QAT heartbeat with autoreset

SSant31 — Tue, 12 Nov 2019 12:29:43 GMT

Hello,

I enabled QAT autoreset on error and configured the QAT driver with "--enable-icp-hb-fail-sim" option. I noticed the following when I tried to test with "heartbeat_sim_fail".

======================================

# cat /sys/kernel/debug/qat_dh895xcc_0000\:03\:00.0/heartbeat_sim_fail

dh895xcc 0000:03:00.0: adf_heartbeat_simulate_failure for random AE 9, thr 9

# cat /sys/kernel/debug/qat_dh895xcc_0000\:03\:00.0/heartbeat

-1

dh895xcc 0000:03:00.0: ERROR: QAT is not responding.

dh895xcc 0000:03:00.0: Quiescing device.

dh895xcc 0000:03:00.0: Disable arbiter.
