Subject: drm/ttm/memcg/lru: enable memcg tracking for ttm and amdgpu driver
Date: Mon, 30 Jun 2025 14:49:19 +1000 [thread overview]
Message-ID: <20250630045005.1337339-1-airlied@gmail.com> (raw)
Hi all,
tl;dr: start using list_lru/numa/memcg in GPU driver core and amdgpu driver for now.
This is a complete series of patches, some of which have been sent before and reviewed,
but I want to get the complete picture for others, and try to figure out how 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 what
obj cgroups were designed for and I'm reusing the page/objcg intergration that
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=heads
One problem is there are a lot of delayed action, that probably means the testing
needs a bit more robustness, but the tests validate all the basic paths.
Regards,
Dave.
