CPU Subsystem Dump Driver
|
|
|
|
The CPU Subsystem dump driver is used to dump various hardware entities
|
|
like the instruction and data tlbs or the unified tlbs etc. to an
|
|
allocated buffer. This allows the data to be analysed in case of corruption.
|
|
|
|
Required Properties for the cpuss_dump node:
|
|
-compatible = "qcom,cpuss-dump";
|
|
|
|
All child nodes of cpuss_dump node are interpreted as the various hardware
|
|
entities which need to be dumped.
|
|
|
|
Required properties of the dump nodes
|
|
|
|
- qcom,dump-node: phandle to the acutal cpuss hardware entity present
|
|
in the cpu map
|
|
- qcom,dump-id: The ID within the data dump table where this entry needs to
|
|
be added.
|
|
|
|
Example:
|
|
msm_cpuss_dump {
|
|
compatible = "qcom,cpuss-dump";
|
|
qcom,itlb_dump100 {
|
|
qcom,dump-node = <&L1_itlb_100>;
|
|
qcom,dump-id = <34>;
|
|
};
|
|
};
