Over time a few forward declarations became unnecessary, so we can
remove these to tidy up the header a little bit.
|
|
These were obsoleted in 2c47f8aa1886522898b5b3a73185b5662be3e9f3 but
were accidentally overlooked.

This reverts commit e7733544779f2706d108682dd027d44e7fa5ff4b, reversing
changes made to abbbdc2bc027ed7af236625ae8427a46df63f7e7.

Fixes a hang that may occur when stopping emulation and the VSync thread is blocked on the syncpoint condition variable.
|
|
|
|
|
|
This seems to only be used to protect a later gpu function call. So we can move the lock into that call instead.

- Fixes a hang on shutdown when NVFlinger thread is waiting on a syncpoint that will never occur.
- Commonly observed when stopping emulation in Super Mario Odyssey.

The FPS counter was based on metrics in the nvdisp swapbuffers call. This metric would be accurate if the gpu thread/renderer were synchronous with the nvdisp service, but that's no longer the case.
This commit moves the frame counting responsibility onto the concrete renderers after their frame draw calls. Resulting in more meaningful metrics.
The displayed FPS is now made up of the average framerate between the previous and most recent update, in order to avoid distracting FPS counter updates when framerate is oscillating between close values.
The status bar update frequency was also changed from 2 seconds to 500ms.

Implements the OnClose method of the nvhost_vic device, and removes the remnants of an older implementation.
Also cleans up some of the surrounding code.

nvdrv: Cleanup CDMA Processor on device closure
|
|
This was implicitly done by `is_powered_on = false`, however the explicit method allows us to block until the GPU is actually gone.
This should fix a race condition while removing the other subsystems while the GPU is still active.
|
|
Brings us a step closer to unifying all channels to share a common interface.
|
|
Instead of using a two step initialization to report errors, initialize
the GPU renderer and rasterizer on the constructor and report errors
through std::runtime_error.
|
|
INSERT_PADDING_BYTES_NOINIT is more descriptive of the underlying behavior.
|
|
|
|
- We must always use a GPU thread now, even with synchronous GPU.
|
|
Resolves variable shadowing scenarios up to the end of the OpenGL code
to make it nicer to review. The rest will be resolved in a following
commit.

This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library.
The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data.
To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library.
Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header.
Async GPU is not properly implemented at the moment.

Now that the GPU is initialized when video backends are initialized,
it's no longer needed to query components once the game is running: it
can be done when yuzu is booting.
This allows us to pass components between constructors and in the
process remove all Core::System references in the video backend.
|
|
Add an extra step in GPU initialization to be able to initialize render
backends with a valid GPU instance.
|
|
The puller register array is made up of u32s however the `NUM_REGS` value is the size in bytes, so switch it to avoid making the struct unnecessary large. Also fix a small typo in a comment.

video_core: Fix, add and rename pixel formats
|
|
|
|
Normalizes pixel format names to match Vulkan names. Previous to this
commit pixel formats had no convention, leading to confusion and
potential bugs.
