Allow loading a custom font by naming it OSD_Font.ttf and placing the file in the User/Load folder, to load that font instead. Useful for future testing.
Don't log a warning in GetPropertyHelper when the property isn't
present. The function returns an optional, so any callers that want to
log a warning when nullopt is returned can do so themselves.
This prevents plugged-in devices (an Xbox One controller in my case)
from spamming the message "W[COMMON]: CM_Get_DevNode_Property returned:
37" twice per second (that value being CR_NO_SUCH_VALUE).
Added some new visibility toggles so players can choose what to show (or hide) during their RetroAchievements runs:
Toggle for the Speedrun Leaderboards timer
Toggle for Achievement Challenge badges
Check if the return value of std::filesystem::remove_all is -1 rather
than 0; the former is the specified return value if there's an error
while 0 just means the directory already didn't exist (which is the end
result we want).
Previously error messages such as the following were possible:
E[COMMON]: DeleteDirRecursively: [path]/User/RedirectSession/ failed The
operation completed successfully.
Also adds a period in the error string to make it look nicer.
Rename m_session to m_last_value_session to better reflect its meaning
and distinguish it from m_current_value_session which will be introduced
in another commit.
macOS does not support `SO_PRIORITY` on sockets, but it does apparently
support configuring sockets with a priority flag via a parameter called
`SO_NET_SERVICE_TYPE`. It doesn't appear to be especially well
documented, but it seems to exist as far back as 10.11 (El Capitan).
This patch sets QoSSession to treat connections as
"responsive multimedia audio/video", which some docs appear to describe
as "low delay tolerant, low-medium, loss tolerant, elastic flow,
variable packet interval, rate and size".
Preserve the configured logging verbosity unless the user actually
changes it, rather than capping it to LINFO on release builds.
Rename LogManager::m_level to m_effective_level and distinguish between
the config and effective level in various function/variable names.
Make m_effective_level atomic to prevent data races when setting the
effective log level from the config changed callback.
USBDevicePicker: Modify USBDeviceAddToWhitelistDialog to be more generic, and use it for a new "More Options..." selection in Bluetooth Passthrough adapters
The `QtUtils::AdjustSizeWithinScreen()` function now centers the
widget on their parent window after the widget's size is adjusted. This
is required in some desktop environments (generally on Linux systems) to
ensure that the just-resized widget remains aligned with its parent
window.
The creation of the **Cheats Manager** dialog is now deferred to first
show, as creating it within the main window's constructor prevents the
dialog from knowing the real position of its parent window, which is
only properly calculated on first show.
For the same reasons, the analytics prompt is now shown only when the
application is ready (i.e. when the main window has been shown).

Avoid creating and then destroying a leaderboard list when game is null,
as doing so causes an access to uninitialized memory due to a bug in
rcheevos.
This can be triggered by starting a game with an invalid or expired
login token.
Without cache emulation, these instructions are functionally identical.
In the interpreter, their only difference is related to HID registers checks, which the JIT already doesn't do for `dcbz`.
A loop with `dcbz_l` is used in the SDK function `LCEnable`, which is called frequently in some games.
When opening a file dialog to set the location of a custom path, use the
corresponding user path as the starting location instead of the current
custom path.
When no custom path was set the dialog would be opened with a blank path
which causes Windows (not sure about other platforms) to open the dialog
at the same location where the last dialog was closed, or at the current
working directory if no previous dialog had been opened.
If a nonempty custom path has been set then it has also set the
corresponding user path, so the behavior in that case is unchanged.
Adds `DocumentsContract.Root.FLAG_SUPPORTS_IS_CHILD` to the list of the flags in order to show up for third-party apps for easier file syncing with local/cloud file server providers
Adds `DocumentsContract.Root.FLAG_LOCAL_ONLY` to the list of the flags in order to show up for third-party apps for easier file syncing with local/cloud file server providers
The callback mechanism AchievementManager had until now only supported
one caller registering a callback, and it didn't have any
synchronization. This isn't a problem for DolphinQt, but the PR to add
Android support for RetroAchievements exposes these problems. Let's
replace it with HookableEvent, which can handle all of this.
The instruction implementations that were shifting the size by 4 would
emit an incorrect instruction when given a size of 64. The correct
implementation is to count the number of leading or trailing zeroes in
the size parameter, which is what IntLog2 does.
No callers are affected by this, as they all use sizes other than 64.
Actually, some of these instructions are even invalid with a size of 64,
but I'm changing them anyway for consistency with the others.
When dragging the selection, the mismatch between signal
(itemSelectionChanged) and data consumed (currentRow) seemed to cause
the description to lag behind by one row.
We should attempt to use not only mirrored versions of the immediate as
an ORR base, but also the immediate itself. This lets us emit certain
64-bit constants using fewer instructions.
Improves the accuracy of FMADDS and other single precision FMA operations
This is accomplished by using an error-free transformation
It also thoroughly explains the quirks and difficulty of these operations
This fixes Mario Strikers and is necessary for fully fixing 1080 Avalanche
For single precision inputs it should be equivalent to a 32-bit FMA
Aside from allowing users to persistently set the window to their
desired size, this is also necessary to allow saving of the splitter
positions in FIFOAnalyzer to work correctly.
Make MainWindow::m_fifo_window a unique_ptr to ensure its destructor is
triggered when MainWindow is destroyed.
FIFOPlayerWindow doesn't set MainWindow as its parent in order to
prevent raising MainWindow when focusing FIFOPlayerWindow. This avoids
MainWindow covering up RenderWidget when, e.g., trying to use the object
range feature to pinpoint the index of a particular object.
As a consequence, unlike most QObjects FIFOPlayerWindow wasn't destroyed
when its parent widget was since it didn't have one.
IsolateWasOverwritten and IsolateNotOverwritten share the same basic
logic and have almost exactly the same code, with the only difference
being the comparison function used to keep or discard branches. To avoid
unnecessary code duplication and ensure that the functions stay in sync
after any future changes, create a helper function that takes the
comparison function as a parameter and have IsolateWasOverwritten and
IsolateNotOverwritten call that helper.
Show "(off)" instead of "" when the default post-processing effect is
selected. This also indirectly fixes issues with keyboard navigation of
the post-processing effect combobox when the default is selected,
resolving https://bugs.dolphin-emu.org/issues/13863.
m_post_processing_effect was previously using the ConfigStringChoice
constructor that assumes the text and data of each option are identical.
This is true for all the other effects, but since "(off)" has the config
value of "" this assumption was failing for it, causing the combobox to
be blank.
Previous changes to the patch allowlist format were not reflected in AchievementManager; this corrects that and re-enables patches and codes in hardcore mode.
Equivalent to a negation, no need to materialize the zero.

In certain cases, the platform can be "wayland-egl", "wayland-xcomposite", and other values for which I haven't found a full list yet. Instead of matching only "wayland", we now look for "wayland" anywhere in the `QT_QPA_PLATFORM` string in a case-insensitive manner.

`CaseInsensitiveContains`' implementation was heavily inspired by GNU's non-standard glibc `strcasestr` function, which can be found here licensed under GPLv2 or later: https://ftp.gnu.org/gnu/libc/
Host_RequestFullscreen and Host_UpdateMainFrame have been removed, and
Host_RequestRenderWindowSize has been used by DolphinQt since 80699096
and by Android since e8739156.
Remove Host_RefreshDSPDebuggerWindow (which hasn't done anything since
DolphinWX was removed in 44b22c90) and DSP::Host::UpdateDebugger (which
only called Host_RefreshDSPDebuggerWindow).
Remove Host_UpdateMainFrame(). The only non-empty call happened in
DolphinNoGUI which called s_update_main_frame_event.Set(), but
DolphinNoGUI never waits on that event.
Compared to the former, the latter invalidates the icache, which is
something that is likely desired for patches (especially if they are
applied while the game is running).
Invalidate icache only if target address has a different value. Take separate arguements,
instead of a struct, to allow easier usage elsewhere. Overload with u8,
u16 and u32 values for the same reason.
Keep the BalloonTip open when the BalloonTip's arrow prevents the cursor
from being inside the spawning ToolTipWidget, which triggers the
ToolTipWidget's leaveEvent and would previously close the BalloonTip.
When that happens track the cursor until it either leaves the
ToolTipWidget's bounding box or leaves the BalloonTip and goes back to
the ToolTipWidget, and respectively close the BalloonTip or leave it
open.
When 9d9b6d8 changed our target SDK version to Android 16, it made
Android 16 stop calling onBackPressed and stop delivering KEYCODE_BACK
events. Dolphin's code isn't ready for that yet.
Android lets us opt out of this new behavior for now, so let's do so.
But the opt-out will presumably stop working once we start targeting
Android 17, so we're going to have to update Dolphin's code within the
next one or two years to support the replacement API.
Number of instructions stays the same, but we remove the false
dependency on the input registers.

Dual Core is primarily known as one of the first troubleshooting steps when emulation or NetPlay misbehave.
I believe(?) the original intent with having it on by default was likely to support users with weaker machines. However, I believe it would be a lot more reasonable for users to manually enable dual core if they really need the performance boost, rather than it is for them to have come ask us in support channel why their cleanly-installed Dolphin is not emulating their games properly.
Instead, this creates a fragile first impression where a clean install of Dolphin is already set up in a way that leads to inexplicable crashes, subtle timing bugs, and NetPlay desyncs.
Note: This changes only applies to the Desktop application, since mobile devices *do* really need the performance boost.
For thread safety, we shouldn't return any pointers or references that
can be used to mutate the state of the PPCSymbolDB. This should be the
final part of making PPCSymbolDB thread safe unless I've missed
something.
9395238 added locking in some PPCSymbolDB functions that access member
variables, but far from all. To ensure thread safety, this commit adds
the missing locking.
9395238 added a mutex to PPCSymbolDB, and made functions return with an
"empty" result if called while the mutex is locked. This new behavior
has the potential to affect not only less important call sites like the
symbol printing mentioned in a comment, but also the JIT deciding if it
should HLE a function.
A later commit in this pull request decreases the amount of lock
contention, reducing the performance impact of this commit.
This lets us get rid of the Reset call in ProcessInputPayload, which was
causing us some threading headaches (see 74ed5e5532). Instead we handle
disconnection in the same way as the libusb implementation does.
We can register a BroadcastReceiver to have Android tell us when a GC
adapter gets connected instead of having a loop where we continuously
call SleepCurrentThread(1000) and poll the current status. When waiting
for a GC adapter to connect, this both reduces power usage and improves
responsiveness.
Note that I made openAdapter get the UsbDevice that's been stored by the
hotplug code instead of having openAdapter find the UsbDevice on its own
like before. This is only because I want to ensure that the UsbDevice
being tracked for disconnection is the same as the UsbDevice actually
being used, in case the user has multiple adapters connected.
Aims to fix https://bugs.dolphin-emu.org/issues/13686.
I'm using a less efficient approach for Jit64 than for JitArm64. In
JitArm64, I'm flushing in the slow access code, but in Jit64, I'm
flushing before the split between the slow access code and the fast
access code, because Jit64 doesn't keep register mappings around for
when it's time to emit the slow access code. But the flushing code is
only emitted when there are memory breakpoints with conditions, so I'd
say that this is a performance loss we can live with.
The next commit will add another piece of code that depends on this
assumption that we've been making. Good opportunity to document it.
In practice, all callers of EmitBackpatchRoutine are locking X30.
When Android sends Dolphin to the background, emulation *must* pause,
otherwise emulation continues running and continues outputting audio to
the user. RetroAchievements mustn't be allowed to override it.
The SetDisc function calls AchievementManager::LoadGame with the game's
volume. Calling AchievementManager::LoadGame again afterwards with
nullptr prevents RetroAchievements from working.
Use ToolTipWidget::SetDescription insead of QWidget::setTooltip to put
the description in the BalloonTip with the title, instead of having the
description be in a separate standard tooltip.
It is useful enough for the Code widget to be enabled the first time
debugging is enabled, but it should not be re-enabled every time the
setting is toggled off and then back on. This also ensures that the
interface is consistent if debugging is enabled without using the
checkbox.
Dolphin never emulated the AHBPROT register before, but the default
value when reading from unimplemented MMIO registers used to be -1,
which happened to match what AHBPROT reads as when all restrictions are
disabled. In 6f25e20c6a I changed the
default to 0 to match observed hardware behavior in the memory range of
the command processor. This broke libogc's DI_Init() which checks
AHBPROT for full hardware access (presumably to ensure that bypassing
IPC for Video DVDs will work).
Fix a copy-paste error causing MemoryWidget's splitter to load the wrong
state data when creating the MemoryWidget.
For me this caused the side panel to be scrunched up every time I
started Dolphin, but the exact effects probably depend on the state of
your MemoryWidget and CodeWidget.
Fix two bugs that occurred when viewing a memory range starting shortly
before 0xffffffff.
Bug 1: When there was at least one visible memory address at or after
0x0 none of the values would be displayed even when some of the
addresses were valid. This happened because the loop condition in
GetValues immediately returned false since m_address_range.first >
m_address_range.second, causing m_values to be empty. This in turn led
every address to be considered INVALID_MEMORY in UpdateColumns.
Bug 2: When m_address_range.second was equal to 0xffffffff GetValues
would enter an infinite loop. This happened because address would
overflow to 0 after printing the last value in the table, causing the
loop condition address <= m_address_range.second to be true forever.
Require ReadArray and WriteArray to be called with a trivially copyable
type.
ReadArray and WriteArray call std::fread and std::fwrite respectively.
These functions trigger undefined behavior when the objects are not
trivially copyable, so this adds that requirement to the callers.
Fix creation of a ".sav" file in the current working directory on
emulation shutdown when a slot is set to "Advance Game Port" and the
"GBA Cartridge Path" is empty.
Fixes https://bugs.dolphin-emu.org/issues/12975.
Fix some common anti-patterns with these data structures.
- You can dereference the iterator returned by `find` to access the
underlying value directly, without an extra `operator[]`/`at`.
- Rather than checking for an element before insertion/deletion, you can
just do the operation and if needed check the return value to
determine if the insertion/deletion succeeded.
Unlike custom banners which work as an override, this mechanism works as
a fallback. The use case is if you have games you don't really play but
want to keep around for testing purposes without filling up your NAND
with lots of saves. For ease of use, the directory structure is the same
but only title/$title_hi/$title_lo/data/banner.bin files are
relevant.
Fix the input string failing to validate when the "Hex Byte
String" input type is selected and either the user adds a 0x prefix or
the "Hex" box is checked (or both).
The latter failure was particularly troublesome because when "Hex Byte
String" is selected the "Hex" checkbox is disabled. Users would have to
switch to a data type that enabled the box, toggle it, then switch back
to "Hex Byte String" to fix it.
Fix these errors by not adding a prefix when the "Hex" box is checked,
and removing the "0x" prefix from the user's input if present.
Fix validation failing when the user has checked the Hex box and also
includes a "0x" or "-0x" prefix in their input.
Previously an extra "0x" would be inserted, causing the user's input of
"0x13" to become "0x0x13" which would then fail to validate.
Separate LibUSB logic into LibUSBBluetoothAdapter class.
Submit transfers on thread with proper timing.
Throttle before ACL input for reduced input latency.
Immediately send IPC replies for outgoing data.
Continuously submit libusb transfers to fill HCI/ACL input queues.
Simplify endpoint handling and state saving.
Other cleanups.
Remove the redundant s_populate_mutex and only use
ControllerInterface::m_devices_population_mutex instead to prevent a
deadlock caused by locking them in opposite orders.
The device population functions in the win32 InputBackend previously
locked s_populate_mutex first before calling various functions that
locked m_devices_population_mutex. This normally worked but
ControllerInterface::RefreshDevices locks m_devices_population_mutex
first and then calls HandleWindowChange which then locked
s_populate_mutex, potentially causing the deadlock.
Fix this by using PlatformPopulateDevices to lock
m_devices_population_mutex before running the code that was previously
protected by s_populate_mutex. The functions in question lock
m_devices_population_mutex anyway, so this shouldn't meaningfully
increase contention on the lock.
Reproduction steps:
* Let Dolphin finish startup.
* In Win32.cpp::OnDevicesChanged set a breakpoint on the call to
PlatformPopulateDevices. When the breakpoint is triggered the function
will have locked s_populate_mutex, but since PlatformPopulateDevices
won't have run yet m_devices_population_mutex will still be unlocked.
* Unplug a device from your computer.
* Wait for the breakpoint to trigger. (At this point you can plug the
device back in).
* Freeze the ntdll.dll!TppWorkerThread() that triggered the breakpoint.
* Resume Dolphin and start a game.
* Core::EmuThread will call ControllerInterface::ChangeWindow which
calls RefreshDevices. It locks m_devices_population_mutex, then calls
InputBackend::HandleWindowChange, which tries to lock
s_populate_mutex.
* Unfreeze ntdll.dll!TppWorkerThread().
At this point EmuThread and TppWorkerThread are deadlocked. The UI is
still responsive since the Host thread is unaffected, but trying to stop
the game or close Dolphin normally will fail since EmuThread is unable
to stop.
