Subject: [PATCH v7 13/13] PCI/AER: Add RCEC AER error injection support
Date: Wed, 30 Sep 2020 14:58:20 -0700	[thread overview]
Message-ID: <20200930215820.1113353-14-seanvk.dev@oregontracks.org> (raw)
In-Reply-To: <20200930215820.1113353-1-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.
