Subject: anv/blorp: Provide surface states for CCS resolves
X-Git-Tag: android-x86-8.1-r1~12213
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=1415e7a997fe525b4275c46a0e176faa38a8d297;p=android-x86%2Fexternal-mesa.git

anv/blorp: Provide surface states for CCS resolves

In the future, we plan on using this method to resolve images whose
surface state fast-clear value is dynamically updated during command
buffer execution. Start using it now for testing and to reduce churn
later on.
