[XEN PATCH 0/2] Enumerate all allocated evtchns in lsevtchn

[Matthew Barnes <matthew.barnes@cloud.com>]

Currently, lsevtchn aborts its event channel enumeration when it hits
its first hypercall error, namely:
* When an event channel doesn't exist at the specified port
* When the event channel is owned by Xen

This results in lsevtchn missing potential relevant event channels with
higher port numbers.

This patch series adds the highest allocated event channel port for a
given domain in the xen_domctl_getdomaininfo hypercall struct, and uses
that value as an upper bound in the lsevtchn loop.

Matthew Barnes (2):
  xen/domctl: Add highest allocated evtchn port to getdomaininfo
  tools/lsevtchn: Use evtchn port upper bound for evtchn enumeration
