Sick Leave [4/10]
== Plan ==
QEMU kernel debugging setup [TCWG-568]
-- Figure out steps to debug kernel with ARM cortex A15 core.
More Kernel debugging to investigate limitation of ARM watchpoint
implementation [TCWG-569]
-- Get A15 core running on QEMU and debug kernel hw debug
implementation on both A9 and A15.
Updates to GDB wiki pages with kernel debugging howto.
I've completed renaming Cbuildv2 to Abe, as well as modifying all the
board files for remote testing to match what the new DNS server is
using. Please stop using the existing cbuild2 repository, as all changes
are now done in the new repository. I'll leave the old repository for a
while, I know there are branches there people depend on. For those, I'm
sorry for the pain (having just gone through that myself), but please
migrate any important branches to the new repository. URLs for that are
here:

ABE benchmarking - TCWG-360 [7/10]
* Finished post-move LAVA lab workarounds
* Should be flexible enough for TCWG lab too, but we'll see
* Refactored sources - now more robust and maintainable
lowlevellock.h comments - CARD-341 [1/10]
* A further round of changes, got an OK
Raised a bug on GCC re questionable generation of pow calls - TCWG-558 [0/10]
* Upstream fixed it really fast
Misc - [2/10]
=Plan=
Switch to TCWG Junos, perhaps start using gprof
Think about where to go next with libm exercising
Look though Will's single-thread performance patches
Test benchmark repeatability
Port benchmarking scripts to ABE repo
Start on storage/automation, if Rob has time
