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
