From 0cfb0bacb2581d79631f496afbc3a3d5dd19eb42 Mon Sep 17 00:00:00 2001 From: Markus Wick Date: Thu, 6 Sep 2018 15:48:08 +0200 Subject: [PATCH] video_core: Move command buffer loop. This moves the hot loop into video_core. This refactoring shall reduce the CPU overhead of calling ProcessCommandList. --- .../hle/service/nvdrv/devices/nvhost_gpu.cpp | 26 +++-- .../hle/service/nvdrv/devices/nvhost_gpu.h | 17 --- src/video_core/command_processor.cpp | 101 ++++++++++-------- src/video_core/command_processor.h | 17 +++ src/video_core/gpu.h | 4 +- 5 files changed, 86 insertions(+), 79 deletions(-) diff --git a/src/core/hle/service/nvdrv/devices/nvhost_gpu.cpp b/src/core/hle/service/nvdrv/devices/nvhost_gpu.cpp index 4cdf7f613..8e0f9a9e5 100644 --- a/src/core/hle/service/nvdrv/devices/nvhost_gpu.cpp +++ b/src/core/hle/service/nvdrv/devices/nvhost_gpu.cpp @@ -8,6 +8,7 @@ #include "core/core.h" #include "core/hle/service/nvdrv/devices/nvhost_gpu.h" #include "core/memory.h" +#include "video_core/command_processor.h" #include "video_core/gpu.h" #include "video_core/memory_manager.h" @@ -134,17 +135,16 @@ u32 nvhost_gpu::SubmitGPFIFO(const std::vector& input, std::vector& outp LOG_WARNING(Service_NVDRV, "(STUBBED) called, gpfifo={:X}, num_entries={:X}, flags={:X}", params.address, params.num_entries, params.flags);
