Booting L4Linux on Raspberry Pi 2
by Antoine DEBUT 21 Mar '16

21 Mar '16

Hello l4-hackers, Since I was able to correctly set up my l4re for the Raspberry Pi 2 thanks to Adam, I did a bunch of tests on the board with custom programs and following the examples on the l4/pkg/examples directory. Therefore, I am now struggling with the ultimate test: booting and using L4Linux. I am trying to boot a vanilla L4Linux, using the entry 'L4Linux-basic' given in the default modules.list. Upon booting, L4Linux delivers this error : [...] l4linux | List of all partitions: l4linux | 0100 4000 ram0 (driver?) l4linux | 0101 4000 ram1 (driver?) l4linux | 0102 4000 ram2 (driver?) l4linux | 0103 4000 ram3 (driver?) l4linux | 0104 4000 ram4 (driver?) l4linux | 0105 4000 ram5 (driver?) l4linux | 0106 4000 ram6 (driver?) l4linux | 0107 4000 ram7 (driver?) l4linux | 0108 4000 ram8 (driver?) l4linux | 0109 4000 ram9 (driver?) l4linux | 010a 4000 ram10 (driver?) l4linux | 010b 4000 ram11 (driver?) l4linux | 010c 4000 ram12 (driver?) l4linux | 010d 4000 ram13 (driver?) l4linux | 010e 4000 ram14 (driver?) l4linux | 010f 4000 ram15 (driver?) l4linux | No filesystem could mount root, tried: ext3 ext2 ext4 cramfs l4linux | Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0) l4linux | CPU: 0 PID: 1 Comm: swapper Not tainted 4.3.0-l4 #2 l4linux | Hardware name: L4 l4linux | [<0200cb88>] (unwind_backtrace) from [<0200583c>] (show_stack+0x10/0x14) l4linux | [<0200583c>] (show_stack) from [<020627a4>] (panic+0x7c/0x1cc) l4linux | [<020627a4>] (panic) from [<02354df0>] (mount_block_root+0x25c/0x29c) l4linux | [<02354df0>] (mount_block_root) from [<023550f4>] (prepare_namespace+0x160/0x1b4) l4linux | [<023550f4>] (prepare_namespace) from [<02354a40>] (kernel_init_freeable+0x178/0x1c0) l4linux | [<02354a40>] (kernel_init_freeable) from [<0227409c>] (kernel_init+0x8/0xec) l4linux | [<0227409c>] (kernel_init) from [<02007e34>] (ret_from_fork+0x14/0x20) l4linux | [<02007e34>] (ret_from_fork) from [<00000000>] ( (null)) l4linux | ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0) l4linux | ------------[ cut here ]------------ l4linux | WARNING: CPU: 0 PID: 1 at /home/adebut/Documents/L4Hyperviseur-LBNV/l4re-snapshot-2015123115/src/l4linux/arch/l4/kernel/main.c:2148 l4x_blink+0x10/0x50() l4linux | Modules linked in: l4linux | CPU: 0 PID: 1 Comm: swapper Not tainted 4.3.0-l4 #2 l4linux | Hardware name: L4 l4linux | [<0200cb88>] (unwind_backtrace) from [<0200583c>] (show_stack+0x10/0x14) l4linux | [<0200583c>] (show_stack) from [<0201dee4>] (warn_slowpath_common+0x78/0xb0) l4linux | [<0201dee4>] (warn_slowpath_common) from [<0201dfb8>] (warn_slowpath_null+0x1c/0x24) l4linux | [<0201dfb8>] (warn_slowpath_null) from [<02001af0>] (l4x_blink+0x10/0x50) l4linux | [<02001af0>] (l4x_blink) from [<0206289c>] (panic+0x174/0x1cc) l4linux | [<0206289c>] (panic) from [<02354df0>] (mount_block_root+0x25c/0x29c) l4linux | [<02354df0>] (mount_block_root) from [<023550f4>] (prepare_namespace+0x160/0x1b4) l4linux | [<023550f4>] (prepare_namespace) from [<02354a40>] (kernel_init_freeable+0x178/0x1c0) l4linux | [<02354a40>] (kernel_init_freeable) from [<0227409c>] (kernel_init+0x8/0xec) l4linux | [<0227409c>] (kernel_init) from [<02007e34>] (ret_from_fork+0x14/0x20) l4linux | [<02007e34>] (ret_from_fork) from [<00000000>] ( (null)) l4linux | ---[ end trace 5ed140c2c802ee32 ]--- l4linux | panic: going to sleep forever, bye l4linux | panic: going to sleep forever, bye I cannot find any related mail on this mailing list, and therefore must ask you for some help.

Problems running example isr
by Nourhan Mohamed 21 Mar '16

21 Mar '16

Dear L4Hackers, I have a problem running the example "isr" in the pkg/examples/sys/isr folder in l4 source. It prints "isr | Press keys now, Shift-Q to exit" then It fails to detect any interrupts and just keeps waiting. My configuration is as follows, emulated using Qemu on vexpress-a15 machine: modules.list: entry isr kernel fiasco -jdb_cmd=JS -serial_esc roottask moe rom/ex_isr.cfg module ex_isr.cfg module isr module ned module l4re module keyboard.io module arm-ve.devs module io module cons arm-ve.devs: -- vim:set ft=lua: local Res = Io.Res local Hw = Io.Hw Io.hw_add_devices(function() KBD = Hw.Device(function() Property.hid = "AMBA KMI Kbd"; compatible = {"arm,pl050","arm,primecell"}; Resource.irq = Res.irq(44); Resource.regs = Res.mmio(0x1c060000, 0x1c060010); end); end) keyboard.io: local hw = Io.system_bus(); Io.add_vbus("keyboard", Io.Vi.System_bus { amba = wrap(hw:match("arm,pl050")); }) ex_isr.cfg: local L4 = require("L4"); local loader = L4.default_loader; vbus_key = loader:new_channel(); local cons = loader:new_channel(); loader:start( { caps = { cons = cons:svr() }, log = L4.Env.log, }, "rom/cons -k -a" ); L4.default_loader.log_fab = cons; loader:start( { caps = { sigma0 = L4.cast(L4.Proto.Factory,L4.Env.sigma0):create(L4.Proto.Sigma0); icu = L4.Env.icu; keyboard = vbus_key:svr(); }, l4re_dbg = L4.Dbg.Boot, log = {"IO", "magenta"}, }, "rom/io -vvv rom/arm-ve.devs rom/keyboard.io"); loader:start({ caps = { icu = L4.Env.icu; vbus = vbus_key }, log = {"isr", "cyan", "key=1"}, }, "rom/isr"); where "rom/isr" refers to the example file "isr/main.c" provided.

You have not provided enough information. For example, how you compile Fiasco, L4Re and L4Linux. My experience with L4Re tells me you probably forgot to enable VFP/NEON in configuration options - check the menuconfig for Fiasco, L4Re and L4Linux. Most likely what happened is that the newer toolchain is by default using the "hardfloat" ABI and the compiler generates VFP/NEON instructions. If that fails, I suggest that you try debugging it yourself Therefore, there are several places you should look at: 1) First, you could try running the app under gdb. It will then print the stack trace and point to the offending instruction. 2) You could also install a SIGILL handler in your app and see what's the actual instruction causing the fault. I have an example code here - https://gist.github.com/astarasikov/9369538#file-arm-sigill-example-L71. It's actually a complicated example that patches the code at runtime. What you need to look at is at the following lines in "my_sh": # ucontext_t *uc = (ucontext_t*)data; # struct sigcontext *ctx = &(((ucontext_t*)uc)->uc_mcontext); # ctx->arm_pc; //this is the address of the instruction. You can printf it (as an unsigned integer) and decode the instruction. 3) If that fails, you could patch the invalid opcode handler in kernel to print the instruction. You should grep "arch/arm" and "arch/l4" for "SIGILL". Then, you can add the code to the trap handler. Alternatively, if you build kernel with CONFIG_DEBUG and CONFIG_DEBUG_USER, you will be able to see the stack trace and the hex dump of the instruction in the "dmesg" (or on the serial port console). > > (My project is stable on the old snapshots, that's why i try to avoid > migrating to current snapshot.) > > > > thanks, > ba_f > > _______________________________________________ > l4-hackers mailing list > l4-hackers(a)os.inf.tu-dresden.de > http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers -- Regards, Alexander -- Regards, Alexander

L4linux IPC communication with L4re application
by Ahmed Makkawi 15 Mar '16

15 Mar '16

Hi all, I think the solution to the communication of an application on l4linux with an application on l4re would be to implement an ipc stream in the character device module in the l4linux kernel to communicate with the IPC stream on l4re application. the Problem now is l4linux modules are in C and the l4re application is in C++, is this a good idea to start searching in it or its a dead end and maybe someone would have a better idea to work on ?

FYI: microkernel.info community site
by Jakub Jermář 14 Mar '16

14 Mar '16

Hello, just FYI, I have set up a simple web page[1] to promote the wider microkernel community and its goals. So far, the page comes with a brief description of the microkernel concept and an incomplete list of microkernel projects with links to each project's web. The description is made out of the first two sentences I found in the "What is XYZ" section or elsewhere on the web of the respective project. I also took the freedom to use the respective project's logo (or what I believed was the project's logo) for promoting it. I hope you will find this small web a good idea. It was inspired by a similar (though a little bit more informative) site set up by the unikernel community [2]. The sources of the [1] web are hosted on Github [3], so feel free to submit issues or PR to make the site better. Please send me a PM if there are any issues pertaining your project's cartouche that cannot be dealt with using Github. Thanks, Jakub [1] http://microkernel.info [2] http://unikernel.org/projects/ [3] https://github.com/jermar/microkernel.info

Running the Bro IDS on an ARMv7 board.
by Mahdi Aichouch 03 Mar '16

03 Mar '16

Hello, I tried to run the Bro IDS on top of L4Linux and L4 Fiasco, on a Freescale i.MX6 ARM cortex A9. Starting the Bro program produces an unrecoverable error and make the L4 Fiasco enter an endless loop as shown below : Does anyone was able to run the Bro IDS on top of L4Linux on a ARMv7 board. Does someone has idea of how to track down the problem. Thank you very much in advance.

Hi, Manolis I renamed the file but I didn't know that a download link of it was broken.. :) So, Share "L4/Fiasco/L4Linux : Porting and Device driver guide on ARM (imx6q cortex-a9)" ,again. :-) http://developerpostit.blogspot.kr/2014/08/device-driver-guide-on-l4linux.h… The guide PDF can be downloaded on this page.

L4Linux with IPC
by Ahmed Makkawi 25 Feb '16

25 Feb '16

Hi All, Im trying to make a simple communication between an application running on L4linux and application running on L4re, so far I managed to make a server client application running on L4re to communicate using IPC, but I dont know how to make the L4Linux take the msg from the IPC channel and pass it to the character device I have running on L4Linux and vice versa. BR, Ahmed Makkawi

Compiling GPIO drivers for L4Linux
by Nourhan Mohamed 23 Feb '16

23 Feb '16

Dear all, Unlike the normal Linux (version 4.3.0) kernel configuration, when compiling the L4Linux (same version) kernel I couldn't find an option to enable GPIO or choose a driver for the architecture I am building upon (Since I am compiling for ARM, Versatile Express Cortex-A15 board over qemu). Is there an option to enable gpio for l4linux? I even tried modifying something in the gpio driver src in l4linux and when I re-compiled, it never detected any changes. BR, Nourhan

GPIO access on L4Linux
by Nourhan Mohamed 08 Feb '16

08 Feb '16

Hi all, Does anyone has a rough idea of the steps that should be carried to make L4Linux see GPIO pins? I mean when I navigate to /sys/class I have no gpio folder. So since I am new to this can anyone tell me what steps should be carried out? Thanks in advance, Nourhan
