ERROR_GRAPHICS_CANT_EVICT_PINNED_ALLOCATION

ERROR_GRAPHICS_CANT_EVICT_PINNED_ALLOCATION (0xC0262109) means the memory manager needed to evict an allocation but could not because the allocation was pinned. A pinned allocation must be unpinned or released before it can be moved out of the required segment.

What to check

  • Release locks, mappings, or explicit pins before requesting operations that require the allocation to be evicted.
  • Review the resource budget and avoid keeping large allocations permanently resident without a need.
  • If it follows a device reset, recreate resources rather than trying to preserve pre-reset pin state.
