core.h is kind of a massive header in terms what it includes within
itself. It includes VFS utilities, kernel headers, file_sys header,
ARM-related headers, etc. This means that changing anything in the
headers included by core.h essentially requires you to rebuild almost
all of core.
Instead, we can modify the System class to use the PImpl idiom, which
allows us to move all of those headers to the cpp file and forward
declare the bulk of the types that would otherwise be included, reducing
compile times. This change specifically only performs the PImpl portion.
We move the initialization of the renderer to the core class, while
keeping the creation of it and any other specifics in video_core. This
way we can ensure that the renderer is initialized and doesn't give
unfettered access to the renderer. This also makes dependencies on types
more explicit.
For example, the GPU class doesn't need to depend on the
existence of a renderer, it only needs to care about whether or not it
has a rasterizer, but since it was accessing the global variable, it was
also making the renderer a part of its dependency chain. By adjusting
the interface, we can get rid of this dependency.
* FinishInitalize needed for 3.0.1+ games
* nvdrv:s and nvdrv:t both use NVDRV
* Most settings return 0 on hardware, disabled NV_MEMORY_PROFILER for now.
NVN_THROUGH_OPENGL & NVRM_GPU_PREVENT_USE are a few interesting settings to look at. Carefully choosing settings can help with drawing graphics later on
* Initial /dev/nvhost-gpu support
* ZCullBind
* Stubbed SetErrorNotifier
* Fixed SetErrorNotifier log, Added SetChannelPriority
* Allocate GPFIFO Ex2, Allocate Obj Ctx, Submit GPFIFO
* oops
* Fixed up naming/structs/enums. Used vector instead of array for "gpfifo_entry"
* Added missing fixes
* /dev/nvhost-ctrl-gpu
* unneeded struct
* Forgot u32 in enum class
* Automatic descriptor swapping for ioctls, fixed nvgpu_gpu_get_tpc_masks_args being incorrect size
* nvdrv#QueryEvent
* Renamed logs for nvdrv
* Refactor ioctl so nv_result isn't needed
* /dev/nvhost-as-gpu
* Fixed Log service naming, CtxObjects now u32, renamed all structs, added static_asserts to structs, used INSERT_PADDING_WORDS instead of u32s
* nvdevices now uses "Ioctl" union,
* IoctlGpfifoEntry now uses bit field
* final changes
