What does NTSTATUS 0xC01E0111 (STATUS_GRAPHICS_CANT_RENDER_LOCKED_ALLOCATION) mean?

STATUS_GRAPHICS_CANT_RENDER_LOCKED_ALLOCATION

CPU and GPU access are crossing incorrectly

This status marks an ordering violation: an allocation is locked for CPU access while the current GPU command buffer tries to render with it. It is not fixed by changing the shader or command alone; the allocation must first leave the CPU-lock state through the intended unlock and synchronization sequence.

Make the ownership transition explicit

Log the lock owner, lock mode, CPU write completion, unlock call, GPU fence, and command-buffer references. Enforce the sequence CPU lock → CPU access → unlock → GPU submission, with synchronization where the resource is shared. This also helps distinguish the failure from a busy allocation that cannot yet be locked.
