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.
