[SPDK] Building spdk on CentOS6

Hi,


Finally got to looking at support of spdk build on CentOS6, things look good, except for one issue.

spdk is latest 18.01.x version, dpdk is 16.07 (+3 dpdk patches to allow compilation) and some minor patches (mainly some memory configuration stuff), kernel is a patched 4.9.6.


build succeeded except for the usage of the dpdk function pci_vfio_is_enabled.

I had to apply the patch bellow, removing the usage of this function and then compilation completed without any issues.


It seems that I am missing some sort of dpdk configuration as I see that the function is built, but not packaged into the generated archive.


I went back to square one and ran the instructions in http://www.spdk.io/doc/getting_started.html, but I see no mention of dpdk there. Actually the ./configure requires it.


My next step is to use a more recent dpdk, but shouldn't this work with my version? Am I missing some dpdk configuration?

BTW, as we are not using vhost, on our 17.07 version we simply use CONFIG_VHOST=n in order to skip this, but I would be happier if we used a better solution.

P.S. Here is the patch to remove use of this function:
