Subject: [PATCH v5 0/3] xen/balloon: fixes for memory hotplug
Date: Tue, 1 Sep 2020 10:33:23 +0200 [thread overview]
Message-ID: <20200901083326.21264-1-roger.pau@citrix.com> (raw)
Hello,
The following series contain some fixes in order to split Xen
unpopulated memory handling from the ballooning driver using the
ZONE_DEVICE functionality, so that physical memory regions used to map
foreign pages are not tied to memory hotplug.
Note this is currently only available for x86 due to Arm using an
identity map for dom0 p2m and thus needing special handling.
Thanks, Roger.
