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.

Hi all,

I have a driver module which would drive two PCIe devices to access a same memory area with intel IOMMU enabled.
As the two devices are in two different domains, I should map the memory to every PCIe device.

How could I combine these two PCIe device in one domain so they share some address space?

Thanks.
