There was some discussion about updating to Qt6 and I figured I would
work on some smaller parts. For Windows platform the WinMain function has moved
from the Qt5::WinMain to a new one called Qt6::EntryPointPrivate
Also Qt5 supports versionless CMake targets
https://www.qt.io/blog/versionless-cmake-targets-qt-5.15
These other changes in this commit are to support Qt6, but in ways that don't mess with Qt5.
src/yuzu/bootmanager.cpp: Qt6 complains about not being able to know to use QPoint or QPointF, picking QPoint
src/yuzu/bootmanager.h: Qt6 prefers that QStringList.h be included rather than an empty class definition
src/yuzu/configuration/configure_system.cpp: toULongLong intends to return unsigned 64 bit integer, but
Settings::values.rng_seed is only 32 bits wide
src/yuzu/game_list.cpp: Qt6 returns a different datatype for QStringList.length than Qt5,
it used to be int, but in Qt6 its now qsizetype
src/yuzu/loading_screen.cpp: Qt5's for QStyleOption.init say to switch to initFrom.
The QStyleOption.init doesn't exist in Qt6
src/yuzu/main.cpp: Another QPointer and QStringList.size, lets standardize on size()
Use its std::stop_token to abort shader cache loading.
Using std::stop_token instead of std::atomic_bool allows the usage of
other utilities like std::stop_callback.
EmuWindow::PollEvents was called from the GPU thread (or the CPU thread
in sync-GPU mode) when swapping buffers. It had three implementations:
- In GRenderWindow, it didn't actually poll events, just set a flag and
emit a signal to indicate that a frame was displayed.
- In EmuWindow_SDL2_Hide, it did nothing.
- In EmuWindow_SDL2, it did call SDL_PollEvents, but this is wrong
because SDL_PollEvents is supposed to be called on the thread that set
up video - in this case, the main thread, which was sleeping in a
busyloop (regardless of whether sync-GPU was enabled). On macOS this
causes a crash.
To fix this:
- Rename EmuWindow::PollEvents to OnFrameDisplayed, and give it a
default implementation that does nothing.
- In EmuWindow_SDL2, do not override OnFrameDisplayed, but instead have
the main thread call SDL_WaitEvent in a loop.
Due to the way Qt performs destruction of parent/child widgets, we need
to make the lifetime of the input subsystem shared across the main
window and the render window.
Abstracts most of the input mechanisms under an InputSubsystem class
that is managed by the frontends, eliminating any static constructors
and destructors. This gets rid of global accessor functions and also
allows the frontends to have a more fine-grained control over the
lifecycle of the input subsystem.
This also makes it explicit which interfaces rely on the input subsystem
instead of making it opaque in the interface functions. All that remains
to migrate over is the factories, which can be done in a separate
change.
This commit: Implements CPU Interrupts, Replaces Cycle Timing for Host
Timing, Reworks the Kernel's Scheduler, Introduce Idle State and
Suspended State, Recreates the bootmanager, Initializes Multicore
system.
Changes the GraphicsContext to be managed by the GPU core. This
eliminates the need for the frontends to fool around with tricky
MakeCurrent/DoneCurrent calls that are dependent on the settings (such
as async gpu option).
This also refactors out the need to use QWidget::fromWindowContainer as
that caused issues with focus and input handling. Now we use a regular
QWidget and just access the native windowHandle() directly.
Another change is removing the debug tool setting in FrameMailbox.
Instead of trying to block the frontend until a new frame is ready, the
core will now take over presentation and draw directly to the window if
the renderer detects that its hooked by NSight or RenderDoc
Lastly, since it was in the way, I removed ScopeAcquireWindowContext and
replaced it with a simple subclass in GraphicsContext that achieves the
same result
Treating it as a u16 can result in a sign-conversion warning when
performing arithmetic with it, as u16 promotes to an int when aritmetic
is performed on it, not unsigned int.
This also makes the interface more uniform, as the layout interface now
operates on u32 across the board.
We can just pass a pointer to GMainWindow directly and make it a
requirement of the interface. This makes the interface a little safer,
since this would technically otherwise allow any random QWidget to be
the parent of a render window, downcasting it to GMainWindow (which is
undefined behavior).
Since C++17, the introduction of deduction guides for locking facilities
means that we no longer need to hardcode the mutex type into the locks
themselves, making it easier to switch mutex types, should it ever be
necessary in the future.
