Qualcomm Technologies Inc. memory dump driver
|
|
|
|
QTI memory dump driver allows various client subsystems to register and
|
|
allocate respective dump regions. At the time of deadlocks or cpu hangs
|
|
these dump regions are captured to give a snapshot of the system at the
|
|
time of the crash.
|
|
|
|
Required properties:
|
|
|
|
-compatible: "qcom,mem-dump"
|
|
-memory-region: phandle to the CMA region. The size of the CMA region
|
|
should be greater than sum of size of all child nodes
|
|
to account for padding.
|
|
|
|
If any child nodes exist the following property are required:
|
|
|
|
-qcom,dump-size: The size of memory that needs to be allocated for the
|
|
particular node.
|
|
-qcom,dump-id: The ID within the data dump table where this entry needs
|
|
to be added.
|
|
|
|
Example:
|
|
|
|
mem_dump {
|
|
compatible = "qcom,mem-dump";
|
|
memory-region = <&dump_mem>;
|
|
|
|
rpmh_dump {
|
|
qcom,dump-size = <0x2000000>;
|
|
qcom,dump-id = <0xEC>;
|
|
};
|
|
};
