💅 drm_mode_parse_command_line_for_connector(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ — yes that's the manual name, i'm not copying the whole header line, we're being cute about it. anyway. this is the page for drm_mode_parse_command_line_for_connector, which is literally the function that reads your command line modeline for a connector. she's a parser. she's iconic. let's go 🎀

🌸 NAME 🌸

drm_mode_parse_command_line_for_connector — parse command line modeline for connector 💖

✨ SYNOPSIS ✨

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

🦋 ARGUMENTS 🦋

  • mode_option — optional per connector mode option. yes bestie, optional. she can be literally nothing, that's allowed 🙈
  • connector — the connector we're parsing the modeline for. she's the main character here 👑
  • mode — a preallocated drm_cmdline_mode structure that you hand over and she fills out. think of it as a little bowl you give her to put the vibes in 🍓

🌈 DESCRIPTION 🌈

so what does she actually do. she parses the mode_option command line modeline — all the modes and options — so your connector can get configured. that's the whole gig, no cap. 💅

the parameters are the same ones fb modedb.c uses, with one little extra at the end: a force-enable, a force-enable-digital, and a force-disable bit. dramatic? yes. useful? also yes ✨

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

and you can stack more options after the mode, separating each one with a comma 🫶. the valid options live in Documentation/fb/modedb.rst — go read it, iykyk.

the intermediate drm_cmdline_mode structure is required, bestie. it's where the extra options from the command line modline get stored — like the force-enable/disable flag. don't skip her, she's doing real work 💀

⭐ RETURN ⭐

True if a valid modeline has been parsed, False otherwise. simple as. slay 🌸
