NVME_SET_FEATURES_TEMP_THRESH2(2)

πŸ’– nvme_set_features_temp_thresh2 β€” the libnvme API manual, but make it cute πŸ’–

okay bestie, sit down, hydrate, because we're about to talk about nvme_set_features_temp_thresh2(9) from the libnvme API manual and honestly? she's iconic. this is the one that sets the temperature threshold feature on your NVMe device. yes. temperature. thresholds. we love a thermal moment. 🌑️✨


✨ NAME ✨

nvme_set_features_temp_thresh2 β€” Set temperature threshold feature πŸŽ€


🌸 SYNOPSIS 🌸

int nvme_set_features_temp_thresh2 (int fd , __u16 tmpth , __u8 tmpsel ,
       enum nvme_feat_tmpthresh_thsel thsel , __u8 tmpthh , bool save , __u32
       *result );

no cap, that's the whole signature, character for character, we do not edit the queen's code πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

every single one of these matters, so let's go one by one, main character energy only:

  • fd β€” File descriptor of nvme device 🫢 this is your ticket in, your little portal to the drive.
  • tmpth β€” Temperature Threshold 🌑️ the number itself. the vibe. the threshold.
  • tmpsel β€” Threshold Temperature Select πŸ‘‘ which threshold slot we're talking about.
  • thsel β€” Threshold Type Select ✨ what kind of threshold this is. type select. very choose-your-own-adventure.
  • tmpthh β€” Temperature Threshold Hysteresis πŸ¦‹ the hysteresis!! the little cushion so it doesn't freak out and flip-flop.
  • save β€” Save value across power states πŸ”₯ set this and it survives the power cycle. it's giving commitment.
  • result β€” The command completion result from CQE dword0 πŸ“¬ the receipt. literally the completion queue entry's dword0. iykyk.

πŸ’œ RETURN πŸ’œ

so what do you get back? here's the tea:

  • The nvme command status if a response was received β€” peep enum nvme_status_field for the full roster of statuses πŸ‘€
  • or -1 with errno set otherwise 😭 (that's the "something went sideways, check errno bestie" path)

🚨 no invented facts up in here, that's the entire return contract: status if you got a response, -1 + errno if you didn't. periodt.

that's the whole page, fr fr β€” written through-and-through with love for the libnvme API manual, and this little love letter is dated August 2026. stay cool, stay under threshold, and don't forget your hysteresis πŸ’–πŸŒΈπŸ¦‹πŸ’…
