From: Eric Anholt Date: Fri, 28 Dec 2018 03:37:13 +0000 (-0800) Subject: v3d: Fix stencil sampling from a separate-stencil buffer. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c51d125d1851b76fbee5a0d99d81e92eac705939;p=mesa.git v3d: Fix stencil sampling from a separate-stencil buffer. When the sampler view is in sample-stencil mode, we need to return uint stencil values. To do that, fill in the format table to return R8I, and have the sampler view point at the separate stencil buffer.
