[Qemu-devel] [PATCH] tests: virtio: separate ccw tests from libqos
Posted by Paolo Bonzini 7 years, 3 months ago 
Because qtest does not support s390 channel I/O, s390 only performs smoke tests on
those few devices that do not have any functional tests.  Therefore, every time we
add functional tests for a virtio device, the choice is between removing
those tests from the s390 suite (so that s390 actually _loses_ coverage)
or sprinkling the test with architecture checks.

This patch simply creates a ccw-specific test that only performs smoke tests on
all virtio-ccw devices.  If channel I/O support is ever added to qtest and libqos,
then this file can go away.  In the meanwhile, it simplifies maintenance and
makes sure that all virtio devices are tested.

I'm not that familiar with qtest/libqos, but that sounds like a
reasonable approach.

I think you could omit the virtio_net_nop test here, since we already
check that device in tests/pxe-test.c (and maybe also virtio_blk and
virtio_scsi since they are tested in tests/cdrom-test.c).

Anyway:

Thanks Conny and Thomas for the quick review.

Emanuele, please add this patch to your qgraph branch!  You can use "git
am -s" and cut-and-paste the original message source from thunderbird or
gmail into the Terminal.
