From 8fe633449f92d35b60a60de647a4e8fc1b5c8936 Mon Sep 17 00:00:00 2001 From: Seema Khowala Date: Thu, 9 Nov 2017 14:13:25 -0800 Subject: gpu: nvgpu: Add check_priv_security fuse ops -New fuse ops is added to set NVGPU_SEC_PRIVSECURITY and NVGPU_SEC_SECUREGPCCS bits in g->enabled_flags during hal initialization -For igpu non simulation platforms, fuses are read to decide if gpu should be allowed to boot or not. --Do not boot gpu if priv_sec_en is set but wpr_enabled is not set to 1 or vpr_auto_fetch_disable is not set to 0 --With priv_sec_en set, all falcons have to boot in LS mode and this needs wpr_enabled set to 1 AND vpr_auto_fetch_disable set to 0. In this case gmmu tries to pull wpr and vpr settings from tegra mc Bug 2018223 Change-Id: Iceaa1b0b3214e9a3d6cef5d77a82e034302f748b Signed-off-by: Seema Khowala Reviewed-on: https://git-master.nvidia.com/r/1595454 Reviewed-by: mobile promotions Tested-by: mobile promotions --- .../common/linux/vgpu/gp10b/vgpu_fuse_gp10b.h | 30 ++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 drivers/gpu/nvgpu/common/linux/vgpu/gp10b/vgpu_fuse_gp10b.h (limited to 'drivers/gpu/nvgpu/common/linux/vgpu/gp10b/vgpu_fuse_gp10b.h') diff --git a/drivers/gpu/nvgpu/common/linux/vgpu/gp10b/vgpu_fuse_gp10b.h b/drivers/gpu/nvgpu/common/linux/vgpu/gp10b/vgpu_fuse_gp10b.h new file mode 100644 index 00000000..2ec8f284 --- /dev/null +++ b/drivers/gpu/nvgpu/common/linux/vgpu/gp10b/vgpu_fuse_gp10b.h @@ -0,0 +1,30 @@ +/* + * Copyright (c) 2017, NVIDIA CORPORATION.
