unofficial linux-ck repo with cpu optimized packages is ONLINE

ronnylov · 2015-10-28 16:56:26

Hi!

I have bought myself a new intel NUC5CPYH computer with an intel N3050 CPU in the Braswell family. Is this CPU supported by repo-ck and if so which package should be used?

Edit: I found that Braswell belongs to the Airmont family which is the 14 nm die shrink of silvermont so my guess is that I can use ck-silvermont?

Have you read this? https://wiki.archlinux.org/index.php/Re … ed_package

@ronnylov - What is the output of the following on that machine:

gcc -c -Q -march=native --help=target | grep march

Hi graysky, thanks for your work.

Would it be possible to add bdver3 (AMD Steamroller 15h family 30h-3fh models) to repo-ck?

The output is:

[ronny@nuc ~]$ gcc -c -Q -march=native --help=target | grep march
  -march=                               silvermont

So the answer of my question is silvermont.

@kevin and ronny - At this point, I really don't want to package up any additional architectures for the repo. You are welcome to build your own. Currently, silvermont is an option in the gcc_patch but bdver3 is not. I can add it, kevin if you post the output of that same command.

Hello graysky, the output of the command follows:

[test@test ~]$ gcc -c -Q -march=native --help=target | grep march
  -march=                               bdver3

Thanks kindly for your reply.

graysky · 2015-11-02 21:54:24

OK. I updated the patch for this CPU. I can build linux-ck just fine using the new option for this CPU but since I do not have one, I need you to test a kernel built with this option enabled. Would you please build and test it? Link to download it.

Currently building, will reply when it is built / tested.

Cheers.

Compiled / works fine, I left everything default except the patch.

Will recompile with bfq / _makenconfig=y / etc.

Thanks!

Hi graysky

Can you help me understand why linux-ck isn't on 4.2.x yet? What is the process and timeline for patching the kernel with BFS and BFQ?

CK needs to port ck1/bfs over from 4.1 which hasn't yet happened. Nothing we can do until that happens. Hopefully, the 4.3 port will be forthcoming.

Oh. Yea, hopefully

If I wanted to build the kernel from AUR instead of using the prebuilt ones from your repo, how would I go about optimizing it for my core2duo like you have done?

For the kernel, it's more complicated: https://wiki.archlinux.org/index.php/Re … d_packages

OK. I have been running 4.3.0-1-ck for 3 days without a problem and none were reported by early adopters so I refreshed the repo. The only gotcha is there are currently no broadcom-wl-ck for i686 due to a build failure. I need someone with more knowledge to look it. See the AUR page for details.

EDIT: Apparently, nvidia-304xx-ck isn't working either under i686:

% sudo modprobe nvidia              
modprobe: ERROR: could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg)

...

[  382.526033] nvidia: Unknown symbol mtrr_del (err 0)
[  382.526299] nvidia: Unknown symbol mtrr_add (err 0)

Unfortunately, it isn't working under x64 either, I can't get the Xorg server to start. Got exactly this error in dmesg. Switched to the Arch default kernel.

Is there a way to fix this nvidia bug or do we have to wait until nvidia fixes it?

graysky · 2015-11-17 09:41:33

It's an upstream bug that is not unique to the ck flavors. Happens under the official kernel as well.

eschwartz · 2015-11-18 05:27:44

linux 4.3 seems to have problems with intel chipsets -- maybe just old ones?

https://bugs.archlinux.org/task/46968

Upgraded linux-ck on my old Dell Inspiron B130, and the display was totally messed up.

graysky · 2015-11-18 11:50:25

Thanks for the link to the FS. My testing on modern and somewhat modern hardware do not reproduce. I asked the OP to report it upstream:

Using linux from ABS (4.3-1 with a few custom settings in the .config) works fine on the following hardware as does the corresponding linux-ck (4.3-1). Note I do not have [testing] enabled:
*Broadwell i7-4790K that uses HD Graphics 4600
*Haswell i3-4130T that uses HD Graphics 4400
*Ivy i7-3770K that uses HD Graphics 4000

I don't have anything older I can test on.

eschwartz · 2015-11-18 18:18:06

You're welcome.

It looks like there is a patch to fix it:
https://bugs.freedesktop.org/show_bug.cgi?id=92655
http://lists.freedesktop.org/archives/i … 79894.html

But for the life of me I can't figure out how to get at the patch without having been retroactively subscribed to the mailing list

EDIT: NVM, here's the diff at least: https://bugs.freedesktop.org/attachment.cgi?id=119541
