Fast depth clears have the same depth/stencil alignment requirements
as other drawing operations. Therefore, we need to call
brw_workaround_depthstencil_alignment() from both the clear and
drawing paths.
Without this fix, we get image corruption if the following conditions
hold: (a) the first ever drawing operation to a depth miplevel (or the
first drawing operation after having used the texture for sampling) is
a clear, (b) the depth miplevel has a size that is eligible for fast
depth clears, and (c) the depth miplevel has an offset within the
miptree that isn't 8x8 aligned.
Fixes piglit "depthstencil-render-miplevels" tests with size 273.
NOTE: This is a candidate for stable branches
Both patches look okay to me.
