accessing a PCIe register from userspace through kmem or other ways ?

[Luigi Rizzo]

Hi,
I'd like to test the rate at which I can access device registers
on a PCIe card, and was wondering whether I need to patch a device
driver, or perhaps I can use /dev/kmem once I figure out where
the registers are mapped ?

thanks
luigi
