ACARDIDE(4)

📦 version 11.0, in nixpkgs unstable

✨ ACARDIDE ✨

okay so welcome to acardide, section 4 of the Kernel Interfaces Manual — aka the driver for Acard IDE disk controllers 🎀

💖 NAME 💖

acardide — the acard IDE disk controllers driver, bestie. literally what it says on the tin ✨

🦋 SYNOPSIS 🦋

acardide* at pci? dev ? function ? flags 0x0000

that's the whole vibe check right there 🫶

🌸 DESCRIPTION 🌸

so like, the acardide driver is the main character for these IDE controllers, no cap:

  • Acard ATP850U Ultra33
  • Acard ATP860 Ultra66
  • Acard ATP860-A Ultra66
  • Acard ATP865-A Ultra100

it literally does the hardware interface thing for the ata(4) driver 💅 that's the whole job, and it ate.

now the tea on the flags ☕ — the 0x0002 flag forces the acardide driver to disable DMA on chipsets where DMA would normally be enabled. which, lowkey, is a debugging aid sort of situation, or a way to work around problems when the IDE controller is wired up to the system incorrectly 🙈 like if someone did the cabling wrong, this is your little rescue move.

fr fr though — you're using 0x0002 because something is already sus. don't come for me when DMA gets turned off on purpose. that's the entire point, bestie 💀

go read these, they're iconic:

💀 BUGS 💀

okay bestie, hear me out — the timings used for the PIO and DMA modes for the controllers listed above are for a PCI bus running at 30 or 33 MHz. so this driver may not work properly on overclocked systems 😭 like it's giving "built for stock speeds" energy and it will simply not be okay on your turbo build. periodt.

🌈 that's the whole page, mwah 💋 — this lil gem comes from Debian, dated October 24, 2003, and it's the driver era of a much simpler time 🎀 stay hydrated and don't overclock, iykyk 💜
