Hi All,

We tested pv-on-hvm.But pv-on-hvm doesn't work by Hypercall optimizations.

・xen-ia64-unstable.hg : 13367
 [IA64] Hypercall optimizations

If we load xen-platform-pci.ko, the following errors occur.

 # insmod xen-platform-pci.ko
 xen_platform_pci: Unknown symbol __hypercall
 insmod: error inserting 'xen-platform-pci.ko': -1 Unknown symbol in module

It is necessary to export functio of __ hypercall() in unmodified_drivers.However, function of __hypercall() is defined by assembler code.

How should we define function of __hypercall() in unmodified_drivers?
Then, how should export symbol of __hypercall()?

Best Regards,

Takanori Kasai
