2025-03-07drm/amd: Keep display off while going into S4Mario Limonciello2-2/+14
When userspace invokes S4 the flow is: 1) amdgpu_pmops_prepare() 2) amdgpu_pmops_freeze() 3) Create hibernation image 4) amdgpu_pmops_thaw() 5) Write out image to disk 6) Turn off system Then on resume amdgpu_pmops_restore() is called. This flow has a problem that because amdgpu_pmops_thaw() is called it will call amdgpu_device_resume() which will resume all of the GPU. This includes turning the display hardware back on and discovering connectors again. This is an unexpected experience for the display to turn back on. Adjust the flow so that during the S4 sequence display hardware is not turned back on.

GEM code usually tests for imports if import_attach has been set in struct drm_gem_object.

2025-03-05drm/xe: Increase the XE_PL_TT watermarkThomas Hellström1-2/+1
The XE_PL_TT watermark was set to 50% of system memory. The idea behind that was unclear since the net effect is that TT memory will be evicted to TTM_PL_SYSTEM memory if that watermark is exceeded, requiring PPGTT rebinds and dma remapping. But there is no similar watermark for TTM_PL_1SYSTEM memory. The TTM functionality that tries to swap out system memory to shmem objects if a 50% limit of total system memory is reached is orthogonal to this, and with the shrinker added, it's no longer in effect. Replace the 50% TTM_PL_TT limit with a 100% limit, in effect allowing all graphics memory to be bound to the device unless it has been swapped out by the shrinker.

2025-03-05drm/xe: Add a shrinker for xe bosThomas Hellström8-18/+513
Rather than relying on the TTM watermark accounting add a shrinker for xe_bos in TT or system memory. Leverage the newly added TTM per-page shrinking and shmem backup support. Although xe doesn't fully support WONTNEED (purgeable) bos yet, introduce and add shrinker support for purgeable ttm_tts. v2: - Cleanups bugfixes and a KUNIT shrinker test. - Add writeback support, and activate if kswapd. v3: - Move the try_shrink() helper to core TTM. - Minor cleanups. v4: - Add runtime pm for the shrinker. Shrinking may require an active device for CCS metadata copying. v5: - Separately purge ghost- and zombie objects in the shrinker. - Fix a format specifier - type inconsistency. (Kernel test robot). v7: - s/long/s64/ (Christian König) - s/sofar/progress/ (Matt Brost) v8: - Rebase on Xe KUNIT update. - Add content verifying to the shrinker kunit test. - Split out TTM changes to a separate patch. - Get rid of multiple bool arguments for clarity (Matt Brost) - Avoid an error pointer dereference (Matt Brost) - Avoid an integer overflow (Matt Auld) - Address misc review comments by Matt Brost. v9: - Fix a compliation error. - Rebase. v10: - Update to new LRU walk interface. - Rework ghost-, zombie and purged object shrinking. - Rebase. v11: - Use additional TTM helpers. - Honor __GFP_FS and __GFP_IO - Rebase. v13: - Use ttm_tt_setup_backup(). v14: - Don't set up backup on imported bos. v15: - Rebase on backup interface changes.

2025-03-05drm/ttm: Add helpers for shrinkingThomas Hellström4-1/+158
Add a number of helpers for shrinking that access core TTM and core MM functionality in a way that make them unsuitable for driver open-coding. v11: - New patch (split off from previous) and additional helpers. v13: - Adapt to ttm_backup interface change. - Take resource off LRU when backed up.

2025-03-05drm/ttm: Add a macro to perform LRU iterationThomas Hellström2-4/+208
Following the design direction communicated here: https://lore.kernel.org/linux-mm/b7491378-defd-4f1c-31e2-29e4c77e2d67@amd.com/T/#ma918844aa8a6efe8768fdcda0c6590d5c93850c9 Export a LRU walker for driver shrinker use. The walker initially supports only trylocking, since that's the method used by shrinkes. The walker makes use of scoped_guard() to allow exiting from the LRU walk loop without performing any explicit unlocking or cleanup. v8: - Split out from another patch. - Use a struct for bool arguments to increase readability (Matt Brost). - Unmap user-space cpu-mappings before shrinking pages. - Explain non-fatal error codes (Matt Brost) v10: - Instead of using the existing helper, Wrap the interface inside out and provide a loop to de-midlayer things the LRU iteration (Christian König). - Removing the R-B by Matt Brost since the patch was significantly changed. v11: - Split the patch up to include just the LRU walk helper. v12: - Indent after scoped_guard() (Matt Brost) v15: - Adapt to new definition of scoped_guard() Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Acked-by: Dave Airlie <airlied@redhat.com> Acked-by: Christian König <christian.koenig@amd.com> Link: https://lore.kernel.org/intel-xe/20250305092220.123405-5-thomas.hellstrom@linux.intel.com

Use fault-injection to test partial TTM swapout and interrupted swapin.
