Hi Michael:

Fortunately the ID element of ACPI in and of itself can be discussed in
public forum venues so no problem to copy the mailing list (added to cc for
this reply).

I don't know that naming a project that is not a legally identifiable entity
will cause an issue.  I just live in the school of not asking questions that
I don't know the answers to for this sort of thing as much as possible.  If,
for example, it would equally make sense to name a company (like say Red
Hat) or an incorporated organization (like say Linux Foundation) then I know
there's not going to be a question.  There _may_ be no question about name a
project as the owner; it's just an unknown so I wanted to bring that to your
attention -- I'm not sure what your urgency is and/or whether searching for
the absolute line of least resistance path matters to you or not.

If a guess OS is required to load QEMU-specific drivers for certain "soft"
devices to function correctly then I think your use case should not run us
into any hard questions.  I asked just to make sure, not being personally
familiar with the way QEMU works at that level.

In other words, I don't think there are problems here, I'm just trying to
make sure I know what to tell the review group (if anything) about a
slightly unusual request to minimize back-and-forth (I can't include the
qemu-devel mailing list on the Forum internal list review thread as that one
is in a UEFI Forum Confidential venue).

Just reply and let me know whether you want me to go ahead with the project
as the named owner or not and I can take it from there.

Cheers,
 
Mark.

We have discussed this on the project mailing list.

Everyone seems to be OK with simply making
Red Hat Inc. the owner of the "QEMU" ACPI ID.
Red Hat will own it on behalf of the community.

This should make things simpler as Red Hat is a legal
entity.

Exactly, OS needs this to load drivers for certain "soft" or
"para-virtual" devices.

To conclude, please simply register the ID "QEMU" for Red Hat inc.

[Qemu-devel] registering QEMU ACPI ID

[Michael S. Tsirkin]

Hello!
QEMU uses the ACPI Vendor ID "QEMU" in some of the ACPI tables
it generates. This is a bit of a spec violation:
all IDs must be registered with the ASWG.

>From the ASWG point of view, things are easier if a legal entity owns a
vendor ID, so Red Hat could ask to own the ID on behalf of the
community.

I intend to ask the ASWG to register this ID for Red Hat 2 weeks from
now, July 7th.

If anyone has questions or concerns, please speak now.

Thanks!

RedHat already officially "own" our PCI ID space (see
docs/specs/pci-ids.txt) so having them also deal with ACPI IDs
seems a reasonable plan to me.

Is the plan that we register "QEMU" as the vendor ID, or are the
ASWG likely to require a different ID string?

thanks

Yes, I'd like to register "QEMU" since we are already using it.
A bit less work for everyone involved.  It seems free at this point.

OK, no objections received, so I will now ask the acpi wg
to register "QEMU" to Red Hat.
