[ACTIVITY] (Dave Martin) week 24 2011 (2011-06-13 - 2011-06-17)

[Dave Martin]

== Dave Martin <dmart> ==

=== General Activity ===
 * Some kernel patch work:

    * CPU info declaration macros -- A conclusion seems to have
      been reached on the form these should take.  Some
      implementation work done; still need to finish, test and
      post.

      This should permit a fair number of lines to be removed
      from arch/arm/mm, without any functionality impact.

    * Will Deacon's Generic MMU off code -- helped fix an off-
      by-one type bug which was preventing the temporary
      stack's identity mapping from being installed properly.

* More activity on minor bugs in gas:
 * http://sourceware.org/bugzilla/show_bug.cgi?id=12854 (ARM:
   Nonsensical argument shift specifications accepted for
   LSL/LSR/ASR/ROR mnemonics)

* Tracking down some userspace alignment faults:

 * gtk-sharp2 -- https://bugs.launchpad.net/ubuntu/+source/gtk-
   sharp2/+bug/798315

 * firefox --
   https://bugzilla.mozilla.org/show_bug.cgi?id=626635 (already
   reported and fixed by other people upstream; fixed in 5.0 /
   oneiric)

 * Started a mail thread about whether we should be more
   aggressive in getting alignment faults fixed, particularly
   within Linaro.

=== linaro-kernel-o-standard-arch ===

 * Testing  of  the  linux-linaro-2.6.39 and linux-linaro-oneiric
   trees with Thumb-2:

    * Pinged John Rigby again -- he's agreed to  try  turning  on
      Thumb-2 for the vexpress packaged kernel.
    * mx51evk status still to be determined

 * Did  some  investigation  into  what mx51evk is using FIQ for.
   Some compatibility issues for Thumb-2: still need to follow up
   with the the imx guys.

=== Plans ===

 * Check  whether the new kernel trees work in Thumb-2 on mx51evk
   and follow up with Freescale landing team.

 * Follow up on Cortex-A15 model/platform availability.
