Hi all,

I want to implement shared memo= ry mechanism between two mini-os. I started by implementing the example &qu= ot;4.5. Exercise: Sharing Memory between VMs" of the book "The De= finitive Guide to Xen Hypervisor" . I have included the necessary file= s, but when I compile =C2=A0"offering.c", it gives this error:

error: incompatible types when assigning to typ= e =E2=80=98__guest_handle_ulong=E2=80=99 from type =E2=80=98struct grant_en= try_t *=E2=80=99
=C2=A0 =C2=A0 =C2=A0setup_op.frame_list =3D gran= t_table;


If I use casting for= grant_table, like implementing this way:
setup_op.frame_list =3D= (XEN_GUEST_HANDLE(ulong))grant_table;

The err= or will be:

Rather read the rest of the source code to know how it's done :)=

arch/arm/mm.c:=C2=A0 =C2=A0 set_xen_guest_handle(setup.frame_list, fra= mes);
arch/x86/mm.c:=C2=A0 =C2=A0 set_xen_guest_handle(setup.frame_list, fra= mes);

Those look like a good way to do it :)

That being said, the comment for GNTTABOP_setup_table says

=C2=A0 =E2=80=9CXen may not support more than a single grant-table page per= domain.=E2=80=9D

I don't know if that's still true. Mini-os does set up its own
grant-table, so you may not be able to set up your own.

As a matter of fact, you don't actually need to: ./include/gnttab.h
should already be giving you an interface to grant access to pages to
other domains.

Samuel

Rather read the rest of the source code to know how it's done :)=

arch/arm/mm.c:=C2=A0 =C2=A0 set_xen_guest_handle(setup.frame_list, fra= mes);
arch/x86/mm.c:=C2=A0 =C2=A0 set_xen_guest_handle(setup.frame_list, fra= mes);

Those look like a good way to do it :)

That being said, the comment for GNTTABOP_setup_table says

=C2=A0 =E2=80=9CXen may not support more than a single grant-table page per= domain.=E2=80=9D

I don't know if that's still true. Mini-os does set up its own
grant-table, so you may not be able to set up your own.

As a matter of fact, you don't actually need to: ./include/gnttab.h
should already be giving you an interface to grant access to pages to
other domains.

Well, simply as I mentioned:

set_xen_guest_handle(setup.frame_list, frames);

i.e. instead of makign a direct assignment, pass to set_xen_guest_handle the setup_op.frame_list as first argument, and the pointer to set to it
as second argument.

But again, I believe you don't want to set a grant table yourself, and<= br> rather just use include/gnttab.h's functions: call gnttab_grant_access<= br> to grant access, and gnttab_end_access to end the grant. That'll drop basically 2/3 of what you wrote :)

Indeed, the frame_list field of gnttab_setup_table wants the list of=
pfns for the grant table, not the pointer to the grant table itself.

There is no other step needed.=C2=A0 See examples of uses within min= i-os,
e.g. pcifront.c, you just give the domid, the frame number, whether r/w
or r/o, and you get th reference to pass to the friend domU.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 char shared_buffer[PAGE_SIZE];

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gref =3D gnttab_grant_access(DOMID_FRIEND,= virt_to_pfn(&shared_buffer), 0);

then pass gref to the other domain, e.g. through xenstore.

The other domain can then map it:

=C2=A0 =C2=A0 =C2=A0 =C2=A0 struct gntmap map;
=C2=A0 =C2=A0 =C2=A0 =C2=A0 uint32_t domid =3D DOMID_ORIGIN;
=C2=A0 =C2=A0 =C2=A0 =C2=A0 void *addr;

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gntmap_init(&map);
=C2=A0 =C2=A0 =C2=A0 =C2=A0 addr =3D gntmap_map_grant_refs(&map, 1, &am= p;domid, 0, &gref, 0);



and at the end,

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gntmap_munmap(&map, addr, 1);
=C2=A0 =C2=A0 =C2=A0 =C2=A0 gntmap_fini(&map);

and in the origin domain,

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gnttab_end_transfer(gref);

Dear Samuel,
I tried to =C2=A0compile a sample program= but I was not able, because it does not know gref, should I pass it someho= w?
Do you have any hello word =C2=A0sample of offering and= mapping especially for mini-os?
I am so thankful.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 char shared_buffer[PAGE_SIZE];

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gref =3D gnttab_grant_access(DOMID_FRIEND,= virt_to_pfn(&shared_buffer), 0);

then pass gref to the other domain, e.g. through xenstore.

The other domain can then map it:

=C2=A0 =C2=A0 =C2=A0 =C2=A0 struct gntmap map;
=C2=A0 =C2=A0 =C2=A0 =C2=A0 uint32_t domid =3D DOMID_ORIGIN;
=C2=A0 =C2=A0 =C2=A0 =C2=A0 void *addr;

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gntmap_init(&map);
=C2=A0 =C2=A0 =C2=A0 =C2=A0 addr =3D gntmap_map_grant_refs(&map, 1, &am= p;domid, 0, &gref, 0);



and at the end,

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gntmap_munmap(&map, addr, 1);
=C2=A0 =C2=A0 =C2=A0 =C2=A0 gntmap_fini(&map);

and in the origin domain,

=C2=A0 =C2=A0 =C2=A0 =C2=A0 gnttab_end_transfer(gref);

See for instance blkfront.c:

dev->ring_ref =3D gnttab_grant_access(dev->dom,virt_to_mfn(s),0)= ;

it then writes it to xenstore:

err =3D xenbus_printf(xbt, nodename, "ring-ref","%u", d= ev->ring_ref);

and at the end, ends access:

gnttab_end_access(dev->ring_ref);


and for the mapping part, see tpmback.c:

page =3D gntmap_map_grant_refs(&gtpmdev.map, 1, &domid, 0, &am= p;ringref, PROT_READ | PROT_WRITE)

and

gntmap_munmap(&gtpmdev.map, (unsigned long)tpmif->page, 1);

Samuel
