Subject: radeon: fix cube maps for non-mm path
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4d2b392a0ac597f8b7f88006746660e8f0fe09ea;p=mesa.git

radeon: fix cube maps for non-mm path

drm cmd checker would refuse cube emits
also fix an issue in the cs path which would calculate the register
offset off by one dword.
Only same testing done as original code (none except compile tested).
