nvme_mi_aem_process(9)

πŸ’– nvme_mi_aem_process πŸ’–

okay bestie, welcome to the libnvme API manual β€” this one's about nvme_mi_aem_process, and it's genuinely not that deep, i promise. it's a little function that goes and processes AEM on the endpoint you hand it. slay. let's get into it πŸ¦‹


✨ NAME ✨

nvme_mi_aem_process β€” Process AEM on the provided endpoint

like… that's it. that's the whole vibe. AEM? processed. endpoint? provided. iconic behavior πŸ’…


✨ SYNOPSIS ✨

int nvme_mi_aem_process (nvme_mi_ep_t ep , void *userdata );

look at her. two args, one int coming back at ya. no cap, that's the whole signature 🌸


✨ ARGUMENTS ✨

  • ep β€” Endpoint to process. this is the main character of the operation, the thing you're pointing at and saying "yes, do the AEM thing here" πŸ‘‘
  • userdata β€” Application provided context pointer for callback function. it's your lil backpack of stuff that gets passed along so your callback knows what's up πŸŽ€

✨ DESCRIPTION ✨

okay so here's the tea. call this function if poll indicates data is available on the fd provided by nvme_mi_aem_get_fd. that's the trigger condition, bestie β€” poll says data's ready, then you call this. simple as 🧚

when you do, it will call the fn pointer, aem_handler, that was provided with nvme_mi_aem_config. so basically you set up your handler earlier, and this is the moment it gets invoked. and here's the cute part: from within this callback, the application can call nvme_mi_aem_get_next_event to get aem event data. so like, the callback gets to reach back in and pull the actual event info. very demure, very mindful ✨

and the callback function should return NVME_MI_AEM_HNA_ACK for normal operation. periodt. don't forget that part, it matters πŸ’œ


✨ RETURN ✨

  • 0 is a success πŸŽ‰
  • nonzero is an error 😭

and if you get a nonzero, you may read errno for further details β€” that's where the real lore lives πŸ”₯


so yeah, that's nvme_mi_aem_process. poll says go, you call it, your aem_handler runs, you grab events with nvme_mi_aem_get_next_event, you return NVME_MI_AEM_HNA_ACK, and everybody's happy. check errno if not. mwah πŸ’‹

this lil love letter to you came straight out of the libnvme API manual, dated August 2026, and yes she's still serving nvme_mi_aem_process in the nvme_mi_aem_process(9) section header like the legend she is 🫢 go forth and process those AEMs, bestie πŸ’–
