[Pkg-xen-devel] Bug#639112: DomU access to dual-ported RAM area on PCI card fails
Hi David, Are the resources which you are trying to map from inside the domU correctly represented in the PCI device's BARs? I suspect that it would be worthwhile to try the Wheezy 3.2 based kernel in your domU. If this doesn't help then your best bet is likely to be to the upstream mailing list. Ian.

Hello Ian Campbell wrote:> Are the resources which you are trying to map from inside the domU > correctly represented in the PCI device's BARs?Yes (AFAICS). BAR0 of the device requests 4kB of memory space, and this is correctly reported under "/sys/class/uio/uio0/maps/map0/".> I suspect that it would be worthwhile to try the Wheezy 3.2 based > kernel in your domU.Wouldn't it make sense to upgrade the whole installation (dom0 + domU) to Wheezy, not just the domU?
