With Generic Power Domains (genpd), bpmp driver will manage the GPU powergating. With the nvgpu idle/unidle flows updated for VPR with genpd/RPM, the usage of the below tegra bpmp calls can be removed from nvgpu from railgate APIs for t186 and t194. Note that genpd is available in k4.14 onwards, so this will work on current downstream kernel. tegra_bpmp_running tegra_powergate_is_powered tegra_powergate_partition tegra_unpowergate_partition Runtime suspended state indicates that the device is railgated. Update the t186 and t194 is_railgated handlers with this. t210 railgate/unrailgate will be still managed by nvgpu as bpmp support is not present.
