cacheable PCIe BAR

Is it possible to make BAR cacheable for PCIe hard macro on Stratix IV attached to standard PC with Intel processor? Anything special needs to be done in the driver for such case? Thanks!

There's no such thing as a cacheable BAR (per any PCI/PCIe specification). So you'll need to explain what you mean.

Which OS are you using?
