ipr_test_intr(9)

💖 ipr_test_intr(9) — Kernel API Manual 💖

okay so bestie, welcome to the tiniest lil’ interrupt-handler page in the kernel friend group 💅✨

🎀 NAME 🎀

ipr_test_intr — handle the interrupt generated in ipr_test_msi().

✨ SYNOPSIS ✨

irqreturn_t ipr_test_intr (int irq , void *devp );

🌸 ARGUMENTS 🌸

• irq — the IRQ number, literally.
• devp — the PCI device struct.

🦋 DESCRIPTION 🦋

okay so this one is lowkey simple: it just sets the msi_received flag to 1, which is the lil’ signal that Message Signaled Interrupts are supported. That’s the whole vibe. No cap 🫶

Return value: 0 on success / non-zero on failure.
