Also some minor refactoring of nearby/related code:
* Make non-obvious variable types explicit instead of auto.
* Throw some consts around.
* Use setDisabled(empty) instead of setEnabled(!empty).
Changes the RetroAchievements "Log In" button's text to "To log in, stop the current emulation." when the button is disabled because an emulation session is active. This allows a user to understand why the button is disabled, and how this state can be resolved.
Previously, it could be unclear why this button was disabled without an understanding of the underlying system.

The description of the Speed Limit setting currently uses a lot of
complicated terms, like "emulated time" (known to many Dolphin
developers, but in my experience not known by even advanced emulator
users) and "maximum time scale" (I have never heard it before). The
meaning of "sustainable" is also unclear in context.
This commit rewords the description to be easier to understand.
Fixes https://bugs.dolphin-emu.org/issues/13593. Before, it would attempt to
use the old shader, which did not exist for the new stereo mode. Changing the
postprocessing shader afterwards would work properly, although passive 3D only
has one option, so it was just broken without restarting Dolphin.
This also fixes the UI not updating when using one of the stereo toggle hotkeys.
These patches were added in bde9a459cd
and enabled by default in 36ecfdd6b5.
They allowed the game to run in Dolphin but disabled dynamic shadows.
The game adds 4 to the start address of otherwise valid display lists
for no obvious reason. Now that Dolphin forces 32-byte alignment these
patches are no longer needed.
Input/output tracking is intended to speed up incremental builds by
skipping a target when it doesn't need to be built. However, this seems
to be unreliable for UnitTests' AfterBuild target. Let's remove it.
It's still the case that UnitTests' AfterBuild target will be skipped if
UnitTests doesn't need to be rebuilt. (Note that UnitTests always needs
to be rebuilt if SCMRevGen changed.)
I haven't seen these problems with DolphinQt's rather similar
input/output tracking. This may be because DolphinQt's one also has the
exe file as an input/output.
`std::bit_cast` participates in overload resolution only if `sizeof(To) == sizeof(From)` and both `To` and `From` are *TriviallyCopyable* types, so the static assertions here can be removed. `[[nodiscard]]` was added as well.
Like the previous commit, but for UnitTests. This time all operating
systems were affected.
I also made UnitTests.vcxproj use the same way of copying as
DolphinQt.vcxproj, just for consistency.
For a long time now, we've had a problem where game INIs persist in
the copied Sys folder if they've been deleted from the original Sys
folder. (I still have hundreds of game INIs locally that only set
EmulationStateId, and we removed those game INIs 6 years ago. On the
buildbot, we do occasionally clear out the build directories manually,
so I'd assume it's not quite as bad there.)
This commit fixes the problem by deleting the output Sys folder before
copying the original Sys folder to the output Sys folder. This should be
a bit slower, but in my testing, the difference seems small. At least if
you have an SSD, which I really hope people have nowadays!
Operating systems other than Windows have not been touched, because:
* Android: Already explicitly deletes the output Sys folder.
* macOS: Does some magic to put the Sys folder in the app bundle, which I
will simply assume isn't affected by this problem, without testing.
* Linux: Expects the person building to manually manage the Sys folder.
Update the checkmarked slot in the Select State Slot menu when the
Increase Selected State Slot or Decrease Selected State Slot hotkeys are
pressed.
The actual selected save slot was being changed correctly before this
commit; this just fixes the menu checkmark.
The biquad filter is used in all Pikmin games for cursor sound effects
in the main menu, although the difference is subtle.
The low-pass filter is used at least by Pikmin 2 Wii during the
spaceship crash in the intro and fixes the missing "puff" sound effects
whenever there is black smoke coming out of the engine.
With this change, a different message is displayed if starting a game with RetroAchievements fails due to the Dolphin version being blocked as opposed to failing because the game hash is unsupported.
This compile definition was removed in 68cbd2640d because it was complicated by changes in 50dc0ffbce. Thus, the LLVM disassembler would never be used in UICommon's Disassembler class.
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.
`Layer::Save` only does its thing if the layer has `is_dirty == true`.
But SYSCONF could have been modified by other layers, so if the base layer wasn't made dirty by anything else, then it wouldn't be restored.
Fixes https://bugs.dolphin-emu.org/issues/13580
I tried making the new templated Interpret callback test only the relevant exceptions (EXCEPTION_DSI, EXCEPTION_PROGRAM, or both), but didn't find a significant performance boost in it. As I am learning, the biggest bottleneck is the number of callbacks emitted, not usually the actual contents of them.
WritePC is now needed far less, only for instructions that end the block. Unfortunately, WritePC still needs to update `PowerPCState::npc` to support the false path of conditional branch instructions. Both drawbacks should be smoothed over by optimized cached instructions in the future.
Use QObject->deleteLater() instead of the delete operator to destroy
child widgets of the layout. This prevents crashes caused by pending
events trying to access the now-destroyed widget.
The player_index field in question is ultimately what gets used to determine which ranks get displayed in the leaderboards chart, and because this was missing the chart was simply displaying the top four results no matter what.
The cause of the leaderboard spam was primarily this call where if there was an attempt to get leaderboard info and there wasn't already, there would be a fetch request. This is bad for many reasons: some games have hundreds of boards that will be fetched at startup, if there's simply no data to populate that board, this will just continue to fetch every time the dialog needs to update. To mitigate this, I simply don't load leaderboard information until there are events for that leaderboard - less information for the player, sadly, but heavily cuts down on the number of leaderboard fetches.
Now that we have some test data, it wasn't showing up in the leaderboards tab; this fixes it to ensure (1) that the right ID is being passed to UpdateRow and (2) the map of leaderboard entries is being populated correctly.
Currently we're showing OSD messages for unknown patches in known INI
files, but not for unknown patches in unknown INI files. I don't think
this distinction makes much sense to the user. If there's a patch the
user can't use, they probably want to be aware of that fact.
0c14b0c8a7 made Dolphin load a file from
the Sys folder the first time AchievementManager::GetInstance() is
called. Because Android calls AchievementManager::GetInstance() from
setBackgroundExecutionAllowedNative, this had two negative consequences
on Android:
1. The first time setBackgroundExecutionAllowedNative gets called is
often before directory initialization is done. Getting the path of
the Sys folder before directory initialization is done causes a crash.
2. setBackgroundExecutionAllowedNative is called from the GUI thread,
and we don't want file I/O on the GUI thread for performance reasons.
This change makes us load the data from the Sys folder the first time
the data is needed instead. This also saves us from having to load the
data at all when hardcore mode is inactive.
We mustn't use m_system when it is nullptr. This was causing Dolphin to
crash on Android whenever an activity was recreated or resumed while
emulation is running, which is super common.
This unit test compares ApprovedInis.json with the contents of the GameSettings folder to verify that every patch marked allowed for use with RetroAchievements has a hash in ApprovedInis.json. If not, that hash is reported in the test logs so that the hash may be updated more easily.
Prototype of a system to whitelist known game patches that are allowed to be used while RetroAchievements Hardcore mode is active. ApprovedInis.txt contains known hashes for the ini files as they appear in the repo, and can be compared to the local versions of these files to ensure they have not been edited locally by the player. ApprovedInis.txt is hashed and verified similarly first, with its hash residing as a const string within AchievementManager.h, ensuring ApprovedInis and the hashes within cannot be modified without editing Dolphin's source code and recompiling completely.
The challenge popups have proven to be excessive and are no longer useful thanks to the achievements hotkey. Instead, those events will ask for an immediate RP-level update to the achievements dialog, which will among other things re-sort the dialog to show challenges on top faster.
This way, by pressing Continue on top of a breakpoint, the emulation will actually continue (like on Cached Interpreter and JIT), instead of doing nothing.
Before:
1. In theory there could be multiple, but in practice they were (manually) cleared before creating one
2. (Some of) the conditions to clear one were either to reach it, to create a new one (due to the point above), or to step. This created weird behavior: let's say you Step Over a `bl` (thus creating a temporary breakpoint on `pc+4`), and you reached a regular breakpoint inside the `bl`. The temporary one would still be there: if you resumed, the emulation would still stop there, as a sort of Step Out. But, if before resuming, you made a Step, then it wouldn't do that.
3. The breakpoint widget had no idea concept of them, and will treat them as regular breakpoints. Also, they'll be shown only when the widget is updated in some other way, leading to more confusion.
4. Because only one breakpoint could exist per address, the creation of a temporary breakpoint on a top of a regular one would delete it and inherit its properties (e.g. being log-only). This could happen, for instance, if you Stepped Over a `bl` specifically, and pc+4 had a regular breakpoint.
Now there can only be one temporary breakpoint, which is automatically cleared whenever emulation is paused. So, removing some manual clearing from 1., and removing the weird behavior of 2. As it is stored in a separate variable, it won't be seen at all depending on the function used (fixing 3., and removing some checks in other places), and it won't replace a regular breakpoint, instead simply having priority (fixing 4.).
Now it actually does what it says on the name, instead of creating a breapoint and doing nothing else (not even updating the widget).
Also, it now can't be selected if emulation isn't running.
Closes https://bugs.dolphin-emu.org/issues/13532
Change misleading names.
Fix function usage: Intepreter and Step Out will not check breakpoints in their own wrong way anymore (e.g. breaking on log-only breakpoints).
There are two pieces of functionality to be added here. One, we want to disallow pausing too frequently, as it may be used as an artificial slowdown. This is handled within the client, which can tell us if a pause is allowed. Two, we want to call rc_client_idle on a periodic basis so the connection with the server can be maintained even while the emulator is paused.
When the immediate value is zero, we can do a negation. On ARM64 the NEG
/NEGS instructions are just an alias for SUB/SUBS with a hardcoded WZR.
Before:
```
ldr w22, [x29, #0x28]
mov w21, #0x0 ; =0
subs w22, w21, w22
```
After:
```
ldr w22, [x29, #0x28]
negs w22, w22
```
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.
Whenever a request to update the Rich Presence comes in, typically every ten seconds, the Achievement Progress Widget will update the sort order of the achievements and all of their measured values.
bugfix: SetQWidgetWindowDecorations(this); not called before show() for Windows darkmode titlebars.
The actual call to (QWidget) show() needed to come sooner. Show() was originally left alone, but with other checks needing to move with (QWidget) show(), this function became less useful. Show() was originally created to fix the render widget appearing behind the main window, but that appears to work fine in this iteration.
The measured_progress C string for achievements to display potentially contains junk data after the null terminator, which was rendering in the QString in the dialog. This trims those junk characters.
This causes Dual Core to lock up during the boot sequence, because it tries to wait for a not-yet-running GPU thread.
Fixes https://bugs.dolphin-emu.org/issues/13559
rc_client calls the provided memory peeker asynchronously in the callback for starting a session, to validate/invalidate the memory used for achievements. Dolphin cannot access memory from any thread but host or CPU so this access has a small chance of being invalid. This commit adds a MemoryVerifier that the AchievementManager will use to perform this, before changing the peek method back to the original MemoryPeeker for normal operation.
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.
