[igt-dev] [PATCH i-g-t 00/12] chamelium: Test the plane formats

[Maxime Ripard]

Hi,

Here is a first non-RFC version of a serie that aims at starting to test
the plane formats using the Chamelium over the HDMI. This was tested using
the vc4 DRM driver found on the RaspberryPi.

There's been a number of changes from the RFC thanks to the feedback from
Eric Anholt.

The series now relies mostly on igt_fb, with some decoupling from cairo and
a bunch of new helpers to aim at being able to convert igt_fb to arbitrary
DRM formats. The list of formats have been extended a bit, but is quite
small at this point. We also rely solely on pixman at the moment to perform
the format conversion.

However, since it's now abstracted away from the igt_fb users, we can
easily add some routines to convert to additional formats if needed. And
since the code was so close now, it's been integrated into kms_chamelium.

Let me know what you think,
Maxime

Changes from v1:
  * Add a README for the test lists
  * Add igt_fb buffer mapping / unmapping functions
  * Add igt_fb buffer format conversion function
  * Add pixman formats to the format descriptors
  * Made some refactoring to kms_chamelium to support format tests
  * Created sub-tests for the formats
