From 863b47064445b3dd5cdc354821c8d3d14deade33 Mon Sep 17 00:00:00 2001 From: Mahantesh Kumbar Date: Mon, 10 Sep 2018 21:11:49 +0530 Subject: gpu: nvgpu: PMU init sequence change -Moved PMU RTOS init & start RTOS from acr_gm20b.c file pmu.c method nvgpu_init_pmu_support() -Modified nvgpu_init_pmu_support() to init required interface for PMU RTOS & does start PMU RTOS in secure & non-secure based on NVGPU_SEC_PRIVSECURITY flag. -Created secured_pmu_start ops under PMU ops to start PMU falcon in low secure mode. -Updated PMU ops update_lspmu_cmdline_args, setup_apertures & secured_pmu_start assignment for gp106 & gv100 to support modified PMU init sequence. -Removed duplicate PMU non-secure bootstrap code from multiple files & defined gm20b_ns_pmu_setup_hw_and_bootstrap()method to handle non secure PMU bootstrap, reused this method for need chips.
