Adaptive Data Collection Practices in a Multi-Processor Device

A method for a slave processor in a multi-processor device to adapt its information collecting practices based on a power state of a master processor in the multi-processor device, the method comprising:

• receiving an indication that the master processor is operating in a first power state;
• collecting information relating to operation of the slave processor according to a first information collecting mode based on the indication that the master processor is operating in the first power state;
• receiving an indication that the master processor is operating in a second power state;
• collecting information relating to operation of the slave processor according to a second information collecting mode based on the indication that the master processor is operating in the second power state;
• and
• storing the collected information in a buffer.

A method for a master processor of a multi-processor device to facilitate adaptive information collecting practices for a slave processor of the multi-processor device based on a power state of the master processor, the method comprising:

• transitioning between at least two power states;
• providing indications of transitions between the at least two power states to the slave processor, wherein the slave processor operates in a different power domain than the master processor, wherein the indications are configured to enable the slave processor to transition between at least two information collecting modes based on a current power state of the master processor;
• receiving indications to retrieve information collected by the slave processor;
• and
• retrieving the information collected by the slave processor based on the indications to retrieve the information collected by the slave processor.
