Hi, Here's a drm-next PR for the new "dmem" cgroup Maarten and I worked on. Given that it's only user for now is DRM, Tejun agreed to merge it through DRM. This is based on the series sent by Maarten here: https://lore.kernel.org/all/20241204134410.1161769-1-dev@xxxxxxxxxxxx/ The three last patches are not part of it, for different reasons: - patch 5: we haven't had the acks from the amdgpu maintainers - patch 6: I didn't feel comfortable merging a patch defined as a "hack" - patch 7: it's not clear yet how GEM is going to be supported, so we need to have further discussion on this one. Thanks!
