* Qualcomm Krait L1 / L2 cache dumping device
|
||
|
|
This is a virtual device that dumps the contents of L1 and L2 caches in the
|
||
|
|
event of a kernel panic or a watchdog trigger.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "qcom,cache_dump"
|
||
|
|
- qcom,l1-dump-size: Amount of memory needed for L1 dump(s), in bytes
|
||
|
|
- qcom,l2-dump-size: Amount of memory needed for L2 dump, in bytes
|
||
|
|
- qcom,memory-reservation-size: Combined reserved memory for the dump buffers
|
||
|
|
- qcom,memory-reservation-type: Type of memory to be reserved
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- qcom,use-imem-dump-offset: If specified, store cache dump buffer addresses
|
||
|
|
in IMEM rather than using the memory dump reservation table.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
qcom,cache_dump {
|
||
|
|
compatible = "qcom,cache_dump";
|
||
|
|
qcom,l1-dump-size = <0x100000>;
|
||
|
|
qcom,l2-dump-size = <0x400000>;
|
||
|
|
qcom,memory-reservation-type = "EBI1";
|
||
|
|
qcom,memory-reservation-size = <0x500000>;
|
||
|
|
};
