All GeodeLink Devices have the following Standard MSRs
and are always located at the addresses indicated below
from the base address given in Table 4-2 "MSR Addresses
from AMD Geode™ GX Processor" on page 60:
• MSR Address 0: GeodeLink Device Capabilities
• MSR Address 1: GeodeLink Device Master Configura-
• MSR Address 2: GeodeLink Device System Manage-
• MSR Address 3: GeodeLink Device Error Control
• MSR Address 4: GeodeLink Device Power Management
• MSR Address 5: GeodeLink Device Diagnostic MSR
4.8.1
The Capabilities MSR (GLD_MSR_CAP) is read only and
provides identification information as illustrated Table 4-7.

The defined fields in the GeodeLink Device Master Config-
uration MSR (GLD_MSR_CONF) vary depending upon the
device. Refer to the appropriate GeodeLink Device register
chapter starting in Section 6.0 "Register Descriptions" on
page 199 for descriptions.
4.8.3
Each GeodeLink Device within the Geode CS5535 com-
panion device incorporates System Management Inter-
rupts (SMIs). These SMIs are controlled via the Standard
GLD_MSR_SMI located at MSR Address 2 within each
GeodeLink Device (see Table 4-8). The lower 32 bits of
this register contain Enable (EN) bits, while the upper 32
bits contain Flag (FLAG) bits. The EN and FLAG bits are
organized in pairs of (n, n+32). For example: (0,32); (1,33);
(2,34); etc. The GLD_MSR_SMI is used to control and
report events.
An event is any action or occurrence within the GeodeLink
Device requiring processor attention. The FLAG bits are
status bits that record events. The EN bits enable events to
be recorded. An EN bit must be 1 for an event to be
recorded (with the exception of the GLUI and the GLCP -
the EN bit must be 0 for an event to be recorded). When an
event is recorded, the associated FLAG bit is set to a 1.
SMI events are of two types: Asynchronous SMI (ASMI)
and Synchronous SMI (SSMI).
