Steven, could you please tell me how exactly you tested the shrinker?
I realized that today's IGT doesn't have any tests for the Panfrost's madvise ioctl.
You may invoke "echo 2 > /proc/sys/vm/drop_caches" manually in order to trigger shrinker while 3d app is running actively (like a game or benchmark). Nothing crashing will be a good enough indicator that it works okay.
I may get an RK board next week and then will be able to test it by myself, so please don't hurry.
