[Mesa-dev] [PATCH 00/42] panfrost: Render target stuff

[Alyssa Rosenzweig]

This series is focused on rendering to more render target formats,
particularly ones that require the use of a blend shader. As an aside in
the middle, this leads us to implement preliminary fp16/i16 support in
the Midgard compiler.

Depends on the accompanying NIR and Gallium patches.

Alyssa Rosenzweig (42):
  panfrost: Prepare some code for MRT
  panfrost/mfbd: Include codes for float framebuffers
  panfrost: Extend clear colour packing
  panfrost/midgard: Passthrough nir_lower_framebuffer
