💖 libnvme_mi_mi_pda_read — like, the manual page, bestie 💖

okay so welcome to the libnvme API manual ✨ this one's all about libnvme_mi_mi_pda_read(9) and honestly? it's giving "small function, big responsibilities" energy 🎀

🌸 NAME 🌸

libnvme_mi_mi_pda_read — Read the NVMe-MI Persistent Data Area (PDA) 🫶

✨ SYNOPSIS ✨

int libnvme_mi_mi_pda_read (struct libnvme_mi_ep *ep , enum
nvme_mi_pda_dformat dformat , __u32 dofst , __u32 dlen , void *data ,
size_t *data_len );

that's the whole vibe right there 💅

🦋 ARGUMENTS 🦋

  • ep — the endpoint for MI communication. like, the connection bestie, this is who we're talking to 😌
  • dformat — the data format to use for dofst and dlen, see enum nvme_mi_pda_dformat. it decides what the units mean, iykyk 🌈
  • dofst — starting offset, in units of dformat, into the PDA to read. where we start, fr fr ⭐
  • dlen — length, in units of dformat, to read from the PDA starting at dofst. how much we're grabbing 📏
  • data — buffer to receive the PDA contents. the lil bucket for the goods 🍓
  • data_len — in: size of data; out: length of data actually returned. it goes in one number and comes out another, main character energy honestly 👑

🧚 DESCRIPTION 🧚

Performs an NVMe-MI PDA Read command ✨ no cap, that's the whole bit.

heads up bestie: check out the PDA Size (PDAS) and Supported Data Format (SDFORMAT) fields of struct nvme_mi_port_smb to find the size and supported dformat values of the PDA on a given port 🔥 that's where the deets live, don't skip the vibe check.

💜 RETURN 💜

The nvme command status if a response was received (see enum nvme_status_field), or a negative error code otherwise. so like — status if it worked, negative number if it did not, and that's the tea 💀

okay that's the whole page, love u, go read some persistent data area 💖
