💖 qed_db_recovery_add(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, this is that manual, and today's main character is qed_db_recovery_add, a little function living its best life in the kernel. 🎀 What does it do? It adds doorbell information to the doorbell recovery mechanism. That's it. That's the whole vibe. 🔔✨

🦋 SYNOPSIS 🦋

int qed_db_recovery_add (struct qed_dev *cdev , void __iomem *db_addr ,
void *db_data , enum qed_db_rec_width db_width , enum qed_db_rec_space
db_space );

literally just five args and an int return, no cap. 🫶

🌸 ARGUMENTS 🌸

  • cdev — the Qed dev pointer 💅 like, the device you're doing all this for.
  • db_addr — the doorbell address 🔔 that's the spot.
  • db_data — the address of where db_data is stored. yes, the address of where it's stored, we said what we said 💀.
  • db_width — tells you whether the doorbell is 32b or 64b. (the page says it as 32b pr 64b and honestly we're keeping the typo, it's iconic 😭)
  • db_space — because doorbell recovery addresses can be user or kernel space, and this arg is how you say which 🌈.

⭐ RETURN ⭐

Returns an int. that's the whole return section, she's short and sweet 🍓
