Hi Lauri,
FYI, since the userspace driver sends end-of-frame markers to the
kernel, the radeon kernel driver knows the current frame number and it
can also save the frame number of the last use of each buffer. We
should definitely use that to measure the buffer hotness, or just
prevent eviction if

Hi list, Thomas,
I will be investigating the use of a hotness score for each bo, to
replace the ping-pong causing LRU eviction in radeon*.
The goal is to put all bos that fit in VRAM there, in order of hotness;
a new bo should only be placed there if its hotness score is greater
than the lowest V
Hi!
