[PATCH v2] drm/msm: Handle in-place remaps

2025-08-05 Thread Rob Clark
Detect and handle the special case of a MAP op simply updating the vma flags of an existing vma, and skip the pgtable updates. This allows turnip to set the MSM_VMA_DUMP flag on an existing mapping without requiring additional synchronization against commands running on the GPU. Signed-off-by: Ro
