Subject: radv/amdgpu: Let addrlib calculate the HTILE parameters.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dbecbab5aa6fec9d90089ff5e16bc74339edb955;p=mesa.git

radv/amdgpu: Let addrlib calculate the HTILE parameters.

Still not sure we can support miptrees when sampling from
HTILE enabled textures.

Added the tcCompatible winsys stuff while I'm at it.
