[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

help please - running a guest from an iSCSI disk ? getting more diagnostics than "cannot make domain: -3" ? how to make domain0 "privileged" ?
...vate.h:252
252 if ( (ret = do_xen_hypercall(xch, &hypercall)) < 0 )
Value returned is $4 = -1
(gdb) p errno
$5 = 1
Any ideas how to get this working, or on where I could get better
diagnostics ?
I''m guessing this is caused by this code in arch/x86/platform_hypercall.c :
ret_t do_platform_op(XEN_GUEST_HANDLE(xen_platform_op_t) u_xenpf_op)
{
ret_t ret = 0;
struct xen_platform_op curop, *op = &curop;
if ( !IS_PRIV(current->domain) )
return -EPERM;
So how do I make the IS_PRIV macro return non-zero for my domain_0 ,
ie. set d->is_privileged /...

[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh
Rathor at Oracle. The entirety of the design and development was done
by him; I have only reworked, reorganized, and simplified things in a
way that I think makes more sense. The vast majority of the credit
for this effort therefore goes to him. This version is labelled v13
because it is based on his most recent series, v11.

expose MWAIT to dom0
There''re basically two methods to enter a given C-state: legacy (hlt + I/O read),
and native(using mwait). MWAIT is always preferred when both underlying CPU
and OS support, which is a more efficient way to conduct C-state transition.
Xen PM relies on Dom0 to parse ACPI Cx/Px information, which involves one
step to notify BIOS about a set of capabilities supported by OSPM. One capability
