[Xen-devel] HVM hypercalls, hvm_hypercall_table

["George Surka" <gsurka@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi everyone,

 

I am running XenEnterprise 3.1.0 (Xen v.3.0.3.0) on x86-32 hardware. I have noticed that the hvm_hypercall_table is initialized for only 6 hypercalls (memory_op, multicall, xen_version, event_channel_op, sched_op, and hvm_op). The hypercall_page for HVM domain is initialized with HVM exit (VMCALL instr.) - all stubs.

 

So, how do I do the other hypercalls (beyond those 6) from HVM domain? Do I just have to use INT 0x82 trap without using the hypercall-page (without using the HYPERVISOR_* hypercall macros in hypercall.h)?

 

Why there is just those six hypercalls implemented as HVM-hypercalls?

 

Thanks.

 

George
