qed_db_recovery_del(9)

💅 qed_db_recovery_del — a whole kernel API manual moment, bestie

okay so first things first, the page is literally called qed_db_recovery_del(9) and it lives in the Kernel API Manual section 9 — that's the kernel-internals girlies, not your regular commands. buckle up 🎀

🌸 NAME 🌸

qed_db_recovery_del — literally removes doorbell information from the doorbell recovery mechanism. and like, plot twist: db_data serves as the key, because db_addr is not unique (iykyk, don't be weird about it) 🔔

---

✨ SYNOPSIS ✨

int qed_db_recovery_del (struct qed_dev *cdev , void __iomem *db_addr ,
void *db_data );

that's the whole signature, keep it exactly like that, no cap 💅

🫶 ARGUMENTS 🫶

• cdev — the Qed dev pointer. yes girl, the whole device, hand it over.
• db_addr — doorbell address. that's the one. the doorbell. 📍
• db_data — address where db_data is stored. this serves as the key for the entry to delete. so if you're out here thinking db_addr is enough to identify the entry... it is so not, it's not unique, use db_data bestie 😭🔑

⭐ RETURN ⭐

Int. that's it. that's the return. an int. go off king 🌈
