[Request] Regarding non-RFC patch-set of Virtual CPU Hotplug kernel support

by Salil Mehta

Hi James, Do we have any plan when we want to push the non-RFC Virtual CPU Hotplug patch-set for the kernel side to the community. I guess people will be more interested in reviewing if it is floated with a non-RFC tag. If time is a problem at your side then do you need my help in carrying it forward for you? Please let me know Thanks Salil.

Hello, We have been trying to verify the "system suspend/Restore" with vCPU Hotplug patches recently and found this functionality does not work on ARM64 with VMs even without our patches i.e. using latest kernel and qemu repository. estuary:/$ cat /sys/power/mem_sleep [s2idle] estuary:/$ estuary:/$ cat /sys/power/state freeze mem disk estuary:/$ estuary:/$ estuary:/$ echo mem > /sys/power/state [ 60.458445] PM: suspend entry (s2idle) [ 60.458840] Filesystems sync: 0.000 seconds [ 60.459649] Freezing user space processes [ 60.461149] Freezing user space processes completed (elapsed 0.001 seconds) [ 60.461830] OOM killer disabled.
