[ACTIVITY] week 26 2011 (2011-06-27 - 2011-07-01)

== Dave Martin <dmart> ==

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

    * CPU info declaration macros -- No dissent upstream.
      These patches are now sitting in Will Deacon's tree
      waiting for him to send a pull request to Russell.

    * 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=12931 (ARM:
   gas fails to set the proper alignment on code sections,
   causing broken output)

   This is the issue which is contributing to the WebM codec
   failures in Firefox on ARM.

   Simple workaround proposed and merged upstream.

 * http://sourceware.org/bugzilla/show_bug.cgi?id=12848 (ARM:
   Thumb-2: Range check on b.w is off by a factor of 2)

   This issue is actually affecting virtually all branches in
   Thumb, including BL.

   Tidy-up/fix proposed upstream.

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

 * Started an experimental merge of Catalin  Marinas'  LPAE  (ARM
   Large   Physical   Address   Extension)  patches  with  linux-
   linaro-2.6.39.

   I now have a booting kernel on the ARM  VExpress-CA15x4  model
   making  use  of  physical  memory beyond 4GB, but still having
   problems with SMP (probably a separate issue from LPAE  /  A15
   support).

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

 * Try merging the basic A15 / VExpress new  memory  map  support
   from the AEL tree with linux-linaro-2.6.39 (i.e., no LPAE sup-
   port).  These are likely to merge upstream sooner  than  LPAE,
   and may make sense in the linaro tree.

 * Follow up on Cortex-A15 FPGA platform availability.

 * Suggest  we  disable  aligment fixups for linaro images, since
   gtk-sharp2 is now the only thing known to be affected.
