STRUCT HL_DIO_STATS(9)

💅 struct hl_dio_stats(9) — like, the Kernel API Manual, bestie 🎀

okay so welcome to the Kernel API Manual page for struct hl_dio_stats, and honestly? it's giving "let me count my Direct I/O wins and losses" and I'm obsessed. ✨

---

🌸 NAME 🌸

struct hl_dio_stats — Direct I/O statistics. that's it, that's the vibe. it's a little struct that keeps receipts on your DIO ops. 💅

---

🦋 SYNOPSIS 🦋

bestie, here's the whole shape of her. every field, verbatim, no cap:

struct hl_dio_stats {
    u64 total_ops;
    u64 successful_ops;
    u64 failed_ops;
    u64 bytes_transferred;
    size_t last_len_read;
 };

---

✨ Members ✨

• total_ops — total number of operations attempted. like, every single one that showed up to the party, whether it slayed or flopped. 🫶
• successful_ops — number of successful operations. the ones that ate and left no crumbs. 👑
• failed_ops — number of failed operations. it happens, we don't talk about it, but the struct does keep count. 💀
• bytes_transferred — total bytes successfully transferred. only the successes get counted here, so it's the good-good number. 🔥
• last_len_read — length of the last read operation. yes, just the last one. main character read energy, iykyk. 🎀

go touch grass in these files fr fr:

• Kernel file ./drivers/accel/habanalabs/common/hldio.h struct hl_p2p_region(9), struct hl_dio(9)

🌈 lowkey reminder: keep every field spelled exactly like above, because the kernel does not do typos and neither should you 💖

and that's the page, bestie!! mwah 💋 this lil beauty lives in ./drivers/accel/habanalabs/common and the version/date stamp on the original was October 2026 — so yeah, future-dated icon behavior, we love to see it. ⭐🌸🦋
