This is a complete series of patches, some of which have been sent before a= nd reviewed, but I want to get the complete picture for others, and try to figure out ho= w best to land this. There are 3 pieces to this: 01->02: add support for global gpu stat counters (previously posted, patch = 2 is newer) 03->07: port ttm pools to list_lru for numa awareness 08->14: add memcg stats + gpu apis, then port ttm pools to memcg aware list= _lru and shrinker 15->17: enable amdgpu to use new functionality. The biggest difference in the memcg code from previously is I discovered wh= at obj cgroups were designed for and I'm reusing the page/objcg intergration t= hat=20 already exists, to avoid reinventing that wheel right now. There are some igt-gpu-tools tests I've written at: https://gitlab.freedesktop.org/airlied/igt-gpu-tools/-/tree/amdgpu-cgroups?= ref_type=3Dheads One problem is there are a lot of delayed action, that probably means the t= esting needs a bit more robustness, but the tests validate all the basic paths.
