The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before

This patch adds a new option for xen config files for directly mapping hardware io memory into a vm.

The following series implements libxl_domain_config_init as per the libxl API requirement that each type has an init function. The first function does this in an open coded manner and is proposed for Xen 4.2. The second function is RFC only since it moves the definition of this type into the IDL and makes the required infrastructure updates to enable this. I think this is more 4.3 material at

Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,
