30 * Atomic hardware plane allocator
32 * The hardware plane allocator is solely based on the atomic plane states
33 * without keeping any external state to avoid races between .atomic_check()
34 * and .atomic_commit().
36 * The core idea is to avoid using a free planes bitmask that would need to be
37 * shared between check and commit handlers with a collective knowledge based on
38 * the allocated hardware plane(s) for each KMS plane. The allocator then loops
39 * over all plane states to compute the free planes bitmask, allocates hardware
40 * planes based on that bitmask, and stores the result back in the plane states.
42 * For this to work we need to access the current state of planes not touched by
43 * the atomic update. To ensure that it won't be modified, we need to lock all
44 * planes using drm_atomic_get_plane_state(). This effectively serializes atomic
45 * updates from .atomic_check() up to completion (when swapping the states if
46 * the check step has succeeded) or rollback (when freeing the states if the
47 * check step has failed).
49 * Allocation is performed in the .atomic_check() handler and applied
50 * automatically when the core swaps the old and new states.
