Display Controller Register Descriptions

This section provides information on the registers associ-
ated with the Display Controller (DC) (i.e., GUI and VGA
blocks), including the Standard GeodeLink™ Device (GLD)
MSRs and the Display Controller Specific MSRs (accessed
via the RDMSR and WRMSR instructions). Table 6-45
through Table 6-50 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.
