2024-07-04drm/ttm: Always take the bo delayed cleanup path for imported bosThomas Hellström
Bos can be put with multiple unrelated dma-resv locks held. But imported bos attempt to grab the bo dma-resv during dma-buf detach that typically happens during cleanup. That leads to lockde splats similar to the below and a potential ABBA deadlock. Fix this by always taking the delayed workqueue cleanup path for imported bos. Requesting stable fixes from when the Xe driver was introduced, since its usage of drm_exec and wide vm dma_resvs appear to be the first reliable trigger of this.

2024-03-01drm/ttm: improve idle/busy handling v5Christian König
Previously we would never try to move a BO into the preferred placements when it ever landed in a busy placement since those were considered compatible. Rework the whole handling and finally unify the idle and busy handling. ttm_bo_validate() is now responsible to try idle placement first and then use the busy placement if that didn't worked. Drawback is that we now always try the idle placement first for each validation which might cause some additional CPU overhead on overcommit. v2: fix kerneldoc warning and coding style v3: take care of XE as well v4: keep the ttm_bo_mem_space functionality as it is for now, only add new handling for ttm_bo_validate as suggested by Thomas v5: fix bug pointed out by Matthew Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Zack Rusin <zack.rusin@broadcom.com> v3 Link: https://patchwork.freedesktop.org/patch/msgid/20240229134003.3688-1-christian.koenig@amd.com Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com>

2023-11-27drm/ttm: Schedule delayed_delete worker closerRajneesh Bhardwaj
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.

2023-02-06drm/ttm: clear the ttm_tt when bo->resource is NULLMatthew Auld
In the next few patches, when initially creating a ttm BO, the bo->resource is NULL, and the driver is then expected to handle the initial dummy move. However, if this is created as a system resource the first ttm_tt we create will always have the clear value set to false. Previously the initial ttm_tt would be created in ttm_bo_validate() with the clear parameter always set to true.

This change adds the dma_resv_usage enum and allows us to specify why a dma_resv object is queried for its containing fences. Additional to that a dma_resv_usage_rw() helper function is added to aid retrieving the fences for a read or write userspace submission. This is then deployed to the different query functions of the dma_resv object and all of their users. When the write paratermer was previously true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise. v2: add KERNEL/OTHER in separate patch v3: some kerneldoc suggestions by Daniel v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in the rebase pointed out by Bas.
