Subject: [PATCH 6/9] cpus: Call hotplug handlers in DeviceWire()
Date: Tue, 28 Jan 2025 15:21:49 +0100 [thread overview]
Message-ID: <20250128142152.9889-7-philmd@linaro.org> (raw)
In-Reply-To: <20250128142152.9889-1-philmd@linaro.org>
To call the hotplug handlers with REALIZED vCPU, we can
use the DeviceWire handler.
