Thread-topic: [Xen-devel] RE: Access Memory Pages
Hi George,
                Thank you for your response. I have already implemented a 
custom hypercall and I want to access the memory pages allocated for a 
particular process, with in this hypercall handler. So I was not quite sure if 
I can initiate a hypercall from my custom hypercall handler i.e. from with in 
xen.
                I would appreciate if you could help further in this.
                Thanks.

Regards,
Satyajeet

Have you tried looking for an existing hypercall which does something
similar to what you want, to get a hint how it might be done?
