivers work flawlessly though, isn't it? Thanks a lot and best regards! Pele P.S. I've tried with oskit10 from DROP but as soon as my kernel starts booting I get VGA garbage (vertical red lines) and the machine hangs. Actually it's not a machine, it's VMWare 4.0.5 but that shouldn't be a problem anyway. Note: all examples work fine so VMWare is not the problem.

Using hard disk as root filesystem
by tbisson＠soe.ucsc.edu 18 Feb '04

18 Feb '04

Hi, Thank you Adam for helping me solve the l4linux booting issue - adding modname "vmlinuz" module to the rmgr grub.conf linux fixed the rmgr error. As for, L4linux hanging, I had a bad configuration, which must have caused a race condition to pop up because after I changed my .config file around the kernel stopped hanging. I have another question. Rather than using a ramdisk as the root filesystem, I'd like to use my filesystem on /dev/hda3. So, I used this grub.conf, which I believe will use /dev/hda3 as the root fileystem: title L4Linux-2.4 kernel (hd0,0)/boot/drops/rmgr -sigma0 modaddr 0x2000000 module (hd0,0)/boot/drops/main -nokdb -nowait -serial_esc -comspeed 115200 -comport 1 115200 -comport 1 module (hd0,0)/boot/drops/sigma0 module (hd0,0)/boot/drops/vmlinuz.V2 root=/dev/hda3 The results are a standard boot (until kernel talks to disk) and dmesg displaying: ..... ide1 at 0x170-0x177,0x376 on irq15 hda: ide-disk driver hda: lost interrupt hda: host protected area => 1 hda: lost interrupt hda: 234441648 sectors (120034 MB) w/ 8192KiB Cache, CHS= 14593/255/63, UDMA(33) hda: lost interrupt hda: lost interrupt hdc: attached ide-cdrom driver hdc: lost interrupt hdc: lost interrupt hdc: ATAPI 52X CD-ROM CD-R/RW drive, 2048 Cache UDMA(33) Uniform CD-ROM driver Revision: 3.12 Partition check hda:<4>hda: dma_timer_expiry: dma status == 0x24 hda: DMA interrupt recovery hda: lost interrupt hda1 hda2 hda3 hda4 <<4>hda: dma_timer_expiry: dma status == 0x24 .... ds: no scocke drivers loaded! hda: DMA interrupt recovery hda: lost interrupt hda: dma_timer_expiry: dma status == 0x24 hda: DMA interrupt recovery hda: lost interrupt hda: dma_timer_expiry: dma status == 0x24 hda: DMA interrupt recovery hda: lost interrupt resiserfs: found format "3.6" with standard journal error wile mapping vm_allocated pages @ 10000002, error: e0, res: 40e0, fpage=80000033 KDB: pingpong no mapping --pingpong no mapping--------------------------------------------------------EIP: 00580c01 hard reboot time ---------------------------------------------------------------------------------------------------------------------------------------------------------- Additionally, I tried to boot up with regular ramdisk as the filesytems and mounting /dev/hda3 and then chrooting over, but that fails with a : FATAL: kernel too old message. _________________________________________________________________________________________ My questions: 1. Have you guys had success in using root=/dev/hda(x) in grub? If so, are there any tricks? 2. Is it typical for keyboard mappings to be wrong with l4linux? For example, my forward slash is now shift-7 and my dash is forward slash. 3. Has anyone seen the FATAl: kernel too old message before? Who is the kernel to old for, the filesystem? I apologize if these questions are inappropriate, Tim

Getting L4Linux2.4 to boot

Hello, My research group has decided to experiment with the DROPS operating system and I have been designated as the guinea pig to get it running and see what we have been missing out on. I'm currently trying to get fiasco to work with L4linux-2.4. However, I am unfortunately failing in my task. I can't seem to get l4linux to fully load with fiasco; it hangs at the boot-up command: .... Linux NET4.0 for Linux 2.4 Based upon Swansea University Computer Society NET3.039 Initializing RT netlink socket starting kswapd Journalled Block device driver loaded <-system hangs here (with every grub.conf I try) ------------------------------------------------------------------------- With these two grub confs: title L4Linux-2.4 kernel (hd0,0)/boot/drops/rmgr -sigma0 modaddr 0x2000000 module (hd0,0)/boot/drops/main -nokdb -nowait -serial_esc -comspeed 115200 -comport 1 module (hd0,0)/boot/drops/sigma0 #modaddr 0x0080000 module (hd0,0)/boot/drops/vmlinuz.V2 no-scroll no-hlt l4irqack=linux load_ramdisk=1 ramdisk_size=16384 root=/dev/ram0 module (hd0,0)/boot/drops/drops.rd title L4Linux-2.4 kernel (hd0,0)/boot/drops/rmgr -sigma0 modaddr 0x2000000 module (hd0,0)/boot/drops/main -nokdb -nowait -serial_esc -comspeed 115200 -comport 1 module (hd0,0)/boot/drops/sigma0 #modaddr 0x0080000 module (hd0,0)/boot/drops/vmlinuz.V2 no-scroll devfs=mount ramdisk_size=16384 root=/dev/ram0 console=tty module (hd0,0)/boot/drops/drops.rd I get this error after it says it is trying to load the ramdisk: RMGR: #05: loading "/boot/drops/vmlinuz.V2 no-scroll no-hlt l4irqack=linux load_ramdisk=1 ramdisk_size=16384 root=/dev/ram0 " from 02057000-022d0d80 to [ 003ff000-00606b20 00607000-00654984 00656000-0067e00 00672000-006d66500 ] at entry 003ff000 via trampoline page code 0005e1ac RMGR: #06: loading "(hd0,0)/boot/drops/drops.rd" from 0022d1000-062d1000 to [ ] ERROR: exec_load() failed with code 6000 RMGR: boot error. Return continues, Esc panics, "m" shows memory map So I press enter and it linux loads until the "Journalled Block Device driver loaded" line. ------------------------------------------------------------------------------------------------------------------------ However, when I try this conf: title L4Linux-2.4 kernel (hd0,0)/boot/drops/rmgr -sigma0 modaddr 0x2000000 module (hd0,0)/boot/drops/main -nokdb -nowait -serial_esc -comspeed 115200 -comport 1 module (hd0,0)/boot/drops/sigma0 #modaddr 0x0080000 module (hd0,0)/boot/drops/vmlinuz.V2 root=/dev/hda3 no-scroll I don't get the load the ramdisk error (for obvious reasons), but my system still hangs at the same point. ---------------------------------------------------------------------------------------------------------------- I suspect the reason my system stalls at the line "Journalled Block Device driver loaded" is that there is no file system for which linux to run on? I hope that one of the l4-hackers has experienced something similar and can enlighten me as to why loading the ramdisk is causing an error and a suggestion of how get the ramdisk to load properly with RMGR so that booting l4linux doesn't hang.

Hi, I have some feature requests for L4Linux 2.4(L4Env): My kernel paniced, because I didn't read the Howto on the webpage correctly and the I couldn't do anything with my computer, except pressing the reset button. Could it by possible to enter ther kernel debugger when panicing? On the webpages: A description on how to use L4Linux with DOpE would be helpful. Ron. -- Mit freundlichen Gruessen / with regards ra3 @ inf.tu-dresden.de http://os.inf.tu-dresden.de/~ra3/
