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.
This commit mainly fixes the problem with process leakage before where the guest process wouldn't be killed. In addition, it clears up the problem with naming differences with PID/TID where purely PID was used before but that term is generally used to refer to the PGID. So, `KProcess` has a `pid` member but `KThread` has a `tid` member.
This commit fixes a lot of style errors throughout the project by letting the Android Studio Formatter fix them. This commit also splits the Circular Buffer into it's own file.
This commit adds performance statistics to the emulator that can be toggled in preferences. The layout of `EmulationActivity` was also changed from `ConstraintLayout` to `RelativeLayout` due to poor performance of the former.
This optimizes a lot of audio by using a circular buffer rather than queues. In addition to handling device disconnection using oboe callbacks and fix bugs in regards to audio saturation.
This commit adds mutexes to the logger so they produce a valid log file rather than breaking due to a race condition. It also introduced `util::MakeMagic` so the magic functions are far more clear. A small refactor of IPC was also done which cleared up some of the for loops.
This commit mainly refactors all activities to bring them in-line with the guidelines and makes certain improvements such as using `Snackbar`s rather than `Toast`s where possible, Using `CoordinatorLayout` to allow the app bar to hide itself when possible, the app bar has also been consolidated into it's own layout file to increase layout redraw performance as existing views can be used.
This commit fixes a tiny inaccuracy with the VMM which was a problem with block insertion, The mutexes on the other hand had a minor issue regarding owner checks.
This makes some tiny changes to audio to make them compliant with the guidelines. In addition, to changing `IUserManager:IUserManager` to `sm:IUserManager`.
This refactored common by:
* Moving out as many constants to class/function local scopes from being declared in `common`
* Spacing out common and any function to which a constant was moved out to
* Fixing comments here and there
In addition, some naming inconsistencies were fixed as well.
This commit mainly just refactors NCE by adding spacing and fixing other minor errors. In addition, it adds comments to `nce/guest.h` and `nce/instructions.h`.
This commit addresses the incorrect hierarchy of the GPU and refactors them at the same time. Now, the hierarchy much closely matches HOS. This commit also introduces a texture classes, albeit they're not complete and only partially implemented.
This commit mainly fixes GitHub Actions builds which were broken due to an outdated version of Android NDK. In addition, it moves all stack to shared memory.
Remove looping support - it is slow and no services use it.
Store service name in in base service class - removes the
need for having sub-services in the service name map.
General code clean up - remove {} from single if statements etc.
This commit fixed the issues outlined in the CR (Mainly correlated to formatting), moves to a sorted vector from a sorted list for the memory map in addition to using binary search for sorting through rather than iteratively and fixes item duplication in the game list when directory is changed in Settings.
This commit mainly fixes GroupMutex and clock rescaling. In addition, clock rescaling is no longer performed if the CNTFRQ_EL0 of the host device is same as that of the Switch (19.2MHz) which is fairly common on higher end devices.
This commit adds working conditional variables, in addition to the mutex and threading implementation. It directly depends on the memory optimization from the previous commit to be able to perform atomic operations on the mutex.
This commit further improves the memory implementation by using shared memory for all allocations so we won't have to depend on a kernel call for doing any host <-> guest memory transfers.
This commit adds support for threading and mutexes. However, there is also a basis of conditional variables but these don't work due to the lack of a shared memory model between the guest and host. So, conditional variables will be deferred to after the shared memory model is in place.
Forces all registers to be saved before signalling to the kernel that we
are ready; without this the kernel may read incorrect context data
causing undefined behaviour.
This commit does a major refactor of the memory implementation, it forms a memory map which is far cleaner than trying to access it through a handle table lookup. In addition, it creates a common interface for all memory kernel objects: KMemory from which all other kernel memory objects inherit. This allows doing resizing, permission change, etc without casting to the base memory type.
This commit causes Android Studio to use the .clang-tidy file for configuration and removes madvise DO_FORK/DONT_FORK calls as they cause problems on many devices and are mostly unnecessary.
This commit makes the kernel completely thread-safe and fixes an issue that caused libNX games to not work due to an error with KSharedMemory. In addition, implement GroupMutex to allow the kernel threads to run in parallel but still allow them to not overlap with the JNI thread.
This commit makes the kernel thread safe in some instances (but not fully) and showcases the significantly improved performance over the ptrace method used prior. In addition, scanning for ROMs is now done asynchronously.
This commit is a huge step in the direction of better performance, as we move from ptrace to junction branching and have kernel call overhead similar to that of a native kernel call! In addition, this sets the base for the kernel to go fully multi-threaded. However, the kernel is currently not thread-safe and therefore this commit currently causes a crash.
This commit removes support for more than one guest processes as it requires a fair bit of extra code to support in addition the HLE service implementations don't support it anyway.
This commit is the start of moving towards a lockless and faster kernel which can run multiple independent threads with fast userspace synchronization.
