[igt-dev] [RFC 0/5] Add support for fp16 formats

[Kevin Strasser]

This series adds support for testing new fp16 formats. As these formats
haven't yet landed in the kernel I am sharing this as an RFC.

In particular coverage is added to the following tests which
already enumerate through all formats advertised by each plane:
  kms_available_modes_crc
  kms_rotation_crc
  kms_plane_scaling

Kevin Strasser (5):
  lib: Add halffloat implementation
  include: Add fp16 format defines
  tests/kms_available_modes_crc: Add cases for 64bit formats
  lib/igt_fb: Add support for fp16 formats through conversion
  tests/kms_plane_scaling: Skip testing unsupported fp16 features
