cec_get_edid_spa_location(9)

💖 NAME 💖

okay so bestie, welcome to the cec_get_edid_spa_location(9) page from the Kernel API Manual — yes, that manual 💅. The whole vibe is: cec_get_edid_spa_location — find location of the Source Physical Address ✨

🌸 SYNOPSIS 🌸

unsigned int cec_get_edid_spa_location (const u8 *edid , unsigned int
size );

🎀 ARGUMENTS 🎀

• edid — the EDID, aka the main-character input 🫶
• size — the size of the EDID, gotta know how much EDID we're working with 💅

🦋 DESCRIPTION 🦋

This EDID is expected to be a CEA-861 compliant, which means that there are at least two blocks and one or more of the extensions blocks are CEA-861 blocks. No cap.

The returned location is guaranteed to be <= size-2. That's the safety vibe check ✅

This is an inline function since it is used by both CEC and V4L2. Ideally this would go in a module shared by both, but it is overkill to do that for just a single function. Like, literally, one function does not need a whole shared-module era 😭
