unofficial linux-ck repo with cpu optimized packages is ONLINE

@saran - OK, I added support for silvermont in the gcc patch and have compiled a linux-ck kernel/headers package for you to test on your silvermont Celeron. I will send you a private email with the link. Please install and see if everything works.

That was quick, thank you!

I have just installed kernel and headers, and so far so good. Everything seems perfectly normal.
I'll be using laptop all day, and will report any unusual behaviour.
Is there anything more I can do? Maybe run some benchmark or stress test to confirm stability?

For haswell-ck, can you apply this patch: https://01.org/sites/default/files/disa … rity.patch
This will fix opencl on the igpu. Source: http://lists.freedesktop.org/archives/b … 04005.html

graysky · 2015-03-08 01:20:07

Saran- no need.
Boogerlad- I don't want to just patch out of tree code into the entire repo or AUR without good justification.

Download the GCC patch fresh. It was just updated to include the Silvermont family of processors (I know this because I had to update the ck-pax patch to accomodate this).

Šaran · 2015-03-09 19:20:30

Hi graysky,

Silvermont build is not causing any troubles. I haven't had any issues for the past two days.

OK. I have added silvermont to x86_64 and have built up the package set. You should be able to install via:

# pacman -Syy
# pacman -S ck-silvermont
:: There are 8 members in group ck-silvermont:
:: Repository repo-ck
   1) broadcom-wl-ck-silvermont  2) linux-ck-silvermont  3) linux-ck-silvermont-headers  4) nvidia-304xx-ck-silvermont
   5) nvidia-340xx-ck-silvermont  6) nvidia-ck-silvermont  7) virtualbox-ck-guest-modules-silvermont
   8) virtualbox-ck-host-modules-silvermont

Enter a selection (default=all):

Let me know if there are problems and enjoy!

Thank you very much kind sir!
Installed and already enjoying it.

boogerlad · 2015-03-10 19:02:23

Is it possible to switch the default compression to cat or lz4 for the haswell kernel? My own testing shows that to be the fastest.

graysky · 2015-03-10 19:21:46

You may select whatever compression suites your needed in /etc/mkinitcpio.conf -- the package does not dictate this behavior.

Doesn't /etc/mkinitcpio.conf only affect the initramfs? The kernel itself I checked still seems to be gzipped, regardless of the setting in /etc/mkinitcpio.conf. It should be a kernel option afaik.

graysky · 2015-03-10 19:31:12

Perhaps am I misunderstanding... what default compression are you referring to in this case? The packages?

boogerlad · 2015-03-10 19:33:03

In /boot I have three files. intel-ucode.img which I probably shouldn't touch. initramfs-linux-ck.img which I can tweak slightly with /etc/mkinitcpio.conf. and vmlinuz-linux-ck, the gzipped (by default in kernel options) kernel which I can't really tweak without spending a lot of time and not using this repo.

graysky · 2015-03-10 19:42:42

Ok, I understand now. I never looked at that particular file but I'm sure there's some option in the .config of the kernel that dictates its format based on:

% zgrep -i gzip /proc/config.gz                                                                         :(
CONFIG_HAVE_KERNEL_GZIP=y
CONFIG_KERNEL_GZIP=y
CONFIG_RD_GZIP=y
CONFIG_MODULE_COMPRESS_GZIP=y
CONFIG_DECOMPRESS_GZIP=y

I don't like to depart too far from the default ARCH config in linux-ck. I would recommend that you compile a custom version tweaking that option to suite your needed. You might be able to uncompress that file and recompress it without rebuilding at all. I don't know about this option.

Related question…

Although I have no difficulty, I have specified 'COMPRESSION="lz4"' in /etc/mkinitcpio.conf and this flashes by in boot, here copied from 'journalctl -b' output…

Mar 12 09:57:14 KISE-005 kernel: Initramfs unpacking failed: data corrupted

Curious as to this… .. ?

graysky · 2015-03-12 19:07:50

Not sure... does it boot despite the error? Maybe try regenerating the image and if that fails another compression method... the method of 'cat' is actually the fastest since none is used.

The the one and apparently only indication of the problem is this message.

Of course the initramfs is generated every time linux-ck is updated, and this has been going on for some time, and speed is not really that important on this system.

But I'll change the method to 'cat' and see what happens... .. .

UPDATE:
Regenerated initramfs with & without 'COMPRESSION="lz4"' for the stock archlinux kernel. With lz4 I get the "Initramfs unpacking failed: data corrupted" message, and with "cat" I do not.

Must be some quirk in lz4.

Think I'll switch to "cat".

@graysky: Thank you so much for your repo builds! I've been using them solely on my previous ThinkPad x201s for a couple years now with nary an issue! It's really a time-saver, as i already build all my desktop's mainline kernels.

Just picked up a ThinkPad X1 Carbon 3rd gen w/Broadwell. Looks like your patchset added compiler support back in 3.14.6 for Broadwell, but no linux-ck-broadwell builds yet. Any plans for pre-compiled Broadwell binaries?

Just to confirm - here was the same with a lot of previous linux-ck kernels compressed with lz4. I also tried to put lz4 to mkinitcpio.conf modules. The warning was displayed, but system started normally. With no compression - no "data corrupted" messages.

Šaran · 2015-03-31 15:53:06

I'm using lz4 with "-9" option and there are no warnings on any of my computers,

@graysky
hi.
i want know that what are advantages and disadvantages of linux-ck kernel/headers setup patches?
is there any risks of hardware failure?
i'm using an hp laptop with Intel core i7-2630Qm + 8GB RAM + ATI Radeon HD6770M and lovely arch so which packages will give me a good and acceptable performance boost?
sorry for my bad English (not a native English)

bstaletic · 2015-04-03 09:09:47

Rial Kraesis,

You should install ck-sandybridge group. That is if you want kernel optimized for your cpu.

You can research the advantages yourself by looking at the linux-ck wiki page or this forum thread. As to hardware failure, I don't see how one particular patch set would induce that.

Риал Краесис · 2015-04-04 09:25:31

@bstaletic & Alad
thanx.
i will test it.
sorry, but which one?
1-broadcom-wl-ck-sandybridge
2-linux-ck-sandybridge-headers
3-linux-ck-sandybridge
4-nvidia-304xx-ck-sandybridge
5-nvidia-340xx-ck-sandybridge
6-nvidia-ck-sandybridge
7-virtualbox-ck-guest-modules-sandybridge
8-virtualbox-ck-host-modules-sandybridge
the 4/5/6 are mentioned that they are for nvidia(but i have AMD Radeon)! shall i install them too? just wanna be sure.
personally i think 1/2/3/7/8 should be installed.
