Enabling "debugging" and "profiling" in a L40S vGPU

Hello,

I have installed GRID driver in a system with a L40S. I have got vGPUs, but if I create a virtual machine assigning a profile (from a virtual function), I have got only vGPUs type A, B and Q, but not C (for CUDA purposes). So my question is how could I get that “C” profiles?

I have read in documentation PDF that I must stop virtual machine. If I try to run “echo” to the $mdev device to enable debugging and profiling, the folders not exists and I can write to “vgpu_params” file…

Could anyone help me?

Thanks.
