Subject: [PATCH v3 10/10] PCI/AER: Add RCEC AER error injection support
Date: Wed, 12 Aug 2020 09:46:59 -0700 [thread overview]
Message-ID: <20200812164659.1118946-11-sean.v.kelley@intel.com> (raw)
In-Reply-To: <20200812164659.1118946-1-sean.v.kelley@intel.com>
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.
