is anybody familiar with pci device driver on x86?

[Pavel Pisa]

Hello 宇,

you can find how to locate PCI card of given 
VENDOR_ID and DEVICE_ID and manipulate PCI control
space from RTEMS Cirrus driver (it works on x86) 

https://git.rtems.org/rtems/tree/c/src/lib/libbsp/i386/pc386/console/fb_cirrus.c#n309

Best wishes,

             Pavel
