Official thread: "zen-sources" - Part III

[AYBABTU]

@AYBABTU: Actually, there is a patch few pages before this http://forums.gentoo.org/viewtopic-p-50 ... ml#5065179
that works for me, but it seems nobody noticed it
You need to install driver manually though, or write a new ebuild. Thank you sarah.a.happy

Thanks a lot

[kernelOfTruth]

What ARCH are you using? I've been getting hardlocks on my amd64 system but not on my (old) 32-bit laptop.Swap prefetching enabled and group scheduling disabled on both systems.Tried with both RCU options on and off but makes no difference.
I don't need swap prefetching as much on my amd64 system, so I'll give it a try.

BTW master-devel works fine.

~amd64, gcc-4.2.3 hardened,

I noticed, too, that master-devel works (~2.6.25-zen0), have been using that for a while before .25-zen1 got stable , I'm wondering what was changed in the ck-patchset between 2.6.25-zen0 and -zen1


another WARNING:

don't use

Code: Select all

-falign-functions=0 -falign-jumps=0 -falign-labels=0 -falign-loops=0

in your custom cflags [for the kernel] (in a stable environment) since that might lead to instability

if you're adventurous, try it & please post results / experience reports - you have been warned

2.6.26-rc1-zen0 is available in the new repo for those who want to test that, its running nice on my box

what about linux-phc? it seems it's not included in 2.6.25-zen1

ditto. otherwise the git of zen1 I pulled is the best yet. No hardlocks and my laptop sleeps correctly too. 2.6.24 was a little buggy with random hardlocks.

yeah that is tuxonice, i reverted that patch merge, pull again and it should build fine

i was gonna merge PHC but I coudlnt really tell what was useful these days since speedstep-centrino is depricated....

the cpufreq-acpi patch applied with out a hitch but I think most of the goodies are in the other patches, if anyone knows more about PHC fill me in please

Is there some delay between public/dev repo, or did something go wrong?

Code: Select all

there shouldn't be, i got the exact same error after i merged the tuxonice branch into master and i reverted it asap cause I didnt feel like fixing things,

do a 'git fetch' first, maybe that will help

EDIT: shit maybe I didnt push it .... check in 10 min

[rmh3093]

yep forgot to push the revert... it should be good now

Ah, now it compiled.

But oh well, nvidia again.. when will those bastards finally opensource that damn freaking driver or move it into usespace completely...
patched ebuild here, if someone likes: http://gimpel.ath.cx/svn/gimpel/x11-dri ... a-drivers/

you got nvidia working with 2.6.26-rc1?

Well, "working" yes. "working" in means of: it compiles, it loads, it runs.... thanks to that patch from nv forums (there is a patch to make it work with 2.6.25-mm1, the compile error was the same, so the patch makes it compile and load on .26 too).

But you can count pixels when moving things in compiz. So opengl performance is totally screwed. Non accelerated desktop works fine.
Tried both PAT and good ol' MTRR.

Other than nvidia, the kernel seems to run quite well, including ricer4.

I don't really know what is userful, but it would be really nice to have it again. For me 2.2.35-zen1 also works well, no lookups yet and even tuxonice works

addon:
Found a patch for 2.6.25:
http://phc.athousandnights.de/forum/viewtopic.php?t=52
didn't try yet

addon2:

Just tried. The file linux-phc-kernel-vanilla-2.6.25-teknohog.patch in the mentioned thread is the only one needed and applies cleanly against 2.6.25-zen1. You don't need to have speedstep-centrino enabled, at least for T7200. ACPI_CPUFREQ is sufficient.

My working CPU Frequency scaling config section follows:

[*] CPU Frequency scaling
[*] Enable CPUfreq debugging
<*> CPU frequency translation statistics
[*] CPU frequency translation statistics details
Default CPUFreq governor (ondemand) --->
-*- 'performance' governor
<*> 'powersave' governor
<*> 'userspace' governor for userspace frequency scaling
<*> 'ondemand' cpufreq policy governor
<*> 'conservative' cpufreq governor
*** CPUFreq processor drivers ***
<*> ACPI Processor P-States driver
< > AMD Opteron/Athlon64 PowerNow!
< > Intel Enhanced SpeedStep (deprecated)
< > Intel Pentium 4 clock modulation
*** shared options ***
[*] /proc/acpi/processor/../performance interface (deprecated)


Hope this information is of some help

OK, new somewhat semi-official nvidia patch from Zander.
http://www.nvnews.net/vbulletin/showpos ... stcount=35

Let's test.

EDIT: Bingo!

i use it for the undervolting capability. it makes a huge difference on my laptop; my fan doesn't spin up anymore! because it stays so cool undervolted.

i know what PHC is for, and why you all want it, i just want more details on which patches still work with new kernels, from my understanding most people should be using the cpufreq-acpi driver, when I looked at the PHC code last it seemed like the "PHC" code was all in the speedstep-centrino patch, if i just apply the cpufreq-acpi driver it does not look like it will work... also I have no way of testing that anything is working because last I knew, the coreduo's still weren't supported properly

tranquilcool, the patch is 1:1 taken from Zander's post in nvnews forums, and works fine here. Are you on x86 maybe?

Anyways, you should post on the nvidia forums, see link above.
