radisys_set_dmamode(9) 💅

okay so bestie, this one is from the Kernel API Manual, and it’s all about initializing host controller PATA DMA timings. no cap. 🦋

✨ NAME ✨

radisys_set_dmamode — initialize host controller PATA DMA timings 💖

🎀 SYNOPSIS 🎀

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

🌸 ARGUMENTS 🌸

• ap — the port whose timings we’re configuring, periodt. 💅
• adev — the device to program. yep, that one. 🫶

🦋 DESCRIPTION 🦋

So what it does: it sets the MWDMA mode for the device, in the host controller PCI config space. that’s the whole vibe. ✨

LOCKING: None — it’s inherited from the caller. literally none of its own. 💀
