Thanks, I guess I will just wait...

The linux-ck repo needs an update for the virtualbox-modules 4.3.4. -> 4.3.6

Harvey

graysky · 2013-12-20 11:47:17

@Harey - Done. In the future, you can also flag the package out-of-date in the AUR to let me know a newer version is available as well.

enihcam · 2013-12-23 11:15:03

MMX/SSE are disabled in kernel? If so, can linux-ck re-enable them? If cannot, is it still meaningful to maintain multiple CPU versions of linux-ck?

commit fec4a0d9c7b17279553712f9b2da37254edf514e
Author: H. Peter Anvin <hpa@linux.intel.com>
Date:   Mon Dec 9 15:43:38 2013 -0800

    x86, build: Pass in additional -mno-mmx, -mno-sse options
    
    commit 8b3b005d675726e38bc504d2e35a991e55819155 upstream.
    
    In checkin
    
        5551a34e5aea x86-64, build: Always pass in -mno-sse
    
    we unconditionally added -mno-sse to the main build, to keep newer
    compilers from generating SSE instructions from autovectorization.
    However, this did not extend to the special environments
    (arch/x86/boot, arch/x86/boot/compressed, and arch/x86/realmode/rm).
    Add -mno-sse to the compiler command line for these environments, and
    add -mno-mmx to all the environments as well, as we don't want a
    compiler to generate MMX code either.
    
    This patch also removes a $(cc-option) call for -m32, since we have
    long since stopped supporting compilers too old for the -m32 option,
    and in fact hardcode it in other places in the Makefiles.

@enihcam - Not sure I understand the commit log.

lano1106 · 2013-12-23 17:38:17

there must be a good reason for having no MMX and no SSE instructions in the kernel. I would not recommend undo that commit in mainline.

I guess that to use these instructions, you must put the processor in a special state. This state must be saved and restored for context switches. Hence, it is not impossible to use SSE in the kernel but it must be carefully planned. You cannot just let the compiler to randomly pepper the code with SSE and MMX.

graysky · 2013-12-23 19:10:11

@lano - Thanks for the explanation. Enihcam seems to be concerned that this commit would nullify any gcc flags the patch enables. You have any insights there?

sure it can partially nullify any performance boost that you could get with these instruction sets but IMHO, this is a neccessary evil. Not accepting this loss in performance from not using these instructions has the potential to create kernel panics.

That being said, I do not think that targeted platform compilation is just MMX and SSE so you still get benefits from the patch even without SSE and MMX.

The description of the broadcom-wl-ck-bulldozer package is: Broadcom 802.11abgn hybrid Linux networking device driver for linux-ck. AMD Bullzoder optimized.

graysky · 2014-01-08 00:04:43

Fixed for the next build. Thanks.

Harey · 2014-01-14 13:27:59

Hi graysky,

could you please provide the bbswitch kernel module in the ck-repos? My son's new laptop needs it, as it is an optimus design.

Sorry, you will have to install the headers package and build from the AUR. I don't want to maintain more packages in the repo.

Harey · 2014-01-14 15:06:00

OK, I can understand that. I guess the bbswitch-dkms AUR version would be the best choice?
Thank you for your help.

Harvey

WonderWoofy · 2014-01-14 15:25:33

I've never been a huge fan of dkms. I would personally recommend using the more traditional module package.

I use a broadcom wireless card that requires the wl module. I downloaded the srcpackage for broadcom-wl, then after building the thing (and therefore snatching the source) I stuck it in the same directory as the PKGBUILD and modified the source array to look for it there. Then I used 'makepkg -S' to package it up in its own srcpackage for later use. I guess this is probably more necessary since I rely on it for my network connectivity, but knowing that it is always on my machine is comforting.

Harey · 2014-01-14 16:57:48

I also had problems with dkms before (virtualbox modules), so I think I will try to compile with the Arch standard PKGBUILD adapted to my needs. Although the source might change quite often as a part of bumblebee, having it on my computer makes sense to me. Let's see what changes more frequently, the kernel or bbswitch

Thanks for the advice
Harvey

WonderWoofy · 2014-01-14 17:41:18

If the source changes, then it will be like any other AUR package that needs to be updated. I personally use cower which can tell me which packages are in need of updating. If you too use some kind of AUR helper, it should notify you. At that point, then you can download the new srcpackage and then make the same modification the the source array. Then repackage it all up with the sources with 'makepkg -S' and you're good.

@graysky, sorry for the OT.

3.12.8 needs a recompile of the virtualbox modules

That is odd; my test box running 3.12.8-1-ck1 was able to modprobe them just fine. Just bumped the verpkg and building now. Should be online in 5 min.

Harey · 2014-01-18 12:06:11

Installed new pkgver and it's working again - thank you for a reaction fast as lightning

Hi graysky,
I'm new to arch linux, I always used debian sid. I recently decided to try ArchLinux and I was impressed with its cleanliness and speed. I love especially the installation command line. I congratulate you for maintaining ck version of the Linux kernel and make it available to everyone.

I just want to know if you can be able to enable SELinux support in your builds optimized for the processor. If this isn't a problem. We have only to support SELinux and xatr for ext *. I think this is enough for general support.
If you enable SELinux support, I wouldn't need to recompile all packages (broadcom-wl-ck, ck-nvidia, virtualbox-ck etc ...).
I do not know if this will bring great losses of performance.
Thank you.
Sorry if my request has gone OT.

graysky · 2014-02-01 11:10:28

@ptk - Never used it before. The wiki suggests that it should be available in 3.13 and indeed the config files show that it is. I keep the -ck package as close to ARCH as possible so it should be there once CK releases the patchset for the 3.13 tree.

ptk00 · 2014-02-01 11:42:06

Then tnx for flash reply.

Maybe i'm blind but is there any description how to use your modprobed-db and the aur linux-ck package?
I already run modprobed-db and it has stored all that stuff, but now how do i "tell" the pkgfile that it should use this informations. I know that there is
_localmodcfg=
in the pkgfile but what's next?

So sorry for my bad spelling, getting very tired
