interpreter.
The Maxwell 3D engine handles all 3D rendering, currently only non
rendering related methods are implemented. Macros are small pieces of
code that run on the GPU and allow methods to be quickly called for
things like instanced drawing.
These are used to allow the CPU to synchronise with the GPU as it
reaches specific points in its command stream.
Also fixes an nvmap bug where a struct was incorrect.
bugs
An engine is effectively a HW block in the GPU, the main one is the
Maxwell 3D which is used for 3D graphics. Engines can be bound to
individual subchannels and then methods within them can be called
through pushbuffers.
The engine side of the GPFIO is also included, it currently does nothing
but will need to be extended in the future with semaphores.
* 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.
* Make sure icons have a 1:1 ratio
* Use recyclerview padding to increase grid edge margins
* Fix race condition in searching roms
* Use notify insert for adapter
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.
