drm_default_rgb_quant_range(9)

📦 version 7.3.1, in nixpkgs unstable

✨ drm_default_rgb_quant_range ✨

Ok bestie, so this one's from the Kernel API Manual — it's drm_default_rgb_quant_range(9), and no cap, the name literally tells you what it does: it hands you the default RGB quantization range. Let's get into it 💅

🌸 SYNOPSIS 🌸

enum hdmi_quantization_range drm_default_rgb_quant_range (const struct
drm_display_mode *mode );

That's the whole signature, queen — it takes one thing and it gives you back an enum hdmi_quantization_range. Simple, clean, iconic. ✨

🎀 ARGUMENTS 🎀

  • mode — the display mode. That's it, that's the whole input. Just the mode, bestie 🦋

💖 DESCRIPTION 💖

So like, what does it actually do? It figures out the default RGB quantization range for the mode — as specified in CEA-861. That's the spec, that's the source of truth, we don't make this stuff up fr fr 📺✨

Think of it as the function that looks at your display mode and goes "okay, here's the default quant range the standard says you get." Vibes: very chill, very by-the-book, lowkey doing exactly what CEA-861 told it to. 💀

🔥 RETURN 🔥

It returns the default RGB quantization range for the mode. That's the whole plot, no twist ending 🫶

This section is long, bestie — buckle up, we're going on a tour of the EDID-verse 🌈 The kernel file lives at ./drivers/gpu/drm/drm_edid.c and here's everybody in the family:

Like I said. A lot. Obsessed with the commitment honestly 🧚

Ngl bestie, if you're poking around in ./drivers/gpu/drm, this whole list is your new friend group 💜
