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.
unmapped regions
svcQueryMemory will return a valid descriptor for anything in the
address space, from 0 to 1 << addrSpaceBits, this was handled
incorrectly before and we were only returning descriptors if the
address was in a mapped region.
If an address in an unmapped region is requested then the extents of the
unmapped region up to the address space end are returned. If the address
requested is outside of the address space then the extents of the
inaccessible address space are returned.
To facilitate this support was added to MemoryManager::Get for
generating the extents of unmapped regions using the chunk list.
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.
Not zeroing the sample buffer causes issues when a voice is started but
is playing no samples. The system event handling was also reworked
according to Thog's info.
This fixes two bugs in IPC that were discovered when running Puyo Puyo
Tetris.
The CloneCurrentObject control IPC will now correctly return the handle
of the newly created object through move handles, rather than pushing it
as a result.
The size array of u16s with the sizes of each C buffer is now taken into
account when reading them. Before this change C buffers were entirely
broken.
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
This commit adds support for reading the RomFS data from an NRO and
obtaining an IStorage handle to it through 'OpenDataStorageByCurrentProcess'.
There is currently only support for reading and no support
for enlarging or writing.
Also fixup a few capitalisation issues.
- 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 makes a few improvements to the UI/UX:
* Crop Game Icons to ImageView
* Controller Support for Game List
* EmulationActivity is fullscreen now
This commit does some minor renaming/reordering in IPC and adds support for strings to IPC Push/Pop. It also fixes a tiny regression with the frametime display.
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 commit mainly fixes the issue with `AppDialog` where it didn't expand fully in landscape leading to UX issues. In addition, a race condition was fixed in `MainActivity::addEntries`, in regards to `foundCurrent` being returned incorrectly. The text in the performance counters were also made yellow and much more opaque.
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 refactors `AppDialog` by bringing it in line with the guidelines. In addition, it improves the design of it substantially by modifying the layout and making it a `BottomSheetDialogFragment`.
This refactors all preferences and loaders in regards to This commit mainly refactors the adapters by adding spacing, comments and following other guidelines. In addition, preferences are now moved into their own sub-package and `LicensePreference` has a minor UI update.
With `RecyclerView` being used rather than `ListView` or `GridView`. It's now possible to display the items in a flexible manner and so support for a grid view in addition to the already existing list view was added in.
This commit mainly refactors the adapters by adding spacing, comments and following other guidelines. In addition, it moves from using `BaseAdapter` to `RecyclerView.Adapter` which leads to much cleaner adapter classes.

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.
