From cc4b9f540f66abc9f60cf9f8e2217ff17349bc77 Mon Sep 17 00:00:00 2001 From: Mahantesh Kumbar Date: Tue, 13 Feb 2018 14:37:18 +0530 Subject: gpu: nvgpu: PMU super surface support - Added ops "pmu.alloc_super_surface" to create memory space for pmu super surface - Defined method nvgpu_pmu_sysmem_surface_alloc() to allocate pmu super surface memory & assigned to "pmu.alloc_super_surface" for gv100 - "pmu.alloc_super_surface" set to NULL for gp106 - Memory space of size "struct nv_pmu_super_surface" is allocated during pmu sw init setup if "pmu.alloc_super_surface" is not NULL & free if error occur. - Added ops "pmu_ver.config_pmu_cmdline_args_super_surface" to describe PMU super surface details to PMU ucode as part of pmu command line args command if "pmu.alloc_super_surface" is not NULL. - Updated pmu_cmdline_args_v6 to include member "struct flcn_mem_desc_v0 super_surface" - Free allocated memory for PMU super surface in nvgpu_remove_pmu_support() method - Added "struct nvgpu_mem super_surface_buf" to "nvgpu_pmu" struct - Created header file "gpmu_super_surf_if.h" to include interface about pmu super surface, added "struct nv_pmu_super_surface" to hold super surface members along with rsvd[x] dummy space to sync members offset with PMU super surface members.
