sl82c105_configure_dmamode(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… sl82c105_configure_dmamode πŸ’…

okay so this is a page straight out of the Kernel API Manual, section 9, and it's lowkey iconic. it's giving "tiny function, huge responsibility" and honestly? slay.


✨ NAME ✨

sl82c105_configure_dmamode β€” sets the DMA mode in the chip</p>, that's the whole vibe πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

void sl82c105_configure_dmamode (struct ata_port *ap , struct ata_device *adev );

not me writing a function signature with a space before the comma, but we're keeping it exactly as it is because that's what the source says and we respect the source 🫢


🌸 ARGUMENTS 🌸

  • ap β€” the ATA interface πŸ’œ like, the port you're working with, the whole scene
  • adev β€” the ATA device ✨ the actual device on that interface, the main character of this little operation

πŸ”₯ DESCRIPTION πŸ”₯

so what it does is load the DMA cycle times into the chip, and it does that so the chip is ready for a DMA transfer to occur πŸ’«

that's it, that's the function. it's a setup step, a pre-game, the "getting ready with me" of DMA transfers. ngl it's a supportive icon that makes the transfer actually happen later πŸ‘‘


πŸ‘‘ SEE ALSO πŸ‘‘

the kernel file we're living in is ./drivers/ata/pata_sl82c105.c β€” and here's the whole friend group, no cap:

they all live together in ./drivers/ata and honestly what a squad 🌈


real talk bestie: the synopsis uses struct ata_port *ap and struct ata_device *adev, so those pointers are doing the actual work. don't forget to have both arguments ready or the vibe check fails πŸ’€

and that's the page!! brought to you by ./drivers/ata, dated October 2026, and it's literally titled sl82c105_configure_dmamode(9) in the Kernel API Manual β€” periodt, go configure your DMA mode, you absolute legend πŸ§šπŸ’–
