Benchmark automation - TCWG-360 [5/10]
* Flushed the rest of the easy stuff from my 'small fixups' to my
'staging' branch
* Started rolling generic patches from my backport-benchmark branch into gerrit
* Prodded at the prototype backport-benchmark job until the pieces worked
** Ran out of time to try an end-to-end run
* Thought a little about permissions for access to source/results
* Use of nc.traditional appears to have introduced a race condition
catomics - TCWG-436 [2/10]
* Tried a run on A15 - same story as A57, good improvement on g8 libc
ubenchmark that doesn't translate into SPEC subset
* Performance counting the ubenchmark suggests variation around cache
accesses on the catomic vs not-catomic code, didn't have any time to
think about what, if anything, this means
Misc [3/10]
* Featuring an unusual level of ARM interruption
* Especially concerns about change from multiarch to non-multiarch
sysroot in binary releases
=Plan=
Confirm backport benchmarking working, roll remaining generic patches
into gerrit
Investigate the nc.traditional race
Add a retry loop around LAVA boot (occasionally see LAVA-fail here)
Create unit tests
Follow up on (non-)multiarch sysroot issue
