Register Trace Buffer (RTB)
|
|
|
|
The RTB is used to log discrete events in the system in an uncached buffer that
|
|
can be post processed from RAM dumps. The RTB must reserve memory using
|
|
the msm specific memory reservation bindings (see
|
|
Documentation/devicetree/bindings/arm/msm/memory-reserve.txt).
|
|
|
|
Required properties
|
|
|
|
- compatible: "qcom,msm-rtb"
|
|
- qcom,rtb-size: size of the RTB buffer in bytes
|
|
|
|
Optional properties:
|
|
|
|
- linux,contiguous-region: phandle reference to a CMA region
|
|
|
|
Example:
|
|
|
|
qcom,msm-rtb {
|
|
compatible = "qcom,msm-rtb";
|
|
qcom,rtb-size = <0x100000>;
|
|
};
