ps3_vuart_irq_setup(9)

💅 ps3_vuart_irq_setup(9) — from the Kernel API Manual, bestie 🎀

okay so this one is literally the setup girly for the system virtual uart virq, and she's from the Kernel API Manual ✨ (yes the whole manual, she's got range).

---

🌸 NAME 🌸

ps3_vuart_irq_setup — the one where you Setup the system virtual uart virq. 🫶

---

✨ SYNOPSIS ✨

int ps3_vuart_irq_setup (enum ps3_cpu_binding cpu , void* virt_addr_bmp
, unsigned int *virq );

like that's the whole signature, no cap 💅

---

🎀 ARGUMENTS 🎀

• cpu — an enum ps3_cpu_binding that tells you which cpu the interrupt should be serviced on, iykyk 🧚
• virt_addr_bmp — the virtual uart interrupt bitmap, and it's caller supplied bestie, so bring your own 🍓
• virq — the assigned Linux virq 💖

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — the system supports only a single virtual uart. like, one. singular. main character energy, no sharing 👑

so if you call this multiple times without freeing the interrupt in between? it's gonna return a wrong state error 😭 literally the system going "girl. no." 💀
