Subject: [PATCH v6 10/10] PCI/AER: Add RCEC AER error injection support
Date: Tue, 22 Sep 2020 14:38:59 -0700	[thread overview]
Message-ID: <20200922213859.108826-11-seanvk.dev@oregontracks.org> (raw)
In-Reply-To: <20200922213859.108826-1-seanvk.dev@oregontracks.org>

From: Qiuxu Zhuo <qiuxu.zhuo@intel.com>

The Root Complex Event Collectors(RCEC) appear as peers to Root Ports
and also have the AER capability. So add RCEC support to the current AER
error injection driver.
