aer_isr_one_error(9)

✨ NAME ✨

okay so we're in the Kernel API Manual, and today's main character is aer_isr_one_error — the function that consumes error(s) signaled by an AER interrupt from a Root Port or RCEC. It's giving cleanup duty after the interrupt party, and honestly? Iconic. 💅✨

🌸 SYNOPSIS 🌸

Here's the signature, character for character, no cap:

void aer_isr_one_error (struct pci_dev *root , struct aer_err_source *e_src );

Yep, it returns void — no return value to stress about, bestie. 🫶

💅 ARGUMENTS 💅

• root — pointer to Root Port or RCEC that signaled AER interrupt. Basically the one who rang the error doorbell. 🛎️
• e_src — pointer to an error source. The actual tea being passed around. 🍵
