Re: L4Linux boot stop "param_word bits 16-19 must be 0. Fix yourbindings!"

When entering the kernel debugger, you should get a line similar to this: ---------------------------------------------------ESP:201807a8 EIP:00006526 (6.00) jdb: 6.00 in this case is the thread that was active, when the debugger was entered (thread 0 of task 6).

Compare it to the task numbers that "rmgr" or "loader" report when starting tasks, i.e. RMGR: loading "pingpong-ux" from 01d37000-01d6f72d to [ 00800000-0080f1c3 00810000-00960580 ] task #0x06 at entry 00800000 via trampoline page code 00070150 ^^^^^^^^^^ Task 6 is pingpong-ux or loader | vmlinuz.l4env,#f: Continue at l4env_init (00013350, libloader.s.so) ^^^^^^^^^^^^^^^^ Task 0x0f is L4Linux And voila, you'll find the offending program that needs fixing.

New cli/sti semantics in Fiasco 1.0?
by Jacob Gorm Hansen 30 Aug '03

30 Aug '03

hi, as far as I recall, Fiasco used to re-enable interrupts upon returning from a syscall, even if they had been disabled before the syscall. Some of my old code (my patched version of L4Linux22 which I am using with nomadbios) seems to have relied on this behaviour and now fails with a "page fault in cli mode" on the first intruction after an IPC-operation. Am I correct that the behaviour has been changed like this, or do I just have to configure my Fiasco differently? The old Fiasco I am using is from CVS about a year ago. thanks, Jacob

l4/pkg/con etc
by David Denny 30 Aug '03

30 Aug '03

Hello Hackers. Having got to the stage of compiling successfully my second (debian) hello+fiasco+glinux set, I'm now looking at cool next step (read: "easy wins for the temporally challenged"). UX and CON seem to be my candidates. OK, UX looks more like the world I'm used to, so I won't ask about that yet. But I /do/ have a Q. about the drops con, which has wider learning implications, so a few hints here won't go amiss. My guess is that to yield up a con binary, I cd to l4/pkg/con, "make", and /no/ that isn't it because it falls over... my predecessor instructions were per website, CVSco, compile hello and fiasco using gcc3.2, compile linux22 using gcc2.95. so: how do I compile "con" and other packages, please? (or: a generalised rule to cover this) ;-) TIA David D

Driver using DDE
by Chris Lambert 26 Aug '03

26 Aug '03

Hello, we try to implement drivers for DROPS using the DDE, but we only have the sounddriver described in the diploma thesis of Christian Helmuth. Are there other sample drivers (smaller) available for us to see how to use DDE? It's part of a project at Operating Systems Chair at University of Saarland.

Thanks all
by David Denny 25 Aug '03

25 Aug '03

Well we now have fiasco booting Hello, and more or less satisfactory boots of cpufreq and pingpong, on SuSE8.2 with reverted compiler (3.2). Thanks ALL for your assistance. My next steps are to get a L4Linux working on SuSE8,2 and then repeat for Debian. The side effects are of course swapping compilers and libraries in and out of the host OS. I should like to see after that if I can get the DoPE demo working properly. I am guessing so far that it may be some underlying library or compilation incompatibility. I have checked that vbeset, vbeprobe and testvbe work in grub, so it /doesn't/ seem to be the machine, and it's likely therefore that the issue has to be somewhere in the compiled binaries on the demo diskette. I'm wondering therefore if at some time the sources for vscrtest and its prereqs might be made available? (I will speak to Norman about DoPE). Thanks again. I hope to be back when I have got the next bits working successfully. Kind Regards & thanks all once again. David D
