Thomas Hellström 754c232384 drm/pagemap, drm/xe: Ensure that the devmem allocation is idle before use ... In situations where no system memory is migrated to devmem, and in upcoming patches where another GPU is performing the migration to the newly allocated devmem buffer, there is nothing to ensure any ongoing clear to the devmem allocation or async eviction from the devmem allocation is complete. Address that by passing a struct dma_fence down to the copy functions, and ensure it is waited for before migration is marked complete. v3: - New patch. v4: - Update the logic used for determining when to wait for the pre_migrate_fence. - Update the logic used for determining when to warn for the pre_migrate_fence since the scheduler fences apparently can signal out-of-order. v5: - Fix a UAF (CI) - Remove references to source P2P migration (Himal) - Put the pre_migrate_fence after migration. v6: - Pipeline the pre_migrate_fence dependency (Matt Brost) Fixes: c5b3eb5a90 ("drm/xe: Add GPUSVM device memory copy vfunc functions") Cc: Matthew Brost <matthew.brost@intel.com> Cc: <stable@vger.kernel.org> # v6.15+ Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Acked-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> # For merging through drm-xe.
