10.3. Using DPDK

The Ifpga Rawdev driver continually monitors the critical sensors mentioned in Table 14. If the critical sensor thresholds are exceeded while the DPDK software is running, then the DPDK software stops with an error message. For example: Run the testpmd with the server fan turned off.
 sudo ./x86_64-native-linuxapp-gcc/app/testpmd -l 0,1,2,3,4,5,6,7 -n 4 \
--vdev 'ifpga_rawdev_cfg0,ifpga=15:00.0,port=0' -- -i --no-numa

testpmd > set_surprise_link_check_aer(): Set AER, pls graceful shutdown
>>>>>>Set AER 0,0 3ff030,31c1
EAL: Error - exiting with code: 1
Cause: >>>>>>Graceful Shutdown

You must power cycle the server to ensure complete functionality of the board is restored.
