💅 artop6260_set_piomode — bestie, let's set some PIO timings

okay so real talk, this page is from the Kernel API Manual, section 9 (that's the kernel-functions girlies, iykyk). The function is literally called artop6260_set_piomode, and yes she's iconic, yes she's doing exactly what her name says 🎀

✨ NAME ✨

artop6260_set_piomode — initialize host controller PATA PIO timings 🦋

🌸 SYNOPSIS 🌸

void artop6260_set_piomode (struct ata_port *ap , struct ata_device
*adev );

Like, that's the whole vibe. Two args, no return, we're just out here setting timings 💅

👑 ARGUMENTS 👑

  • ap — the port whose timings we're configuring 🫶 this is the host controller port that's getting a glow-up
  • adev — the device we're configuring ✨ the actual drive that's getting its settings tweaked

🔥 DESCRIPTION 🔥

So what she does: she sets the PIO mode for the device, in host controller PCI config space. Basically she reaches into the PCI config space of the host controller and writes the PIO timing bits for that device. Main character energy, honestly 👑

And here's the ARTOP-specific tea ☕ — for ARTOP we must also clear the UDMA bits if we are not doing UDMA. Not optional, not a suggestion, it's a must. So if UDMA isn't in the picture, those bits get cleared, periodt.

But if UDMA is being used? Then the later call to set_dmamode will set the bits as required 🌈 so don't stress, she's got a whole team handling it.

LOCKING: None (inherited from caller). So like... the caller is responsible for the lock, not her. She's just visiting, she didn't bring her own lock 🔒 ngl that's kind of a flex

🎀 the sign-off 🎀

This little masterpiece lives in ./drivers/ata, dated October 2026, and it's part of the Kernel API Manual. Slay, honestly. Go set those PIO timings bestie, you're gonna ate 💜✨
