[Qemu-devel] [PATCH v2 0/4] A number of Travis CI tweaks

[Alex Bennée]

Hi,

The patches I posted last week have been reviewed and I've given them
a good test on my tree. My last test failed but only because master
has introduced a regression. This was found by the tests in master but
missed due to the noise of GTester hangs which are mitigated by
reducing the times we run "make check" in this patch series.

Please apply to the trivial tree so we can get the master branch
testing a little less noisy soon ;-)

Alex Bennée (4):
  .travis.yml: add more linux-user to the build matrix
  .travis.yml: make the make slightly more parallel
  .travis.yml: pre-seed sub-modules for speed
  .travis.yml: remove "make check" from main matrix

[Qemu-devel] [PATCH v2 1/4] .travis.yml: add more linux-user to the build matrix

[Alex Bennée]

At the same time I've grouped the $ARCH-linux-user and $ARCH-softmmu
builds together (hoping FS cache helps) and grouped all $ARCH-softmmu
only builds into one target. This reduces the build matrix slightly
which will hopefully help with build times.

[Qemu-devel] [PATCH v2 2/4] .travis.yml: make the make slightly more parallel

[Alex Bennée]

The Travis VMs have 1.5 cores so we might as well make some use of the
paralellism.

[Qemu-devel] [PATCH v2 3/4] .travis.yml: pre-seed sub-modules for speed

[Alex Bennée]

A significant portion of the build time is spent initialising all the
sub-modules we use in the source tree. Often this is almost as long as
the build itself. By pre-seeding the .git/modules tree this will
hopefully improve things.

[Qemu-devel] [PATCH v2 4/4] .travis.yml: remove "make check" from main matrix

[Alex Bennée]

There are problems with unreliability in "make check" which still need
to be tracked down. As the tests are broadly the same for all targets if
added one explicit target to the matrix to run it. However this does
build all softmmu targets to ensure they at least "run"

Applied to -trivial.  Without any testing at all, as promised... :)
