Last Modified: Sep 13, 2023

Affected Product(s):

Opened: Nov 18, 2015

Severity: 3-Major


Some hardware platforms provide insufficient diagnostic information in the hsb_snapshot to determine the problem the system encounters. (The hsb_snapshot command gathers information from the high speed bridge (HSB) for diagnostic purposes.) Additional HSB debug registers are needed to perform full diagnostics.


Some HSB debug registers are needed to provide full diagnostics.


Running the hsb_snapshot command in the qkview utility.



Fix Information

The hsb_snapshot now supports all HSBE2 PDE/MGMT_RING, etc., debug and XLMAC registers, to support a more robust diagnostic operations.
