__amdgpu_ras_eeprom_read(9)

💅 __amdgpu_ras_eeprom_read(9) — Kernel API Manual, but make it make sense

okay so bestie, this whole page lives in the Kernel API Manual and it's about one little function that reads stuff out of an EEPROM. tiny function, big main character energy. let's get into it 🫶

---

✨ NAME ✨

__amdgpu_ras_eeprom_read — read indexed from EEPROM into buffer

like, the name literally spells it out: you give it an index, it reads from the EEPROM, and the bytes land in your buffer. no cap. 💖

---

🌸 SYNOPSIS 🌸

int __amdgpu_ras_eeprom_read (struct amdgpu_ras_eeprom_control *control
, u8 *buf , const u32 fri , const u32 num );

that's the whole vibe right there. four params, one int coming back at you ✨

---

🎀 ARGUMENTS 🎀

• control — pointer to control structure 🎛️ like, the control center for this whole operation
• buf — pointer to buffer to read into 📥 this is where the goods go
• fri — first record index, start reading at this index, absolute index 🔢 literally "first record index" — you start here, and it's an absolute index, not relative, don't get it twisted
• num — number of records to read 🍓 how many records you're grabbing from that starting point

---

🦋 DESCRIPTION 🦋

okay here's the important part, and it's giving mandatory pre-reading, so listen up 👑

The caller must hold the table mutex in control.

like, you, the caller, are responsible for holding that table mutex in control before you even think about calling this. not a suggestion. it's the rule. 🔒

and the return? it returns 0 on success, or -errno otherwise. that's it, that's the whole contract 💀 classic kernel behavior fr fr.
