[PATCH v2 0/5] ARM hypercall ABI: 64 bit ready
Hi all,
this patch series makes the necessary changes to make sure that the
current ARM hypercall ABI can be used as-is on 64 bit ARM platforms:
- it defines xen_ulong_t as uint64_t on ARM;
- it introduces a new macro to handle guest pointers, called
XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to
have size 8 bytes on aarch64);
- it replaces all the occurrences of XEN_GUEST_HANDLE in hypercall
parameters with XEN_GUEST_HANDLE_PARAM.
On x86 and ia64 things should stay exactly the same.
On ARM all the unsigned long and the guest pointers...

Use of XEN_GUEST_HANDLE
Hi all,
I have recently started to go through xen source. I want to know the
usage of XEN_GUEST_HANDLE.
I see thats its just a macro which will prefix each data type with
__guest_handle_ . And DEFINE_XEN_GUEST_HANDLE(name) will just typedefs
''__guest_handle_name'' to be a pointer to a data type ''name '' .
What is the reason for such abstraction?
And how this XE...

A question related with symbol reference?
hi, my friends:
recently, i am reading the source codes about hypercall.
First, i study a simple hypercall, for example, the "do_xen_version".
In "xen-3.1.0-src\xen\common\kernel.c", the definition of "do_xen_version" is:
DO(xen_version) (int cmd, XEN_GUEST_HANDLE(void) arg)
{
....
}
according to the " #define DO(fn) long do_##fn ", the expanded form is "do_xen_version (...)".
then, in the "xen-3.1.0-src\xen\arch\x86\x86_32\entry.S", there is an item in the "hypercall_table", like this:
ENTRY(hypercall_table)
....

Currently, i am studying the way of hypercall's implementation.
i have already known the flow of hypercall's execuation, and i decided to add a new hypercall into the Xen.
first, i want to know the detail of one hypercall function, for example, "do_xen_version", but i can not find
the location of definition of "do_xen_version". who can help me?
