nvme_init_l...l_data_queue(9)

πŸ“¦ version 3.2, in arch rolling

πŸ’… nvme_init_lm_get_features_ctrl_data_queue(9)

okay so bestie, welcome to the libnvme API manual 🌸 β€” yes, the header is literally truncated to nvme_init_l...l_data_queue(9) and no, we are not going to fight the terminal about it. anyway, the function we're obsessing over is the full-length queen herself:

nvme_init_lm_get_features_ctrl_data_queue

and she does exactly what her name says, no cap. she sets up your passthru command so you can ask a controller about its Data Queue. let's get into it 🫢


✨ NAME ✨

nvme_init_lm_get_features_ctrl_data_queue β€” Initialize passthru command for Get Controller Data Queue feature πŸ’«

like, that's it. that's the whole job. and she ate.


🌈 SYNOPSIS 🌈

void nvme_init_lm_get_features_ctrl_data_queue (struct
libnvme_passthru_cmd *cmd , enum nvme_get_features_sel sel , __u16 cdqid
, struct nvme_lm_ctrl_data_queue_fid_data *qfd );

it's giving void, it's giving four arguments, it's giving absolutely no return value because she's a helper and she knows it. πŸŽ€


πŸŽ€ ARGUMENTS πŸŽ€

  • cmd β€” the passthru command you're gonna be working with. this is the vessel. the main character. she gets initialized. πŸ’…
  • sel β€” which type of attribute you want back, fr fr. check enum nvme_get_features_sel if you need the full menu of options. πŸ“
  • cdqid β€” the Controller Data Queue ID (CDQID), a __u16, very demure, very mindful. this is you telling it which queue you're asking about.
  • qfd β€” the Get Controller Data Queue feature data buffer, i.e. where the good stuff lands. struct nvme_lm_ctrl_data_queue_fid_data * if you want to be precise about it, and you should. ✨

πŸ”₯ DESCRIPTION πŸ”₯

so here's the tea, bestie: this function initializes the passthru command buffer for the Get Features command, and it sets the FID value to NVME_FEAT_FID_CTRL_DATA_QUEUE. πŸ¦‹

that's it. that's the whole vibe. you hand it a command, a selector, a CDQID and a buffer, and it wires up the Get Features request for the Controller Data Queue feature. lowkey iconic, highkey useful. 🌟

no return value, no exit statuses, no hidden surprises β€” void really said "I come with no baggage" 😭

that's the whole page, bestie πŸ’– this masterpiece comes to you via the libnvme API manual, dated October 2026 β€” so go forth, init that queue, and slay πŸ’…πŸ‘‘
