[Intel-gfx] [PATCH v2 0/2] Support 64 bpp half float formats

[Kevin Strasser]

This series defines new formats and adds implementation to the i915 driver.
Since posting v1 I have removed the pixel normalize property, as it's not needed
for basic functionality. Also, I have been working on adding support to
userspace.

I have submitted an RFC to Mesa to make use of the new formats:

My igt branch is reworked to drop usage of pixel normalize and includes use
of f16c intrinsics to speed up conversion:

I also have a libdrm branch with fp16 coverage added to modetest:
  https://gitlab.freedesktop.org/strassek/drm/commits/fp16

To serve as a smoke test of the whole stack I have a modified version of
kmscube:
