Subject: [PATCH] PCI: ACPI: Fix ThunderX PEM initialization
Date: Mon, 30 Jan 2017 08:25:52 -0800 [thread overview]
Message-ID: <1485793552-12614-1-git-send-email-Vadim.Lomovtsev@caviumnetworks.com> (raw)
This patch is to address PEM initialization issue
which causes network issues.
It is necessary to search for _HID:PNP0A08 while requesting
PEM resources via ACPI instead of "THRX0002".
