amdgpu_ras_eeprom_append(9)

💾 amdgpu_ras_eeprom_append(9) — like, the EEPROM RAS table's official record-dropper 💅

okay bestie, so this is a page from the Kernel API Manual — yes, that is the manual name, I'm not just being dramatic — and it's all about amdgpu_ras_eeprom_append. Sit down, hydrate, and let's get into it 🫶

✨ NAME ✨

amdgpu_ras_eeprom_append — append records to the EEPROM RAS table 🌸

Like, the whole gig. That's it. That's the function 💖

---

📜 SYNOPSIS 📜

int amdgpu_ras_eeprom_append (struct amdgpu_ras_eeprom_control *control
, struct eeprom_table_record *record , const u32 num );

That's the exact signature, no cap — copy it verbatim if you're typing it out, because literally every character matters here 🔥

---

🎀 ARGUMENTS 🎀

• control — pointer to the control structure. She's the main character, the one holding all the state 👑
• record — array of records to append. Plural energy, bestie — it's an array, not a single lil guy ✨
• num — number of records in the record array. Yes, you have to tell her how many. She's not psychic 💀

---

🌈 DESCRIPTION 🌈

So here's the vibe: amdgpu_ras_eeprom_append appends num records to the table, calculates the checksum, and then writes the table back to EEPROM. That's the whole glow-up — append, checksum, write back. Iconic, honestly 💅

Now, the important bit, so pay attention 🦋 — the maximum number of records that can be appended is between 1 and control->ras_max_record_count, regardless of how many records are already stored in the table. Read that again. It's giving "the cap is the cap, bestie" — the existing contents do not move the needle. Periodt. 🙈

And the return values, because we always check those:

• Returns 0 on success — or if EEPROM is not supported at all (yes, same value, that's the deal, don't @ me) ✅
• Returns -errno on error — classic error-code behaviour, sad but true 😭

ngl, "returns 0 even when EEPROM isn't supported" is the kind of detail that will absolutely bite you if you skip it. So don't skip it, bestie. 🍓
