[Xen-devel] [PATCH v2 0/5] xen/arm: event channels and shared_info page

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,
this patch series implements support for injecting event channels into
the guest and enables a wider range of hypercalls for ARM guests.

In order to allow more flexibility I modified the hypercall protocol, in
particular the hypercall number is not passed as imm to hvc anymore,
because we might not always know it at compile time.
The hypercall number is now passed on the r12 register.

With this the corresponding Linux patch series applied to both Linux and
Xen, I am able to boot dom0, start xenstored and run basic xl commands,
like "xl list" and "xl uptime".



Changes in v2:

- fixed tabs/spaces problem.



Stefano Stabellini (5):
      arm: shared_info page allocation and mapping
      arm: implement vcpu_mark_events_pending
      arm: set the default dom0 max_vcpus value to 1 (currently is 0)
      arm: use r12 to pass the hypercall number
      arm: introduce more hypercalls
