hello i have this error here, do you know how i can solve it?
what does “no PMD support for SFT” mean?

Hey there. Normally that’s due to the SF (and the representor) are not in trusted mode.

https://docs.nvidia.com/doca/sdk/scalable-functions/index.html It’s in Step 2. Prerequisites

mlxreg -d /dev/mst/mt41686_pciconf0 --reg_id 0xc007 --reg_len 0x40 --indexes "0x0.0:32=0x80000000" --yes --set "0x4.0:32=0x1"

This will only affect SFs that are created after the command is entered. That means you have to either delete/recreate the SF, or create another SF and use that one.

The way we set trusted/untrusted mode for the SFs will be changing in the upcoming DOCA 1.2 release.
