Module: Mesa
Branch: master
Commit: bbf2b5c4ffcb6755d34a5b698445aecf604e45fb
URL: http://cgit.freedesktop.org/mesa/mesa/commit/?id=bbf2b5c4ffcb6755d34a5b698445aecf604e45fb

radeon: Optimize memory handling for dma operations.
We keep dma buffer objects in list untill they have been unused for many
draw operations. Current limit of having 100 flushes is just guess for
good performance/memory trade off.
Moving WARN_ONCE macro to common context because it is used in multiple drivers.
