+1. That pretty much means large-scale CI. The i915 test suite has
suffered quite a bit over the past years because the CI infrastructure
didn't keep up. Result is that running full CI kills pretty much every
platform there is eventually, and it's really hard to get back to a
state where the testsuite can be used to catch regressions again.
