💅 cec_get_edid_phys_addr(9) 💅

okay so bestie, this is a page from the Kernel API Manual — and no, it's not about the girlies, it's about the CEC subsystem in the kernel. we're literally digging through EDID data to find a physical address. stay with me, it's giving detective energy 🔍✨

✨ NAME ✨

cec_get_edid_phys_addr — find and return the physical address 🎀

no cap, that's the whole job. it goes looking and hands you the address back.

🌸 SYNOPSIS 🌸

u16 cec_get_edid_phys_addr (const u8 *edid , unsigned int size ,
       unsigned int *offset );

look at that signature, she's iconic 💅 three args, returns a u16. periodt.

🦋 ARGUMENTS 🦋

  • edid — pointer to the EDID data 💖 this is the blob you're snooping through, bestie.
  • size — size in bytes of the EDID data 🌸 gotta tell her how far she's allowed to look, or she's just wandering.
  • offset — If not NULL then the location of the physical address bytes in the EDID will be returned here. This is set to 0 if there is no physical address found. 🎯 so like, she'll drop the coordinates in here for you — but if she comes back empty-handed, it's a big fat 0, no cap.

💜 RETURN 💜

the physical address 🔥 or CEC_PHYS_ADDR_INVALID if there is none 😭 yeah, sometimes she just doesn't find it, and that's valid.
