STPCIDE(4)

💖 STPCIDE(4) 💖 — Kernel Interfaces Manual, group-chat edition 🎀

okay bestie, this is the STPCIDE(4) page and it's literally about the stpcide driver. No cap.

🌸 NAME 🌸

stpcide — STMicroelectronics STPC IDE disk controllers driver. That's the name, and yes she ate 💅

✨ SYNOPSIS ✨

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

💖 DESCRIPTION 💖

okay so the stpcide driver supports the STMicroelectronics STPC x86 SoC internal IDE controllers, and it provides the interface with the hardware for the ata(4) driver. Iconic bridge behavior, fr fr. The driver features DMA mode 2 and PIO mode 4 transfer speeds. Obsessed.

The 0x0002 flag forces the stpcide driver to disable DMA on chipsets for which DMA would normally be enabled. Lowkey useful as a debugging aid, or to work around problems where the IDE controller is wired up to the system incorrectly. 🫶

ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4) — go read those too bestie, iykyk.

💀 BUGS 💀

real talk: the timings used for the DMA and PIO modes are for STPC Atlas and its siblings with their PCI clock configured at 33 MHz. Other speeds including the STPC Vega Ultra-IDE controller will need adjustments. Not me warning you ahead of time 😭
