Subject: [PATCH v6 01/10] PCI/RCEC: Add RCEC class code and extended capability
Date: Tue, 22 Sep 2020 14:38:50 -0700 [thread overview]
Message-ID: <20200922213859.108826-2-seanvk.dev@oregontracks.org> (raw)
In-Reply-To: <20200922213859.108826-1-seanvk.dev@oregontracks.org>
From: Qiuxu Zhuo <qiuxu.zhuo@intel.com>
A PCIe Root Complex Event Collector(RCEC) has the base class 0x08,
sub-class 0x07, and programming interface 0x00. Add the class code
0x0807 to identify RCEC devices and add the defines for the RCEC
Endpoint Association Extended Capability.
See PCI Express Base Specification, version 5.0-1, section "1.3.4
Root Complex Event Collector" and section "7.9.10 Root Complex
Event Collector Endpoint Association Extended Capability"
