qm_frozen(9)

💖 qm_frozen(9) 💖

okay so this is a page from the Kernel API Manual bestie, and it's all about one tiny little function called qm_frozen that has ONE job and honestly? she does it. let's get into it 🫶

---

✨ NAME ✨

qm_frozen — lowkey tries to froze the QM to cut off the continuous queue request. and listen: if there's a user on the QM, she returns failure without doing anything. no drama, no mess, she just leaves 🚪💅

---

🦋 SYNOPSIS 🦋

int qm_frozen (struct hisi_qm *qm );

literally that's it. one function. one argument. iconic behavior tbh ✨

---

🎀 ARGUMENTS 🎀

• qm — the qm that needs to be fronzen. (yes that's the original's spelling and we're keeping her, she's perfect 🙈💖)

---

🌸 DESCRIPTION 🌸

so what does she DO? this function frozes the QM — and once the QM is frozed, that's our green light to go ahead and do SRIOV disabling. that's the whole plot. main character energy from start to finish 👑
