Subject: Re: [PATCH v3 2/7] xsm: flask: change the dummy xsm policy and flask hook for map_gmfn_foregin

Message-ID: <CAHrd_jqno6h=x_AuZqQvxR6SBNCkOa_vqOE3MCBo=tX18ps4eA@mail.gmail.com> (raw)

Hi,
My current plan is to add the following new MAPSPACE to public/memory.h:
+#define XENMEMSPACE_gmfn_foreign_share 6 /* Same as *_gmfn_foreign, but this is
+ for a privileged dom to
+ shared pages between two doms. */
and create a corresponding entry xsm_map_gmfn_foreign_share to the
xsm structure, which will be filled with
the proposed policy.
Does this look good to you?
Cheers,
Zhongze Liu
