Hello out there,
tried to build Kernel 2.6.0-test6-bk4 on my
sparc32 machine and found that the function
sched_clock is missing in time.c. Can anyone
tell me what I have to put there? Please CC
to me.
Thanks in advance

This is the minimal version to get you going.
A better implementation would use a higer-resolution counter, if the
hardware has such a thing.

Thanks a lot, I can compile and boot the kernel now.
But still the keyboard does not work...
