13a53a9e9d [GPU] Disable the alpha combiner when the color combiner is in "Dot3 RGBA" configuration 2023-06-20 20:46:01 +02:00
fleroviux
a30f9ccd33 [GPU] Treat color and alpha sources as two separate RGBA values 
Previously we fetched the RGB channels of the color source and the alpha channel of the alpha source
and combined these into a single RGBA source value that the source operands are applied to.
This is incorrect. The correct behavior is to fetch the full RGBA color for both the color and alpha
sources and to apply the color operand to the color source and the alpha operand to the alpha source,
i.e. using the *alpha* source R-channel when the alpha operand is "One minus source red".
Only after that we combine both sources into a single RGBA color.

553d23974a Use std::span to pass vertex data 
Starts utilizing
[std::span](https://en.cppreference.com/w/cpp/container/span) to
indicate a non-owning view of a contiguous array of elements rather than
`T* data, usize count`.

fde93381a5 Use std::span for CPU register-state 
Following the trend of #33: `std::span` provides some useful utility
functions like `size_bytes()` and `as_bytes()` and serves as a better
non-owning "chunk of data"-type over just passing around an
`std::array&`.

0199918cd2 Add missing header for regs.hpp 
This enum was using the `u32` type without including `helpers.hpp`, causing weird intermediate compiler errors when making incremental builds.

1aa4dea63e [GPU] Add the remaining two TEV units 
Looks like I overlooked the fact there actually are fix texture combiners,
not just four. The last two texture combiners are easy to miss, because
there are other GPU registers between the first four combiners and the last two.

This commit first implements experimental and incomplete

is implemented. Many sources and combine modes are not implemented yet.

dd0831361d Add .clang-format 
Use the command `clang-format -i tests/**/*.c src/**/*.cpp include/**/*.hpp`
to process all of the project's files.
Using the one from [pcsx-redux](https://github.com/grumpycoders/pcsx-redux/blob/main/src/.clang-format)
as a basis and then made additional edits to be the _least_ disruptive
to the pre-existing formatting patterns.
