This driver-specific ioctl enables UMDs to control the memory attributes for GPU VMAs within a specified input range. If the start or end addresses fall within an existing VMA, the VMA is split accordingly. The attributes of the VMA are modified as provided by the users. The old mappings of the VMAs are invalidated, and TLB invalidation is performed if necessary. v2(Matthew brost) - xe_vm_in_fault_mode can't be enabled by Mesa, hence allow ioctl in non fault mode too - fix tlb invalidation skip for same ranges in multiple op - use helper for tlb invalidation - use xe_svm_notifier_lock/unlock helper - s/lockdep_assert_held/lockdep_assert_held_write - Add kernel-doc v3(Matthew Brost) - make vfunc fail safe - Add sanitizing input args before vfunc v4(Matthew Brost/Shuicheng) - Make locks interruptable - Error handling fixes - vm_put fixes v5(Matthew Brost) - Flush garbage collector before any locking. - Add check for null vma Cc: Matthew Brost <matthew.brost@intel.com> Cc: Shuicheng Lin <shuicheng.lin@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://lore.kernel.org/r/20250821173104.3030148-9-himal.prasad.ghimiray@intel.com Signed-off-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com>
