Porting Fiasco + L4Re to Raspberry Pi 2
by Antoine DEBUT 26 Nov '17

26 Nov '17

Hello l4-hackers, I am currently working on porting the Fiasco.OC micro kernel onto the Raspberry pi 2. Therefore, I am struggling with memory mapping, and I encounter the following error when launching the default 'hello' entry: L4 Bootstrapper Build: #2 Tue Feb 23 11:57:19 CET 2016, 4.8.3 20140303 (prerelease) Scanning up to 1024 MB RAM, starting at offset 32MB Memory size is 1024MB (00000000 - 3fffffff) RAM: 0000000000000000 - 000000003fffffff: 1048576kB Total RAM: 1024MB … [View More]Scanning fiasco Scanning sigma0 Scanning moe Moving up to 5 modules behind 1100000 moving module 02 { 10db000-110c4d7 } -> { 11cc000-11fd4d7 } [201944] moving module 01 { 10c9000-10da373 } -> { 11ba000-11cb373 } [70516] moving module 00 { 1043000-10c889f } -> { 1134000-11b989f } [546976] moving module 04 { 1029000-10425af } -> { 111a000-11335af } [103856] moving module 03 { 100f000-102849b } -> { 1100000-111949b } [103580] Loading fiasco Loading sigma0 Loading moe find kernel info page... found kernel info page at 0x2000 Regions of list 'regions' [ 1000, 1aff] { b00} Kern fiasco [ 2000, 92fff] { 91000} Kern fiasco [ 93000, 930eb] { ec} Root mbi_rt [ c0000, c9c33] { 9c34} Sigma0 sigma0 [ d0000, d6177] { 6178} Sigma0 sigma0 [ 140000, 16905b] { 2905c} Root moe [ 170000, 17b58b] { b58c} Root moe [ 1000000, 100e4ff] { e500} Boot bootstrap [ 1100000, 1133fff] { 34000} Root Module API Version: (87) experimental Sigma0 config ip:000c0100 sp:00000000 Roottask config ip:00140250 sp:00000000 Starting kernel fiasco at 000012b8 Non-HYP kernel detected but running in HYP mode, switching back.

I am currently working on the latest snapshot (2015123115), with U-Boot as a bootloader, and testing on a real board (Raspberry Pi 2 model B V1.1). The entry built is the standard 'hello', and I use the ramdisk-arm.rd given in the snapshot. I did add a custom Bsp for the board, mainly based on the first Raspberry Pi except for the Base Address, that is 0x3F000000 instead of the first Pi's 0x20000000. I highly think that it is an address configuration problem, because it first happened when I did expand the RAM size to 1024MB. With further investigation, I found out that it was the kernel memory allocation that causes this error, and suspect an incorrect MMU mapping. This suspicion comes from the fact that the assertion takes the address _base (0xf0400000) and the currently allocated block (0xee100000). I did not modify any parameter in the kern/arm/mem_layout-arm.cpp file on the Fiasco directory, which provides the default ARM addressing. Maybe that's where my error comes from ? How can I correctly configure my memory mapping, besides what I already configure in the Bsp (given in attachment) ? Also, it is the first time that I am assigned for porting a system, do you have some hints, like important steps to follow ? I am pretty sure it is a newbie error, but I cannot figure it out for now :( Thanks in advance for your time, -- Antoine Debut EPITA 2016 - GISTRE [View Less]

Graphical desktop, l4con, mag
by teclis High Elf 02 Jun '17

02 Jun '17

Guten Tag, I've got the Hello app runing with fiasco and l4re in qemu, how do I get the graphical UI and console running that I see on the screen shots page? Do I need to use l4con and mag? I don't see an entry with l4con in modules.list. danke * <http://german.about.com/library/media/Audio/gutentag.wav>*

libfs/ FUSE on L4Re
by Stark, Josef 31 May '17

31 May '17

Hello, yesterday I came across a very interesting paper titled "Porting FUSE to L4Re", accessible here: http://os.inf.tu-dresden.de/papers_ps/pester-beleg.pdf For porting FUSE, the author uses a library called "libfs" which provides filesystem request forwarding and processing, if I understood correctly. It reads as if libfs is already included in L4Re. However, I couldn't find neither FUSE nor libfs in the current L4Re snapshot. Are they by any chance publicly available somewhere else, or are … [View More]

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 [View Less]

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 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.

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

Dear all, I wanted to create a simple character device on L4Linux. I managed to cross-compile the module and run it on L4Linux on Versatile Express Realview Cortex-A15 ARM machine using the following command: make -C ~/l4re/obj/l4linux/arm-mp/ M=$PWD CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- L4ARCH=arm CONFIG_TCG_TPM=m modules V=1 When I try to insert the module using the insmod command I get the following printed out from the module: chardev: registered correctly with major number 254 … [View More]
