💖 nvme_fc_register_localport(9) 💖

okay so bestie, welcome to the nvme_fc_register_localport(9) page — it lives in the Kernel API Manual, and it's literally the glow-up moment where an LLDD tells the kernel "hey, this NVMe host FC port exists now 🦋". Buckle up, we're registering a port.

✨ NAME ✨

nvme_fc_register_localport — the transport entry point that an LLDD calls to register the existence of a NVME host FC port. that's it, that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

int nvme_fc_register_localport (struct nvme_fc_port_info *pinfo , struct
nvme_fc_port_template *template , struct device *dev , struct
nvme_fc_local_port **portptr );

four args, one int coming back, iconic behavior honestly 👑

🎀 ARGUMENTS 🎀

  • pinfo — pointer to information about the port to be registered. like, the port's whole little profile 🫶
  • template — LLDD entrypoints and operational parameters for the port. this is where the driver shows up with its personality 💫
  • dev — physical hardware device node port corresponds to. Will be used for DMA mappings. so yeah, it's doing real work, not just standing there 🔥
  • portptr — pointer to a local port pointer. Upon success, the routine will allocate a nvme_fc_local_port structure and place its address in the local port pointer. Upon failure, local port pointer will be set to 0. so on the bad path it gets zeroed out — that's your little "nothing to see here" signal 🙈

⭐ RETURN ⭐

a completion status. Must be 0 upon success; a negative errno (ex: -ENXIO) upon failure.

no cap: 0 = slay, negative errno = not slay. a negative errno is a failure code, so treat it as such 💀
