Additionally, PSE may deadlock on transitions between sticky and non-sticky transmissions. There is also a credit drop issue observed when certain condition clocks are gated.</p> <p>work around these hardware errata by: - Disabling SQM sticky operation: - Clear TM6 (bit 15) - Clear TM11 (bit 14) - Disabling sticky → non-sticky transition path that can deadlock PSE: - Clear TM5 (bit 23) - Preventing credit drops by keeping the control-flow clock enabled: - Set TM9 (bit 21)</p> <p>These changes are applied via NIX_AF_SQM_DBG_CTL_STATUS. With this configuration the SQM/PSE maintain forward progress under load without credit loss, at the cost of disabling sticky optimizations.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>octeontx2-af: Workaround SQM/PSE stalls by disabling sticky</p> <p>NIX SQ manager sticky mode is known to cause stalls when multiple SQs share an SMQ and transmit concurrently.
