Hi,
Is there a way to know the support plans for CXL protocol in QEMU?
I see that there is side branch development going on:

https://gitlab.com/bwidawsk/qemu/-/tree/cxl-2.0v2

But when does it get merged and gets released in QEMU formally?
Is there a way to know a rough timeline?

Regards,
Prashant

You should rather the authors of that repository whether and when they plan
to contribute their changes to the QEMU project. It's certainly not going to
happen automatically that these patches get merged into the main repository.

Worth noting that they have posted an RFC, so I would suggest replying to
that thread to make sure you get all the right people.

I haven't posted v2 yet because I have a few more changes I wanted to make
before doing so, however v2 has all of Jonathan's feedback plus a few minor
things.

Thomas, it's been CC'd to a few folks outside of the list itself, but I couldn't
get much in the way of reviewers. Advice on that is welcome.

Maybe add some more people on CC: who are familiar with x86? See the
MAINTAINERS file and look for "86" in there...

 HTH,

Thanks.

I think the relevant maintainers have already been Cc'd. There isn't any
specific connection to x86, I've only enabled it for x86 because that's all I've
had time for at the moment.

At this stage, eyes from PCI devs is probably what's most important.
