Clear root PT entry and invalidate entire VM's address space when closing the VM. Will prevent the GPU from accessing any of the VM's memory after closing. v2: - s/vma/vm in kernel doc (CI) - Don't nuke migration VM as this occur at driver unload (CI) v3: - Rebase and pull into SVM series (Thomas) - Wait for pending binds (Thomas) v5: - Remove xe_gt_tlb_invalidation_fence_fini in error case (Matt Auld) - Drop local migration bool (Thomas) v7: - Add drm_dev_enter/exit protecting invalidation (CI, Matt Auld) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250306012657.3505757-12-matthew.brost@intel.com
