Subject: x86/acpi/sleep: Provide registration for acpi_suspend_lowlevel.
|
||||
|
||||
Which by default will be x86_acpi_suspend_lowlevel.
|
||||
This registration allows us to register another callback
|
||||
if there is a need to use another platform specific callback.

|
||||
Subject: xen/acpi/sleep: Register to the acpi_suspend_lowlevel a callback.
|
||||
|
||||
We piggyback on "x86/acpi: Provide registration for acpi_suspend_lowlevel."
|
||||
to register a Xen version of the callback. The callback does not
|
||||
do anything special - except it omits the x86_acpi_suspend_lowlevel.
|
||||
It does that b/c during suspend it tries to save cr8 values (which
|
||||
the hypervisor does not support), and then on resume path the
|
||||
cr3, cr8, idt, and gdt are all resumed which clashes with what
|
||||
the hypervisor has set up for the guest.

resume
|
||||
|

Upon resume, it was found that ACPI C-states were missing from non-boot CPUs.
|

This change registers a syscore_ops handler for this case, and performs a
|
||||
subset of the xen_acpi_processor_init() functionality to achieve this case.
