Subject: amdgpu/addrlib: allow tileSplitBytes greater than row size
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=47de94a79414e241d4f37b8e38e3cc5396ce5b3f;p=mesa.git

amdgpu/addrlib: allow tileSplitBytes greater than row size

Carrizo row size is 1K, while tileSplitBytes is 2K for a 4xAA 32bpp
depth surface. Remove the sanity check that tileSplitBytes must be
greater than row size. There could be performance loss but may be
covered by non-split depth which enables tc-compatible read.
