SYNOPSIS

int drm_atomic_nonblocking_commit(struct drm_atomic_state * state);

ARGUMENTS

state

atomic configuration to check

DESCRIPTION

Note that this function can return -EDEADLK if the driver needed to acquire more locks but encountered a deadlock. The caller must then do the usual w/w backoff dance and restart. All other errors are fatal.

Also note that on successful execution ownership of state is transferred from the caller of this function to the function itself. The caller must not free or in any other way access state. If the function fails then the caller must clean up state itself.

RETURNS

0 on success, negative error code on failure.
