Just a knob to enable/disable the hotplug behavior without relying on the ACPI _STA.{PRES, ENA} Bits?
For what reason? Why would someone want to do this? Without a reason is pointless configurability that has to be tested.
The only reason I can fathom is "I don't trust my firmware - ignore its attempts to offline CPUs" ... but firmware can prevent them coming online in the first place, and eject-request is the one thing that does work on arm64 today (by accident). I think we can kick this down the road until someone has a strong reason for needing it.
Ok. Let us defer this discussion.
Maybe someone at KVM forum has a need for this - were you able to travel today? If so, what time will you be at the venue tomorrow to swap notes and produce a combined presentation. The slides I have are attached.
If not, were you able to pre-record a video ... or should I dramatically expand the material I have?!
In terms of testing, I've pinned down another problem now that _STA reports 'functional' from boot, but I've not published the branch yet.
Thanks,
James
