[Mesa-dev] [PATCH] freedreno/a3xx: use the same layer size for all slices

[Ilia Mirkin]

We only program in one layer size per texture, so that means that all
levels must share one size. This makes the piglit test

bin/texelFetch fs sampler2DArray

have the same breakage as its non-array version instead of being
completely off.

Need to put this through a piglit run, but seems fairly obvious given what
fd3_texture does. Also see results of the texelFetch piglit.
