From 1df31e4b65633a1264c55e8e1a4162036b260c18 Mon Sep 17 00:00:00 2001 From: Fernando Sahmkow Date: Wed, 25 Sep 2019 19:43:23 -0400 Subject: GPU_Async: Correct fences, display events and more. This commit uses guest fences on vSync event instead of an articial fake fence we had. It also corrects to keep signaling display events while loading the game as the OS is suppose to send buffers to vSync during that time. --- src/video_core/gpu_thread.cpp | 14 +------------- 1 file changed, 1 insertion(+), 13 deletions(-) (limited to 'src/video_core/gpu_thread.cpp') diff --git a/src/video_core/gpu_thread.cpp b/src/video_core/gpu_thread.cpp index 5f039e4fdc..d7048b6ae7 100644 --- a/src/video_core/gpu_thread.cpp +++ b/src/video_core/gpu_thread.cpp @@ -5,8 +5,6 @@ #include "common/assert.h" #include "common/microprofile.h" #include "core/core.h" -#include "core/core_timing.h" -#include "core/core_timing_util.h" #include "core/frontend/scope_acquire_window_context.h" #include "video_core/dma_pusher.h" #include "video_core/gpu.h" @@ -68,14 +66,10 @@ ThreadManager::~ThreadManager() { void ThreadManager::StartThread(VideoCore::RendererBase& renderer, Tegra::DmaPusher& dma_pusher) { thread = std::thread{RunThread, std::ref(renderer), std::ref(dma_pusher), std::ref(state)}; - synchronization_event = system.CoreTiming().RegisterEvent( - "GPUThreadSynch", [this](u64 fence, s64) { state.WaitForSynchronization(fence); }); } void ThreadManager::SubmitList(Tegra::CommandList&& entries) { - const u64 fence{PushCommand(SubmitListCommand(std::move(entries)))}; - const s64 synchronization_ticks{Core::Timing::usToCycles(std::chrono::microseconds{9000})}; - system.CoreTiming().ScheduleEvent(synchronization_ticks, synchronization_event, fence); + PushCommand(SubmitListCommand(std::move(entries))); } void ThreadManager::SwapBuffers(const Tegra::FramebufferConfig* framebuffer) { @@ -102,10 +96,4 @@ u64 ThreadManager::PushCommand(CommandData&& command_data) { return fence; } -MICROPROFILE_DEFINE(GPU_wait, "GPU", "Wait for the GPU", MP_RGB(128, 128, 192)); -void SynchState::WaitForSynchronization(u64 fence) { - while (signaled_fence.load() < fence) - ; -} - } // namespace VideoCommon::GPUThread -- cgit v1.2.3
