megasas_bios_param(9)

💅 megasas_bios_param(9) — Kernel API Manual, bestie edition ✨

okay so this one's from the kernel API manual — it's a lowkey little function that hands back the disk geometry for a disk. that's it. that's the whole vibe. 🎀

---

🌸 NAME 🌸

megasas_bios_param — returns disk geometry for a disk. literally just geometry. giving "here's your disk's measurements, bestie" energy 📏💖

---

✨ SYNOPSIS ✨

int megasas_bios_param (struct scsi_device *sdev , struct gendisk *unused , sector_t capacity , int geom[] );

---

🦋 ARGUMENTS 🦋

• sdev — the device handle. like, the disk's little ID card 🪪
• unused — a gendisk. yes bestie, the name is doing exactly what it says on the tin 🙈
• capacity — the drive's capacity. how much room she's got 🌈
• geom — the geometry parameters. the actual measurements go here, this is the output slot 💫

---

👑 SEE ALSO 👑

the kernel file herself: ./drivers/scsi/megaraid/megaraid_sas_base.c — go read the source, it's giving main character energy 📖🔥

mwah, that's the whole page — love u, stay safe out there in the kernel 💖 source and version live in ./drivers/scsi/megaraid, dated October 2026, and the whole thing answers to the name megasas_bios_param(9). slay 🌟🫶
