6.8 Video Processor Register Descriptions
This section provides information on the registers associ-
ated with the Video Processor: Standard GeodeLink
Device (GLD) and Video Processor Specific MSRs
(accessed via the RDMSR and WRMSR instructions), and
two blocks of functional memory mapped registers (Video
Processor and Flat Panel).
Table 6-75 through Table 6-78 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.
For memory offset mapping details, see Section
4.1.3 "Memory and I/O Mapping" on page 47.
