xen/acpi: add xen acpi processor driver
Xen hypervisor need parsed acpi processor info for CPU Cx/Px power
so this patch introduces xen acpi processor driver to parse the acpi info,
and notify the hypervisor upon receiving the info.
This patch has two components:
- driver/acpi/processor_xen.c: implement the xen acpi processor driver
- drivers/xen/acpi_processor.c: provide the interface to notify Xen
adds it in the 2.6.32 tree?
It looks like the commit in question is actually this one, from March
My search didn't find it because the files don't use the string
The important thing that I missed on my end was not having the ACPI
processor driver selected (for some reason). I had cpufreq and ACPI
enabled, but I needed that, as well.
