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

Network L4 servers
by Tiago Jorge 02 Mar '05

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. Shown below is command used to assemble this file, and the llines following it, from the output of "make": gcc -c -o i16_real_int.o -MD -DHAVE_CONFIG_H -DOSKIT_X86 -DOSKIT_X86_PC -I. -I../kern/x86 -I../kern/x86/pc -I../kern/x86/dos -I../kern/x86/i16 -I../kern/x86/pc/i16 -I../kern/x86/dos/i16 -I../kern -I- -I../oskit/c -I.. -I.. -nostdinc -D_GNU_SOURCE -DASSEMBLER -MD ../kern/x86/pc/i16/i16_real_int.S ../kern/x86/pc/i16/i16_real_int.S: Assembler messages: ../kern/x86/pc/i16/i16_real_int.S:64: Error: bad expression ../kern/x86/pc/i16/i16_real_int.S:64: Error: junk `1-0x00000200' after expression make[3]: *** [i16_real_int.o] Error 1 rm x86_asm.symc x86_asm.symc.o trap_asm.symc trap_asm.symc.o pc_asm.symc pc_asm.symc.o make[3]: Leaving directory `/root/oskit10/kern' make[2]: *** [kern/all.MAKE] Error 2 make[2]: Leaving directory `/root/oskit10' make[1]: *** [all] Error 2 make[1]: Leaving directory `/root/oskit10' make: *** [../oskit10] Error 2 I checked everything out of CVS on 2/27/2005, PST (i.e., Loa Angeles, California, USA time).

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; ...
