-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 <seemaj@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1595454 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
