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.

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.
When AchievementProgress::UpdateData(false) is called, it will now empty itself and reinsert all existing boxes, re-sorted into their current buckets, and call UpdateProgress on them all.
Rerendering the entire Achievements dialog every EmulationStateChanged signal is far too often when it turns out that signal fires multiple times to confirm game close, for example. This change results in only the settings changing on EmulationStateChanged, and having the Hardcore mode toggle (which DOES require redrawing the entire dialog) emit its own signal alongside EmulationStateChanged.
