SYSTEM PM VIOLATORS
System PM Violoators is a virtual device sends a QMP message to AOP to start
recording subsystems that are preventing system low power modes - AOSS sleep,
CX PC, DDR low power from happening during a test duration. The stats are
saved in MSGRAM and are read and displayed from Linux in debugfs.
PROPERTIES
- compatible:
Usage: required
Value type: <string>
Definition: must have "qcom,sys-pm-violators". Additionally, the SoC
specific compatible must be specified.
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: The address on the AOP Message RAM from where the stats
are read.
- mbox:
Usage: required
Value type: <phandle>
Definition: handle to the QMP mailbox.
The second argument, channel is always '0'.
EXAMPLE
sys-pm-vx@c320000 {
compatible = "qcom,sys-pm-violators", "qcom,sys-pm-lahaina";
reg = <0xc320000 0x0400>;
mboxes = <&qmp_aop 0>;
mbox-names = "aop";
