[PATCH V7 8/8] docs/specs/acpi_hw_reduced_hotplug: Add the CPU Hotplug Event Bit
Posted by Salil Mehta via 1 year ago
GED interface is used by many hotplug events like memory hotplug, NVDIMM hotplug
and non-hotplug events like system power down event. Each of these can be
selected using a bit in the 32 bit GED IO interface. A bit has been reserved for
the CPU hotplug event.
