DRM_HELPER_PROBE_SIN(9) DRM Internals DRM_HELPER_PROBE_SIN(9)NAMEdrm_helper_probe_single_connector_modes - get complete set of display
modes
SYNOPSIS
int
drm_helper_probe_single_connector_modes(struct drm_connector * connector,
uint32_t maxX,
uint32_t maxY);
ARGUMENTS
connector
connector to probe
maxX
max width for modes
maxY
max height for modes
LOCKING
Caller must hold mode config lock.
Based on the helper callbacks implemented by connector try to detect
all valid modes. Modes will first be added to the connector's
probed_modes list, then culled (based on validity and the maxX, maxY
parameters) and put into the normal modes list.
Intended to be use as a generic implementation of the ->probeconnector
callback for drivers that use the crtc helpers for output mode
filtering and detection.
RETURNS
Number of modes found on connector.
