Subject: [PATCH 2/2] ACPI: NUMA: show match info about PXM ID and offline/online node
Date: Fri, 15 Mar 2019 10:19:40 +0800 [thread overview]
Message-ID: <20190315021940.86905-3-wangkefeng.wang@huawei.com> (raw)
In-Reply-To: <20190315021940.86905-1-wangkefeng.wang@huawei.com>
It maybe trigger some issue when the acpi device driver allocs memory
from an offline node, so use alternative acpi_map_pxm_to_online_node()
to find an online node, let's show infomation about proximity ID, mapped
offline node and the nearest online node returned.
