We want all validation (potential backing store allocation) to be part of a drm_exec transaction. Therefore add a drm_exec pointer argument to xe_bo_validate() and ___xe_bo_create_locked(). Upcoming patches will deal with making all (or nearly all) calls to these functions part of a drm_exec transaction. In the meantime, define special values of the drm_exec pointer: XE_VALIDATION_UNIMPLEMENTED: Implementation of the drm_exec transaction has not been done yet. XE_VALIDATION_UNSUPPORTED: Some Middle-layers (dma-buf) doesn't allow the drm_exec context to be passed down to map_attachment where validation takes place. XE_VALIDATION_OPT_OUT: May be used only for kunit tests where exhaustive eviction isn't crucial and the ROI of converting those is very small. For XE_VALIDATION_UNIMPLEMENTED and XE_VALIDATION_OPT_OUT there is also a lockdep check that a drm_exec transaction can indeed start at the location where the macro is expanded. This is to encourage developers to take this into consideration early in the code development process. v2: - Fix xe_vm_set_validation_exec() imbalance. Add an assert that hopefully catches future instances of this (Matt Brost) v3: - Extend to psmi_alloc_object Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> #v3 Link: https://lore.kernel.org/r/20250908101246.65025-2-thomas.hellstrom@linux.intel.com
