MSM BIMC bandwidth monitor device
|
|
|
|
bimc-bwmon is a device that represents the MSM BIMC bandwidth monitors that
|
|
can be used to measure the bandwidth of read/write traffic from the BIMC
|
|
master ports. For example, the CPU subsystem sits on one BIMC master port.
|
|
|
|
Required properties:
|
|
- compatible: Must be "qcom,bimc-bwmon", "qcom,bimc-bwmon2" or
|
|
"qcom,bimc-bwmon3"
|
|
- reg: Pairs of physical base addresses and region sizes of
|
|
memory mapped registers.
|
|
- reg-names: Names of the bases for the above registers. Expected
|
|
bases are: "base", "global_base"
|
|
- interrupts: Lists the threshold IRQ.
|
|
- qcom,mport: The hardware master port that this device can monitor
|
|
- qcom,target-dev: The DT device that corresponds to this master port
|
|
|
|
Example:
|
|
qcom,cpu-bwmon {
|
|
compatible = "qcom,bimc-bwmon";
|
|
reg = <0xfc388000 0x300>, <0xfc381000 0x200>;
|
|
reg-names = "base", "global_base";
|
|
interrupts = <0 183 1>;
|
|
qcom,mport = <0>;
|
|
qcom,target-dev = <&cpubw>;
|
|
};
