drm_mode_parse_command_line_for_connector(9)

Usage

bool drm_mode_parse_command_line_for_connector(const char * mode_option, struct drm_connector * connector, struct drm_cmdline_mode * mode);

Arguments

mode_option

optional per connector mode option

connector

connector to parse modeline for

mode

preallocated drm_cmdline_mode structure to fill out

Overview

This parses mode_option command line modeline for modes and options to configure the connector. If mode_option is NULL the default command line modeline in fb_mode_option will be parsed instead.

This uses the same parameters as the fb modedb.c, except for an extra force-enable, force-enable-digital and force-disable bit at the end:

<xres>x<yres>[M][R][-<bpp>][@<refresh>][i][m][eDd]

The intermediate drm_cmdline_mode structure is required to store additional options from the command line modline like the force-enabel/disable flag.

Returns

True if a valid modeline has been parsed, false otherwise.
