[Mesa-dev] [PATCH 0/2] i965: Add support for fp16 <-> fp64 conversions

[Samuel Iglesias Gonsálvez]

Hello,

This series implements support for doing fp16 <-> fp64 conversions on
i965. The PRM says we need to do an intermediate conversion to a 32 bit
type.

This patch series applies on top of shaderInt16's patch series [0].
There is a branch for testing on Github:

$ git clone https://github.com/Igalia/mesa.git \
  -b siglesias/vulkan-fp16-fp64-conversions

There are tests for Vulkan CTS under review (CL#2246) for testing these
patches.

Best regards,

Sam
