[igt-dev] [PATCH i-g-t 0/6] lib: Add tests validating media compressed surfaces

[Imre Deak]

Add test coverage to validate that surfaces in the media compressed
format are handled correctly (as part of the general E2E compression
validation). This involves setting up an AUX buffer for the given
surface - the same way it's done for render compressed surfaces - but
the media compressed format can only be produced by a media engine. The
simplest way for that is use the tiling convert command of the vebox
engine, so also add support for that.
