[PATCH v2 0/6] raisin: introduce ovmf and linux

[Stefano Stabellini]

Hi all,

this patch series includes a few clean-ups and introduces a component to
build ovmf and a component to build a linux kernel. The latter is not
enabled by default, and could probably benefit from a bit more work on
the kconfig options to really be useful, but it is a start.

Changes in v2:
- rename _verbose_echo to verbose_echo
- add "raisin: pass --with-system-seabios with seabios was built"
- only enable ovmf in Xen, if we actually have built ovmf


Stefano Stabellini (6):

      raisin: pass --with-system-seabios with seabios was built
      raisin: introduce ovmf

For this and the following ovmf if we didn't build seabios/ovmf here
then you pass nothing, which will result in xen.git downloading and
doing things itself, is that what is wanted? I think, although I confess
I'm not sure and I haven't checked, you can pass --without-thing to
avoid this and to disable the support (which might hopefully result in
clearer error messages to the user down the line).

This is a good point. I don't know what we want exactly here.

In the case of OVMF if you don't specify anything the default in Xen is
not to build it.
In the case of Seabios if you don't specify anything the default is
clone and build.

Do we want to be absolutely sure to avoid any cloning from the
xen-unstable tree with raisin?
Or do we simply want to fall back to the default behaviour?

I think that both a reasonable answers, I am leaning toward avoiding any
cloning always. This also means disabling stubdoms.  What do you think?

I think this makes sense. If a users wants ovmf they should ask for it
via raisin, if they don't then they won't get it.

Is the plan to eventually have raisin build stubdoms itself?

Well I think what people will expect is that if they disable seabios
from ENABLED_COMPONENTS, that it won't be enabled, not that it will
still be built but by Xen instead.

I think it's reasonable to expect users to do some clean-up if they
change their mind about what they want to build.  (I wonder if we could
use a "./raise distclean", which will rm -rf dist, as well as all
components in series but not in COMPONENTS.)

Re stubdoms, I think that we should let the xen component do it until
it's possible to do it out of tree (i.e., no regression in functionality).

Yes, I think it would make sense for raisin to build them.

OK

On the other hands current stubdoms are not even tested in osstest, so
we might as well wait for the next generation to be ready before having
them in raisin.

They are at least build tested.

And George's point about "no regression in functionality" (i.e. for
users, not test systems) is a strong one.

Unless you were suggesting to leave them to xen.git for now?

I don't really get the logic here.  But it is true that we shipped 4.5
with qemu stubdomains broken and hardly anyone noticed for what, a
month?

Yes, this is what I was referring to.

The logic is that they are not tested, they are not enabled by default,
and in their current form they get in the way of getting rid of all git
cloning in xen-unstable. I would rather disable them until we get them
properly in raisin.
