Global Control (GLPCI_CTRL)

1:0

PMODE0

Power Mode 0. Power mode for GLIU clock domain.

00: Disable clock gating. Clocks are always on.

01: Enable active hardware clock gating. Clock goes off whenever this module’s circuits

are not busy.

Description

63:60

FTH

In-Bound Flush Threshold. Controls the timing for requesting new read data while

concurrently flushing previously prefetched, stale read data. While flushing stale data, if

the number of prefetched 64-bit WORDs reaches this level, then a new read request is

made.

59:56

RTH

In-Bound Read Threshold. Controls the timing for prefetching read data. If the number

of prefetched 32-bit WORDs is decremented and reaches this threshold, a subsequent

GLIU request is generated to fetch the next cache-line of read data.

55:52

RSVD

(RO)

---

Reserved (Read Only). Returns 0.

51:49

RTL

Retry Transaction Limit. Limits the number of out-bound retries. If a target signals retry

indefinitely the PCI interface may be configured to abort the failing out-bound request.

000: No limit.

100: 64 retries.

001: 8 retries.

101: 128 retries.

010: 16 retries.

110: 256 retries.

011: 32 retries.

111: 512 retries.
