megasas_build_ldio(9)

💅 megasas_build_ldio(9) — section 9, Kernel API Manual, bestie

Okay so real talk: this is megasas_build_ldio(9), a kernel API page from section 9, and it's lowkey the function that gets your regular SCSI IOs their frames. Let's get into it ✨

---

🌸 NAME 🌸

megasas_build_ldio — prepares IOs to logical devices. That's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

int megasas_build_ldio (struct megasas_instance *instance , struct
       scsi_cmnd *scp , struct megasas_cmd *cmd );

---

💖 ARGUMENTS 💖

• instance — the adapter soft state, aka the controller's whole personality 🫶
• scp — the SCSI command. yes bestie, that SCSI command 💅
• cmd — the command that's getting prepped and made all pretty for the trip

---

✨ DESCRIPTION ✨

Frames (and their accompanying SGLs) for regular SCSI IOs are built by this function. No cap — if it's a normal SCSI IO, this is the function handling it 🌈

okay that's the whole page, you ate that 💅

Cute little sign-off so you know where this came from: source is ./drivers/scsi/megaraid, dated October 2026, and yes it's still megasas_build_ldio(9) bestie 🦋✨🎀
