ath5k_hw_get_isr(9)

💖 NAME 💖

okay so bestie, this is the ath5k_hw_get_isr(9) page from the Kernel API Manual — and it's all about get interrupt status ✨. Lowkey iconic.

✨ SYNOPSIS ✨

int ath5k_hw_get_isr (struct ath5k_hw *ah , enum ath5k_int
*interrupt_mask );

🎀 ARGUMENTS 🎀

• ah — the struct ath5k_hw in question 🫶
• interrupt_mask — the driver's interrupt mask, used to filter out interrupts in sw 💖

🦋 DESCRIPTION 🦋

So this function is literally used inside our interrupt handler to determine the reason for the interrupt — by reading the Primary Interrupt Status Register 👑.

It returns an abstract interrupt status mask that's mostly ISR, but with some uncommon bits mapped on some standard non-hw-specific positions — check out ath5k_int for that whole situation 🔥.

💀 NOTE 💀

⚠️ okay, important: we do write-to-clear, so the active PISR/SISR bits at the time this function gets called are cleared on return 😭. No cap, do not forget that part.
