Previously the movie was started *after* core starts running, causing potential indeterminism.
Some desyncs are still not fixed; they may be caused by core timing. More investigation is required.
Since we do not have an overlay yet, it can be confusing whether movie is being recorded or played. This makes it clear.
Status messages (e.g. system archive missing) will be overriden, but that shouldn't be too important when recording movies.
Doubled the status bar updating frequency to provide a better experience. It now updates every second.
This is completely rebuilt, in order to allow setting author, displaying movie metadata, and toggling read-only mode.
The UX is changed to more closely match other emulators' behaviour. Now you can only record/play from start/reset (In the future, we might want to introduce 'record from savestate')
Also fixed a critical bug where movie file can be corrupted when ending the recording while game is still running.
Instead of specifying it when starting playback. This is necessary as
you can end up playing the movie even if you started as Recording
(for example, loading a state in R/O mode will switch to Playing mode)
Most other emulators handle this automatically in the frontend,
booting/restarting the corresponding game instead of reporting an error.
Therefore, remove these checks and errors from the module.
These fields are included in most emulators and required by TASVideos.
`input_count` is implemented by counting the number of 'PadAndCircle' states, as this is always polled regularly and can act as a time/length indicator.
TASVideos also require the input count/frame count to be verified by the emulator before playback, which is also implemented in this commit.
The read-only mode switch affects how movies interact with savestates after you start a movie playback and load a savestate. When you are in read-only mode, the movie will resume playing from the loaded savestate. When you are in read+write mode however, your input will be recorded over the original movie ('rerecording'). If you wish to start rerecording immediately, you should switch to R+W mode, save a state and then load it.
To make this more user-friendly, I also added a unique ID to the movies, which allows each movie to have an individual set of savestate slots (plus another set for when not doing any movies). This is as recommended by staff at TASVideos.
Allocating new textures has fairly high driver overhead.
We can avoid some of this by reusing the textures from destroyed surfaces since the game will probably create more textures with the same dimensions and format.
Some games (e.g. Pilotwings Resort) create many surfaces that are invalidated quickly but were never removed.
This occasionally lead to large lag spikes due to high lookup times and other data structure management overhead.
Given this is a central class, we should flag cases where the return
value of some functions not being used is likely a bug.

I made a request on the Xbyak issue tracker to allow some constructors
to be constexpr in order to avoid static constructors from needing to
execute for some of our register constants.
This request was implemented, so this updates Xbyak so that we can make
use of it.
Previously core itself was the library containing the code to gather
common information (build info, CPU info, and OS info), however all of
this isn't core-dependent and can be moved to the common code and use
the common interfaces. We can then just call those functions from the
core instead.
This will allow replacing our CPU detection with Xbyak's which has
better detection facilities than ours. It also keeps more
architecture-dependent code in common instead of core.

UISettings::values from GMainWindow::closeEvent into its own function,

The current inconsistency can result in a developer unintentionally
creating a crash when using UNIMPLEMENTED_MSG, if they're only
familiar with UNIMPLEMENTED. The two macros shouldn't have such
wildly different behaviors.

* kernel/thread: Change owner_process to std::weak_ptr
Previously this leaked almost all kernel objects. In short, Threads own Processes which own HandleTables which own maps of Objects which include Threads.
Changing this to weak_ptr at least got the camera interfaces to destruct properly. Did not really check the other objects though, and I think there are probably more leaks.
* hle/kernel: Lock certain objects while deserializing
When deserializing other kernel objects, these objects (`MemoryRegion`s and `VMManager`s) can possibly get modified. To avoid inconsistent state caused by destructor side-effects, we may as well simply lock them until loading is fully completed.

- In `SetCurrentThreadName`, when on Linux, truncate to 15 bytes, as (at
least on glibc) `pthread_set_name_np` will otherwise return `ERANGE` and
do nothing.
- Also, add logging in case `pthread_set_name_np` returns an error
anyway. This is Linux-specific, as the Apple and BSD versions of
`pthread_set_name_np return `void`.
- Change the name for CPU threads in multi-core mode from
"yuzu:CoreCPUThread_N" (19 bytes) to "yuzu:CPUCore_N" (14 bytes) so it
fits into the Linux limit. Some other thread names are also cut off,
but I didn't bother addressing them as you can guess them from the
truncated versions. For a CPU thread, truncation means you can't see
which core it is!
The general pattern is to mark mutexes as mutable when it comes to
matters of constness, given the mutex acts as a transient member of a

These are intentionally discarded internally, since the rest of the
public API allows querying success. We want all non-internal uses of
these functions to be explicitly checked, so we can signify that we
intentionally want to discard the return values here.
The settings.h file doesn't actually need all of the definitions
on cam.h, only some of the enums. They can, therefore, be separated
into another file, which is included by settings.h instead.
The other changes are fixing files that included settings.h and
depended on indirect includes from includes of includes of cam.h
In all usages of LogSetting(), string literals are provided.
std::string_view is better suited here, as we won't churn a bunch of

While we're at it, we can fold LogSetting() into LogSettings(), given
it's only ever used there.

In cases where the size is not a known constant when inlining, AlignUp<std::size_t> currently generates two 64-bit div instructions.
This generates one div and a cmov which is significantly cheaper.
Some of the classes in this file already do this, so we can apply this
to the other ones to be consistent.
Allows these classes to play nicely and not churn copies when used with
standard containers or any other API that makes use of
std::move_if_noexcept.

We can adjust the API to allow std::size_t indices, which simplifies
operating with standard container types. It also prevents truncation
warnings from occurring in these cases as well.
* archive: Make use of std::pair for OpenFileFromArchive
The tuple only makes use of two elements, so we can use a pair to
simplify the number of underlying template instantiations that need to
be done, while also simplifying the surrounding code.
* archive: Simplify MakeResult calls
MakeResult can deduce the contained result type based off the type of
the variable being passed to it, so explicitly specifying it is a little
verbose.
* Avoid deadlock when stopping video dumping
* Use static_cast, make quit atomic

While we're at it, we can also improve some of the allocations and
copying that would be going on in one case by preallocating and then
emplacing before modifying.
This might be caused by some packet/status delay within the enet protocol, or may be caused by our not properly handling disconnection. Anyway, this situation *can* happen, and we should not crash Citra for a non-critical error.
This change is not HW tested as I do not have 3 3DSes, but this should make sure that all the members of the network hold the same `node_info`, `nodes` and the bitmasks, etc.
Previously, when connecting, the host was using the incorrect node_id to update `node_info`.
This is an attempt to fix tywald's problem with MH, reported on Discord a while ago. I'm not sure if this would actually fix that though.
I'm not sure why we decided to have a boolean here, but apparently that wasn't the correct behaviour. According to HW tests, the Software Keyboard simply displays the default text when the button text provided is empty (**not necessarily all zero**). For example, if you set a text for one of the buttons and leave others empty, the button you set will have your text, while others will have their default texts. Removed the boolean and updated frontend code to make it correct.
* gl_rasterizer_cache: Mark file-scope functions as static where applicable
Prevents -Wmissing-declaration warnings from occurring and also makes
these functions internally linked.
* gl_rasterizer_cache: Remove unused local std::string variable
Despite being unused, compilers are unable to completely remove any code
gen related to the construction and destruction of this variable, since
the destructor of std::string is non-trivial.
Thus, we can remove it to reduce a minor amount of unnecessary code
generation
* gl_rasterizer_cache: Mark hash implementation as noexcept
This shouldn't throw.
* gl_rasterizer_cache: Remove unused variable in ClearAll()
* gl_rasterizer_cache: Make use of const on references explicit
While declared as auto&, these actually behave as const auto& variables,
due to the constness of the container being iterated. We can make this
explicit for readability sake.

The size is forwarded to a std::memset call, which takes a std::size_t

It's undefined behavior to pass a null pointer to std::fread and
std::fwrite, even if the length passed in is zero, so we must perform
the precondition checking ourselves.
A common case where this can occur is when passing in the data of an
empty std::vector and size, as an empty vector will typically have a
null internal buffer.
While we're at it, we can move the implementation out of line and add
debug checks against passing in nullptr to std::fread and std::fwrite.
Prevents the internal buffer in the std::optional from being zeroed out
unnecessarily and instead sets the validity byte only in some
implementations.
While we're at it, we can make use of std::move to eliminate unnecessary
heap reallocations from occurring.
Allows us to avoid even more string churn by allowing the AddLine
function to make use of fmt formatting so the string is formatted all at
once instead of concatenating multiple strings.
This is similar to how yuzu's decompiler works, which I've made function
the same way in the past.
Quite a few service functions are stubbed but still pop all their
arguments, which can lead to unused variable warnings.
We can mark the unused arguments with [[maybe_unused]] to silence these
warnings until a full implementation of these functions are made.
Allows implementations to allocate the object and the shared_ptr control
block in one allocation instead of needing to do two separate
allocations.
Also looks much nicer to the reader.
* swkbd: Fix a bug where clicking Cancel hangs the game
The text is validated in `Finalize`. If the validation fails, an error is returned and the applet is not actually finalized. This can result in hangs.
This is usually not a problem as the frontend is expected to validate the text passed to `Finalize`. However, when the user clicked on `Cancel`, the text is ignored and the frontend won't do any validation. Therefore, we should skip the validation here as well.
Also fixed a potential data race. All these functions should now be called on the same thread
* Address review comments
Renamed the fields
Remove close button
This class is memcpy-ed and memcpy has the requirement that data passed
to it must be trivially copyable, otherwise the behavior is undefined.
This is trivial to resolve as BitField was made trivially copyable a
while ago, so this explicit copy assignment operator isn't necessary.
This can be removed as it's not used. Even if it were however, it would
be an incorrect forward declaration, as ServiceManager exists within the
Service::SM namespace, not the top-level SM namespace.
Same behavior, no heap allocation.
strings returned from glGetString() are guaranteed to be static strings,
so this is safe to do. They're also guaranteed to be null-terminated.
Some implementations can use the std::nullopt_t constructor of
std::optional to avoid needing to completely zero out the internal
buffer of the optional and instead only set the validity byte within it.
e.g. Consider the following function:
std::optional<std::vector<ShaderDiskCacheRaw>> fn() {
return {};
}
With libc++ this will result in the following code generation on x86-64:
Fn():
mov rax, rdi
vxorps xmm0, xmm0, xmm0
vmovups ymmword ptr [rdi], ymm0
vzeroupper
ret
With libstdc++, we also get the similar equivalent:
Fn():
vpxor xmm0, xmm0, xmm0
mov rax, rdi
vmovdqu XMMWORD PTR [rdi], xmm0
vmovdqu XMMWORD PTR [rdi+16], xmm0
ret
If we change this function to return std::nullopt instead, then this
simplifies both the code gen from libc++ and libstdc++ down to:
Fn():
mov BYTE PTR [rdi+24], 0
mov rax, rdi
ret
Given how little of a change is necessary to result in better code
generation, this is essentially a "free" very minor optimization.
Previously, we were returning a value that was way too big, causing an integer overflow in Fractured Souls.
According to wwylele, the biggest oberserved save size for 3DS is 1MB, so this new value should leave plenty of room, even if games use a bigger size.
Many of these functions are capable of being used within const contexts,
so we can apply the const qualifier in some cases and add const based
overloads for others, which makes the interface a little bit more
flexible and const-correct.
* core/memory: Amend unusual return value of operator=
operator= usually returns a reference to this. Given there's no comment
explaining why void was used, this can be assumed to be an oversight.

Same behavior, minus the need for an atomic reference count increment
and decrement (since MemoryRef contains a std::shared_ptr).

* am/am: Avoid redundant copy in GetProgramInfoFromCia()
We can just use a reference to the title metadata. Avoids copying
several data entries and std::vector instances that don't need to be
copied.
* hle/service: Avoid redundant copying of std::string
GetUserPath() returns the path as a reference, so we can make use of
said reference to avoid making copies.
By using a reference here, we avoid copying every single element in the
map, each of which contains a std::share_ptr and std::deque containing
std::vectors.
Same behavior, but doesn't result in an allocating copy of the passed in
string. Particularly given the string is only compared against other
existing strings.
Several standard constructors generally check if objects can be moved in
a non-throwing manner (usually via std::move_if_noexcept) to preserve
its exception guarantees. This means that if these were used with
certain containers any reallocations internally would cause resource
churn, as copies would be necessary instead of moves.
This way, if they're every used in that manner, the right behavior is
always performed.
Avoids copying the std::function when we don't need to. Particularly
given the std::function isn't actually stored anywhere, so there's no
need to move it.
Allows interfaces to move the vector into the calls, avoiding any
reallocations.
Many existing call sites already std::move into the parameter, expecting
a move to occur. Only a few remain where this wasn't already
being done, which we can convert over.
This one is similar to the ReceiveCaptureBufferInfo function except it doesn't clear the capture buffer, according to 3dbrew.
This function is used by the Home Menu
The Home Menu uses this to determine whether it is allowed to launch an app (call StartApplication)
This is a no-op for us, we allow any and all titles to be launched. The official APT module holds a list of some forbidden titles like some versions of IronFall and Flipnote Studio 3D.
On Windows, network shares use paths like \\server\share\file which were
being broken by FileUtil::SanitizePath() removing double slashes.
Changed the code in SanitizePath to permit a double-backslash if it
occurs at the start of a filepath (on Windows only).
They are called by the Home Menu during initialization.
These functions will not see much use until we actually implement application jumping and system rebooting. For now we just need them to prevent some unmapped reads in the Home Menu due to the static buffers not being properly set up.
Also rewritten how GetArchiveResource works so that they all use the same interface.
We should decide what to do with these at some point.
Related to #3131 and #3110
* Kernel/Process: Notify the CPUs that a new pagetable has been set every time the process they're executing changes.
Previously the page table would only be changed when the current CPU's page table was changed, this lead to stale JIT states and the PC going to 0 when context-switching a different core inside the ThreadManager::SwitchContext function because the JIT for a new pagetable is only constructed upon receiving the change notification.
* Kernel/Process: Use the relevant CPU's last process to determine when to switch its current process.
Previously it was checking the kernel's current_process variable, which gets overwritten every time a CPU runs its slice. The rescheduling happens after all CPUs have run their slice so the code was effectively only checking the last CPU's process.

If no matching surface can be found, ValidateSurface checks for a surface in the cache which is reinterpretable to the requested format.
If that fails, the cache is checked for any surface with a matching bit-width. If one is found, the region is flushed.
If not, the region is checked against dirty_regions to see if it was created entirely on the GPU.
If not, then the surface is flushed.

* video_core/renderer_opengl: Move SurfaceParams into its own file
Some of its enums are needed outside of the rasterizer cache
and trying to use it caused circular dependencies.
* video_core/renderer_opengl: Overhaul the texture filter framework
This should make it less intrusive.
Now texture filtering doesn't have any mutable global state.
The texture filters now always upscale to the internal rendering resolution.
This simplifies the logic in UploadGLTexture and it simply takes the role of BlitTextures at the end of the function.
This also prevent extra blitting required when uploading to a framebuffer surface with a mismatched size.

* HLE Audio: Increase frame position by input buffer sample rate
Currently the frame position moves ahead by the number of samples
output, but thats a fixed number based on the 3ds native sample rate.
Instead, based on a homebrew by cyuubi and looking at the lle audio,
this sample position should be moved forward by the number of samples
from the input buffer that was read, based on the buffer's sample rate.
* vm_manager: Handle multiple areas in ChangeMemoryState
It is possible that a few areas have the same permisson and state, but with different backing pointers. Currently, this function assumes that only one continous area is found, but this is not always the case.
* service/ldr_ro: Handle multiple areas in VerifyBufferState
It is possible that the buffer passed from the game is made up of multiple areas with the same permisson and state but different backing pointers. Change the check to allow that.
* IOFile: Make the move constructor and move assignment operator noexcept
Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.
This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.
As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.

When dumping was stopped, the game will be paused and then resumed. However when the game was already paused this will result in the game being unexpectedly resumed, which isn't what we want.

The main problem is the loss of compatibility with some controllers, but there are also
unwanted changes to the behaviour of PS4 controllers (hardcoded lightbar color).
The file's size is stored in FileSessionSlot and retrieved when the game calls GetSize. However, it is not updated when the file is written to, which can possibly change the file size. Therefore, this can cause GetSize to return incorrect results.
According to HW tests, this vsync event is signaled for activated cameras at about the same frequency as the frame rate. The last 5 vsync timings are recorded (in microseconds) and can be retrieved with the service function.
Also, corrected the default frame_rate to 15, according to HW test.
This should fix the missing camera images in certain games.
The default is discrete_interval which has dynamic open-ness.
We only use right_open intervals anyway. In theory this could allow some compile-time optimizations.
You can now directly place ExeFS overrides/patches inside the mod folder (instead of the exefs subfolder). This allows us to have drop-in compatibility with Luma3DS mods.
This is the main dialog of video dumping. This dialog allows the user to set output format, output path, video/audio encoder and video/audio bitrate.
When a format is selected, the list of video and audio encoders are updated. Only encoders of codecs that can be contained in the format is shown.
This dialog allows changing the value and unsetting one option. There are three possible variants of this dialog:
1. The LineEdit layout. This is used for normal options like string and duration, and just features a textbox for the user to type in whatever they want to set.
2. The ComboBox layout. This is used when there are named constants for an option, or when the option accepts an enum value like sample_format or pixel_format. A description will be displayed for the currently selected named constant. The user can also select 'custom' and type in their own value.
3. The CheckBox-es layout. This is used for flags options. A checkbox will be displayed for each named constant and the user can tick the flags they want to set.
These two functions allow the frontend to get a list of encoders/formats and their specific options.
Retrieving the options is harder than it sounds due to FFmpeg's strange AVClass and AVOption system. For example, for integer and flags options, 'named constants' can be set. They are of type `AV_OPT_TYPE_CONST` and are categoried according to the `unit` field. An option can recognize all constants of the same `unit`.
Previously, we just used the native sample rate for encoding. However, some encoders like libmp3lame doesn't support it. Therefore, we now use a supported sample rate (preferring the native one if possible).
FFmpeg requires audio data to be sent in a sequence of frames, each containing the same specific number of samples. Previously, we buffered input samples in FFmpegBackend. However, as the source and destination sample rates can now be different, we should buffer resampled data instead. swresample have an internal input buffer, so we now just forward all data to it and 'gradually' receive resampled data, at most one frame_size at a time. When there is not enough resampled data to form a frame, we will record the current offset and request for less data on the next call.
Additionally, this commit also fixes a flaw. When an encoder supports variable frame sizes, its frame size is reported to be 0, which breaks our buffering system. Now we treat variable frame size encoders as having a frame size of 160 (the size of a HLE audio frame).
We previously assumed that the first preferred sample format is planar, but that may not be true for all codecs. Instead we should find a supported sample format that is planar.
While YUV420P is widely used, not all encoders accept it (e.g. Intel QSV only accepts NV12). We should use the codec's preferred pixel format instead as we need to rescale the frame anyway.
This uses the mailbox model to move pixel downloading to its own thread, eliminating Nvidia's warnings and (possibly) making use of GPU copy engine.
To achieve this, we created a new mailbox type that is different from the presentation mailbox in that it never discards a rendered frame.
Also, I tweaked the projection matrix thing so that it can just draw the frame upside down instead of having the CPU flip it.

This slider affects the number of cycles that the guest cpu emulation
reports that have passed since the last time slice. This option scales
the result returned by a percentage that the user selects. In some games
underclocking the CPU can give a major speedup. Exposing this as an
option will give users something to toy with for performance, while also
potentially enhancing games that experience lag on the real console

10 slots are offered along with 'Save to Oldest Slot' and 'Load from Newest Slot'.
The savestate format is similar to the movie file format. It is called CST (Citra SavesTate), and is basically a 0x100 byte header (consisting of magic, revision, creation time and title ID) followed by Zstd compressed raw savestate data.
The savestate files are saved to the `states` folder in Citra's user folder. The files are named like `<Title ID>.<Slot ID>.cst`.

std::function is allowed to heap allocate if the size of the captures
associated with each lambda exceed a certain threshold. This prevents
potentially unnecessary reallocations from occurring.
This holds the archives which include the SelfNCCH archive which holds the RomFS files. If we don't reset it the LayeredFS class can't get destructed and mods files won't be released.
The original path (file_name.exefsdir) is still supported, but alternatively users can choose to put exefs patches in the same place as LayeredFS files (`load/mods/<Title ID>/exefs`).
Only enabled for NCCHs that do not have an override romfs.
LayeredFS files should be put in the `load` directory in User Directory. The directory structure is similar to yuzu's but currently does not allow named mods yet. Replacement files should be put in `load/mods/<Title ID>/romfs` while patches/stubs should be put in `load/mods/<Title ID>/romfs_ext`.
This implementation is different from Luma3DS's which directly hooks the SDK functions. Instead, we read the RomFS's metadata and figure out the directory and file structure. Then, relocations (i.e. replacements/deletions/patches) are applied. Afterwards, we rebuild the metadata, and assign 'fake' data offsets to the files. When we want to read file data from this rebuilt RomFS, we use binary search to find the last data offset smaller or equal to the given offset and read from that file (either from the original RomFS, or from replacement files, or from buffered data with patches applied) and any later files when length is not enough.
The code that rebuilds the metadata is pretty complex and uses quite a few variables to keep track of necessary information like metadata offsets. According to my tests, it is able to build RomFS-es identical to the original (but without trailing garbage data) when no relocations are applied.
The DIGIT filter was incorrectly implemented as preventing all digits. It actually limits the maximum digit count to max_digits, according to ctrulib and hardware testing.

Until we get a on screen display or async shader loading, we should at
least have some measure of progress in the meantime. This is 90% a port
from the loading screen I made for yuzu, but with a slightly different
changed detection for when to display the ETA. Now we keep track of a
rolling estimate for shader load ETA and only display a ETA if its going
to take longer than 10 seconds.
This is based on what was done using additional layouts, but modified
to have a variable to control rotation and making it so Single Screen
Layout behaves like Upright Single would, and Default Layout behaves
like Upright Double would, when the new variable is used.
Large Layout and Side Layout currently ignore the new variable.
New variable still currently doesn't have a hotkey.
The BPS format allows distributing patches that are smaller and that do
not contain copyrighted content if data is relocated
(unlike non-trivial IPS patches).
This is essential for games such as MM3D that have three barely
different code revisions. Supporting all three versions would
demand an unreasonable amount of work; with BPS patches only one
version has to be supported.
This changes ApplyCodePatch to return a ResultStatus, which makes it
possible to determine whether patch applying has failed. Previously,
only a boolean was returned, and false was returned when no patch
was found OR when a patch was found but applying it failed.
This also changes AppLoader_NCCH to return an error if patching fails
because the executable is likely to be left in an inconsistent state
and we should not proceed booting in that case.
This significantly reduces unnecessary disk writes and space usage
when building Citra.
libcore.a is now only ~1MB rather than several hundred megabytes.
Previously we would first attempt to use any buffer that was free,
meaning whichever buffer has already been displayed. This has poor
interactions when the operating system throttles the update rate of the
window, so if there isn't any free buffers available, just reuse the
oldest frame instead.
Simple cut/paste issue where initialized is only set to true when the
emulation attempts to init the Binary Pipe, but we used it to test if
the FFMPEG decoder was valid and disabled it if it wasn't. Just return
the value of have_ffmpeg_dl instead so when dynamic loading is added
it'll still work.
HACK
In Luigi's Mansion Dark Moon in HLE audio, the game mysteriously passes
in an extremely large value for length, which without any checks, causes
HLE audio to allocate an extremely large buffer.
This value seemingly is caused by some other HLE audio feature is missing,
and Luigi's Mansion subtracts two values to get a length, without
checking for overflow first. This appears to be caused by an incorrect
HLE audio emulation, as its fixed entirely by only changing to LLE. As
such, further investigation is required, but in the meantime, completely
eating up our users RAM is unacceptable.
The text shared memory wasn't supposed to be cleared according to my comparison with the LLE swkbd. This can cause issues in certain games such as Harvest Moon.
A null terminator is added to the text copied to mark the end of the string.
Fixes an issue where the touch point is incorrect in OpenGLWindow when the render
target is initialized for the first time with single window mode disabled.
While QOpenGLWidget sounds like a good idea, it has issues which are
harder to debug due to how Qt manages the context behind the scenes. We
could probably work around any of these issues over time, but its
probably easier to do it ourselves with a QWindow directly.
Plus using QWindow + createWindowContainer is the easiest to use
configuration for Qt + Vulkan so this is probably much better in the
long run.
Over time our config values have grown quite numerous in size.
Unfortunately it also makes the single functions we have for loading and
saving values more error prone.
For example, we were loading the core settings twice when they only
should have been loaded once. In another section, a variable was
shadowing another variable used to load settings from a completely
different section.
Finally, in one other case, there was an extraneous endGroup() call used
that didn't need to be done. This was essentially dead code and also a
bug waiting to happen.
This separates the section loading code into its own separate functions.
This keeps variables only visible to the code that actually needs it,
and makes it much easier to visually see the end of each individual
configuration group. It also makes it much easier to visually catch bugs
during code review.
While we're at it, this also uses QStringLiteral instead of raw string
literals, which both avoids constructing a lot of QString instances, but
also makes it much easier to disable implicit ASCII to QString and
vice-versa in the future via setting QT_NO_CAST_FROM_ASCII and
QT_NO_CAST_TO_ASCII as compilation flags.
We relies on UNREACHABLE's noreturn attribute to eliminate parent's "no return value" warning. However, this was wrapped in a `if(!false)` block, which compilers may not unfold to recognize the noreturn nature.
By default, DisplayRole is used as the SortRole.
This behaviour is what's expected by the user.
Made it so that an access to SortRole is equivalent to one to DisplayRole.
Also fixes a bug with directory sorting.
Also fix a small issue with incorrect shutdown ordering in SDL.
Previously the system would still be running so the telemetry task
didn't launch and detached_tasks would assert(count == 0)
Fixes a regression from #4862, which caused the NCCH title ID checking
heuristic to be skipped whenever the exheader is replaced.
I was thinking the heuristic wouldn't be needed in that case, but it
turns out that many users still have pathological NCCHs that indicate
they are encrypted but are actually decrypted...
Now the original exheader is always read and used for the heuristic
to determine whether the NCCH is actually encrypted; only then do we
load a replacement exheader (if it exists) to avoid affecting the
heuristic.
This single line mode is aimed at restoring the intended behavior with Small or None icons. Line breaks will be replaced with commas (Region row) or spaces (Name row). One can toggle this option in UI configuration.
This option was intended for enabling optimizations when all rows are granted to have the same height. In our case this is not true, and therefore the behavior is actually undefined. Different versions of Qt handle this differently. Newer versions of Qt tend to hide contents that are too big in height, which goes against our wishes. Thus, it's probably the best to disable this option so that things don't go wrong if we ever decide to update Qt.
Some titles (mostly homebrews) do not use the region free value 0x7FFF but instead set all of the region flags, resulting in all regions displayed in game list, which is not beautiful and not what we want. This fixes it by adding an all_regions check.
Separate options are now provided for FFmpeg AAC audio decoder and FFmpeg video dumper. This allows users to configure Citra with greater freedom.
Also, previously for Linux builds, AAC decoder is accidentally enabled along with the dumper, which could potentially cause patent issues (?). This commit fixes it by only enabling video dumper.
This widget provides a simple list of recorded requests as well as a simple filter and the 'Clear' button. Requests with status 'HLE Unimplemented' or 'Error' will be marked out with the red color.
This widget handles retrival of service name. For reasons refer to a previous commit message.
Added the widget to the Debugging menu, pretty much the same as other debugging widgets.
This is for displaying the service names. This function is only used in the frontend, because Recorder which is in the Kernel cannot and should not have access to SM in the System.
Pretty much the same as LLE requests, the 'translate' part is chosen. A function is added to the context class to record requests that involves unimplemented HLE functions.
The 'translate' function is a great place to put this in IMO as it is possible to get both untranslated and translated cmdbufs. However a kernel reference has to be passed here, but it is not too hard fortunately.
This class resides in Kernel mainly because that, it's hard for kernel objects to get references to the System (and therefore to the Recorder), while much easier for KernelSystem. If this is to be moved to System the code will likely get much more complex with System (or Recorder) references passed everywhere.
This is for displaying the function name for HLE requests. Probably it is possible to do the same for LLE ones but it would require having the HLE handlers available even when not using them, which doesn't seem to make sense and is more of a hack than a proper solution in my opinion.
