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
* Core::Timing: Add multiple timer, one for each core
* revert clang-format; work on tests for CoreTiming
* Kernel:: Add support for multiple cores, asserts in HandleSyncRequest because Thread->status == WaitIPC
* Add some TRACE_LOGs
* fix tests
* make some adjustments to qt-debugger, cheats and gdbstub(probably still broken)
* Make ARM_Interface::id private, rework ARM_Interface ctor
* ReRename TimingManager to Timing for smaler diff
* addressed review comments
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`.
