drm_edid_encode_panel_id(9)

💅 drm_edid_encode_panel_id(9) 💅

okay bestie so this is a page from the Kernel API Manual and honestly? it's a little one but it slaps. it's all about drm_edid_encode_panel_id, which makes an ID you can match against drm_edid_get_panel_id(). matching era, fr fr 🎀

✨ NAME ✨

drm_edid_encode_panel_id — Encode an ID for matching against drm_edid_get_panel_id() 🦋

---

🫶 SYNOPSIS 🫶

drm_edid_encode_panel_id (vend_chr_0 , vend_chr_1 , vend_chr_2 ,
product_id );

like, that's the whole call. four things in, one little ID out. periodt 💅

---

🌸 ARGUMENTS 🌸

• vend_chr_0 — the first character of the vendor string. yeah, just one character. she's tiny but she matters 💖
• vend_chr_1 — the second character of the vendor string. the middle child 🥺
• vend_chr_2 — the third character of the vendor string. last but never least ✨
• product_id — the 16-bit product ID. as in literally 16 bits, no cap 🔥

---

👑 DESCRIPTION 👑

so the whole reason this is a macro — and bestie this is the important part — is so it can be calculated at compile time and used as an initializer. that's it. that's the vibe. compile-time girlie 💫

for instance, watch this:

drm_edid_encode_panel_id('B', 'O', 'E', 0x2d08) => 0x09e52d08

like. 'B', 'O', 'E' and 0x2d08 walk in, and 0x09e52d08 walks out. ate and left no crumbs 😭🔥

---

⭐ RETURN ⭐

a 32-bit ID per panel. one panel, one ID, main character energy 👑

---

🌈 SEE ALSO 🌈

• Kernel file ./include/drm/drm_edid.h — go read her, she's iconic 🎀
• drm_edid_decode_mfg_id(9) — the decode counterpart, iykyk
• drm_edid_decode_panel_id(9) — also the decode counterpart, we love a matched set 🫶

---

lowkey a reminder that everything above is exactly what the page says — the macro bit, the compile-time bit, the initializer bit — so don't go adding your own lore to it, bestie 🙈
