| 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>; |
| }; |
