[PATCH 00/10] soc/arm64: qcom: Add LLCC BWMON on SDM845

Posted by Krzysztof Kozlowski 3 years, 9 months ago

Hi,

Description
===========
BWMON is a data bandwidth monitor providing throughput/bandwidth over certain
interconnect links in a SoC.  It might be used to gather current bus usage and
vote for interconnect bandwidth, thus adjusting the bus speed based on actual
usage.

Qualcomm SoCs might several BWMON instances.  Extend existing support for CPU
BWMON (called v4) to LLCC BWMON (called v5).

Best regards,
Krzysztof
