[Mesa-dev] [PATCH] i965: Disable L3 cache allocation for external buffers

2017-10-24 Thread Chris Wilson
Through the use of mocs, we can define the cache usage for any surface used by the GPU. In particular, we can request that L3 cache be allocated for either a read/write miss so that subsequent reads can be fetched from cache rather than memory. A consequence of this is that if we allocate a L3/LLC
