* Fix alignment handling in NvHostAsGpu::AllocSpace
* Implement Ioctl{2,3} ioctls
These were added in HOS 3.0.0 in order to ease handling ioctl buffers.
* Introduce support for GPU address space remapping
* Fix nvdrv and am service bugs
Syncpoints are supposed to be allocated from ID 1, they were allocated
at 0 before. The ioctl functions were also missing from the service map
* Fix friend:u service name
* Stub NVGPU_IOCTL_CHANNEL_SET_TIMESLICE
* Stub IManagerForApplication::CheckAvailability
* Add OsFileSystem Directory support and add a size field to directory entries
The size field will be needed by the incoming HOS IDirectory support.
* Implement support for IDirectory
This is used by applications to list the contents of a directory.
* Address feedback
This commit refactors the C++ end of Input so it'll be in line with the rest of the codebase and be ready for the extension with multiple players and controller configuration.
This commit contains the C++ side of the initial Input implementation, this is based on the work done in the `hid` branch in `bylaws/skyline`.

* Rework VFS to support creating and writing files and introduce OsFileSystem
OsFileSystem abstracts a directory on the device using the filesystem API.
This also introduces GetEntryType and changes FileExists to use it.
* Implement the Horizon FileSystem APIs using our VFS framework
Horizon provides access to files through its IFileSystem class, we can
closely map this to our vfs::FileSystem class.
* Add support for creating application savedata
This implements basic savedata creation using the OsFileSystem API. The
data is stored in Skyline's private directory is stored in the same
format as yuzu.
The GPU has it's own seperate address space to the CPU. It is able to
address 40 bit addresses and accesses the system memory. A sorted vector
has been used to store blocks as insertions are not very frequent.
This gives some useful warnings for less significant issues.
Warnings for reordering are left disabled as they are rather pedantic
and serve little benefit.
This implements the base account service and stubs
InitializeApplicationInfoV0 which is used by Puyo Puyo Tetris. Support
for the entirety of account services will be added in the future.
lm is used by applications to print messages to the system log. Log
messages are made up of a header and then several fields containing
metadata or string messages.
In the case of am, IStorage is used to exchange buffers of data such
as application launch parameters or an applets result. It has no
relation to fsp-srv's IStorage.
Fonts are stored in an array of TTF data with an 8 byte header
containing a magic and an XOR'd length. Instead of requiring users to
provide original Nintendo fonts we pack open source replacements.
They are generated with the scripts here
https://github.com/FearlessTobi/yuzu_system_archives. All the fonts are
licenced under the Open Font or Apache 2 License so we can include them
all freely.
An NSP (Nintendo Submission Package) is effectively a PFS0 containing
NCAs, there are also tickets and a CNMT file which contains metadata
about updates. The current implementation is very basic and only
support Control and Program NCAs which is enough for loading games.
Support for updates and dlc will be added at a later date.
Nintendo Content Archives are used to store the assets, executables
and updates of applications. They support holding either a PFS0 or a
RomFS.
An NCA's ExeFS can be loaded by placing each NSO sequentially into
memory, starting with rtld which will link them together.
Currently only decrypted NCAs are supported, encryption and BKTR
handling will be added at a later time.
RomFS is a hierarchial filesystem where each level is made up of a
linked list of files and child directories. It is used in NCAs to store
the applications icon as well as by applications themselves for
accessing assets.
Partition FS encapsulates both the HFS0 found in XCIs and the PFS0 used
for ExeFS images and NSPs, it is purely file based and has no support at
all for directories aside from the root.
Mapping and writing segments into memory is now handled by a common
function that can be shared between all loaders. All they need to do now
is to pack each segment into a common struct.
* Correctly handle -WithContext IPC Requests
They should be treated the same as the non WithContext variants.
* Only send domain data on non-control IPC responses
Control IPC doesn't make use of domains so we shouldn't send extra data
in the response.
* Add the IStorage implementation to CMakeLists
- The backing system provides a flexible way to access a a region of
abstract memory.
- It is currently barebones and only has support for reading data but
this will be expanded as necessary.
The current implementations are:
- OsBacking - A backing that abstracts a linux file descriptor
- RegionBacking - A backing that creates a region from a portion of an
existing one
