Subject: How to combine two PCIe devices in one domain?
Date: Mon, 10 Feb 2014 16:18:12 +0800	[thread overview]
Message-ID: <52F88B44.7080501@gmail.com> (raw)

Hi all,

I have a driver module which would drive two PCIe devices to access a same memory area.
As the two devices are in different domains, I should map the memory to every PCIe device. And also the mapped address may be different for individual PCIe device.
How could I combine these two PCIe device in one domain so they share some address space?

Thanks.
