https://bugzilla.kernel.org/show_bug.cgi?id=214425 --- Comment #4 from Rafael Ristovski (rafael.ristovski@xxxxxxxxx) --- For what its worth, the following horrible incantation managed to release 2+GB of TTM buffers on one of my machines, after I purposefully ran a VRAM intensive game: > for i in {1..1000}; do cat /sys/kernel/debug/ttm/page_pool_shrink; done This seems to be the only sysfs mechanism to cause the memory to get released, and as of now I am not aware of a... better and mainly "cleaner" alternative. Newer kernel versions seem to feature https://www.kernel.org/doc/html/next/admin-guide/mm/shrinker_debugfs.html, which might be a better alternative, but I have not tested it yet, and its usage is not exactly clear to me. -- You may reply to this email to add a comment.
