Make virtme runs configurable
From @hverkuil
it should be possible to select how to run the regression tests (virtme), separately from limited vs full CI: 1) don't run them (default), 2) run 32 and 64 bit regression tests with 'test-media mc' (i.e. run all tests except the CEC tests), and 3) run them with 'test-media all'. 08:43 This assumes that the 32 bit and 64 bit tests each run in parallel. 08:47 Ricardo Ribalda mc is much faster than all? 08:48 otherwise I would recommend to just run all 08:49 The cec tests take a long time. 20-30 minutes. They emulate the CEC bus, and the CEC bus is really slow. 08:49 Few CPU cycles, lots of sleeping. 08:49 I generally do not run it except during the daily build or if I actually make changes to cec that need these tests.
