273 Lane Select Function Is Not Available for Link BIST on 8-Bit

HyperTransport™ Links In Ganged Mode

Description

The link BIST engine incorrectly initiates tests on sublink 1 rather than sublink 0 under the following

conditions:

• The HyperTransport™ link is configured as an 8-bit link in ganged mode,

• LaneSel[1], F0x[18C:170][13], is set to 1b,

• BistEn, F0x[18C:170][10], is set to 1b, and

• BIST is initiated by assertion of warm reset or a LDTSTOP_L disconnect.

Potential Effect on System

No impact to normal operational mode; however, the lane select function is not available for testing

asymmetric links or isolation of errors to the uplink or downlink on symmetric links.

Suggested Workaround

None.

Fix Planned

Yes
