Recently we have been getting some requests to make the existing vsync
setting available in the Android GUI:
https://bugs.dolphin-emu.org/issues/13650https://forums.dolphin-emu.org/Thread-vsync-toggle-for-android
I don't quite understand why enabling the vsync setting is helpful when
Android already enforces vsync, but I guess having the option available
doesn't hurt. I'm putting the setting under Advanced, unlike in
DolphinQt, since there's no clear reason why the typical user would want
to use this setting.
This reverts the revert commit bc67fc97c3,
except for the changes in BaseConfigLoader.cpp, which caused the bug
that made us revert 72cf2bdb87. PR 12917
contains an improved change to BaseConfigLoader.cpp, which can be merged
(or rejected) independently.
A few changes have also been made based on review comments.
Dolphin has been using edge-to-edge rendering for a little while now,
but it has required a bit of manual work. Now that edge-to-edge is
becoming something expected of apps in Android 15, there's a nicer API
we can use.
Tested on Android 8, 11 and 13, with no changes in behavior noted.
So far, Dolphin hasn't been able to run on Android devices that use a
16 KiB page size. 16 KiB page sizes are a very new Android feature that
no phones have shipped with so far, so we're still compatible with the
phones that exist out there, but let's get this fixed before phones
start shipping with 16 KiB page sizes.
Because I couldn't get Android Studio's emulator to work, I haven't been
able to confirm that this change actually makes Dolphin fully compatible
with devices that use a 16 KiB page size. But I have confirmed that this
doesn't break anything on a regular 4 KiB page size device.
With 12 uses of `JoinStrings` in the codebase vs 36 uses of `fmt::join`, fmtlib's range adapter for string concatenation with delimiters is clearly the preferred option.
In a race condition, the core could shut down between the `JitInterface::GetCore` nullptr check and the `JitInterface::JitBlockLogDump` call which constructs a `CPUThreadGuard`. In this scenario, nothing horrible happens—`JitBlockLogDump` also checks for a nullptr—but it would be a failure to display the correct feedback to the user.
To fix the crash in input device sensor handling, we should look up
Sensors using structural equality. Unfortunately, Sensor.equals
implements referential equality, and HashMap doesn't let us provide a
custom comparator. Because the number of sensors is relatively small,
and because we have a reason to keep a sorted list of sensors around
anyway, let's switch from HashMap to ArrayList.
This reverts commit 72cf2bdb87.
SYSCONF settings are getting cleared when they shouldn't be. Let's
revert the change until I get proper time to figure out why it's broken.
Some pieces of code are calling IsRunning because there's some
particular action that only makes sense when emulation is running, for
instance showing the state of the emulated CPU. IsRunning is appropriate
to use for this. Then there are pieces of code that are calling
IsRunning because there's some particular thing they must avoid doing
e.g. when the CPU thread is running or IOS is running. IsRunning isn't
quite appropriate for this. Such code should also be checking for the
states Starting and Stopping. Keep in mind that:
* When the state is Starting, the state can asynchronously change to
Running at any time.
* When we try to stop the core, the state gets set to Stopping before we
take any action to actually stop things.
This commit adds a new method Core::IsUninitialized, and changes all
callers of IsRunning and GetState that look to me like they should be
changed.
Core::GetState reads from four different pieces of state: s_is_stopping,
s_hardware_initialized, s_is_booting, and CPUManager::IsStepping.
I'm keeping that last one as is for now because there's code in Dolphin
that sets it directly, but we can unify the other three to make things
easier to reason about.
This commit also gets rid of s_is_started. This was previously used in
Core::IsRunningAndStarted to ensure true wouldn't be returned until the
CPU thread was started, but it wasn't used in Core::GetState, so
Core::GetState would happily return State::Running after we had
initialized the hardware but before we had initialized the CPU thread.
As far as I know, there are no callers that have any real need to know
whether the boot process is currently initializing the hardware or the
CPU thread. Perhaps once upon a time there was a desire to make the
apploader debuggable, but a long time has passed without anyone stepping
up to implement it, and the way CBoot::RunApploader is implemented makes
it rather difficult. So this commit makes all the functions in Core.cpp
consider the core to still be starting until the CPU thread is started.
Right now, we assign a versionCode to each Android build of Dolphin by
counting the total number of git commits made. This has worked fine so
far, but it won't work as-is for the new release process.
Let's say we're currently on commit 20000. If we want to create a
release under the new release process, we would create a release branch,
add a new commit on it that updates the release name in CMake files and
so on, and create a tag for that commit. The Android build of this
release commit would get the version code 20001. However, the master
branch is also going to get a commit with the version code 20001 sooner
or later, and this commit would be an entirely different commit than
commit 20001 on the release branch. This isn't much of a problem for
people downloading Dolphin from dolphin-emu.org, but it's a big problem
for Google Play, as Google Play doesn't allow us to upload two builds
with the same version code.
This commit makes us calculate the Android version code in a new way:
The number of commits times two, and if the current build isn't a
release build, plus 1. (We check whether the current build is a release
build by checking whether there's a tag for the current commit.)
With this new version code scheme, the release commit described in my
example would get the version code 40002, and the master commit would
get the version code 40003. This lets us upload both corresponding
builds to Google Play, and also lets the user switch from the release
build to the development build if they would like to. (Under normal
circumstances, Android forbids installing a build with an older version
code than the currently installed build. Therefore, whether the 1 is
added for release builds or for development builds is a decision with
consequences.)
Enable emulator hotkeys and controller input (when that option is
enabled) when a TAS Input window has focus, as if it was the render
window instead. This allows TASers to use frame advance and the like
without having to switch the focused window or disabling Hotkeys Require
Window Focus which also picks up keypresses while other apps are active.
Cursor updates are disabled when the TAS Input window has focus, as
otherwise the Wii IR widget (and anything else controlled by the mouse)
becomes unusable. The cursor continues to work normally when the render
window has focus.
