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 significantly increases the accuracy of the prior HID code due to testing on the Switch. It is now fully accurate in all supported scenarios, them being assignment mode, orientation, color writes and system properties. In addition, review comments were addressed and fixed in the PR.
* 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.
As the stack is automatically mapped in the guest by `clone` we do not
need to explicitly map it. This adds a flag to solve the issue.
Also mark the stack as stack rather than reserved.
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.
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.
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 fixes GitHub Actions builds which were broken due to an outdated version of Android NDK. In addition, it moves all stack to shared memory.
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 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.
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 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 adapts the C++ backend to the Kotlin frontend by moving to usage of file descriptors and, provides an interface to access frontend code via JNI which is used to check the state of the activity and catch events such as surface destruction. In addition, this commit fixes some minor linting errors and changes the CMake version to 3.10.2+.
This commit adds logging to almost all SVCs with the exception of svcGetSystemTick and adds accurate error handling to them. It also improves how KSharedMemory is handled.
The following things were fixed:
* KSharedMemory
* KSyncObject (and how waiting on them works)
* Inclusion of Headers
What was added:
* Transfer Memory
* svcSleepThread
