qla29xx_mpi_optrom_data(9)

💅 qla29xx_mpi_optrom_data(9) — like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual ✨ this one is a function called qla29xx_mpi_optrom_data, and it's literally the dump/load plug for MPI optrom data on the 29xx fam 🎀 iykyk.

---

✨ NAME ✨

qla29xx_mpi_optrom_data — Dump/load MPI optrom data for 29xx. that's it, that's the vibe 💅

---

🦋 SYNOPSIS 🦋

int qla29xx_mpi_optrom_data (struct scsi_qla_host *vha , uint16_t opts ,
void *buf , uint32_t offset , uint32_t length , enum
qla29xx_mpi_optrom_op op );

like, look at her go 😭 six whole arguments, main character energy fr fr.

🌸 ARGUMENTS 🌸

• vha — pointer to the SCSI QLogic host structure 🫶 that's the host babe, the whole context, the moment.
• opts — the options for the operation ✨ little flavor knobs, you know?
• buf — the buffer you're reading from / writing to 🎀 whichever way the data's flowing, this is the spot.
• offset — the MPI RAM address, in 32-bit words 👑 and bestie please clock this: MBC_LOAD_DUMP_MPI_RAM is word-addressed, so this is not a byte offset. not even a little. don't come for me with your byte math 💀
• length — length of the data, in bytes — it gets converted internally to a word count 🧚 so you give bytes, it handles the word-ification, we love a self-sufficient icon.
• op — the operation, either QLA29XX_MPI_OP_DUMP or QLA29XX_MPI_OP_LOAD 🌈 dumping out or loading in, pick your fighter.

---

⭐ RETURN ⭐

QLA_SUCCESS on success, or an error code on failure 🙈 so like… check it. always check it.
