Could we please also add a line which explicitly sets the precision in 3DSTATE_SF? That way it's clearer from the code what's going on. On Wed, Feb 20, 2019 at 11:19 AM Juan A. Suarez Romero wrote: > On one side, when emitting 3DSTATE_SF, VertexSubPixelPrecisionSelect is > used to select betwee

[Mesa-dev] [PATCH] anv: advertise 8 subpixel precision bits

2019-02-20 Thread Juan A. Suarez Romero
On one side, when emitting 3DSTATE_SF, VertexSubPixelPrecisionSelect is used to select between 8 bit subpixel precision (value 0) or 4 bit subpixel precision (value 1). As this value is not set, means it is taking the value 0, so 8 bit are used. On the other side, in the Vulkan CTS tests, if the r
