Thanks.
If Ian C is happy with the idl changes then I am happy with this
interface change for 4.2.
Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>
However I think patches 2 and 3 of your series come too late for the
4.2 freeze. Thanks for showing them to us, though. We should
reconsider them after 4.2.
Ian.

It's ok to wait until the 4.3 dev cycle.

Unfortunately "type" is a reserved word in ocaml (and possibly other
languages, which causes the bindings to fail to build:
make[4]: Entering directory `/local/scratch/ianc/devel/committer.git/tools/ocaml/libs/xl'
MLDEP
File "xenlight.ml", line 116, characters 2-6:

File "xenlight.mli", line 113, characters 28-31:

Ideally we'd make the bindings generator do appropriate substitutions on
keywords but the usual workaround is to s/type/kind for the field name.
BTW, I wasn't going to bounce the patch over this but could
LIBXL_VGA_INTERFACE_TYPE_DEFAULT not be part of the IDL definition of
the type? I'm not sure why we don't do the same for
LIBXL_TIMER_MODE_DEFAULT already.

Thanks for your review.
I didn't build against ocaml.
I 'make install' in tools/libxl directly.

Sorry, I'm not farmiliar with the vocabulary 'bounce',
do you mean s/type/kind is necessary or not?
I think you mean necessary, right?

do you mean this way below?
libxl_vga_interface_type = Enumeration("vga_interface_type", [
(-1, "DEFAULT"),
(0, "CIRRUS"),
(1, "STD"),
], init_val = "LIBXL_VGA_INTERFACE_TYPE_DEFAULT")
In my understanding, LIBXL_VGA_INTERFACE_TYPE_DEFAULT is not really
a meaningful vga type (even not present default vga to use, but just tag the
variable has never be initialized, so in meaningless state).
It's only used to check if libxl_vga_interface_type var is
initialized (whether stdvga setted by vm.cfg), to
avoid random value initialized.
It's equal with LIBXL_MEMKB_DEFAULT in this context.
It's the same with LIBXL_TIMER_MODE_DEFAULT

Yes, it is necessary.
By "bounce" I meant ask you to resubmit. IOW I wasn't going to ask you
to resubmit over the LIBXL_VGA_INTERFACE_TYPE_DEFAULT part, but I
figured since you needed to fix the ocaml stuff I would mention it.

Actually, looking at the definition of libxl_vga_interface_type you
should avoid using 0 as a real thing and then this becomes
libxl_vga_interface_type = Enumeration("vga_interface_type", [
(1, "CIRRUS"),
(2, "STD"),
])
Since the "default default" is 0 you can test for default just by
using !b_info.... here.
You'll notice that most other enums in the IDL have this property except
where the specific values come from elsewhere (like timer mode).
Several enums also include "UNKNOWN" as an explicit entry, which is much
the same as including "DEFAULT" IMHO.
> It's equal with LIBXL_MEMKB_DEFAULT in this context.
This is semantically a bit different to the enum case.
> It's the same with LIBXL_TIMER_MODE_DEFAULT
TIMER_MODE is not a good example to follow because the specific values
come from the hypervisor and libxl simple matches them.

I think this needs to be:
if (!xlu_cfg_get_long(config, "stdvga", &l, 0))
b_info->u.hvm.vga.kind = l ? \
LIBXL_VGA_INTERFACE_TYPE_STD : \
LIBXL_VGA_INTERFACE_TYPE_CIRRUS;
so that both "stdvga=0" and "stdvga=1" result in what the user asked for
without relying on the libxl default remaining CIRRUS.

IMHO, this make simple to be complex.
I think the check and set-default later in libxl_create.c as a whole is enough.
+ if (!b_info->u.hvm.vga.kind)
+ b_info->u.hvm.vga.kind = LIBXL_VGA_INTERFACE_TYPE_CIRRUS;
'as a whole' here, I means if more vga type added in the future, we
don't need to set the default
one by one, redundantly.

This is in libxl, as I said above xl should not rely on the default
remaining CIRRUS.
If the user says "stdvga=0" then xl needs to explicitly ask for CIRRUS,
despite the fact that it currently happens to be the default.
If we make the libxl default BLARGLE in the future then stdvga=0 still
needs to mean CIRRUS.
