Thermal Sensor
The EP80579 has an on-die thermal sensor. It helps to control the silicon temperature
by monitoring the silicon thermal status and activating the thermal control sequence
when the silicon reaches its maximum operating temperature. See Chapter 50.0,
“Thermal Specifications and Design Considerations” for details.
ACPI Implementation
The PCI device tree for the EP80579 is shown in Figure 3-4, “Overview of PCI
infrastructure for On-die Devices” on page 121. The EP80579 follows the ACPI
specification (http://www.acpi.info/DOWNLOADS/ACPIspec30a.pdf) which implies that
all the PCI devices implement the standard PCI/ACPI registers:
1. PCI Power Management Block
2. Capability ID
3. Next Item Pointer
4. Power Management Capabilities (PMC)
5. Power Management Control and Status Register (PMCSR)
