Add sysfs nodes to manage power of dGPU. Writing pci dev name to poweroff/poweron sysfs node powers off/on dGPU. The format of pci dev name is DDDD:BB:DD.F i.e. domain:bus:device.function echo 0001:01:00.0 > /sys/bus/pci/drivers/nvgpu/poweroff echo 0001:01:00.0 > /sys/bus/pci/drivers/nvgpu/poweron The permissions of nodes are set such that only root user can write to the sysfs node to control dGPU power state.
