Standard Dual Channel PCI IDE Controller driver for FPGA controller


I developed a Xilinx FPGA that's a Generic Dual channel PCI IDE controller that operates in PIO mode only. Windows defaults to the "Standard Dual Channel PCI IDE Controller" driver and everything works fine. It defaults using the class codes.

How can I get Linux to use a generic PIO mode driver for my FPGA? Does Linux use class codes if vendor ID is not found?

Current FPGA settings for:
Vendor ID 0x10EE Xilinx FPGA as vendor
Device ID 0x0680
Class Code 0x01
Sub Class Code 0x01
Prog IF 0x05

Hello Wes,
I am currently working on implementing the very same design you described for Windows. I'm curious which BAR you had the IDE registers on and how you handled going from PCIe 32-bit transactions to IDE 8/16 bit transactions. Also any pointers you could share in generating the interrupts would be welcome.
Thanks.
