I am new in the intel SPDK and meet some problem when I run the example code.
I setup the BIOS as this page said.
Intel® Hyper-Threading Technology off
Intel SpeedStep® technology enabled
Intel® Turbo Boost Technology disabled
then I git clone from this page and run all the command. The test command ./test/unit/unittest.sh return All unit tests passed.
But when I run the example examples/ioat/verify/verify , it return
EAL: 24 hugepages of size 1073741824 reserved, but no mounted hugetlbfs found for that size
Starting SPDK v18.10-pre / DPDK 18.05.0 initialization…
[ DPDK EAL parameters: verify –no-shconf -c 0x1 –legacy-mem –file-prefix=spdk_pid3170 ]

Not enough ioat channels found. Check that ioat channels are bound to uio_pci_generic or vfio-pci. scripts/setup.sh can help with this.
and scripts/setup.sh status shows

My hardware is:
linux kernel version 4.15.7 with ioatdma compile as module
CPU intel Xeon E5-2695
chipset C612
It would be great help if somebody could give me some advises or send me some website about SPDK! Thank you!

Answer
Run ./scripts/setup.sh (with no parameters). If there will be no ioat devices under I/OAT DMA section you can’t run this app. Also there is no hugetlbfs mount points.
