GLIU Register Descriptions

4.2 GLIU Register Descriptions
All GeodeLink™ Interface Unit (GLIU) registers are Model
Specific Registers (MSRs) and are accessed through the
RDMSR and WRMSR instructions.
The registers associated with the GLIU are the Standard
GeodeLink Device (GLD) MSRs, GLIU Specific MSRs.
GLIU Statistic and Comparator MSRs,
P2D Descriptor
MSRs, and I/O Descriptor MSRs. The tables that follow are
register summary tables that include reset values and page
references where the bit descriptions are provided.
Note: The MSR address is derived from the perspective
of the CPU Core. See Section 4.1 "MSR Set" on
page 45 for more details on MSR addressing.
Reserved (RSVD) fields do not have any meaningful stor-
age elements. They always return 0.
