SISIDE(4)

okay so bestie, this is siside(4) from the Kernel Interfaces Manual, and it's literally the driver for Silicon Integrated System IDE disk controllers — main character energy for your storage setup 💖. Let's get into it.

✨ NAME ✨

siside — Silicon Integrated System IDE disk controllers driver. That's the whole vibe: it's the driver for those Silicon Integrated System IDE disk controllers, periodt 💅.

🎀 SYNOPSIS 🎀

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

💅 DESCRIPTION 💅

okay so the siside driver supports the Silicon Integrated System IDE controllers, and it provides the interface with the hardware for the ata(4) driver. no cap, that's its whole job: it's giving “I handle the hardware interface for ata(4)” realness 💖.

Now, about the 0x0002 flag: it forces the siside driver to disable DMA on chipsets for which DMA would normally be enabled. So if DMA would normally be on for that chipset, this flag says “nope, not today” and turns it off 🫶. This can be used as a debugging aid, or to work around problems where the IDE controller is wired up to the system incorrectly. lowkey useful if something's wired up weird.

💀 BUGS 💀

okay so here's the caveat, bestie: 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. This driver may not work properly on overclocked systems. fr fr, overclocked systems might get weird 😭 — don't say I didn't warn you.
