Subject: [PATCH] hw/acpi: Update GED _EVT method AML with cpu scan
|
|
|
|
OSPM evaluates _EVT method to map the event. The cpu hotplug event eventually
|
|
results in start of the cpu scan. Scan figures out the cpu and the kind of
|
|
event(plug/unplug) and notifies it back to the guest.
|
|
|
|
The change in this patch updates the GED AML _EVT method with the call to
|
|
\\_SB.CPUS.CSCN which will do above.
