[Xen-devel] [PATCH v2 0/4] 32-bit domU PVH support

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

Changes in v2:
* Only set domain's has_32bit_shinfo, not is_32bit_pv. This adds patch 1 that
  replaces some of is_pv_32bit_domain()/is_pv_32bit_vcpu()/is_pv_32on64_vcpu()
  tests with has_32bit_shinfo().
  Note that I only replaced what I thought was necessary to boot the guest.
  MCA and tracing might also need similar changes (and maybe something else)
* Set up PVH VCPUs for 64-bit mode (i.e. keep setup the way it is now) and
  change mode to 32-bit later if necessary. (patch 2)
* Minor cleanup in hvm_do_hypercall() (patch 3)
* Drop 2 patches (one that set vstart address to __HYPERVISOR_COMPAT_VIRT_START
  and the other that became unnecessary due to the first change above)

Initial 32-bit PVH support, dom0 will need more work.

Boris Ostrovsky (4):
  x86/compat: Test whether guest has 32b shinfo instead of being a PV
    32b domain
  x86/pvh: Set 32b PVH guest mode in XEN_DOMCTL_set_address_size
  x86/pvh: Handle hypercalls for 32b PVH guests
  libxc/x86/pvh: Allow creation of 32b PVH guests
