megaraid_mbox_build_cmd(9)

💅 megaraid_mbox_build_cmd(9) — a Kernel API Manual moment 🎀

okay bestie, welcome to the glow-up of megaraid_mbox_build_cmd(9), straight out of the Kernel API Manual ✨ this one's a function page, so grab your lil' iced coffee and let's get into it 🫶

---

✨ NAME ✨

megaraid_mbox_build_cmd — literally transforms the mid-layer scsi commands, no cap 💫

---

🌸 SYNOPSIS 🌸

scb_t * megaraid_mbox_build_cmd (adapter_t *adapter , struct scsi_cmnd
*scp , enum scsi_qc_status *busy );

---

🦋 ARGUMENTS 🦋

• adapter — the controller's soft state 💖 like, the whole vibe of the controller itself
• scp — a pointer to the mid-layer scsi command 👀 this is the lil' message you're passing along
• busy — gets set if the request could not be completed because of a lack of resources 😭 so yeah, if things go sideways resource-wise, this flag is telling you so

---

🔥 DESCRIPTION 🔥

so here's the tea: this function transforms the mid-layer scsi command into megaraid firmware lingua 💅 iykyk — it's a whole translation sitch.

Basically it takes the command that the mid-layer issued and converts it into the format that the megaraid firmware actually understands 🧚✨.

And plot twist: it also completes certain commands without ever sending them to firmware 👑 iconic behaviour honestly.
