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. This may support for reducing system power
|
|
consumption if there are HCCS ports supported low power feature
|
|
on platform.
|
|
|
|
Say M here if you want to include support for querying the
|
|
health status and port information of HCCS, or reducing system
|
|
power consumption on Kunpeng SoC.
