[ACTIVITY] Week 38

[Renato Golin]

== Progress ==

* Trying to profile ImageMagick on A9
 - perf is broken on Exynos 4, used Panda
 - Linaro image doesn't have all PPAs
 - Clang code 10% worse than GCC on some operations
 - Code doesn't look that bad, but Clang on x86 is faster
 - Will look into that next week

Background
 - Meetings at ARM, Linaro
 - Omair in Cambridge
 - Patch review, fixing bots, discussions, etc
 - Moved from Ubuntu to Mint 15, using Gnome Shell

== Plan ==

* Finally look into the profiler output
* Increase the profiling to other image operations
* Profile Phoronix results?

arm-linux-gnueabihf kernel headers out of date?

[Christopher Covington]

Hi,

In building some code (CRIU) that includes linux/if_packet.h for
x86_64-linux-gnu, arm-linux-gnueabihf, and aarch64-linux-gnu, some
discrepancies popped up relating to whether the TPACKET_V3 structures were
defined. It looks like the headers shipped with the 13.08 arm-linux-gnueabihf
toolchain do not define them, implying kernel headers older than October 2012.
The aarch64-linux-gnu toolchain on the other hand does have them defined. If
this analysis is correct, can I expect the kernel headers in the 32-bit
toolchain to be updated in the near future or should I really be generating
and referencing my own kernel headers?

Thanks,
Christopher
