# Progress #
* TCWG-517, GDB AAarch64 record/replay. Ongoing. [3/10]
Takes over from Omair, complete test cases and update patches.
Rewrite the test case using gcc inline assembly.
Happen to see that AAarch64 doesn't have CPSR register but
GDB thinks it has. This should be fixed separately later.
* Think about GDB version in next linaro toolchain release. [3/10]
The next linaro release is on July/Aug and the next GDB FSF release
7.10 will be on mid of June. I prefer to picking up 7.10, but need
Ryan or Maxim to make a decision.
* Exchange emails with Peter to push GDB kernel awareness work forward,
and think about how do that in next step. [1/10]
* Misc [3/10]
** Print and photocopy documents needed for France visa application.
# Plan #
* Go to France Embassy in London on Monday.
* GDB AAarch64 record/replay test and upstream submission.

Hi,
I tried on abe 'stable' branch and with below configuration build was
successful.
../abe/configure --with-fileserver=148.251.136.42 --with-remote-snapshots=
http://148.251.136.42/snapshots-ref
../abe/abe.sh --target aarch64-linux-gnu --build all
(Additionally I had to increase the wget_timeout=100)
But on master branch, with below commands (as suggested in above mail)
following error were observed.
../abe/configure --with-fileserver=148.251.136.42
--with-remote-snapshots=/snapshots-ref
../abe/abe.sh --target aarch64-linux-gnu --build all
ERROR (#144): fetch_http (md5sums doesn't exist and you disabled updating.)
Looks like following commit is causing problem on the abe master branch.
On removing it, build successfully downloaded the packages from
148.251.136.42.
commit 5a5ab3582851d52d903846d34c79850f5d7ebda5
don't try to fetch anything is updates are disabled.
Thanks
Virendra

Hi Guys,
I have two questions:
(1) I have download gcc-4.9 tool chain from
http://releases.linaro.org/14.08/components/toolchain/binaries.
The kernel for the release
(http://releases.linaro.org/14.08/components/kernel/linux-linaro) is
3.16. So can we assume the kernel headers found in the tool chain
installation from the link above belongs to linux version 3.16?
(2) Also, I ubuntu wiki indicates that starting with Ubuntu 12.04 they
are using linaro gcc packages for arm64
(https://wiki.ubuntu.com/ToolChain). Is there an easy way to find what
linaro-release (for tool chain) will be compatible with Ubuntu 14.10
aarch64 image?
Thanks,
Aravind

https://registry.hub.docker.com/u/mickaelguene/arm64-debian/
== Plan ==
- Short week (off Thu, and Fri)
- Continue upstream pending work
(Public) Holiday [2/10]
Benchmark automation - TCWG-360 [6/10]
* More unit tests
* Refactoring - test writing is an effective spotlight
* Experimented with LAVA log streaming as a 'listener' replacement
** Reduces complexity, for (possibly insignificant) costs in
generality and scalability
* Gave some thought to results storage, benchmarking of restricted targets
Misc [2/10]
=Plan=
Pick a direction on streaming vs listeners, write down the reasoning
Follow up (close out?) results storages and restricted targets
Write more tests, refactoring where appropriate
Holiday [2/10]
Benchmark automation - TCWG-360 [5/10]
* Finished rolling backbench patches into review
* Submitted some test suite patches to reduce the number of untested cases
* Began writing tests for benchmarking in general
Misc [3/10]
