[dts] DDP / testpmd setup

[Sebastian Foss]

Hi Rami,

I found the switch for testpmd to use a cmd line script instead of using interactive mode. Still need to see if loading a ddp persists on the card when rebinding the i40e driver instead of vfio / uio.

The kernel i40e driver also seems to have the functions to use AdminQ to load DDPs onto the card – however im not sure how to do it from userland.

Hi Sebastian,

I don't know of such a way, unfortunately. Also you cannot automate testpmd

as it is to load the profile automatically without going interactive mode.

Hi,

we are using testpmd to store ddp profiles in an Intel X710DA2 NIC. Is there a way to have those profiles stored in the NIC permanently – or what would be the best solution to have those profiles loaded automatically at boot and use a regular kernel driver afterwards ? From what i understand so far to use the DPDK functions to load a DDP Profile the UIO or VFIO drivers have to be used.

 

Thank you!
