MEMBERS

dev

parent DRM device

port

OF node used by drm_of_find_possible_crtcs

head

list management

mutex

per-CRTC locking

base

base KMS object for ID tracking etc.

primary

primary plane for this CRTC

cursor

cursor plane for this CRTC

cursor_x

current x position of the cursor, used for universal cursor planes

cursor_y

current y position of the cursor, used for universal cursor planes

enabled

is this CRTC enabled?

mode

current mode timings

hwmode

mode timings as programmed to hw regs

x

x position on screen

y

y position on screen

funcs

CRTC control functions

gamma_size

size of gamma ramp

gamma_store

gamma ramp values

helper_private

mid-layer private data

properties

property tracking for this CRTC

state

current atomic state for this CRTC

acquire_ctx

per-CRTC implicit acquire context used by atomic drivers for legacy IOCTLs

DESCRIPTION

Each CRTC may have one or more connectors associated with it. This structure allows the CRTC to be controlled.
