drm_edid_decode_panel_id(9)

💅 drm_edid_decode_panel_id(9) — like, the Kernel API Manual, bestie ✨

okay so picture this: you've got a panel ID (yes, the same kind drm_edid_encode_panel_id() spits out) and you wanna know what even is it. That's this function. It's giving reverse-engineering, it's giving detective mode, it's giving "let me decode that for you real quick" 🕵️‍♀️💖

✨ SYNOPSIS ✨

void drm_edid_decode_panel_id (u32 panel_id , char vend[4] , u16 *product_id );

---

🎀 ARGUMENTS 🎀

• panel_id — the panel ID you want decoded. the main character of the whole operation 👑
• vend — a 4-byte buffer where the 3-letter vendor string goes, plus a ' ' termination. yes, FOUR bytes, the space counts, don't come for me 🙈
• product_id — the product ID gets returned here. this is where the answer lands 🫶

---

🌸 DESCRIPTION 🌸

so like, for instance — after you run this:

drm_edid_decode_panel_id(0x09e52d08, vend, product_id)

these will all be true, no cap:

vend[0] = 'B'
vend[1] = 'O'
vend[2] = 'E'
vend[3] = ' '
product_id = 0x2d08

BOE and 0x2d08. literally that simple. ate and left no crumbs 💅🔥
