Synopsis
struct drm_connector_state * drm_atomic_get_connector_state ( | struct drm_atomic_state * state, |
| | struct drm_connector * connector); |
Arguments
state
global atomic state object
connector
connector to get state object for
Description
This function returns the connector state for the given connector,
allocating it if needed. It will also grab the relevant connector lock to
make sure that the state is consistent.
Returns
Either the allocated state or the error code encoded into the pointer. When
the error is EDEADLK then the w/w mutex code has detected a deadlock and the
entire atomic sequence must be restarted. All other errors are fatal.
