Telemetry Aggregator

The Telemetry Aggregator serves as an architectural and discoverable interface to hardware telemetry:

  • Standardized PCIe discovery solution that enables software to discover and manage telemetry across products

  • Standardized definitions for telemetry decode, including data type definitions

  • Exposure of commonly used telemetry for power and performance debug including:

    • P-State status, residency and counters

    • C-State status, residency and counters

    • Energy monitoring

    • Device state monitoring (for example, PCIe L1)

    • Interconnect/bus bandwidth counters

    • Thermal monitoring

Exposure of SoC state snapshot for atomic monitoring of package power states, uninterrupted by software that reads.

The Telemetry Aggregator is also a companion to the CrashLog feature where data is captured about the SoC at the point of a crash. These counters can provide insights into the nature of the crash.
