- The power device node is created at bootime and the power node is used to power-on the GPU. Power node is commmon for MIG and non-MIG platforms. As the same API is used for power and other MIG/non-MIG nodes, we need to distinguish between them. Otherwise the same nodes creation will give boot issue. - As we are supporting mig_mode setting for non-mig platforms like GV11B, the condition need to be added to create MIG-modes or not. If any mig-mode is set on gv11b/tu104 then graphics pipeline will be disabled.
