Subject: i965: Correctly set MAP_WRITE when creating the LLC program cache map.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2e3d825982ab7ee42671325a1c093f8635af1743;p=mesa.git

i965: Correctly set MAP_WRITE when creating the LLC program cache map.

Using a read-only mapping is completely bogus - we use this mapping to
write all new shaders to the cache.
