ACERIDE(4) 💖 — Kernel Interfaces Manual ✨

okay so bestie, this is aceride(4) and she’s literally the main character for the PCI IDE disk controllers driver vibe. No cap, this page is your group-chat recap, and we’re keeping every detail because that’s the whole point. 🫶

🌸 NAME 🌸

aceride — PCI IDE disk controllers driver

---

✨ SYNOPSIS ✨

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

---

💅 DESCRIPTION 💅

The aceride driver supports the Acer Labs M5229 IDE controllers, and it provides the interface with the hardware for the ata(4) driver. It’s giving “glue between your controller and ata(4)” energy, and honestly? Obsessed. 🎀

The 0x0002 flag forces the aceride driver to disable DMA on chipsets for which DMA would normally be enabled. Bestie, that’s your debugging-aid option, or your workaround when the IDE controller is wired up to the system incorrectly. Periodt. 🦋

fr fr, 0x0002 is not a cute little suggestion — it forces DMA off in those cases, so use it with the actual situation in mind. 💀

💀 BUGS 💀

The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 30 or 33 MHz. This driver may not work properly on overclocked systems. Ngl, that’s the “please don’t be surprised if overclocking makes it act up” warning, and it’s staying right here. 😭
