[Qemu-devel] [PATCH v1 0/3] Current Travis Patches

[Alex Bennée]

Hi,

Mine are mostly aimed at reducing the build time of a number of bits
of the matrix which keep tripping up on the time limit. I'll put the
pull-req in tomorrow if there are no major complaints.

Alex Bennée (2):
  travis: reduce coverage of gprof build
  travis: reduce time taken for trace-backend testing

Daniel P. Berrangé (1):
  travis: display config.log when configure fails

[Qemu-devel] [PATCH v1 1/3] travis: display config.log when configure fails

[Alex Bennée]

From: Daniel P. Berrangé <berrange@redhat.com>

When configure fails in CI systems we must be able to see the contents
of the config.log file to diagnose the root cause.

[Qemu-devel] [PATCH v1 2/3] travis: reduce coverage of gprof build

[Alex Bennée]

This build is regularly timing out and even switching off linux-user
wasn't enough. Instead explicitly choose a target list of broadly the
"major" architectures. This is enough to check the gprof build
machinery works without worrying about the actual coverage results.

I did try various YAML constructs for specifying CONFIG with
continuation but couldn't get any of them to work hence the very long
line.

[Qemu-devel] [PATCH v1 3/3] travis: reduce time taken for trace-backend testing

[Alex Bennée]

These builds are reaching regular timeouts and probably don't need to
be so widely exercised. ftrace and ust in particular are used in
conjunction with whole system profiling which makes most sense with
KVM setups, hence the native softmmu target.

We also expand simple to cover the multiple log backends while
restricting its scope to user-mode testing only.
