[Xen-users] Core Dump of a 64 bit domU from 32 bit dom0

[Puneet Lakhina <puneet.lakhina@xxxxxxxxx>]

Hi,

I have a setup in which the hypervisor and my domU are 64 bit but the
dom0 is 32 bit. Now when I try to core dump my domU from the dom0, the
".xen_prstatus" section of the elf file contains data based on 32 bit
struct sizes instead of 64 bit struct sizes (vcpu_guest_context *
noOfVcpus). That is the size of that section is 2800 * no of vcpus
(http://lxr.xensource.com/lxr/source/tools/include/xen-foreign/reference.size)
instead of 5168 * no of cpus.

Is there any way to get the right data in the core dump file?
