Hi,
I am just getting started with BlueField-2 and DOCA and trying to run the example applications.
I am trying to create a Virtual Function by following the documentation on:
NVIDIA DOCA Virtual Functions User Guide
However, I am stuck at step #3 of chatper 2: Prerequisites which says to set the VFs to trusted mode by running this command on the DPU:
$ mlxreg -d /dev/mst/mt41686_pciconf0 --reg_id 0xc007 --reg_len 0x40 --indexes "0x0.0:32=0x80000000" --yes --set "0x4.0:32=0x1"
as the previous command fails with the following output:
root@ktdpu:~# mlxreg -d /dev/mst/mt41686_pciconf0 --reg_id 0xc007 --reg_len 0x40 --indexes "0x0.0:32=0x80000000" --set "0x4.0:32=0x1"
You are about to send access register id: 0xc007 with the following data:

Do you want to continue ? (y/n) [n] : y
Sending access register...
