By importing guest memory directly onto the host GPU we can avoid many of the complexities that occur with memory tracking as well as the heavy performance overhead in some situations. Since it's still desired to support the traditional buffer method, as it's faster in some cases and more widely supported, most of the exposed buffer methods have been split into two variants with just a small amount of shared code. While in most cases the code is simpler, one area with more complexity is handling CPU accesses that need to be sequenced, since we don't have any place we can easily apply writes to on the GPFIFO thread that wont also impact the buffer on the GPU, to solve this, when the GPU is actively using a buffer's contents, an interval list is used to keep track of any GPFIO-written regions on the CPU and any CPU reads to them will instead be directed to a shadow of the buffer with just those writes applied. Once the GPU has finished using buffer contents the shadow can then be removed as all writes will have been done by the GPU.
The main caveat of this is that it requires tying host sync to guest sync, this can reduce performance in games which double buffer command buffers as it prevents us from fully saturating the CPU with the GPFIFO thread.
Extends the profile picture stub into a full-fledged implementation with the ability for users to set their profile picture in settings while having the Skyline icon as the default profile picture.
* Close the input and output file streams before moving the output file to the final destination
* Clean up the destination path before moving the new file
* Introduce a `ImportResult` return value to differentiate between the possible causes of import errors
* Display more meaningful error messages in the UI
The old message was being misinterpreted as if the device's gpu was not supported by the emulator. Reword that message to explicitly mention custom drivers.
Readback can be especially slow on mobile due to the varying load pattern it creates which often prevents the CPU/GPU from clocking up. Since some games perform texture readback but don't actually use it for anything significant implement a hack to skip it and significantly improve performance in such cases.
Needed for games such as AC:NH.
The `Auto` option automatically selects a region based on the currently selected system language.

As part of this commit, a new preference category for debug settings is being introduced. All future settings only relevant for debugging purposes will be put there. The category is hidden on release builds.
The FPS is implicitly bound to the refresh rate due to the timestamp being that of the presentation time, this leads to a misleading FPS figure for disabled frame throttling. It has now been fixed by using the frame submission time rather than the presentation time when frame throttling is disabled and to make this more apparent the color of the OSD FPS has been changed.
This preference launches `GpuDriverActivity` for managing custom gpu drivers. When the device has an incompatible GPU, the preference will be disabled and greyed out.
The activity adds the following functionalities:
* Lists installed drivers
* Allows the user to install new drivers, or remove installed ones
* Allows the user to select the driver that will be used by the emulator
With the Skyline document provider, easy access to the internal directory is required which may be hard to navigate to through the system file manager. This adds an option in settings to directly open up the directory in the system file manager.
We want to utilize features from C++ 20 ranges but they haven't been entirely implemented in libc++ so in the meantime we use the reference implementation for it which is Ranges v3.
* Update licenses for dependent projects
* Add copyright notices (as provided)
* Revamp styling for `LicenseDialog`
* Fix invisible `PreferenceDialog` buttons in Settings
* Consolidating color variables into `colorPrimary`, `backgroundColor` and `backgroundColorVariant`
* Use `com.google.android.flexbox:flexbox:3.0.0` (Google Maven) rather than `com.google.android:flexbox:2.0.1` (Bintray)
This commit adds in the UI for Controller Configuration to Settings, in addition to introducing the storage and loading of aforementioned configurations to a file that can be saved/loaded at runtime. This commit also fixes updating of individual fields in Settings when changed from an external activity.
This commit focuses on making the UI completely usable using a controller so that a user won't have to switch between their device's touch screen and a controller constantly.
