| 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>; |
| }; |
| }; |
