repo sync 时注意到qcacld,去看了下代码
https://source.codeaurora.org/quic/la/platform/vendor/qcom-opensource/wlan/qcacld-2.0/tree/
qcacld 应该是指Qualcomm Atheros Cross-Layer Design，有本书叫Improving the Performance of Wireless LANs 详细介绍了此技术的细节。
注意到WCNSS : Wireless Connectivity Subsystem,通过搜索看到了lwn上的记录
记录提到此驱动是remoteproc，解释:https://www.kernel.org/doc/Documentation/remoteproc.txt
lwn上此架构的引申参考Introducing a generic AMP framework
