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.
