[igt-dev] [PATCH 0/3] Add support for fp16 formats

[Kevin Strasser]

Kernel support for these formats has landed in drm-next.
This series adds a library for converting floats to and from fp16 which enables
a couple of tests to use the new formats.

fp16 coverage is included in these tests:
  kms_plane_scaling
  kms_rotation_crc

Kevin Strasser (3):
  lib: Add halffloat implementation
  lib/igt_fb: Add support for fp16 formats through conversion
  tests/kms_plane_scaling: Skip testing unsupported fp16 features
