The current arguments worked by happenstance as games only ever submit
one syncpoint and request one fence back, if a game were to do something
other than this then the arguments would've been parsed entirely wrong.
The format member the IGBPBuffer may not always specify the correct desired format. Using the external format member ensures a valid format is provided when creating the framebuffer.
Fixes homebrew using the wrong framebuffer format.
This was mainly used to keep track of mapped buffers for later unmapping. Since unmap is no longer implemented, this no longer seves a valuable purpose.
Skip unmapping nvdec buffers to avoid breaking the continuity of the VP9 reference frame addresses, and the risk of invalidating data before the async GPU thread is done with it.
This setting is best referred to as a speed limit, as it involves the limits of all timing based aspects of the emulator, not only framerate.
This allows us to differentiate it from the fps unlocker setting.
Now that we have most of core free of shadowing, we can enable the
warning as an error to catch anything that may be remaining and also
eliminate this class of logic bug entirely.
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.
Undefined Behaviour Sanitizer reports a null pointer is being sent to
memcpy, thought it's "guaranteed to never be null". Guard it with an if
statement, and log when the action has been averted.
