It has two Intel QAT devices. There are 32 VF devices available per QAT Device/DH895xCC device. I have assigned 4 QAT VFs to VM instance (Wind River Linux). On VM, 1) The # lspci -vvd: 443 command confirms that, these QAT VFs are not used by any kernel driver. 2) The #lsmod | grep qa also says that, no QAT driver is loaded. Did #echo "8086 0443" > /sys/bus/pci/drivers/igb_uio/new_id to bind all the available 4 VFs to the DPDK UIO driver. Thereafter triggered #lspci -vvd: 443 and found that none of the QAT VFs are bound to igb_uio kernel driver. The system log (#dmesg) shows that, probe failed for these devices. Can anyone please suggest what might be the underlying issue and its solution? Thank you in advance for your support and time. root@Local:/opt# dmesg -c [ 1979.178546] igb_uio: probe of 0000:00:06.0 failed with error -2 [ 1979.181698] igb_uio: probe of 0000:00:07.0 failed with error -2 [ 1979.184850] igb_uio: probe of 0000:00:08.0 failed with error -2 [ 1979.187997] igb_uio: probe of 0000:00:09.0 failed with error -2 root@Local:/opt# root@Local:/opt# lspci -vvd:443 00:06.0 Co-processor: Intel Corporation DH895XCC Series QAT Virtual Function Subsystem: Intel Corporation Device 0000 Physical Slot: 6 Control: I/O- Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR- TAbort- SERR- TAbort- SERR- TAbort- SERR-
