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,memory-reservation-size: size of reserved memory for the RTB buffer
|
|
- qcom,memory-reservation-type: type of memory to be reserved
|
|
(see memory-reserve.txt for information about memory reservations)
|
|
|
|
Example:
|
|
|
|
qcom,msm-rtb {
|
|
compatible = "qcom,msm-rtb";
|
|
qcom,memory-reservation-type = "EBI1";
|
|
qcom,memory-reservation-size = <0x100000>; /* 1M EBI1 buffer */
|
|
};
