[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.

[Question] System suspend/resume functionality on ARM64 VM does seem to be working?

by Salil Mehta

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.
