lpfc_idiag_que_param_check(9)

💅 lpfc_idiag_que_param_check(9) — like, the vibe check for queue access params

okay so bestie, we're in the Kernel API Manual today and this function is genuinely the bouncer at the club door of the lpfc driver. it doesn't do the thing, it just makes sure the thing is even allowed in. 🎀

---

✨ NAME ✨

lpfc_idiag_que_param_check — queue access command parameter sanity check

like, it's the sanity check. for parameters. for queue access commands. no cap. 🧚

---

🌸 SYNOPSIS 🌸

int lpfc_idiag_que_param_check (struct lpfc_queue *q , int index , int
       count );

---

🦋 ARGUMENTS 🦋

• q — the pointer to the queue structure. yes, the actual queue. the whole vibe. 🫶
• index — the index into a queue entry.
• count — the number of queue entries to access.

---

💖 DESCRIPTION 💖

so the routine performs sanity check on device queue access method commands. that's it, that's the whole job, and it's lowkey iconic. it's the "wait, are you sure about this?" before anything sketchy touches a queue. main character energy in the most responsible way possible. ✨

---

🔥 RETURN 🔥

bestie, it's giving pass/fail:

• returns -EINVAL when it fails the sanity check 😭
• otherwise, it returns 0 👑

🍓 fr fr that's the whole page. go check your params before you touch the queue, i'm begging you.
