cmd64x_set_piomode(9)

okay bestie, welcome to cmd64x_set_piomode(9) from the Kernel API Manual — header folded in near the top, vibes immaculate 🎀

✨ NAME ✨

cmd64x_set_piomode — set initial PIO mode data 🦋

🌸 SYNOPSIS 🌸

void cmd64x_set_piomode (struct ata_port *ap , struct ata_device *adev
       );

🎀 ARGUMENTS 🎀

• ap — ATA interface. That’s the ATA interface bestie, periodt 💅
• adev — ATA device. The ATA device in question, no cap ✨

💖 DESCRIPTION 💖

So this function gets used when configuring the devices to set the PIO timings — and yes, the original literally says “ot” instead of “to,” and we’re preserving that lil typo like a historical artifact 🫶. All the actual work is done by the PIO/MWDMA setting helper. No cap: the helper is the main character here, and this function is the setup girlie 💅✨.
