The version of libcxx shipped with Android NDK is fairly outdated and doesn't contain several features we desire such as C++ 20 ranges. This has been fixed by using libcxx directly from the LLVM Project which has been added as a submodule and can be updated independently of NDK.
We've moved to using a beta AGP as `7.0.2` is breaks `clangd` and other C++ features on Beta/Canary Android Studio. NDK was additionally updated with `mbedtls` to fix warnings caused by it alongside some other minor fixes to code for newer versions of libcxx.
The new AGP has a bug where it does not look for executables specified in `android_gradle_build.json` in `PATH` that includes `ninja` which is provided by the `ninja-build` package on the system rather than Android SDK's CMake on GitHub Actions (Ubuntu 20.04). This has been fixed by symlinking `/usr/bin/ninja` to the project root which is searched in for the `ninja` executable.
Library headers would produce errors that are out of our control and as a result of that, we just want to ignore this. This is possible by including the offending headers as system headers, compilers don't emit any warnings arising from them. This was extended to all libraries rather than just those which currently emitted warnings for consistency's sake.
* Fix handling `SA_EXPOSE_TAGBITS` bit being set in Android 12 `sigaction`
* Fix CMake bug using `CMAKE_INTERPROCEDURAL_OPTIMIZATION_RELEASE` when not supported causing `-fuse-ld=gold` to be emitted as a linker flag
* Support using `VIBRATOR_MANAGER_SERVICE` rather than `VIBRATOR_SERVICE` on Android 12
* Optimize Imports for Kotlin code
* Move away from deprecated APIs in Kotlin or explicitly mark where it's not possible
* Update SDK, NDK and libraries
* Enable Gradle Configuration Cache
Allows the execution of multiple channels at the same time, with locking
being performed on the host GPU scheduler layer, address spaces can be
bound to one or more channels.
This commit introduces the `CommandExecutor` which is responsible for creating and orchestrating a Vulkan command graph comprising of `CommandNode`s that construct all the objects required for rendering. As a result of the infrastructure provided by `CommandExecutor`, `ClearBuffers` could be implemented and be appropriately utilized.
A bug regarding scissors was also determined and fixed in the PR, the extent of them were previously inaccurate and this has now been fixed.
Note: We don't synchronize any textures from the guest for now as this would override the contents on the host, this'll be fixed with the appropriate write tracking but it also results in a black screen for anything that writes to FB
This commit implements a filter by type for any validation layer output, this allows filtering out any logs which may be unnecessary and additionally triggering a breakpoint as required.
An issue concerning the `NDEBUG` flag never being set was fixed, it's now supplied as a release compiler flag. The issue can manifest itself by always relying on a validation layer even though it shouldn't on release, this is why the validation layer was mistakenly disabled entirely previously by using `#ifndef` rather than `#ifdef`.
An issue with the initial layout of a texture being supplied as neither `VK_IMAGE_LAYOUT_UNDEFINED` or `VK_IMAGE_LAYOUT_PREINITIALIZED` was fixed, these cases are now handled by transitioning to those layouts after creating the image rather than supplying it within `initialLayout`.
Another issue was fixed regarding not maintaining a transformation after a surface has been destroyed and recreated existed and manifested itself when the user would go out of the app and come back in, they would see the surface having an identity transformation rather than the desired one.
Fixes bugs with the Texture Manager lookup, fixes `RenderTarget` address extraction (`low`/`high` were flipped prior), refactors `Maxwell3D::CallMethod` to utilize a case for the register being modified + preventing redundant method calls when no new value is being written to the register, and fixes the behavior of shadow RAM which was broken previously and would lead to incorrect arguments being utilized for methods.
Implement the groundwork for the texture manager to be able to report basic overlaps and be extended to support more in the future. The Maxwell3D registers `RenderTargetControl`, `RenderTarget` and a stub for `ClearBuffers` were implemented.
A lot of changes were also made to `GuestTexture`/`Texture` for supporting mipmapping and multiple array layers alongside significant architectural changes to `GuestTexture` effectively disconnecting it from `Texture` with it no longer being a parent rather an object that can be used to create a `Texture` object.
Note: Support for fragmented CPU mappings hasn't been added for texture synchronization yet
Utilize Boost Container's `small_vector` for optimizing allocations, fix certain implicit casting issues and make `ILogger` not output an additional newline in the log when the application supplies one at the end of the log
Implements the 'csrng:' service using C++ <random>'s Mersenne Twister, this does make it insecure for cryptographic purposes but it is pointless to attempt to do this regardless as we cannot ensure that the guest will run in a secure environment which cannot be mutated by an attacker. Used by Prison Princess, Pokemon Cafe Mix, Paint your Pet and more.
We've moved from using an AAR for Mbed TLS to a submodule as the AAR was packaged manually and used from a local repository which ended up being very hacky and resulted in Linter errors, it could also not be updated with ease as it would need to be repackaged. All of these issues have been solved by moving to a git submodule tied to the official Mbed TLS GitHub repository.
VI/IHOSBinder suffered from major inaccuracies in their function due to being quickly thrown together initially with little concern for accuracy, this has now been fixed with them being substantially more accurate now.
This commit reworks the `Texture` class to include a Vulkan Image backing that can be optionally owning or non-owning and swapped in with consideration for Vulkan image layout, it also adds CPU-sided synchronization for the texture objects with FenceCycle. It also makes the appropriate changes to `PresentationEngine` and `GraphicBufferProducer` to work with the new `Texture` class while setting the groundwork for supporting swapchain recreation. It also fixes a log in `IpcResponse` and improves the display mode selection algorithm by further weighing refresh rate.
Implements a wrapper over fences to track a single cycle of activation, implement a Vulkan memory manager that wraps the Vulkan-Memory-Allocator library and a command scheduler for scheduling Vulkan command buffers
Vulkan Device initialization is handled now, it supports required extensions but support for optional extensions/features/properties will come in later when we require those. In addition, we now correctly report the version of Skyline to Vulkan which can be accessed from debugging tools.
There's also a minor change regarding the search pattern for `SkylineLibraries` which now only searches in headers of libraries and it also explicitly excludes the redundant `vulkan.hpp` from the `Vulkan-Headers` repository.
The GPU class has been extended in this for Vulkan initialization, this is done to the point of initializing the instance alongside loading in `VK_LAYER_KHRONOS_validation` which is also now packed into all Debug APKs for Skyline. In addition, `VK_EXT_debug_report` is also initialized and it's output is piped directly into the Logger.
A minor change regarding the type of the `Fps` and `Frametime` globals was changed to `skyline::i32`s which is a more suitable type due to those having a smaller chance of overflowing while being signed as Java doesn't have unsigned integral types.
This is used by games before calling into nvdec in order to clock up the
HW module, it can also be used to request a RAM frequency. Since we
obviously don't emulate the hardware down to this level a basic stub
that provides the correct reponses is enough.
Fixes a crash on first level of Super Mario Odyssey.
We used a custom version of Vulkan-Hpp which split the files a lot prior to avoid any developers needing to manually set IDE settings for IntelliJ to work but this wasn't practical due to how it required modifications to Vulkan-Hpp's generator which would make maintenance extremely difficult. It was determined that we should just add the requirement for changing the IDE settings and use Vulkan-Hpp directly.
We decided to restructure Skyline to draw a layer of separation between guest and host GPU. We're reserving the `gpu` namespace and directory for purely host GPU and creating a new `soc` directory and namespace for emulation of parts of the X1 SoC which is currently limited to guest GPU but will be expanded to contain components like the audio DSP down the line.
This just disables all compiler warnings generated while compiling TZCode as those are irrelevant while compiling Skyline and need to be tackled in that repository.
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 serves as an extension to the initial time commit and combined
they provide a complete implementation of everything application facing
in time.
psc:ITimeZoneService and glue:ITimeZoneService are used to convert
between POSIX and calendar times according to the device location.
Timezone binaries are used during the conversion, details of them can
be read about in the previous commit.
This is based off my own glue RE and Thog's time RE.
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.
These are used for timezone conversions between POSIX and calander time.
Tzdata is in exactly the same format as HOS to allow loading sysarchives
in the future if needed. See its README for more info.
Details on tzcode can be found in its own repo, there are several
changes done Vs the base release to allow for HOS compat.
These only implement the subset of VFS needed for time, implementing
more is difficult due to some issues in the AAsset API which make
support quite ugly. The abstract asset filesystem can be accessed by
services through the OS class allowing other implementations to be used
in the future.
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.
* Fix alignment handling in NvHostAsGpu::AllocSpace
* Implement Ioctl{2,3} ioctls
These were added in HOS 3.0.0 in order to ease handling ioctl buffers.
* Introduce support for GPU address space remapping
* Fix nvdrv and am service bugs
Syncpoints are supposed to be allocated from ID 1, they were allocated
at 0 before. The ioctl functions were also missing from the service map
* Fix friend:u service name
* Stub NVGPU_IOCTL_CHANNEL_SET_TIMESLICE
* Stub IManagerForApplication::CheckAvailability
* Add OsFileSystem Directory support and add a size field to directory entries
The size field will be needed by the incoming HOS IDirectory support.
* Implement support for IDirectory
This is used by applications to list the contents of a directory.
* Address feedback
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.
The GPU has it's own seperate address space to the CPU. It is able to
address 40 bit addresses and accesses the system memory. A sorted vector
has been used to store blocks as insertions are not very frequent.
This gives some useful warnings for less significant issues.
Warnings for reordering are left disabled as they are rather pedantic
and serve little benefit.
This implements the base account service and stubs
InitializeApplicationInfoV0 which is used by Puyo Puyo Tetris. Support
for the entirety of account services will be added in the future.
lm is used by applications to print messages to the system log. Log
messages are made up of a header and then several fields containing
metadata or string messages.
In the case of am, IStorage is used to exchange buffers of data such
as application launch parameters or an applets result. It has no
relation to fsp-srv's IStorage.
Fonts are stored in an array of TTF data with an 8 byte header
containing a magic and an XOR'd length. Instead of requiring users to
provide original Nintendo fonts we pack open source replacements.
They are generated with the scripts here
https://github.com/FearlessTobi/yuzu_system_archives. All the fonts are
licenced under the Open Font or Apache 2 License so we can include them
all freely.
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.
RomFS is a hierarchial filesystem where each level is made up of a
linked list of files and child directories. It is used in NCAs to store
the applications icon as well as by applications themselves for
accessing assets.
Partition FS encapsulates both the HFS0 found in XCIs and the PFS0 used
for ExeFS images and NSPs, it is purely file based and has no support at
all for directories aside from the root.
Mapping and writing segments into memory is now handled by a common
function that can be shared between all loaders. All they need to do now
is to pack each segment into a common struct.
* Correctly handle -WithContext IPC Requests
They should be treated the same as the non WithContext variants.
* Only send domain data on non-control IPC responses
Control IPC doesn't make use of domains so we shouldn't send extra data
in the response.
* Add the IStorage implementation to CMakeLists
- The backing system provides a flexible way to access a a region of
abstract memory.
- It is currently barebones and only has support for reading data but
this will be expanded as necessary.
The current implementations are:
- OsBacking - A backing that abstracts a linux file descriptor
- RegionBacking - A backing that creates a region from a portion of an
existing one
This commit mainly fixes multiple headers in the game list, which was caused by using the wrong variable for the recursive function. In addition, it makes TinyXML2 statically linked to libskyline which makes it the lone shared objects present in APKs.
This makes some tiny changes to audio to make them compliant with the guidelines. In addition, to changing `IUserManager:IUserManager` to `sm:IUserManager`.
We used to link libraries dynamically before, this has obvious disadvantages and extra run-time overhead. Linking them statically instead has a lot of benefits as memory allocations and such don't need to be done independently, interaction with external libraries should be faster in general due to functions not being needed to be called virtually.
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.
