Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Since the latest update, I'm not getting more than ~2 hrs. of battery life out of linux-ck-sandybridge, compared to the previous ~6 hrs. yikes  The wifi interface uses ~ 6 watts of power, while the ethernet interface uses ~13 watts,  and core temps run into nearly 60 degrees celsius (while normally being half that much).  Arch's vanilla kernel does just fine, though. Any thoughts on troubleshooting this?

Hi, I couldn't see if anyone had this problem so far, but I have some trouble using systemd to start user sessions with the ck-bulldozer kernel as it misses the cpu cgroup.

Is it possible that you add this option to the build? ( CONFIG_CGROUP_CPUACCT=y if I'm not mistaken)

So this is why I can never get the user sessions to work! I always thought that I had something configured all wonky that wouldn't allow this.

Thanks for the insight habarnam! I'm going to compile a Cl kernel myself evening get home and test this out!

BTW, thanks for another perfectly working update graysky (linuck-ck-ivybridge).

Can you verify that this is true using the 3.7.6-1 kernel from [testing]?  99 % of the time, these regressions are not due to the ck patchset, but are due to something in upstream.  I would be shocked if this were any different.

You're going to add-back the option that CK specifically disabled???

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

I'm getting a (total) power draw of approx. 9-10 W on battery with 3.7.6-1-ck, which is about how it's always been for me, so no problems here… hmm

Yeah, I figure it is worth a try, as I always enjoy tinkering.  My thoughts are that since you so graciously offer us a repo with such an awesome selection of optimized kernels, switching back will be no problem.  Also, I figure that since it is actually enabled in the official's repo, maybe it is something that will be of no consequence either way?  I really have no idea, but I have been wondering for quite some time why I cannot for the life of me get user sessions to work.  So if this fixes it, great, if not, well I'll be back to repo-ck.

Edit: Okay, better idea... I am going to try with the normal kernel first, then if that works, then I will try modifying the ck config.  I figure I should make sure that it works with the stock kernel before assuming that its inability to function correctly is caused by the kernel.

Edit2: Okay I have confirmed that user sessions work just fine on the official kernel. Though graysky, I am curious if you know of any specific reasoning why this configuration might have been disabled intentionally by ck? I have yet to get to actually testing a modified kernel, but you certainly know more about this patchset than I, so I'm just curious.

Is your boot faster if you disable BFQ? If so, just remember that BFQ focuses more on responsiveness rather than disk throughput.

Okay, so I cannot turn on CONFIG_CGROUP_CPUACCT without turning off BFS... and that does not seem worthwhile.

For repo users, BFQ is just a module like any other.  It is therefore not enabled until the user enables it.  Do this:

1) boot into the ck kernel and post the output of 'systemd-analyze'
2) boot into the ck kernel and do the same

Checking this now.  I'm actually on battery power right now with linux-3.7.5, and the power drain exists there as well.  Not sure what conditions gave me extra juice yesterday.  I'll edit this post to let you know shortly.

EDIT: 3.7.6-1 seems to be doing fine.;  I'm looking at ~2 hrs. on 34% charge.

To anyone who is not aware of this. The way to do this, is to add linux-ck-sandybridge-headers (or w/e version you use) to the SyncFirst option in pacman.conf.

@moscar - Interesting... but why is this not needed for the official kernel?  In other words, what controls this order for it?

I use the catalyst-hook package, which adds linux-headers to SyncFirst. I was not aware of this when I asked about this some days ago. So it is needed for every kernel wink

I have this line in pacman.conf:

SyncFirst = pacman linux-headers linux-ck-sandybridge-headers

Hey Graysky, if you don't mind it would be nice if you could build the Piledriver ck-kernel. But if I am the only person who needs/wants it I can also use the generic package.

kernel 3.7.8-1-{ARCH,ck} with laptop-mode-tools fail to restore from suspend some keyboard/mouse input until <CTRL+ALT+BACKSPACE>

As a workaround uninstall laptop-mode-tools.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

@ontobelli - Since the problem affects both the ARCH and ck kernel, it is not a function of the ck patchset.  Plz don't report such things to this thread since it is only for repo related discussion.

Re: unofficial linux-ck repo with cpu optimized packages is ONLINE

Hi Graysky,

I am using your linux-ck-atom build and I just noticed that CONFIG_X86_GENERIC was enabled which has the following effect to the compilation:

Makefile_32.cpu:cflags-$(CONFIG_X86_GENERIC)    += $(call tune,generic,$(call tune,i686))

IMO, this might slightly defeat the purpose of having very targeted binaries. All 32 bits targets are possibly affected by that....
