β¨ drm_dp_pcon_reset_frl_config(9) β¨
okay bestie, welcome to the Kernel API Manual β yes, that Kernel API Manual, the one with the vibes of a very long hallway in a server room π. This little page is about one function, and it's a whole mood. Let's get into it π
πΈ NAME πΈ
drm_dp_pcon_reset_frl_config β Re-Set HDMI Link configuration. That's it, that's the whole thing. Reset. HDMI link config. Iconic behavior, honestly π¦
β SYNOPSIS β
int drm_dp_pcon_reset_frl_config (struct drm_dp_aux *aux );
bestie it takes one thing. one. and it gives you back an int. we love a low-maintenance signature π
π ARGUMENTS π
auxβ the DisplayPort AUX channel. that's the whole parameter. that's the assignment. she's the main character of this function and she knows it π
π DESCRIPTION π
so here's the tea β: the function returns 0 if it's a success, and otherwise it hands you back a negative error code. literally that's it. no cap, no secret extra behavior, no hidden lore. success = 0, failure = some negative error code, and honestly that's a vibe check we can all respect πβ¨
lowkey a reminder: a negative return here means something went sideways, so don't just yeet the return value into the void, okay? π«Ά
π SEE ALSO π
okay this list is long, so buckle up buttercup, because there are a LOT of friends in this group chat π. and yes, dp helpers(9) really does show up twice β she's just that popular π
