Add Tracing for SVCs, Services, NVDRV, and Synchronization Primitives. In addition, fix `TRACE_EVENT_END("guest")` being emitted when a signal is received while being in the guest rather than host which would cause an exception. This commit also disables warnings for the Perfetto library as we do not control fixing them.
This reimplements our time backend to be significantly more accurate to
the real PSC and provides complete implementations for every time IPC
allowing many newer games to work properly.
Time is unique in its use of glue services, the core sysmodule is fully
isolated and doesn't interface with any other services. Glue is instead
used where that is needed (e.g. for fetching settings), this distinction
is also present in our implementation.
Another unique feature of time is its global state, as time is
calibrated from the start of the service its state cannot be lost as
that would result in the application offsetting time incorrectly
whenever it closed a session.
A large proportion of this is based off of Thog's 9.0.0 PSC reversing.
This addresses all CR comments including more codebase-wide changes arising from certain review comments like proper usage of its/it's and consistent contraction of it is into it's.
An overhaul was made to the presentation and formatting of `KThread.h` and `LoadBalance` works has been superseded by `GetOptimalCoreForThread` which can be used alongside `InsertThread` or `MigrateToCore`. It makes the API far more atomic and neater. This was a major point of contention for the design prior, it's simplified some code and potentially improved performance.
We've moved to using RS and GS from ASCII as delimiters rather than
'\n' and '|', this allows more robust parsing and increases the
readability of the log files
An exceptional signal handler allows us to convert an OS signal into a C++ exception, this allows us to alleviate a lot of crashes that would otherwise occur from signals being thrown during execution of games and be able to handle them gracefully.
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.
This commit mainly finishes up refactor by fixing everything brought up in the CR + Improving NCE somewhat and actually killing the child processes properly now.
We earlier moved to LGPLv3.0 or Later. This was a mistake as what we wanted was being able to link to proprietary libraries but LGPL is the opposite and it allows linking proprietary libraries to libskyline instead. After further consideration, we've moved to MPL-2.0, it allows linking to proprietary libraries and is a standardized license as compared to adding an exception to GPL.
