The follow-up to e2457418dae19b889b2ad85255bb95d4cd0e4bff, which
replaces most of the includes in the core header with forward declarations.
This makes it so that if any of the headers the core header was
previously including change, then no one will need to rebuild the bulk
of the core, due to core.h being quite a prevalent inclusion.
This should make turnaround for changes much faster for developers.

core.h is kind of a massive header in terms what it includes within
itself. It includes VFS utilities, kernel headers, file_sys header,
ARM-related headers, etc. This means that changing anything in the
headers included by core.h essentially requires you to rebuild almost
all of core.
Instead, we can modify the System class to use the PImpl idiom, which
allows us to move all of those headers to the cpp file and forward
declare the bulk of the types that would otherwise be included, reducing
compile times. This change specifically only performs the PImpl portion.

As means to pave the way for getting rid of global state within core,
This eliminates kernel global state by removing all globals. Instead
this introduces a KernelCore class which acts as a kernel instance. This
instance lives in the System class, which keeps its lifetime contained
to the lifetime of the System class.
This also forces the kernel types to actually interact with the main
kernel instance itself instead of having transient kernel state placed
all over several translation units, keeping everything together. It also
has a nice consequence of making dependencies much more explicit.
This also makes our initialization a tad bit more correct. Previously we
were creating a kernel process before the actual kernel was initialized,
which doesn't really make much sense.
The KernelCore class itself follows the PImpl idiom, which allows
keeping all the implementation details sealed away from everything else,
which forces the use of the exposed API and allows us to avoid any
unnecessary inclusions within the main kernel header.

gpu: Make memory_manager private
|
|
Makes the class interface consistent and provides accessors for
obtaining a reference to the memory manager instance.
Given we also return references, this makes our more flimsy uses of
const apparent, given const doesn't propagate through pointers in the
way one would typically expect. This makes our mutable state more
apparent in some places.

Many containers within the standard library provide different behaviors
based on whether or not a move constructor/assignment operator can be
guaranteed not to throw or not.
Notably, implementations will generally use std::move_if_noexcept (or an
internal implementation of it) to provide strong exception guarantees.
If a move constructor potentially throws (in other words, is not
noexcept), then certain behaviors will create copies, rather than moving
the values.
For example, consider std::vector. When a std::vector calls resize(),
there are two ways the elements can be relocated to the new block of
memory (if a reallocation happens), by copy, or by moving the existing
elements into the new block of memory. If a type does not have a
guarantee that it will not throw in the move constructor, a copy will
happen. However, if it can be guaranteed that the move constructor won't
throw, then the elements will be moved.
This just allows ResultVal to be moved instead of copied all the time if
ever used in conjunction with containers for whatever reason.

kernel/error: Amend several error codes
|
|
core: Namespace all code in the arm subdirectory under the Core namespace
|
|
svc: Return process title ID if queried in GetInfo()
|
|
PL:U Added SharedFonts loading via TTF
|
|
hid: Move core include to cpp file
|
|
Rightnow, in games use GetAvailableLanguageCodes(), there is a WriteBuffer() with size larger than the buffer_size. (Core Critical core\hle\kernel\hle_ipc.cpp:WriteBuffer:296: size (0000000000000088) is greater than buffer_size (0000000000000078))
0x88 = 17(languages) * 8
0x78 = 15(languages) * 8
GetAvailableLanguageCodes() can only support 15 languages.
After firmware 4.0.0 there are 17 supported language instead of 15, to enable this GetAvailableLanguageCodes2() need to be used.
So GetAvailableLanguageCodes() will be caped at 15 languages.

We can make this error code an alias of the resource limit exceeded
error code, allowing us to get rid of the lingering 3DS error code of
the same type.
|
|
We can treat this as an alias of TooLarge for documentation purposes.
This also lets us get rid of another lingering 3DS-related error code.
|
|
This replaces the lingering 3DS constant with the proper one, and
utilizes it within HandleTable's Create() member function.

filesystem: Fix typo in log message
|
|
We already have the variable itself set up to perform this task, so we
can just return its value from the currently executing process instead
of always stubbing it to zero.
|
|
file_sys: Add support for NAX archives
|
|
Gets all of these types and interfaces out of the global namespace.
|
|
This isn't required to be in the header. Instead, directly include what
this header needs and move it to the cpp file where it belongs.

* Added GetBootMode
Used by homebrew
* Added enum for GetBootMode
|
|
|
|
Allows frontend to create registration caches for use before a game has booted.

By having the following TTF files in your yuzu sysdata directory. You can load sharedfonts via TTF files.
FontStandard.ttf
FontChineseSimplified.ttf
FontExtendedChineseSimplified.ttf
FontChineseTraditional.ttf
FontKorean.ttf
FontNintendoExtended.ttf
FontNintendoExtended2.ttf
|
|
Should fix any compile errors
|
|
* Added bfttf loading
We can now load system bfttf fonts from system archives AND shared memory dumps. This allows people who have installed their system nand dumps to yuzu to automatically get shared font support. We also now don't hard code the offsets or the sizes of the shared fonts and it's all calculated for us now.
* Addressed plu fixups
* Style changes for plu
* Fixed logic error for plu and added more error checks.

vfs: Replace mode.h include with forward declarations where applicable
|
|
Avoids the need to rebuild these source files if the mode header
changes.
|
|
Gets rid of the potential for C array-to-pointer decay, and also makes
pointer arithmetic to get the end of the copy range unnecessary. We can
just use std::array's begin() and end() member functions.
|
|
romfs_factory, service/filesystem: Use forward declarations where applicable
|
|
Avoids the need to rebuild multiple source files if the filesystem code
headers change.
This also gets rid of a few instances of indirect inclusions being
relied upon
|
|
acc/profile_manager: General cleanup
|
|
filesystem: Add support for loading of system archives
|
|
This is only used in a shared_ptr, so we can forward declare it.
|
|
We have an overload of WriteBuffer that accepts containers that satisfy
the ContiguousContainer concept, which std::array does, so we only need
to pass in the array itself.
|
|
Arranges them in the order the members would be initialized
|
|
This is no longer used, so it can be removed.
|
|
Makes it a little bit more self-documenting.
|
|
Given the source and destination types are the same std::array type, we
can simply use regular assignment to perform the same behavior.
|
|
arrays
Avoids the need to repeatedly specify the whole array type in multiple
places.
|
|
ProfileInfo is quite a large struct in terms of data, and we don't need
to perform a copy in these instances, so we can just pass constant
references instead.
|
|
This doesn't modify the passed in array, so this can be a const
reference.
|
|
This can just be constexpr like the others
|
|
operator bool
We can use the constructor initializer list and just compare the
contained u128's together instead of comparing each element
individually. Ditto for comparing against an invalid UUID.
|
|
This avoids needing to dump the contents of <random> into other files
that include the profile manager header.
