Subject: [PATCH 2/2] xen: Kconfig: nest Xen guest options
Date: Wed, 14 Oct 2020 13:53:41 -0400 [thread overview]
Message-ID: <20201014175342.152712-3-jandryuk@gmail.com> (raw)
In-Reply-To: <20201014175342.152712-1-jandryuk@gmail.com>
Moving XEN_512GB allows it to nest under XEN_PV. That also allows
XEN_PVH to nest under XEN as a sibling to XEN_PV and XEN_PVHVM giving:
[*] Xen guest support
[*] Xen PV guest support
[*] Limit Xen pv-domain memory to 512GB
[*] Xen PV Dom0 support
[*] Xen PVHVM guest support
[*] Xen PVH guest support
