I have the issue when loading nouveau with runpm=0 set, that further nouveau loads without runpm set or runpm=1 don't put the card into sleep state. This is caused by calling pm_runtime_get_sync in drm_device.unload when the usage_counter isn't 0. pm_runtime_get_sync always increases the suage_counter and so the usage_counter gets increased allthough runpm=0 is set, meaning nouveau leaves the device with a +1 usage_counter after unload. This patch fixes that allowing me to load nouveau later with runpm=1 so, that the device is put into sleep state. --- drm/nouveau/nouveau_drm.c | 3 ++- 1 fil...
