Subject: [PATCH V8 8/8] docs/specs/acpi_hw_reduced_hotplug: Add the CPU Hotplug Event Bit
Date: Tue, 12 Mar 2024 02:00:00 +0000 [thread overview]
Message-ID: <20240312020000.12992-9-salil.mehta@huawei.com> (raw)
In-Reply-To: <20240312020000.12992-1-salil.mehta@huawei.com>
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.
