Hi SAKTHIVEL,
Thank your for your response . On VM, added “intel_iommu=on” in
/boot/grub2/grub.cfg and rebooted the VM. Still getting the same issue
i.e., failed to start device. Here are the logs. I have done “export
ICP_SRIOV=0” to build driver without SRIOV. Please let me know if I am
missing anything.
[root at test1 QAT]# service qat_service start
Processing file: /etc/dh895xcc_qa_dev0.conf
ADF_CONFIG_CTL err: adf_set_bank_core_affinity: Invalid core affinity
settings for accelerator 0 bank 8. Max cpu number is 3. Defaulting to 0
ADF_CONFIG_CTL err: adf_set_bank_core_affinity: Invalid core affinity
settings for accelerator 0 bank 9. Max cpu number is 3. Defaulting to 0
Parity err reporting is disabled.
Error: failed to start device 0
There is 1 acceleration device(s) in the system:
icp_dev0 - type=dh895xcc, inst_id=0, node_id=0, bdf=00:05:0, #accel=6,
#engines=12, state=down
