85d820b1b4 GPU: Handle writes to the CB_DATA method.
Writing to this method will cause the written value to be stored in the currently-set ConstBuffer plus CB_POS.

This method is usually used to upload uniforms or other shader-visible data.

ccb8da1512 GPU: Renamed ShaderType to ShaderStage as that is less confusing. 2018-03-17 18:32:57 -05:00

1d9d9c16e8 GPU: Make the SetShader macro call do the same as the real macro's code.
It'll now set the CB_SIZE, CB_ADDRESS and CB_BIND registers when it's called.

Presumably this SetShader function is binding the constant shader uniforms to buffer 1 (c1[]).

579000e747 GPU: Corrected the parameter documentation for the SetShader macro call.
Register 0xE24 is actually a macro that sets some shader parameters in the register structure.

Macros are uploaded to the GPU at startup and have their own ISA, we'll probably write an interpreter for this in the future.

29feece4b8 GPU: Process command mode 5 (IncreaseOnce) differently from other commands.
Accumulate all arguments before calling the desired method.

Note: Maybe we should do the same for the NonIncreasing mode?

bf310a41b8 GPU: Assert that we get a 0 CODE_ADDRESS register in the 3D engine.
Shader address calculation depends on this value to some extent, we do not currently know what it being 0 entails.

5fb4c718cc GPU: Intercept writes to the VERTEX_END_GL register.
This is the register that gets written after a game calls DrawArrays().

We should collect all GPU state and draw using our graphics API here.

Only QueryMode::Write is supported at the moment.

6cddf9d88e Make a GPU class in VideoCore to contain the GPU state.
Also moved the GPU MemoryManager class to video_core since it makes more sense for it to be there.
