We could discuss the virt CPU hotplug status/forward plan.
I don't know if Barry's scheduler discussion can benefit from an LOD session, please chime in if that's the case.
Hi Lorenzo, Thanks for asking. I have no important updates at this time. That discussion is mainly for co-working with Tim Chen on the plan of upstreaming and benchmarking, also figuring out whether the patches are leading to the same result on arm and x86 platforms.
Ok. So, anything else to discuss other than the PSCI KVM patches that are currently on ML ? Jonathan, Salil, anyone please do let me know.
On the near term horizon is the confidential compute stuff that there is an event about tomorrow, but next week feels a little early to try and have a detailed discussion about that (I assume)?
A few other things will surface by next month, but not next week ;)
Otherwise, nothing immediate jumps out to me, beyond any useful discussion that can be had around the PSCI KVM patches you mention.
Leaving that one aside, it seems the main open question from our side is around planning / progress on steps for the vCPU hotplug.
Perhaps that's something best formulated over email...
My current understanding is that next item would be the Guest Kernel changes? Perhaps a good target for sending out an RFC on that would be just after the merge window?
I am afraid we will have to rework the approach and implement this through ACPI only (kernel/spec changes) which is both good and bad news.
I am focusing on getting the ACPI specs agreed/changed in the Arm world, it will take me a while, hopefully I can expedite, that's all I can share here.
Next week I should be able to let you know what we are pursuing going forward, it is just to let you know that we are working on it to converge as soon as possible. The end result should not be massively different from Salil's initial work but there are lots of details we are vetting to make sure it is rock solid (and that everyone in the ARM world is happy with it, again, I can't share the fine grain details here).
Have a good week end, Lorenzo
