 Posted: Fri Aug 16, 2002 11:18 am Post subject: Preemptible kernel patch |
 |
|
Probably a question for developers:
I noticed the ppc-sources package (for gentoo 1.2) does not include the preemptible kernel patch. The latest Changelog of this patch mentions PPC support is merged.
I tried this patch manually and everything seems to work perfectly.
Are there any plans for including this patch in the ppc-sources package?

Currently preempt is still pretty unstable. I've been testing preempt on ppc for awhile now, and while things have gotten better they aren't to the point where I'd be happy releasing a preempt'd ppc kernel. One of the things I've noticed is, play MP3s in xmms, compile a kernel, and then switch windows a lot in KDE. You'll get some serious system stuttering.... I've tried the preempt patches against vanilla sources, and benh trees. So it's not for a lack of trying =)

Thanks for the warning,
My system does indeed seem to be a bit less responsive the last days.
I just tried
| Code: | | echo "scale=5000;4*a(1)" | bc -l |
(this calculates pi to 5000 decimals)
This completely freezes my system untill the calculation is done and the load average goes up to 18.
Ha well, it promising technology anyway.
Greetings,
BTW: is there any website/forum/mailinglist where someone can follow these kinds of developments (like what kernel patches are being tried in the ppc kernel) |
