💅 mpt3sas_setup_direct_io(9) — from the Kernel API Manual, bestie

okay so you found a 9-section page, meaning it's kernel API tea, and this one is mpt3sas_setup_direct_io — the function that sets up the MPI request for WARPDRIVE Direct I/O. yes. WARPDRIVE. it's giving fast lane energy and we're obsessed 🔥

✨ NAME ✨

mpt3sas_setup_direct_io — setup MPI request for WARPDRIVE Direct I/O 🦋

🌸 SYNOPSIS 🌸

void mpt3sas_setup_direct_io (struct MPT3SAS_ADAPTER *ioc , struct
scsi_cmnd *scmd , struct _raid_device *raid_device ,
Mpi25SCSIIORequest_t *mpi_request );

like, exactly that. four args, void return, no cap 💅 (it's a void function so don't go looking for a return value, there isn't one!)

🎀 ARGUMENTS 🎀

• ioc — the per adapter object. your adapter's whole personality, basically. main character energy 👑
• scmd — pointer to the scsi_cmnd command object. the actual SCSI command that wants to go do stuff ✨
• raid_device — pointer to the _raid_device data structure. that's where the raid device info lives 🍓
• mpi_request — pointer to the SCSI_IO reqest message frame. and yes, "reqest" is spelled like that in the original and I am not fixing it, we respect the source 😭🙈

ngl bestie, the arg one-liners are literally the whole map here — per adapter, the scsi command, the raid device struct, and the message frame. that's it. that's the vibe check 💀

🫶 SEE ALSO 🫶

• Kernel file ./drivers/scsi/mpt3sas/mpt3sas_warpdrive.c — yeah the source file is in SEE ALSO, that's just how this page does it 💜

• mpt3sas_init_warpdrive_properties(9)

go read those next, iykyk 🌈 the whole warpdrive squad is right there ⭐

and that's the page, bestie 🧚 this one came out of ./drivers/scsi/mpt3sas with the date October 2026, filed under mpt3sas_setup_direct_io(9) — slay, periodt 💖
