commit b7d6648d436fe0a99d4faf0f99c88a27a7bfea33
Author: Marek Marczykowski-Górecki <marmarek@invisiblethingslab.com>
Date: Tue Apr 14 04:37:04 2020 +0200
conf: add xen specific feature: e820_host
e820_host is a Xen-specific option, only available for PV domains, that
provides the domain a virtual e820 memory map based on the host one. It
is enabled with a new Xen hypervisor feature, e.g.
<features>
<xen>
<e820_host state='on'/>
</xen>
</features>
e820_host is required when using PCI passthrough and is generally
considered safe for any PV kernel. e820_host is silently ignored if set
in HVM domain configuration. See xl.cfg(5) man page in the Xen
documentation for more details.

tests: check conversion of passthrough hypervisor feature
Add a new test to check the 'mode' attribute of the passthrough element
and augment an existing, related test to check enablement of the
passthrough element only.

commit fadbaa23757ff9dca329bdb8d3447c27599f6884
Author: Jim Fehlig <jfehlig@suse.com>
Date: Wed Apr 15 16:34:54 2020 -0600
conf: add xen hypervisor feature 'passthrough'
'passthrough' is Xen-Specific guest configuration option new to Xen 4.13
that enables IOMMU mappings for a guest and hence whether it supports PCI
passthrough. The default is disabled. See the xl.cfg(5) man page and
xen.git commit babde47a3fe for more details.
The default state of disabled prevents hotlugging PCI devices. However,
if the guest configuration contains a PCI passthrough device at time of
creation, libxl will automatically enable 'passthrough' and subsequent
hotplugging of PCI devices will also be possible. It is not possible to
unconditionally enable 'passthrough' since it would introduce a migration
incompatibility due to guest ABI change. Instead, introduce another Xen
hypervisor feature that can be used to enable guest PCI passthrough
<features>
<xen>
<passthrough state='on'/>
</xen>
</features>
To allow finer control over how IOMMU maps to guest P2M table, the
passthrough element also supports a 'mode' attribute with values
restricted to snyc_pt and share_pt, similar to xl.cfg(5) 'passthrough'
setting .
