okay bestie, welcome to the Kernel API Manual page for lpfc_nvme_prep_io_dma(9) — yes, the name is a whole mouthful, and yes, we’re gonna get through it together. 🫶

🌸 NAME 🌸

lpfc_nvme_prep_io_dma — Issue an NVME-over-FCP IO ✨

✨ SYNOPSIS ✨

int lpfc_nvme_prep_io_dma (struct lpfc_vport *vport , struct lpfc_io_buf
       *lpfc_ncmd );

🎀 ARGUMENTS 🎀

• vport — pointer to a host virtual N_Port data structure. literally the vport bestie 💖
• lpfc_ncmd — Pointer to lpfc scsi command. yes, that’s the command vibe 🦋

👑 DESCRIPTION 👑

okay so the driver registers this routine as its io request handler. main character behavior, honestly. 💅

This routine issues an fcp WQE with data from the lpfc_nvme_fcpreq data structure to the rport indicated in lpfc_nvme_rport. no cap, that’s the flow. 🔥

Return value: 0 — Success. TODO: What are the failure codes. 😭 the TODO is literally right there in the original, bestie, we don’t make the rules.
