I have been also testing this and I found the bugs that is causing this: $ oc logs -c intel-qat-initcontainer intel-qat-plugin-6p2pf -n openshift-operators | grep -B5 -A5 sym /usr/local/bin/qat-init.sh: line 44: echo: write error: Invalid argument <--------------------------------------------- Device f7:00.0 configured with services: dc /usr/local/bin/qat-init.sh: line 44: echo: write error: Invalid argument Device f3:00.0 configured with services: sym;asym

---

when checking the script: line 44: echo "$SERVICES_ENABLED" > "$DEVPATH"/qat/cfg_services

It is trying to write the updated configuration from user to the device by the write fails.

I have tried to use a different kernel module as specified in Intel's Doc but could not find a suitable one: Only 4xxxvf

oc apply -f 004-qat-device-plugin-cr.yaml The QatDevicePlugin "qatdeviceplugin-sample" is invalid: spec.kernelVfDrivers[0]: Unsupported value: "402xx": supported values: "4xxxvf"

oc apply -f 004-qat_device_plugin-orig.yaml The QatDevicePlugin "qatdeviceplugin-sample" is invalid: spec.kernelVfDrivers[0]: Unsupported value: "401xx": supported values: "4xxxvf"

even doing it manually does not work

bash-5.1# echo sym > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services bash: echo: write error: Invalid argument

Full test:

[root@master-0 ~]# echo -n down > /sys/bus/pci/devices/0000:f3:00.0/qat/state [root@master-0 ~]# echo -n dc > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services [root@master-0 ~]# echo -n asym > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services -bash: echo: write error: Invalid argument [root@master-0 ~]# echo -n asym;sym > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services asym-bash: sym: command not found [root@master-0 ~]# echo -n 'asym;sym' > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services -bash: echo: write error: Invalid argument [root@master-0 ~]# echo -n 'sym;asym' > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services [root@master-0 ~]# echo -n 'sym;dc' > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services -bash: echo: write error: Invalid argument [root@master-0 ~]# echo -n 'asym;dc' > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services -bash: echo: write error: Invalid argument [root@master-0 ~]# echo -n 'dc;asym' > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services -bash: echo: write error: Invalid argument [root@master-0 ~]# echo -n 'dc;sym' > /sys/bus/pci/devices/0000:f3:00.0/qat/cfg_services -bash: echo: write error: Invalid argument [root@master-0 ~]#

so in OCP 4.14 with QAT operator 0.28 ; It is only possible to set dc or sym;asym default : when no ServicesEnabled is set ; "qat.intel.com/cy": "16", "qat.intel.com/dc": "16" when set dc "qat.intel.com/cy": "0", "qat.intel.com/dc": "32" when set sym;asym "qat.intel.com/cy": "32", "qat.intel.com/dc": "0"
