Subject: [PATCH v11 16/16] PCI/AER: Add RCEC AER error injection support
Date: Tue, 17 Nov 2020 11:19:54 -0800 [thread overview]
Message-ID: <20201117191954.1322844-17-sean.v.kelley@intel.com> (raw)
In-Reply-To: <20201117191954.1322844-1-sean.v.kelley@intel.com>
From: Qiuxu Zhuo <qiuxu.zhuo@intel.com>
Root Complex Event Collectors (RCEC) appear as peers to Root Ports and may
also have the AER capability.
Add RCEC support to the AER error injection driver.
