Subject: freedreno: Drop UNIFORM_BUFFER_OFFSET_ALIGNMENT to 32
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c6861b9f755e4a6b0dfe0afeaeaf8c5880e42312;p=mesa.git

freedreno: Drop UNIFORM_BUFFER_OFFSET_ALIGNMENT to 32

This is the value exposed by the a3xx-a4xx drivers according to an
official Adreno OpenGL ES Developer guide I found, and also a report I saw
for a5xx while googling.  Fixes renderdoc replay of a manhattan31 trace
captured on a Pixel 3a.
