+
+ uxa: Disable bo reuse after binding to a scanout
+
+ On gen6+, bo are expected to be LLC by default. However, as using the bo
+ for the scanout causes it to be moved into the uncached domain, this
+ assumption is then false and we should release the bo back to the system
+ rather than spread the uncached buffers around. The most common
+ allocator of scanouts is for pageflipping which are already non-reusable
+ due to the DRI2 export, so there should actually be little impact.
