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 ->fill_modesconnector vfunc for drivers that use the crtc helpers for output mode filtering and detection.

RETURNS

Number of modes found on connector.
