✨ drm_crtc_fill_gamma_555(9) ✨

okay so this is a page from the Kernel API Manual (yes, the drm_crtc_fill_gamma_555(9) one, bestie, you're in the right place 💖) and it's honestly such a slay little helper.

🌸 NAME 🌸

drm_crtc_fill_gamma_555 — bestie, this one programs a default gamma ramp for RGB555-like formats ✨ like it literally just fills in the gamma for you, no cap

🎀 SYNOPSIS 🎀

void drm_crtc_fill_gamma_555 (struct drm_crtc *crtc ,
drm_crtc_set_lut_func set_gamma );

she's void, she takes two things, she doesn't return anything, she just does it 💅

🦋 ARGUMENTS 🦋

  • crtc — the displaying CRTC, aka the main character of this whole operation 👑 this is the display controller we're out here programming for
  • set_gamma — the callback for programming the hardware gamma LUT 🔥 that's the function that actually goes and talks to the hardware for you

💜 DESCRIPTION 💜

Programs a default gamma ramp to hardware. that's it, that's the whole vibe 🫶 it takes your crtc and your set_gamma callback and hands off a default gamma ramp straight to the hardware. iconic behaviour, honestly.
