Subject: [RFC PATCH v3 4/9] hw/arm/virt: Initialize the present cpu members
Date: Sun, 16 May 2021 18:28:55 +0800 [thread overview]
Message-ID: <20210516102900.28036-5-wangyanan55@huawei.com> (raw)
In-Reply-To: <20210516102900.28036-1-wangyanan55@huawei.com>
We create and initialize a cpuobj for each present cpu in
machvirt_init(). Now we also initialize the cpu member of
structure CPUArchId for each present cpu in the function.
This will be used to determine whether a cpu is present
when generating ACPI tables in later patches.
