Hi,

While running "event_crypto_adapter_autotest" the crash is observed when below
sriov configuration are done on the board. But if sriov configuration are not
done then crash is not observed for the crypto autotest.


modprobe vfio-pci

#Get pci-bdf for qat device
CPMDEV=$(lspci | grep "578a" | cut -f1 -d
echo $CPMDEV

echo "/sys/bus/pci/devices/0000:${CPMDEV}:00.0/sriov_numvfs"

echo "Before update, sriov_numvfs = \c"
cat /sys/bus/pci/devices/0000:${CPMDEV}:00.0/sriov_numvfs;

echo 10 > /sys/bus/pci/devices/0000:${CPMDEV}:00.0/sriov_numvfs

echo "After update, sriov_numvfs = \c"
cat /sys/bus/pci/devices/0000:${CPMDEV}:00.0/sriov_numvfs;

lsmod
if [ ! -z ${RDK_INSTALL+x} ]; then
        cd $RDK_INSTALL/dpdk/usertools
else
        cd $RTE_SDK/usertools
fi
