GeodeLink™ Interface Unit Register Descriptions
6.1
The GeodeLink™ Interface Unit (GLIU) registers are Model
Specific Registers (MSRs) and are accessed through the
RDMSR and WRMSR instructions. The MSR address is
derived from the perspective of the CPU Core. See Section
4.2 "MSR Addressing" on page 59 for more details.
The MSRs are split into the following groups:
• Standard GeodeLink Device (GLD) MSRs
• P2D Descriptor MSRs
