2023-11-27drm/ttm: Schedule delayed_delete worker closerRajneesh Bhardwaj1-2/+4
Try to allocate system memory on the NUMA node the device is closest to and try to run delayed_delete workers on a CPU of this node as well. To optimize the memory clearing operation when a TTM BO gets freed by the delayed_delete worker, scheduling it closer to a NUMA node where the memory was initially allocated helps avoid the cases where the worker gets randomly scheduled on the CPU cores that are across interconnect boundaries such as xGMI, PCIe etc. This change helps USWC GTT allocations on NUMA systems (dGPU) and AMD APU platforms such as GFXIP9.4.3.

2023-03-07drm/ttm: Fix a NULL pointer dereferenceThomas Hellström1-1/+1
The LRU mechanism may look up a resource in the process of being removed from an object. The locking rules here are a bit unclear but it looks currently like res->bo assignment is protected by the LRU lock, whereas bo->resource is protected by the object lock, while *clearing* of bo->resource is also protected by the LRU lock. This means that if we check that bo->resource points to the LRU resource under the LRU lock we should be safe. So perform that check before deciding to swap out a bo. That avoids dereferencing a NULL bo->resource in ttm_bo_swapout().

2021-08-16drm: ttm: Don't bail from ttm_global_init if debugfs_create_dir failsDan Moulding1-2/+0
In 69de4421bb4c ("drm/ttm: Initialize debugfs from ttm_global_init()"), ttm_global_init was changed so that if creation of the debugfs global root directory fails, ttm_global_init will bail out early and return an error, leading to initialization failure of DRM drivers. However, not every system will be using debugfs. On such a system, debugfs directory creation can be expected to fail, but DRM drivers must still be usable. This changes it so that if creation of TTM's debugfs root directory fails, then no biggie: keep calm and carry on.

We create a bunch of debugfs entries as a side-effect of ttm_global_init() and then never clean them up. This isn't usually a problem because we free the whole debugfs directory on module unload. However, if the global reference count ever goes to zero and then ttm_global_init() is called again, we'll re-create those debugfs entries and debugfs will complain in dmesg that we're creating entries that already exist. This patch fixes this problem by changing the lifetime of the whole TTM debugfs directory to match that of the TTM global state.
