@feilen - it's both. Look at line 173.

@graysky - Is it KCCPFLAGS or KCPPFLAGS? In the PKGBUILD it's KCPPFLAGS.

graysky commented on 2011-08-19 15:21 (UTC)

@misc - Right. The stock kernel PKGBUILD is compiled on a generic setup meant for generic i686 or x86_64 wheresa users of the AUR are likely not planning to make a generic package, but likely one for their hardware (particularly if march=native is used in the /etc/makepkg.conf). These flags are not the CFLAGS/CXXFLAGS defined in /etc/makepkg,conf rather, they are the KCFLAGS and KCCPFLAGS which are used in the compilation of the kernel. It is my understanding that with gcc >4.5 these are specific to the machine being used and will provide optimized code for said machine.

Why would you change the flags at that point? The stock kernel pkgbuild merely has ${MAKEFLAGS} for the first and nothing for the second line.

Right, you can only switch I/O scheduler on the fly.

Zom commented on 2011-08-18 23:51 (UTC)

@karabaja4: No. Switching the scheduler requires a recompile.

karabaja4 commented on 2011-08-18 22:29 (UTC)

Is it possible (unlikely, but I'm shooting blind here) to switch between BFS and CFS on the fly while running this kernel?

Update to linux-ck-3.0.3-2 What's different? See lines 173 and 196. Added the following into the make step for bzImage modules modules_install: KCFLAGS="-march=native -O2 -pipe" KCPPFLAGS="-march=native -O2 -pipe" It is my understanding that this will impart CPU-specific optimization in the kernel.
