xe_sriov_pf_disarm_guard(9)

💅 xe_sriov_pf_disarm_guard — bestie, it's time to DISARM the guard

okay so real talk, this is a page straight out of the Kernel API Manual (that's the manual name, bestie, we're in the kernel docs now 🎀). The function we're stanning today is xe_sriov_pf_disarm_guard(9), and yes, it does exactly what it says on the tin: Disarm the guard. Periodt. 💅

---

✨ SYNOPSIS ✨

void xe_sriov_pf_disarm_guard (struct xe_device *xe , struct xe_guard
*guard , bool lockdown , void *who );

like, she takes four things and returns nothing. void. no cap. 🫶

---

🌸 ARGUMENTS 🌸

• xe — the PF xe_device. that's your physical function device, the main character of this whole situation 👑
• guard — the xe_guard to disarm. yes, this guard. we're disarming it. she's done her job 🫡
• lockdown — a bool telling you which mode you're disarming from: true means disarm from lockdown mode, false means disarm from exclusive mode. choose wisely bestie 😭
• who — the address of the indirect owner, or NULL if it's a caller. so like, if you're the one doing it, pass NULL and own it 💖

---

🔥 DESCRIPTION 🔥

okay so, first things first, and this is important:

This function can only be called on PF. only. PF only. do not come in here with a VF, it's not giving what you think it's giving 💀

Otherwise? She's literally just a simple wrapper for xe_guard_disarm ✨ — but with extras. The extras being additional debug messages and xe_assert, so that any illegal calls get caught easily instead of quietly ruining your whole day. it's giving protective best friend energy, fr fr 🧚

So like, the guard gets disarmed, you get debug messages, and if you did something illegal, xe_assert is gonna let you know. iconic behaviour honestly 🌈
