* gpu: nvgpu: fix pmu state change for dgpu bootPeter Daifuku2017-08-16
| | | | | | | | | | | | | | | | | | | | In pmu_handle_pg_elpg_msg, when processing ELPG_MSG_DISALLOW_ACK, if current pmu state is ELPG_BOOTING and GR_POWER_GATING is not supported, make sure nvgpu_pmu_state_change updates the state_change flag, since PMU is now fully initialized. In particular, this fixes PMU boot for dgpu, which does not support GR_POWER_GATING.

* gpu: nvgpu: Remove unnecessary use of ACCESS_ONCE()Terje Bergstrom2017-08-04
| | | | | | | | | | | | | | | ACCESS_ONCE() is used for making sure that in a given place of code access a variable exactly once. It prevents compiler rearranging the read from happening earlier. Remove its use from cases where rearranging of the read does not create problems.
