[Mesa-dev] [PATCH v2 14/35] i965/blorp: Move intratile offset calculations out of surface state setup

Jason Ekstrand jason at jlekstrand.net
Tue Jul 26 22:02:05 UTC 2016


Previously we multiplied full x/y offsets, resolved tile aligned buffer
offset and intra tile offset based on that.  Now we let ISL to take into
account the msaa setting and we only multiply the resolved intra tile
offsets.
