CC’ing Lyude Paul as she hooked up the clockgating support. Looking at the code, only NV40+ do have a therm engine. Therefore, shouldn’t nvkm_therm_clkgate_enable(), nvkm_therm_clkgate_fini() and nvkm_therm_clkgate_oneinit() all check for therm being not NULL, on top of their check for the clkgate_* hooks being there? Or instead, maybe have the check in nvkm_device_init() nvkm_device_init()? Pierre
