Adds missing include for common/logging/log.h in gpu.h which was causing
compilation failures on Android. This header is needed for logging
functionality used in GPU-related operations.
The include was previously indirectly available through other headers,
but making it explicit improves code clarity and prevents potential
future compilation issues.

Relaxes validation checks in the NVDRV GPU service and improves error notifier
handling to prevent potential hangs. Key changes:
- Remove strict size validation in SetErrorNotifier
- Relax GPFIFO entry count validation to only check for non-zero values
- Add proper error notifier state tracking in GPU class
- Improve debug logging messages
The previous strict validation was causing issues with some games like ACNH.
These changes maintain necessary checks while being more permissive with
edge cases that don't impact functionality.
Technical changes:
- Store error notifier state in GPU class for future implementation
- Remove upper bound check on GPFIFO entries
- Simplify error notifier setup flow
This should resolve hanging issues while maintaining core functionality.

Implements several previously stubbed functions in the NVDRV service:
- Initialize proper transfer memory handling
- Add error notifier configuration
- Implement channel timeout and timeslice management
- Add object context allocation and tracking
- Add GPU interface stubs for new functionality
The changes improve the accuracy of GPU-related operations while maintaining
compatibility with the existing codebase. All functions now properly validate
parameters and handle endianness correctly using _le types.

- In commit b3facaa6bb30cdc39f2b7d632fef1e3bfeee7785, the copyright header was
updated to include "Citron Homebrew Project" across multiple files, regardless
of whether any contributions were made.
- This commit removes the incorrect attribution and reverts the copyright header
to its previous state.
- Copyright attribution should only be added when meaningful contributions have
been made to the file.
- This commit ensures proper compliance with copyright standards and maintains
correct attribution to the respective contributors.
- Special thanks to Tachi for pointing out the need for these corrections and
ensuring that proper attribution practices are followed.
|
|
- Replaced all references to the old project name with Citron.
- Added Citron copyright information alongside existing notices in all files.

This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.

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.

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.

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

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.
