We selectively enable GPU features that we require as enabling all of them might result in extra driver overhead in certain circumstances. Setting them is handled by `QuirkManager` with the new `FEAT_SET` function that ties a quirk with a feature.
We stub alpha testing as it doesn't exist in Vulkan and few titles use it, it can be emulated in the future using a shader patch with manually discarding fragments failing the alpha test function but this'll be added in later as it isn't high priority at the moment and has associated overhead with it so other options might be explored at the time.
It is essential to know what quirks a certain GPU may have to debug an issue, these are now printed at startup into the log alongside all other GPU information. A new `QuirkManager::Summary` function was implemented to provide this functionality.
Implements a basic part of Vulkan blending state which are color logic operations applied on the framebuffer after running the fragment shader. It is an optional feature in Vulkan and not supported on any mobile GPU vendor aside from ImgTec/NVIDIA by default.
Any signals that lead to exception handling being triggered now attempt to flush all logs given that the log mutex is unoccupied, this is to mostly help logs be more complete when exiting isn't graceful.
A lot of calls in Maxwell3D register initialization ended up setting the register to 0 which should be implicit behavior and most calls would be eliminated by the redundancy check which had to be manually disabled. It was determined to be better to move this responsibility to the called function to initialize to state equivalent to the corresponding register being 0. All initialization calls with the argument as 0 have been removed now due to this, it was the vast majority of calls.
Maxwell3D Registers weren't initialized to the correct values prior, this commit fixes that by doing `HandleMethod` calls with all the register values being initialized. This is in contrast to the registers being set without calling the methods in `GraphicsContext` or otherwise resulting in bugs.
The function `GetFormat` was seemingly no longer required due to us never converting from a Vulkan format to a Skyline format, most conversions only went from Skyline to Vulkan and were generally lossy due to certain formats being missing in Vulkan and approximated using channel swizzles. As a result of this, it was pointless to maintain and has now been removed.
Maxwell3D registers relevant to the Vulkan Rasterizer state have been implemented aside from certain features such as per-face polygon modes that cannot be implemented due to Vulkan limitations. A quirk was utilized to dynamically support the provoking vertex being the last vertex as opposed to the first as well.
We require a way to track certain host GPU features that are optional such as Vulkan extensions, this is what the `QuirkManager` class does as it checks for all quirks and holds them allowing other components to branch based off these quirks.
Due to compiler alignment issues, the bitfield member `increment` of `MacroInterpreter::MethodAddress` was mistakenly padded and moved to the next byte. This has now been fixed by making its type `u16` like the member prior to it to prevent natural alignment from kicking in.
This commit added basic shader program registers, they simply track the address a shader is pointed to at the moment. No parsing of the shader program is done within them.
A thread local LoggerContext is now used to hold the output file stream instead of the `Logger` class. Before doing any logging operations, a LoggerContext must be initialized.
This commit will not build successfully on purpose.
Dividers after titles were missing in `ControllerActivity` which made it look inconsistent with `SettingsActivity` which did have them. They have now been added by extending `DividerItemDecoration` to be drawn before any `ControllerHeaderItem`.
The icons in these FABs had the same color as the FAB prior which led them to being invisible. This has been fixed by setting a white tint on them which makes the icons clearly visible.
Additional padding has been added to the text alongside making it be left-aligned rather than center-aligned and justified. A newline has also been added to the copyright notice for Skyline to make it look nicer.
We wanted the color of the modals used by the dialogs to be the same as our regular background color rather than a lighter grey. This has now been enforced with style attributes in the case of `AlertDialog` and `setBackground` in the case of `BottomSheetDialog`.
We inconsistently used `AppCompat`'s `AlertDialog` theme in Settings while using `MaterialComponents`'s theme in Controller Configuration. This has now been fixed by universally using the `MaterialComponents` theme.
The Skyline logo was added to the title area but it ended up being too distracting with a light theme as the logo was designed purely for a white background. Ultimately, even though it looked good with the dark theme we had to remove it.
Aligning the buttons to the bottom of the game image was determined to look odd due to the amount of padding between the title and buttons. They are now back to being below the title but the buttons have been resized with "Play" being a wide button while "Pin" has been replaced with Google Material Icons's "Add To Home Screen" icon and sized down to an icon-only button.
- Logo is now displayed next to the app name
- Remove search bar animation
- New color accent
- Improve visibility of controller binding setting's glyphs
This pushes a set of command buffers into the Host1x command FIFO allocated for the channel, returning fence thresholds that can be waited on for completion,
The Host1x block of the TX1 supports 14 separate channels to which commands can be issued, these all run asynchronously so are emulated the same way as GPU channels with one FIFO emulation thread each. The command FIFO itself is very similar to the GPFIFO found in the GPU however there are some differences, mainly the introduction of classes (similar to engines) and the Mask opcode (which allows writing to a specific set of offsets much more efficiently).
There is an internal Host1x class which functions similar to the GPFIFO class in the GPU, handling general operations such as syncpoint waits, this is accessed via the simple method interface. Other channels such as NVDEC and VIC are behind the 'Tegra Host Interface' (THI) in HW, this abstracts out the classes internal details and provides a uniform method interface ontop of the Host1x method one. We emulate the THI as a templated wrapper for the underlying class.
Syncpoint increments in Host1x are different to GPU, the THI allows submitting increment requests that will be queued up and only be applied after a specific condition in the associated engine is met; however the option to for immediate increments is also available.
This avoids the excessive repetition needed for the case where array
members have no default constructor.
eg:
```c++
std::array<Type, 10> channels{util::MakeFilledArray<Type, 10>(typeConstructorArg, <...>)};
```
nvmap allows mapping handles into the SMMU address space through 'pins'. These are refcounted mappings that are lazily freed when required due to AS space running out. Nvidia implements this by using several MRU lists of handles in order to choose which ones to free and which ones to keep, however as we are unlikely to even run into the case of not having enough address space a naive queue approach works fine. This pin infrastructure is used by nvdrv's host1x channel implementation in order to handle mapping of both command and data buffers for submit.
