unofficial linux-ck repo with cpu optimized packages is ONLINE

karol · 2014-10-28 16:10:33

Maybe https://wiki.archlinux.org/index.php/Li … _Scheduler should be made a bit more clear. As it is, my thought process would be the same as czubek's.

czubek · 2014-10-28 21:30:41

Based on the help provided by clfarron I tried to enhance the "linux-ck" wiki with some clarifications. Unfortunately, even trying to edit the "discussion" became overwhelming. For what it's worth the following is my meager contribution:

3 How to enable the BFQ I/O Scheduler

Budget Fair Queueing is a disk scheduler which allows each process/thread to be assigned a portion of the disk throughput.

Since version 3.0.4-2, the BFQ patchset is incorporated into the package by default. Unless enabled the scheduler will default to CFQ. The scheduler can be enabled either Globally (for all devices), or Selectively, (for specified devices).

Global Application

If compiling from the AUR, simply set the BFQ flag to yes in the PKGBUILD prior to building.

_BFQ_enable_="y"

This will enable the BFQ scheduler for this kernel version every time it is booted. If the kernel is upgraded with a new version , the BFQ flag for the new kernel must be set to "y" to enable BFQ.

If one makes use of the pre-compiled ck kernels then BFQ can be enabled by appending the following to the bootloader's kernel parameters. An example using syslinux would look like:

LABEL arch-ck
    MENU LABEL Arch Linux-ck
    LINUX ../vmlinuz-linux-ck
    INITRD ../intel-ucode.img,../initramfs-linux-ck.img
    APPEND root=/dev/sda3 rw elevator=bfq

Selective Application

An alternative method is to direct the kernel to use it on a device-by-device basis. For example, to enable it for /dev/sda simply:

# echo bfq > /sys/block/sda/queue/scheduler

To confirm:

# cat /sys/block/sda/queue/scheduler
noop deadline cfq [bfq]

Note that doing it this way will not survive a reboot. To make the change automatically at the next system boot, create the following tmpfile where sdX is the desired device:

/etc/tmpfiles.d/set_IO_scheduler.conf
-------------------------------------------------------------------
w /sys/block/sdX/queue/scheduler - - - - bfq

...how is that fundamentally different that this wiki section: https://wiki.archlinux.org/index.php/Li … _Scheduler

karol · 2014-10-28 22:31:10

How about https://wiki.archlinux.org/index.php?ti … did=332882 ?

czubek · 2014-10-28 22:58:14

@graysky. From the wiki I got the impression that both the pkgbuild flag and the elevator statement must be done in order to enable BFQ. I found out that it was either or. I probably went overboard in my suggested changes, but they are only suggestions and now that I understand it is ok with me if they are discarded.

I recommend karol's revisions. They are far more concise.

Already implemented in 3.16.6-3, see the changelog: https://wiki.archlinux.org/index.php/Linux-ck/Changelog... live in the repo a few moments ago.

I have 3.16.6-3, but the microcode update did something wrong anyway.
If I boot with

initrd  /boot/intel-ucode.img   /boot/initramfs-linux-ck.img

I still get kernel panic. .img file exists and is there. Booting without the ucode file works fine. What's wrong? Hardware in sig.

karol · 2014-10-29 08:41:59

Are you using BURG? Did you generate a new burg.cfg?

Yes, using BURG and no, I just inserted "/boot/intel-ucode.img" in the .cfg as the wiki suggests to do (for GRUB).
I'm not sure this is the right place to discuss this, I don't know if it's a kernel problem or not. I'll try another kernel when I get time. Maybe it's BURG's fault?

graysky · 2014-10-29 10:01:57

Must be something in berg... works just fine on booting with grub 1:2.02.beta2-4:

Works for me (syslinux, 32-bit Arch).

Must be something in BURG, just checked and it does not work with vanilla either. That's very weird.

Nordic89 · 2014-11-02 07:23:41

Do the kernels support tomoyo?

graysky · 2014-11-02 08:05:21

No, but neither does the official ARCH kernel:

% zgrep -i tomoyo /proc/config.gz
# CONFIG_SECURITY_TOMOYO is not set

IIRC, support was removed from the configs in the 3.14 series of kernels in ArchLinux (when they had the massive config cleanup).

@PG - Are you using the repo package for linux-ck? If so you should also be using the nvidia-ck package from the repo too. I do not provide the r8168-ck package so as long as you have the repo linux-ck-headers pacakge, you can build up whatever you want from the AUR.

Hi @graysky, I believe this is not the first time to ask you this favor. Sorry about my bad English. Could you please bring r8168-ck package into the repository? I asked this again really because 90% motherboards out there are integrated with realtek chips (larger than Broadcom and NVidia chips), and there are many people don't want to use AUR (many use archlinux for building router or NAS), so they are struggling in decision of using Linux-ck or not.

People like you and appreciate your works in these years. The r8168 module from realtek.com doesn't release very often, and I believe for you it take little maintenance effort to avoid hundreds or thousands of people installing AUR. I don't know why other people use archlinux, but for me the biggest reason is archlinux has repo-ck and great contributors like you. If you release r8168-ck, more people will switch from other distro to archlinux, therefore strengthen this community and I'm sure you will have returns more or less.

I tried my best to express my thoughts, but let me know if you misunderstood any sentence.

Thanks,
Enih

Why exactly not use AUR or set up your own repository?

For me I guess I want to keep my x86-64 router KISS as possible.

graysky · 2014-11-11 09:50:16

Sorry, as I have said in the past, I do not have hardware to test the built packages and I really don't want to expand the offerings beyond these core packages for mataiance reasons. You will need to rebuild it manually.. Perhaps write a dkms package?

graysky · 2014-11-11 22:25:56

OK 3.17.2-1-ck is in the AUR along with accompanying packages. I might not be able to update the repo until this time tomorrow. Very busy tonight and I don't like rushing or automating major version bumps. Just FYI.

graysky · 2014-11-12 10:55:35

Build and tested. Repo populated. Enjoy.

Kaan · 2014-11-12 11:53:08

Nvidia packages needs to be updated now, "nvidia-340xx-ck-core2: requires nvidia-340xx-utils=340.46"

graysky · 2014-11-12 15:08:10

Yes, 340.58 recently hit [extra]. I will build later this afternoon,

Hi, I'm using the linux-ck-nehalem and nvidia-ck-nehalem packages from the binary repo on my 64-bit desktop machine. Even though pacman says my system is up-to-date, I'm still running linux 3.16.7:

$ pacman -Q linux-ck-nehalem                                                       
linux-ck-nehalem 3.16.7-1
$ uname -r
3.16.7-1-ck

The nvidia driver package is also outdated on my system

$ pacman -Q nvidia-ck-nehalem                                                      
nvidia-ck-nehalem 343.22-4

I tried downloading the packages from the web site manually, but the signature verification for linux-ck-nehalem fails

$ pacman-key -v linux-ck-nehalem-3.17.2-1-x86_64.pkg.tar.xz.sig 
==> Checking linux-ck-nehalem-3.17.2-1-x86_64.pkg.tar.xz.sig ...
gpg: Signature made mer 12 nov 2014 00:11:13 CET using RSA key ID 5EE46C4C
gpg: NOTA: il trustdb non è scrivibile
gpg: BAD signature from "graysky (used to sign repo-ck packages) <graysky@archlinux.us>" [full]

Any help?
Thanks

Do you have a separate boot partition? Was it mounted when you did the update?
