Details
The repo contains generic packages as well as CPU-specific packages. Many ARCH users are familiar with the concept of a generic kernel package. The official ARCH kernel is available in two flavors (either i686 or x86_64) which are generic packages in that i686 will work with any compatible x86 CPU and x86_64 will work with any compatible x86_64 CPU.
Users have a choice between the corresponding generic linux-ck packages or CPU-specific and optimized linux-ck packages:
GENERIC
- ck-generic ==> Compiled with generic optimizations suitable for any compatible CPU just like the official ARCH linux package. This is true for both Intel and AMD processors.
CPU SPECIFIC AND OPTIMIZED
- ck-atom ==> Intel Atom platform specific optimizations. Intel Atom CPUs have an in-order pipelining architecture and thus can benefit from accordingly optimized code.
- ck-core2 ==> Intel Core 2-family including Dual and Quads (Core 2/Newer Xeon/Mobile Celeron based on Core2).
- ck-nehalem ===> Intel 1st Generation Core i3/i5/i7-family specific optimizations.
- ck-sandybridge ==> Intel 2nd Generation Core i3/i5/i7-family specific optimizations.
- ck-ivybridge ==> Intel 3rd Generation Core i3/i5/i7-family specific optimizations.
- ck-p4 ==> Intel Pentium-4 specific optimizations (P4/P4-based Celeron/Pentium-4 M/Older Xeon).
- ck-pentm ==> Intel Pentium-M specific optimizations (Pentium-M notebook chips/not Pentium-4 M).
- ck-kx ==> AMD K7 (Athlon/Athlon XP)/K8 (Athlon 64, Athlon 64 X2, 23xx Quad-Core Barcelona, Sempron, Sempron 64)/K10-family (Athlon X2 7x50, Phenom X3/X4, Phenom II, Athlon II X2/X3/X4, Sempron 64 [Socket AM3 only], 61xx Eight-Core Magny-Cours) specific optimizations. Enables use of some extended instructions, and passes appropriate optimization flags to GCC.
- ck-barcelona ==> AMD Barcelona CPUs.
- Bulldozer ==> Optimized packages for AMD Bulldozer CPUs.
- Piledriver ==> Optimized packages for AMD Piledriver CPUs.
CPU-specific optimization are invoked at compilation by selecting the corresponding option under Processor type and features>Processor family or by setting-up the .config file accordingly. These changes setup make specific gcc options including the $CFLAGS.
[Graysky's public key] used for package signing. Pacman v4 will automatically query the public key server, but if users would rather download and manually add the key, do so from the link.
Setup
1) Add the following to /etc/pacman.conf
(I placed my entry at the bottom of the file):
[repo-ck] SigLevel = PackageRequired Server = http://repo-ck.com/$arch
To sign graysky's key, do the following:
# pacman-key -r 6176ED4B # pacman-key --lsign-key 6176ED4B
2) Refresh via pacman -Syy
That's it. To see the contents of the repo, just search as such:
$ pacman -Sl repo-ck
Installation Examples
Use the ck-X group and select the desired packages for installation. There are 6 groups corresponding to the 12 package sets: ck-generic, ck-atom, ck-core2, ck-nehalem, ck-sandybridge, ck-ivybridge, ck-p4, ck-pentm, ck-kx, ck-barcelona, ck-bulldozer, ck-piledriver
# pacman -S ck-generic :: There are 7 members in group ck-generic: :: Repository repo-ck 1) broadcom-wl-ck 2) linux-ck 3) linux-ck-headers 4) nvidia-304xx-ck 5) nvidia-ck 6) virtualbox-ck-guest-modules 7) virtualbox-ck-host-modules Enter a selection (default=all):
Alternatively, simply direct pacman to install the packages directly:

How to Enable the BFQ I/O Scheduler
Since release 3.0.4-2, the BFQ patchset is applied to the package by default. Users must enable the BFQ scheduler to use it; it is dormant by default.
Globally (for all devices)
Add elevator=bfq
to boot loader Kernel parameters.
Selectively (for only specified devices)
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, simply cat the same file:
# cat /sys/block/sda/queue/scheduler noop deadline cfq [bfq]
Setting this way will not survive a reboot. To make the change automatically at the next system boot, create the following tmpfile where "X" is the letter for the SSD device.
/etc/tmpfiles.d/set_IO_scheduler.conf
w /sys/block/sdX/queue/scheduler - - - - noop
Package Trivia/Repo Statistics
- Various package sets are compiled via a Bash wrapper script for makepkg. The script is publicly accessible at graysky's github repo.
- Repo statistics are available (popularity of packages, which CPU is most popular, # of downloads, etc.).

Forum Support
Please use this discussion thread to voice comments, questions, suggestions, requests, etc. Note from graysky, "I can add other CPU-specific builds upon request. I just wanna be sure people will actually use them if I take the time to compile them."
