* drm/ttm: Fix TTM page pool accountingAnthony DeRossi2021-03-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freed pages are not subtracted from the allocated_pages counter in ttm_pool_type_fini(), causing a leak in the count on device removal.

After some bisection and investigation, it appears this resulted from the recent changes to ttm_bo_move_to_lru_tail(). Previously when a buffer was pinned, the buffer would be removed from the LRU once ttm_bo_unreserve to maintain the LRU list when pinning or unpinning BOs. However, since: commit 3d1a88e1051f ("drm/ttm: cleanup LRU handling further") We've been exiting from ttm_bo_move_to_lru_tail() at the very beginning of the function if the bo we're looking at is pinned, resulting in the pinned BO never getting removed from the lru and as a result - causing issues when it eventually becomes time for eviction. So, let's fix this by calling ttm_bo_del_from_lru() from ttm_bo_move_to_lru_tail() in the event that we're dealing with a pinned buffer. v2 (chk): reduce to only the fixing one liner since we always want to call the callback whenever we would move on the LRU.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently drivers get called to move a buffer, but if they have to move it temporarily through another space (SYSTEM->VRAM via TT) then they can end up with a lot of ttm->driver->ttm call stacks, if the temprorary space moves requires eviction. Instead of letting the driver do all the placement/space for the temporary, allow it to report back (-EMULTIHOP) and a placement (hop) to the move code, which will then do the temporary move, and the correct placement move afterwards. This removes a lot of code from drivers, at the expense of adding some midlayering. I've some further ideas on how to turn it inside out, but I think this is a good solution to the call stack problems. v2: separate out the driver patches, add WARN for getting MULTHOP in paths we shouldn't (Daniel) v3: use memset (Christian) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: hristian König <christian.koenig@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201109005432.861936-2-airlied@gmail.com

First of all depending on the allocation size it is between 3 (1GiB) and 5 (1MiB) times faster than the old implementation. It makes better use of buddy pages to allow for larger physical contiguous allocations which should result in better TLB utilization at least for amdgpu. Instead of a completely braindead approach of filling the pool with one CPU while another one is trying to shrink it we only give back freed pages. This also results in much less locking contention and a trylock free MM shrinker callback, so we can guarantee that pages are given back to the system when needed. Downside of this is that it takes longer for many small allocations until the pool is filled up. We could address this, but I couldn't find an use case where this actually matters. We also don't bother freeing large chunks of pages any more since the CPU overhead in that path isn't really that important. The sysfs files are replaced with a single module parameter, allowing users to override how many pages should be globally pooled in TTM. This unfortunately breaks the UAPI slightly, but as far as we know nobody ever depended on this. Zeroing memory coming from the pool was handled inconsistently. The alloc_pages() based pool was zeroing it, the dma_alloc_attr() based one wasn't. For now the new implementation isn't zeroing pages from the pool either and only sets the __GFP_ZERO flag when necessary. The implementation has only 768 lines of code compared to the over 2600 of the old one, and also allows for saving quite a bunch of code in the drivers since we don't need specialized handling there any more based on kernel config. Additional to all of that there was a neat bug with IOMMU, coherent DMA mappings and huge pages which is now fixed in the new code as well. v2: make ttm_pool_apply_caching static as reported by the kernel bot, add some more checks v3: fix some more checkpatch.pl warnings Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Madhav Chauhan <madhav.chauhan@amd.com> Tested-by: Huang Rui <ray.huang@amd.com> Link: https://patchwork.freedesktop.org/patch/397080/?series=83051&rev=1
