💅 MRAID_GET_DEVICE_MAP (9) — the Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is MRAID_GET_DEVICE_MAP 🫶 no cap, this one's a whole macro and it's lowkey iconic.

✨ NAME ✨

MRAID_GET_DEVICE_MAP — device ids 🎀

like, that's literally the whole vibe. device ids. periodt.

---

🌸 SYNOPSIS 🌸

MRAID_GET_DEVICE_MAP (adp , scp , p_chan , target , islogical );

five arguments, all up in there, and yes you have to pass every single one fr fr 💀

🦋 ARGUMENTS 🦋

• adp — the adapter's soft state 💖 that's your controller's whole little personality, its state of being.
• scp — mid-layer scsi command pointer ✨ the command that's cruising through the mid-layer, pointing right at you.
• p_chan — physical channel on the controller 🌈 like which lane on the controller we're talking about.
• target — target id of the device or logical drive number 👑 so either a device target id, or a logical drive number, depending on the situation.
• islogical — set if the command is for the logical drive 🎀 set it, and we know we're dealing with a logical drive. not set, and it's the other thing. iykyk.

💜 DESCRIPTION 💜

so this is a macro, right, and its whole job is to retrieve information about:

• the device class — logical or physical 🌸
• the corresponding physical channel
• and the target or logical drive number that goes with it 💅

that's it, that's the macro. it pulls that info out for you so you don't have to go digging around in structs like some kind of feral gremlin 😭 she's serving convenience, she's serving clarity, she ate and left no crumbs 🔥

lowkey go read that header if you want the full lore, this macro's just the door to the whole megaraid cinematic universe 🫶

and that's a wrap bestie!! this page came at you from ./drivers/scsi/megaraid, dated October 2026, in the Kernel API Manual — mwah 💋 stay hydrated, keep your pointers valid, and don't forget to check your islogical flag 🧚‍♀️💖
