intel_fb_get_format_info(9)

💖 intel_fb_get_format_info 💖

okay so bestie, welcome to the Kernel API Manual entry for intel_fb_get_format_info — yes that's the whole title, yes it's a mouthful, we love her anyway 🫶. She lives in the i915 display world and she's here to hand you the format info for a pixel format, but specifically the version of it that your modifier wants. lowkey iconic.

---

✨ NAME ✨

intel_fb_get_format_info — get a modifier-specific format information. that's the whole job. she gets. she gives. periodt 💅

---

🌸 SYNOPSIS 🌸

const struct drm_format_info * intel_fb_get_format_info (u32
pixel_format , u64 modifier );

so she takes a u32 and a u64 and hands you back a const struct drm_format_info *. no cap, that's the whole signature 🎀

---

🦋 ARGUMENTS 🦋

• pixel_format — the pixel format. that's it. that's the argument. (the manpage is a woman of few words and honestly? respect 💜)
• modifier — the modifier. again: minimal, mysterious, main character energy ✨

---

⭐ RETURN ⭐

She returns the format information for pixel_format that's specific to modifier 💖 — but heads up: if the modifier doesn't override the format, you get NULL. not an error, not a vibe check fail, just NULL. so like, check for it, bestie 🫶

ngl the arguments section is doing the absolute bare minimum and i respect the restraint, but do not let that fool you — the return value genuinely can be NULL, so handle it 🌈
