Hi Lorenzo, As a follow-up to our last meeting, do we have any updates from your internal discussions in regards to the support of ACPI based Virtual CPU Hotplug or its "possible" specification? :)
I am following up on it, should be able to give an update next LOD on Feb 22nd if that's OK.
Side note: I would be really grateful if we could run a CXL overview/sync-up on the Feb 22nd, given that the enablement code is being upstreamed.
Sure, though there are large parts of that which need figuring out yet even if current stuff is fine.
Jonathan

If we need to cover EU, US and Asia, I think the evening time for Asia is the only option, like 2pm(GMT)/10pm(GMT+8)/6am(GMT-8).
Or maybe we need to have two slots, one is Asia friendly and the other is US friendly.
Any preference?

I am UK based so the slot above is perfectly fine but others may disagree. We can have two separate calls, one for virt CPU hotplug and one for CXL, not sure though we have two completely disjoint sets of attendees.

We should probably move it to an afternoon slot GMT otherwise I don't think anyone in the US can attend (I know that an afternoon slot GMT is problematic for people in Asia, don't know how to solve this, please let me know).If we need to cover EU, US and Asia, I think the evening time for Asia

Hmm, it is difficult. Why not list the required key attendees first for each topic? Then we can select a proper time according to their time zones.

I think that we can keep the call on Feb 22nd scheduled as-is and have virt CPU hotplug *only* in the agenda (and maybe some back-up topics in case there is some time left).
I don't know if attendees in the US are interested in the virt CPU hotplug discussions though.
For CXL, JonathanC, JonM and I expressed interest maybe we can schedule a specific discussion CXL based in a slot that is more suitable for the US timezone on a separate date.

Sounds a good option. Please let me know the date/time after you figure it out, and I can help schedule the call.

We can have two separate calls, one for virt CPU hotplug and one for CXL, not sure though we have two completely disjoint sets of attendees.Hmm, it is difficult. Why not list the required key attendees first for
each
topic? Then we can select a proper time according to their time zones.
I think that we can keep the call on Feb 22nd scheduled as-is and have virt CPU hotplug *only* in the agenda (and maybe some back-up topics in case there is some time left).
I don't know if attendees in the US are interested in the virt CPU hotplug discussions though.
For CXL, JonathanC, JonM and I expressed interest maybe we can schedule a specific discussion CXL based in a slot that is more suitable for the US timezone on a separate date.
Sounds a good option. Please let me know the date/time after you figure it out, and I can help schedule the call.
Emails crossed - that works fine for us. I'm a bit curious who else might be interested from members. We can ping this one at LDCG as well, but lets not ask before we pick a time slot :)
I've still got some of the more recent changes to wade through and debug so not too soon please. 1-2 weeks+ should be fine.
My calender is looking fairly empty on Monday, Tuesday or Thursday afternoons towards the end of the month (Friday's probably also doable).

We should probably move it to an afternoon slot GMT otherwise I don't think anyone in the US can attend (I know that an afternoon slot GMT is problematic for people in Asia, don't know how to solve this, please let me know).If we need to cover EU, US and Asia, I think the evening time for Asia
is the
only option, like 2pm(GMT)/10pm(GMT+8)/6am(GMT-8).
Or maybe we need to have two slots, one is Asia friendly and the other
is US
friendly.
Any preference?
I am UK based so the slot above is perfectly fine but others may disagree. We can have two separate calls, one for virt CPU hotplug and one for CXL, not sure though we have two completely disjoint sets of attendees.
Hmm, it is difficult. Why not list the required key attendees first for each topic? Then we can select a proper time according to their time zones.
Whilst others will of course be interested, from Huawei side I can cover CXL - worth noting that I expect we are basically talking CXL 2.0 here not earlier. The stuff currently going on is focused on spec verification and preenablement for 2.0 (not a whole lot of hardware available yet - if there were we wouldn't be actively scrubbing the spec whilst implementing it)
1.1 and earlier more or less just look like normal devices or memory + some horrible impdef stuff in firmware. Might be room for some collaboration in EDK2 - unclear though. There will be device specific stuff, but a lot of that is impdef (how to do bias switching etc).
I'm guessing I'll do the intro slides for this one unless someone else wants to do the summary of current status / open questions bit? - more than happy to collaborate on it as well!
So for CXL Me + Huawei UK team members(GMT) If we got firmware heavy - perhaps not on first call on this topic - Henson (GMT + 8) Others from Huawei in China probably interested, though if time isn't great probably not 'that interested' at this stage.
From other members we clearly have Lorenzo + ARM team (GMT + others?) Jon Masters (GMT - 5 I think)
Whilst I don't mind anyone from other interested companies (e.g. Intel) showing up, I suspect that would make limited sense at a first discussion of this topic?
CPU HP like to be more interesting to my China based colleagues alongside the UK team. So if we do go with a late slot for China rather than split meeting, let's do that topic first.
As to whether we want to split the meeting, that depends on whether we expect a detailed discussion on this occasion, or more of an update on direction followed by watch this space. Lorenzo any idea yet on which category we might be in?

Perhaps we could do them as a unified call (late time slot for China) on the basis that we can have a follow up call on vCPU HP if it appears necessary (after people have had time to digest what you share etc).

Hi,
I noticed the call on Monday is still scheduled at 10GMT, is that final ?
I'd need to know since I am asking other Arm folks to join, please let me know.
I think it is useful to send out a separate email with the calls details before the end of the week.
Thank you very much.

It does for me, thanks a lot. Lorenzo
Hi Lorenzo,
I have adjusted the meeting time to 2pm (GMT) on the Collaborate page. I will send out a separate email specific for this meeting after I get back to office tomorrow.
Regards, Jammy

Hi,
I noticed the call on Monday is still scheduled at 10GMT, is that final ?
I'd need to know since I am asking other Arm folks to join, please let me know.
I think it is useful to send out a separate email with the calls details before the end of the week.
Thank you very much.
Lorenzo

I hope and work towards a virt CPU hotplug session that provides a finalized way forward (that is, what to do to upstream it rather than discussing how CPU hotplug should be implemented), which means I expect it to be fairly short - that's why I thought that CXL can be part of the same slot.
Perhaps we could do them as a unified call (late time slot for China) on the basis that we can have a follow up call on vCPU HP if it appears necessary (after people have had time to digest what you share etc).
Would that work for everyone?
It won't be that short after all, the call on Monday is scheduled at 10 GMT, is that final ?
https://collaborate.linaro.org/display/LOD/Linaro+Open+Discussions+Home
I would like to ask some people from Arm to attend so that we can work towards a solution for virtual CPU HP, I understand it is holiday season in China but I would like to finalize the date/time asap please.
I also would like to ask if there are some pointers I can contact to attend the call from kubernetes/containers guys who were interested in this piece of work.
We can start a new thread if that makes things simpler.
Thanks ! Lorenzo
