✨ NAME ✨

nvme_set_features_sw_progress — set the pre-boot software load count feature 💅

like. that's the whole vibe. it sets a feature. the feature is about pre-boot software load count. periodt 🫶

---

🌸 SYNOPSIS 🌸

int nvme_set_features_sw_progress (int fd , __u8 pbslc , bool save ,
       __u32 *result );

there she is 👑 four lil things go in, an int comes out. no cap.

---

🦋 ARGUMENTS 🦋

• fd — the file descriptor of the nvme device 🧚 this is your ticket in, your main character entry pass, the thing that says "yes hello i would like to talk to this drive please"
• pbslc — the Pre-boot Software Load Count ⭐ it's a __u8, so it's smol but it matters
• save — a bool that says whether to save the value across power states 💀 like, do you want this to survive a reboot or not, bestie, decide
• result — a pointer to a __u32 where the command completion result from CQE dword0 lands 🌈 that's the drive's lil receipt for what just happened

---

💜 RETURN 💜

so here's the tea ☕ this returns the nvme command status if a response was received — peep enum nvme_status_field for all the possible moods it can come back in 👀

and if no response showed up? you get -1, with errno set instead 🙈 classic.

bestie warning: don't just check for -1 and call it a day, okay? a response did come back sometimes and it's still a status code you gotta read. the -1 path is the "nobody picked up the phone" path 📞
