From 26b91946031a88293c7ce563ff923802af6509ce Mon Sep 17 00:00:00 2001 From: Deepak Goyal Date: Wed, 28 Feb 2018 16:39:57 +0530 Subject: gpu: nvgpu: gv11b: Correct PMU PG enabled masks. 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.
