DIVIL Register Descriptions (Continued)

5.6.1.2

GeodeLink Device Master Configuration MSR (DIVIL_GLD_MSR_CONFIG)

5.6.1.3

GeodeLink Device SMI MSR (DIVIL_GLD_MSR_SMI)

The flags are set by internal conditions. The internal conditions are enabled if the EN bit is 1. Reading the FLAG bit returns

the value; writing 1 clears the flag; writing 0 has no effect. (See Section 3.8.3 "MSR Address 2: SMI Control" on page 67 for

further SMI/ASMI generation details.)

Description

63:19

RSVD

Reserved. Reads return 0. Writes have no effect.

18:16

FIX_PREFETCH

Fixed Read Prefetch Policy.

000: None. Each read takes a complete trip to memory.

001: Initial read 08 bytes. Read next 8 only when requested.

010: Initial read 16 bytes. Read next 16 only when requested.

011: Initial read 32 bytes. Read next 32 only when requested.

100: Initial read 32 bytes. Read next 32 when 16 bytes left.

101, 110, and 111: Reserved.

15:14

DISCARD

Read Prefetch Discard Policy.

00: Reserved.

01: Discard all data not taken under current local bus grant.

10: Discard all data on any local bus transaction.

11: Discard all data on any local bus write transaction. Always use this value.

NON_COH_WR

Non-Coherent Write.

0: Write requests are coherent.

1: Write requests are non-coherent. Always use this value.

NON_COH_RD

Non-Coherent Read.

0: Read requests are coherent.

1: Read requests are non-coherent. Always use this value.

11:7

RSVD
