Datasheet Volume Two: Functional Description, February 2014
Intel® Xeon® Processor E7-2800/4800/8800 v2 Product Family has two Home Agents:
HA0 and HA1. Device 14 registers address HA0, while Device 28 registers address HA1.
The registers in Device 14 and Device 28 are identical.
13.3.1 Device 14, 28 Function 0
13.3.1.1 TMBAR
This is the base address for the Thermal Controller Memory Mapped space. There is no
physical memory within this 32 KB window that can be addressed. The 32 KB reserved
by this register does not alias to any PCI 2.2 compliant memory mapped space.

Thermal Memory Map Base Address (TMMBA):
This field corresponds to bits 31 to 15 of the base address TMBAR address
space.
BIOS will program this register resulting in a base address for a 32KB block of
contiguous memory address space. This register ensures that a naturally
aligned 32KB space is allocated within total addressable memory space.
