💖 drm_panel_get_modes(9) 💖

okay so this is a page from the Kernel API Manual (that's the manual name, bestie, consider it folded in 🫶), and it's about drm_panel_get_modes — literally the function that goes and asks a panel "hey girl what modes can u do?" 🔥

✨ NAME ✨

drm_panel_get_modes — probe the available display modes of a panel

🌸 SYNOPSIS 🌸

int drm_panel_get_modes (struct drm_panel *panel , struct drm_connector
*connector );

🎀 ARGUMENTS 🎀

  • panel — a DRM panel. that's the whole vibe. it's the panel 💅
  • connector — a DRM connector. also exactly what it says on the tin 🦋

👑 DESCRIPTION 👑

so here's the tea: the modes that get probed from the panel are automatically added to the connector that the panel is attached to. no extra steps, no manual labour, it just happens. the way that it handles that for you?? iconic. ⭐

💜 RETURN 💜

  • On success: the number of modes available from the panel 🔥
  • On failure (which here means literally no modes): 0

so yeah, zero is the sad path, don't be fooled into thinking it's a success with no modes — it's the "no modes" answer 😭

🌈 SEE ALSO 🌈

Kernel file ./drivers/gpu/drm/drm_panel.c

like, the entire panel friend group fr fr 🧚 the whole ./drivers/gpu/drm directory is basically the group chat 💀

and that's the whole page, bestie!! this one's living in ./drivers/gpu/drm and it's dated October 2026 in the Kernel API Manual — mwah, go read ur modes, ily, bye 🍓💖✨
