Pkg xen devel - Jul 2012 - 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.

Yes (AFAICS). BAR0 of the device requests 4kB of memory space, and this
is correctly reported under "/sys/class/uio/uio0/maps/map0/".

Wouldn't it make sense to upgrade the whole installation (dom0 + domU)
to Wheezy, not just the domU?
