Subject: Accessing PCI-E resources on 460EX
Date: Mon, 03 Nov 2008 23:09:22 +0200	[thread overview]
Message-ID: <490F6882.6050101@embedded-sol.com> (raw)

Hi,

I'm currently struggling with some application
that tries to access PCI-E memory by mmaping
address found in /sys/bus/pci/devices/<device>/resource

mmap() fails with "invalid argument" error, apparently
because on 460EX PCI addresses are 36-bit.

What is the correct way of accessing PCI-E from
userspace on this platform.

Thanks a lot.
