Hey, thanks for the response and the offer to keep me posted on the problem :)
Last time I tried with QEMU the system was working perfectly fine (with "make qemu"). Unfortunately, I need to run it on a real machine to get some performance measurements.
Use grub1 is a quick tip, possibly via netboot (pxegrub). A short look at current grub2 shows me some interesting and likely changed behaviour but I didn't check further right now.
Oh! I forgot to add that everything but the serial console works. I suppose I'll have to manually copy any timing numbers I print from my experiments.
Just in case, here's my grub1 entry:
title L4 (original) root (hd1,0) kernel /l4-orig/bootstrap -serial module /l4-orig/fiasco -serial_esc -comspeed 115200 -comport 0 module /l4-orig/l4f/sigma0 module /l4-orig/l4f/moe --init=rom/hello module /l4-orig/l4f/l4re module /l4-orig/l4f/hello
That looks ok and should just work. Does it work under Qemu? Is it a plain normal serial? Is it working in Grub?
It works flawlessly under QEMU. The Grub menu also shows up on the serial console of the real machine, but once bootstrap is started, only the screen works.
That all looks good to me, and that it works in Qemu also indicates that it's ok. Could you maybe try another machine to see if it works there?
