From 902fa4da52737d43e04c2a028658ad9840811a89 Mon Sep 17 00:00:00 2001 From: Tony Wasserka Date: Sat, 4 Apr 2015 12:57:31 +0200 Subject: Add CiTrace recording support. This is exposed in the GUI as a new "CiTrace Recording" widget. Playback is implemented by a standalone 3DS homebrew application (which only runs reliably within Citra currently; on an actual 3DS it will often crash still). --- src/citra_qt/CMakeLists.txt | 2 + .../debugger/graphics_breakpoint_observer.h | 2 +- src/citra_qt/debugger/graphics_tracing.cpp | 123 +++++++++++++++++++++ src/citra_qt/debugger/graphics_tracing.h | 27 +++++ src/citra_qt/main.cpp | 6 + 5 files changed, 159 insertions(+), 1 deletion(-) create mode 100644 src/citra_qt/debugger/graphics_tracing.cpp create mode 100644 src/citra_qt/debugger/graphics_tracing.h (limited to 'src/citra_qt') diff --git a/src/citra_qt/CMakeLists.txt b/src/citra_qt/CMakeLists.txt index d4c0cecc..47aaeca2 100644 --- a/src/citra_qt/CMakeLists.txt +++ b/src/citra_qt/CMakeLists.txt @@ -12,6 +12,7 @@ set(SRCS debugger/graphics_breakpoints.cpp debugger/graphics_cmdlists.cpp debugger/graphics_framebuffer.cpp + debugger/graphics_tracing.cpp debugger/graphics_vertex_shader.cpp debugger/profiler.cpp debugger/ramview.cpp @@ -35,6 +36,7 @@ set(HEADERS debugger/graphics_breakpoints_p.h debugger/graphics_cmdlists.h debugger/graphics_framebuffer.h + debugger/graphics_tracing.h debugger/graphics_vertex_shader.h debugger/profiler.h debugger/ramview.h diff --git a/src/citra_qt/debugger/graphics_breakpoint_observer.h b/src/citra_qt/debugger/graphics_breakpoint_observer.h index f0d3361f..02a0f4f4 100644 --- a/src/citra_qt/debugger/graphics_breakpoint_observer.h +++ b/src/citra_qt/debugger/graphics_breakpoint_observer.h @@ -13,7 +13,7 @@ * This is because the Pica breakpoint callbacks are called from a non-GUI thread, while * the widget usually wants to perform reactions in the GUI thread. */ -class BreakPointObserverDock : public QDockWidget, private Pica::DebugContext::BreakPointObserver { +class BreakPointObserverDock : public QDockWidget, protected Pica::DebugContext::BreakPointObserver { Q_OBJECT public: diff --git a/src/citra_qt/debugger/graphics_tracing.cpp b/src/citra_qt/debugger/graphics_tracing.cpp new file mode 100644 index 00000000..2e74193f --- /dev/null +++ b/src/citra_qt/debugger/graphics_tracing.cpp @@ -0,0 +1,123 @@ +// Copyright 2015 Citra Emulator Project +// Licensed under GPLv2 or any later version +// Refer to the license.txt file included. + +#include + +#include +#include +#include +#include +#include +#include + +#include "core/hw/gpu.h" +#include "video_core/pica.h" + +#include "nihstro/float24.h" + +#include "graphics_tracing.h" + +GraphicsTracingWidget::GraphicsTracingWidget(std::shared_ptr debug_context, + QWidget* parent) + : BreakPointObserverDock(debug_context, tr("CiTrace Recorder"), parent) { + + setObjectName("CiTracing"); + + QPushButton* start_recording = new QPushButton(tr("Start Recording")); + QPushButton* stop_recording = new QPushButton(QIcon::fromTheme("document-save"), tr("Stop and Save")); + QPushButton* abort_recording = new QPushButton(tr("Abort Recording")); + + connect(this, SIGNAL(SetStartTracingButtonEnabled(bool)), start_recording, SLOT(setVisible(bool))); + connect(this, SIGNAL(SetStopTracingButtonEnabled(bool)), stop_recording, SLOT(setVisible(bool))); + connect(this, SIGNAL(SetAbortTracingButtonEnabled(bool)), abort_recording, SLOT(setVisible(bool))); + connect(start_recording, SIGNAL(clicked()), this, SLOT(StartRecording())); + connect(stop_recording, SIGNAL(clicked()), this, SLOT(StopRecording())); + connect(abort_recording, SIGNAL(clicked()), this, SLOT(AbortRecording())); + + stop_recording->setVisible(false); + abort_recording->setVisible(false); + + auto main_widget = new QWidget; + auto main_layout = new QVBoxLayout; + { + auto sub_layout = new QHBoxLayout; + sub_layout->addWidget(start_recording); + sub_layout->addWidget(stop_recording); + sub_layout->addWidget(abort_recording); + main_layout->addLayout(sub_layout); + } + main_widget->setLayout(main_layout); + setWidget(main_widget); + + // TODO: Make sure to have this widget disabled as soon as emulation is started!
