hcall_reset_ptdev_intr(9)

💅 hcall_reset_ptdev_intr 💅

okay bestie, welcome to the hcall_reset_ptdev_intr(9) page — yes, that's the manual name, and yes, it's a kernel API moment. this one is all about resetting an interrupt for an assigned PCI device. iconic lowkey. 🎀

✨ SYNOPSIS ✨

long hcall_reset_ptdev_intr (u64 vmid , u64 irq );

that's the whole signature, no cap. two u64 args and a long coming back at you. 🦋

🌸 ARGUMENTS 🌸

• vmid — the User VM ID. literally just which user VM we're talking about. 👑
• irq — the Service VM GPA of the struct acrn_ptdev_irq. yep, that's a guest physical address pointing at that struct. keep up bestie. 💖

⭐ RETURN ⭐

• 0 on success — slay, it worked. ✅
• <0 on failure — not slay, something went wrong. 😭
