💅 it821x_smart_qc_issue(9) 💅

okay so this is a page from the Kernel API Manual bestie, and we're talking about it821x_smart_qc_issue — literally the moment the IT821x driver gets its life together before issuing a command. stay with me 🫶

---

✨ NAME ✨

it821x_smart_qc_issue — wrap qc issue prot. that's the whole vibe. it wraps the qc issue prot. no cap 🎀

---

🌸 SYNOPSIS 🌸

unsigned int it821x_smart_qc_issue (struct ata_queued_cmd *qc );

---

🦋 ARGUMENTS 🦋

• qc — command 💖 (that's it, that's the argument, she's just a command)

---

🧚 DESCRIPTION 🧚

so basically, this function wraps the whole command issue sequence for the IT821x family. lowkey the drama is that we need to do our own device selection timing loads before the usual happenings kick off — like we're doing a little pre-show ritual before the main character (the standard issue path) walks on stage. ✨

it's giving "let me just fix my hair first" but for hardware timing. iconic behaviour tbh 👑
