└─>HCCS driver on Kunpeng SoC
In linux kernel since version 4.14.327 (release Date: 2023-10-10)
The Huawei Cache Coherence System (HCCS) is a multi-chip
interconnection bus protocol.
The performance of application may be affected if some HCCS
ports are not in full lane status, have a large number of CRC
errors and so on.
Say M here if you want to include support for querying the
health status and port information of HCCS on Kunpeng SoC.
