* gpu: nvgpu: gv11b: Correct PMU PG enabled masks.Deepak Goyal2018-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | PMU ucode records supported feature list for a particular chip as support mask sent via PMU_PG_PARAM_CMD_GR_INIT_PARAM. It then enables selective feature list through enable mask sent via PMU_PG_PARAM_CMD_SUB_FEATURE_MASK_UPDATE cmd. Right now only ELPG state machine mask was enabled. Only ELPG state machine was getting executed but other crucial steps in ELPG entry/exit sequence were getting skipped. Bug 200392620. Bug 200296076.

* gpu: nvgpu: Fix race in PMU state transitions.Deepak Goyal2017-10-25
| | | | | | | | | | | | | | | | | | | | | PMU response(intr callback for messages) can run faster than the kthread posting commands to PMU. This causes the PMU message callback to skip important pmu state change(which happens just after the PMU command is posted). Solution: State change should be triggered from only inside the intr callback. Other places can only update the pmu_state variable. This change also adds error check to print in case command post fails.

* 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.
