From 1ddcd0e6f03e83d0447f03ac57d5e0bda7a2f4c7 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Tue, 22 Jan 2019 20:49:31 -0300 Subject: [PATCH] kepler_compute: Fixup assert and rename engines When I originally added the compute assert I used the wrong documentation. This addresses that. The dispatch register was tested with homebrew against hardware and is triggered by some games (e.g. Super Mario Odyssey). What exactly is missing to get a valid program bound by this engine requires more investigation. --- src/video_core/CMakeLists.txt | 4 +-- src/video_core/engines/kepler_compute.cpp | 34 +++++++++++++++++++ .../{maxwell_compute.h => kepler_compute.h} | 31 +++++++++-------- src/video_core/engines/maxwell_compute.cpp | 28 --------------- src/video_core/gpu.cpp | 8 ++--- src/video_core/gpu.h | 6 ++-- 6 files changed, 59 insertions(+), 52 deletions(-) create mode 100644 src/video_core/engines/kepler_compute.cpp rename src/video_core/engines/{maxwell_compute.h => kepler_compute.h} (59%) delete mode 100644 src/video_core/engines/maxwell_compute.cpp diff --git a/src/video_core/CMakeLists.txt b/src/video_core/CMakeLists.txt index 33e507e69..1db0d031d 100644 --- a/src/video_core/CMakeLists.txt +++ b/src/video_core/CMakeLists.txt @@ -5,12 +5,12 @@ add_library(video_core STATIC debug_utils/debug_utils.h engines/fermi_2d.cpp engines/fermi_2d.h + engines/kepler_compute.cpp + engines/kepler_compute.h engines/kepler_memory.cpp engines/kepler_memory.h engines/maxwell_3d.cpp engines/maxwell_3d.h - engines/maxwell_compute.cpp - engines/maxwell_compute.h engines/maxwell_dma.cpp engines/maxwell_dma.h engines/shader_bytecode.h diff --git a/src/video_core/engines/kepler_compute.cpp b/src/video_core/engines/kepler_compute.cpp new file mode 100644 index 000000000..4ca856b6b --- /dev/null +++ b/src/video_core/engines/kepler_compute.cpp @@ -0,0 +1,34 @@ +// Copyright 2018 yuzu Emulator Project +// Licensed under GPLv2 or any later version +// Refer to the license.txt file included. + +#include "common/logging/log.h" +#include "core/core.h" +#include "core/memory.h" +#include "video_core/engines/kepler_compute.h" +#include "video_core/memory_manager.h" + +namespace Tegra::Engines { + +KeplerCompute::KeplerCompute(MemoryManager& memory_manager) : memory_manager{memory_manager} {} + +KeplerCompute::~KeplerCompute() = default;
