...to access the dual-ported RAM area on a PCI card using the Linux uio driver framework. The PCI passthru of the PCI card from Dom0 to DomU seems to be ok as the uio drivers are successfully loaded and the physical address and length of the DPM area are available under "/sys/class/uio/uio0/maps/map0/". Both Dom0 + DomU are based on Debian 6.0.2 (Squezze) Linux-2.6.32-5-xen-686 / Xen-4.0.1-2 I try to access the DPM area like this (pseudo code): fd = open("/dev/uio0"); dpm_addr = uio_get_addr("/sys/class/uio/uio0/maps/map0/addr"); dpm_size = uio_get_size("/sys...

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.
