💖 cs5530_qc_issue(9) — Kernel API Manual 💖

okay bestie, this is the Kernel API Manual page for cs5530_qc_issue(9), and it's giving kernel-internals realness 👑

✨ NAME ✨

cs5530_qc_issue — command issue. that's the whole name, no cap. 💅

🌸 SYNOPSIS 🌸

unsigned int cs5530_qc_issue (struct ata_queued_cmd *qc );

that's the signature, literally copy-paste energy.

🎀 ARGUMENTS 🎀

• qc — the command that's pending, bestie. that's it, that's the arg. 🦋

💜 DESCRIPTION 💜

okay so this function gets called when the libata layer is about to issue a command. the whole reason we wrap this interface is so we can load the correct ATA timings if necessary. and specifically, there's a problem: there is only one MWDMA/UDMA bit. that's the plot twist. 😭🔥

periodt. wrap it up, load the timings if needed, respect the single MWDMA/UDMA bit situation.
