Subject: [Qemu-devel] [PATCH-for-4.2 v9 02/12] hw/acpi: Do not create memory hotplug method when handler is not defined
Date: Tue, 13 Aug 2019 22:05:29 +0100 [thread overview]
Message-ID: <20190813210539.31164-3-shameerali.kolothum.thodi@huawei.com> (raw)
In-Reply-To: <20190813210539.31164-1-shameerali.kolothum.thodi@huawei.com>
From: Samuel Ortiz <sameo@linux.intel.com>
With Hardware-reduced ACPI, the GED device will manage ACPI
hotplug entirely. As a consequence, make the memory specific
events AML generation optional. The code will only be added
when the method name is not NULL.
