ARM CPU memory latency monitor device
arm-memlat-mon is a device that represents the use of the PMU in ARM cores
to measure the parameters for latency driven memory access patterns.
Required properties:
- compatible: Must be "qcom,arm-memlat-mon"
- qcom,cpulist: List of CPU phandles to be monitored in a cluster
- qcom,target-dev: The DT device that corresponds to this master port
- qcom,core-dev-table: A mapping table of core frequency to a required bandwidth vote at the
given core frequency.
Example:
qcom,arm-memlat-mon {
compatible = "qcom,arm-memlat-mon";
qcom,cpulist = <&CPU0 &CPU1>;
qcom,target-dev = <&memlat0>;
qcom,core-dev-table =
< 300000 1525>,
< 499200 3143>,
< 1881600 5859>;
};
