__ras_eeprom_read(9)

💖 __ras_eeprom_read(9) — the Kernel API Manual glow-up ✨

okay so bestie, we're in the Kernel API Manual today and the vibe is reading indexed records out of an EEPROM — yes, that EEPROM, the little persistent-storage icon of the GPU world 🎀. This one's called __ras_eeprom_read, and she's giving "quiet little helper that does exactly one job and does it slay". Let's get into it 💅

---

🌸 SYNOPSIS 🌸

int __ras_eeprom_read (struct ras_eeprom_control *control , u8 *buf ,
       const u32 fri , const u32 num );

like, four arguments, one int return, zero drama. periodt 🔥

🦋 ARGUMENTS 🦋

• control — pointer to the control structure 💜. she's the main character, she holds the state.
• buf — pointer to the buffer we're reading into 🫶. yes, into. the data goes here. that's her whole purpose.
• fri — first record index ✨. this is where the reading starts, and ngl it's an absolute index, not some relative offset situation. lock that in your brain, bestie.
• num — number of records to read 🌸. how many we're grabbing, starting from fri. simple as.

---

🧚 DESCRIPTION 🧚

The caller must hold the table mutex in control — like, this is not optional, it's not a suggestion, it's the whole rule 😭. no mutex, no service. take care of that first, then call her.

Returns 0 on success ✨, and -errno otherwise 💀. that's it. that's the contract. iykyk.

⚠️ fr fr: go hold that table mutex in control before you call this. don't be the person who skips it. we all know that person. don't be them 🙈
