Re: [Xen-devel] High CPU temp, suspend problem - xen 4.1.5-pre, linux 3.7.x




3. ACPI C-states are only present for CPU0 (after resume of course), fixed by
"xen: Re-upload processor PM data to hypervisor after S3" patch by Ben, but it
isn't in upstream linux (nor Konrad's acpi-s3 branches).
I don't recall seeing any ACK / NAK from Konrad on this.

Original post:
https://patchwork.kernel.org/patch/2033981/

Konrad - do you have any thoughts about incorporating this into a
future merge window?

Hey Ben,
I seem to have missed it.
I think the patch is missing a change to pr_backup->acpi_id = i, otherwise it would resend the C-states with the same APIC ID. Also the upstream version does kfree(pr_backup) at some point.

But more importantly, do you know why it is needed? Is Xen hypervisor "loosing" this information because they go offline and then they are onlined again?
