okay so welcome to radisys_qc_issue(9), straight outta the Kernel API Manual, bestie 💖 this one is literally about issuing a command and it’s giving main-character kernel energy fr fr.

🎀 NAME 🎀

radisys_qc_issue — command issue, periodt 💅

---

✨ SYNOPSIS ✨

unsigned int radisys_qc_issue (struct ata_queued_cmd *qc );

---

💅 ARGUMENTS 💅

• qc — the command that’s pending, iykyk 🦋

---

🦋 DESCRIPTION 🦋

So this gets called when the libata layer is literally about to issue a command 👑. We wrap this interface so we can load the correct ATA timings if necessary — that’s the whole vibe, no cap.

Our logic also clears TIME0/TIME1 for the other device, so that even if we get this wrong, cycles to the other device will be made PIO0 😭. Like, we’re being safe about it, periodt.
