Hello,
if you have an R5k O2 please test the kernel image and userland - both
are -current from last night - found here:
ftp://ftp.netbsd.org/pub/NetBSD/misc/macallan/sgimips/
( should work on R10k too but I can't test that )
The difference is that everything ( besides boot64 ) is built with
- -march=mips3 -mtune=r5k - this saves a lot of space and seems to be
substantially faster than the official builds which default to
- -march=mips1
Besides that the kernel contains some changes regarding mace and mec -
the delay()s in bus.c are gone, instead I put them into if_mec.c since
mec seems to be the only hardware that actually needs them - not sure
why though, neither OpenBSD nor Linux seem to need them.
On my machine this is stable so far, mec isn't blazingly fast ( only up
to 3MB/s ) but I don't get spontaneous resets on heavy network traffic
either.
have fun
Michael
