Subject: [PATCH v1 04/13] xen/arm: add P2M type parameter in guest_physmap_add_pages
Date: Fri, 11 Mar 2022 14:11:14 +0800	[thread overview]
Message-ID: <20220311061123.1883189-5-Penny.Zheng@arm.com> (raw)
In-Reply-To: <20220311061123.1883189-1-Penny.Zheng@arm.com>

From: Penny Zheng <penny.zheng@arm.com>

In order to cover the scenario where users intend to set up guest
p2m foreign mapping with nr_pages, this commit adds a new P2M type
parameter in guest_physmap_add_pages.
