xbyak is intended to be installed in /usr/local/include/xbyak.

previous changes had forced every single user to use custom
directories for NAND and SDMC. Those paths were saved to the
config file and would interact badly with portable builds.
Games will sometimes use these when representing open right bounds
and so disallowing it caused regressions, with a notable example
being when MemoryFill is called to the end of vram, causing an
"invalid end address" error.
This had been noted on a comment in GetPhysicalRef prior to the
regression.

* AMDs new driver fixed many issues in the OpenGL driver. No reason to
keep these hacks. In addition the upgrade to 4.3 guarantees the
existance of required extensions, so no need to check for them
* The current backend heavily depends on many extensions for shadow
rendering and texture cubes in the fragment shaders. All these
extensions were incorporated to core in 4.3. Support is practically
ubiquitous and requiring support for it makes things a lot easier
* This commit aims to both continue the rasterizer cache cleanup by
separating CachedSurface into a dedicated header and to start weeding
out the raw OpenGL code from the cache.
* The latter is achieved by abstracting most texture operations in a new
class called TextureRuntime. This has many benefits such as making it easier
to port the functionality to other graphics APIs and the removal of the need
to pass (read/draw) framebuffer handles everywhere. The filterer and
reinterpreter get their own sets of FBOs due to this, something that
might be a performance win since it reduces the state switching
overhead on the runtime FBOs.
The JNI functions that have "UTF" their name use "modified UTF-8"
rather than the standard UTF-8 that Citra uses, at least according
to Oracle's documentation, so it is incorrect for us to use them.
This change fixes the problem by converting between UTF-8 and
UTF-16 manually instead of letting JNI do it for us.
Resolves#6077
If only `SDL_INIT_JOYSTICK` is used, `InputCommon::SDL::SDLState` later tries to initialize the game controller in a background thread, which on macOS causes a crash in `SDL_PumpEvents`. From [the SDL docs](https://wiki.libsdl.org/SDL_Init), `SDL_INIT_GAMECONTROLLER` implies `SDL_INIT_JOYSTICK`, so this should be a total superset of the previous behavior.
The Controller config UI exposes the Circle mod, only for the Circle pad's modifier, So after changing the binding, it leaves the default binding for the c-stick untouched, and the user is nagged about the (default) D key being bound to something, when trying to bind it to any other button.
With this PR we update the modifier for both the Circle Pad and C-stick.
* Convert Input Count to Frame Count
While recording or playing a movie file, the left side of the status bar currently displays an input counter which shows how many times the emulator has polled for button inputs during the movie. This information is far less easily understandable and less useful for TASing compared to a frame count. The frame count has a linear relationship with input count that can be expressed with Frame Count = 0.255689103308912 * Input Count. Simply put, instead of having a counter that goes up by 3 or 4 every frame, this makes it a counter that goes up by exactly 1 every frame.

This is a port of the initial GameCube adapter input support i added into yuzu emulator.
It requires the same setup as when it was first introduced in yuzu, requiring the Zadig driver be installed for the adapter to allow it to interface with libusb.
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.

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.

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

MakeResult can deduce the contained result type based off the type of

While we're at it, we can also improve some of the allocations and

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.

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

Same behavior, minus the need for an atomic reference count increment
