Merge pull request #609 from Subv/clear_buffers 
GPU: Implemented the CLEAR_BUFFERS register.
 7 years ago
Subv c1811ed3d1 GPU: Support clears that don't clear the color buffer. 7 years ago
Subv be51120d23 GPU: Bind and clear the render target when the CLEAR_BUFFERS register is written to. 7 years ago

James Rowe 638956aa81 Rename logging macro back to LOG_* 7 years ago
Subv a3d82ef5d9 Build: Fixed some MSVC warnings in various parts of the code. 7 years ago
Subv dbfc39d214 GPU: Implement sampling multiple textures in the generated glsl shaders. 
All tested games that use a single texture show no regression.

Only Texture2D textures are supported right now, each shader gets its own "tex_fs/vs/gs" sampler array to maintain independent textures between shader stages, the textures themselves are reused if possible.

Subv d57333406d GPU: Partial implementation of long GPU queries. 
Long queries write a 128-bit result value to memory, which consists of a 64 bit query value and a 64 bit timestamp.

In this implementation, only select=Zero of the Crop unit is implemented, this writes the query sequence as a 64 bit value, and a 0u64 value for the timestamp, since we emulate an infinitely fast GPU.

This specific type was hwtested, but more rigorous tests should be performed in the future for the other types.

general: Convert assertion macros over to be fmt-compatible 7 years ago
Subv c16cfbbc6c GPU: Reduce the number of registers of Maxwell3D to 0xE00. 
The rest are just macro shim registers.
 7 years ago
Subv a994446b6e GPU: Move the Maxwell3D macro uploading code to the inside of the Maxwell3D processor. 
It doesn't belong in the PFIFO handler.

video-core: Move logging macros over to new fmt-capable ones 7 years ago
bunnei 239ac8abe2 memory_manager: Make GpuToCpuAddress return an optional. 7 years ago
bunnei 9e11a76e92 memory_manager: Use GPUVAdddr, not PAddr, for GPU addresses. 7 years ago
Subv f208953585 GPU: Added asserts to our code for handling the QUERY_GET GPU command. 
This is based on research from nouveau. Many things are currently unknown and will require hwtests in the future.
This commit also stubs QueryMode::Write2 to do the same as Write. Nouveau code treats them interchangeably, it is currently unknown what the difference is.

Misc gpu improvements
 7 years ago
bunnei 4a8eb6745e maxwell3d: Allow Texture2DNoMipmap as Texture2D. 7 years ago
bunnei 174cba5c58 renderer_opengl: Implement BlendEquation and BlendFunc. 7 years ago
bunnei 1a1af3fda3 gl_rasterizer: Implement indexed vertex mode. 7 years ago
Subv ae58e46036 GPU: Added a function to determine whether a shader stage is enabled or not. 7 years ago
Subv dcc27d6dc1 GPU: Assert when finding a texture with a format type other than UNORM. 7 years ago
Subv 11b4ab9685 GPU: Use the MacroInterpreter class to execute the GPU macros instead of HLEing them. 7 years ago
Subv 1ec8d2123d GPU: Implemented a gpu macro interpreter. 
The Ryujinx macro interpreter and envydis were used as reference.

Macros are programs that are uploaded by the games during boot and can later be called by writing to their method id in a GPU command buffer.

bunnei 33c0bf9dc5 Maxwell3D: Call AccelerateDrawBatch on DrawArrays. 7 years ago
Subv 4697025b73 GPU: Load the sampler info (TSC) when retrieving active textures. 7 years ago
Subv 0ce52b1da2 GPU: Make the debug_context variable a member of the frontend instead of a global. 7 years ago
Subv 2c785bd06c GPU: Added a function to retrieve the active textures for a shader stage. 
TODO: A shader may not use all of these textures at the same time, shader analysis should be performed to determine which textures are actually sampled.
 7 years ago
Subv 1c31e2b3d2 GPU: Implement the Incoming/FinishedPrimitiveBatch debug breakpoints. 7 years ago
Subv 1ad97c75a0 GPU: Implement the MaxwellCommandLoaded/Processed debug breakpoints. 7 years ago
Subv 1b8d798835 GPU: Added a method to unswizzle a texture without decoding it. 
Allow unswizzling of DXT1 textures.
 7 years ago
Subv 71ebc3e90d GPU: Preliminary work for texture decoding. 7 years ago
N00byKing 1d8b6ad13b Clang Fixes 7 years ago
N00byKing ef875d6a35 Clean Warnings (?) 7 years ago
Subv 03156d0c9a GPU: Implement macro 0xE1A BindTextureInfoBuffer in HLE. 
This macro simply sets the current CB_ADDRESS to the texture buffer address for the input shader stage.
 7 years ago
Subv 7b6868e908 GPU: Implement the BindStorageBuffer macro method in HLE. 
This macro binds the SSBO Info Buffer as the current ConstBuffer.
This buffer is usually bound to c0 during shader execution.
Games seem to use this macro instead of directly writing the address for some reason.
 7 years ago
Subv 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.
 7 years ago
Subv aa586fa268 GPU: Store uploaded GPU macros and keep track of the number of method parameters. 7 years ago
Subv 7ac8657432 GPU: Macros are specific to the Maxwell3D engine, so handle them internally. 7 years ago
Subv ccb8da1512 GPU: Renamed ShaderType to ShaderStage as that is less confusing. 7 years ago
Subv 88698c156f GPU: Store shader constbuffer bindings in the GPU state. 7 years ago
Subv 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[]).
 7 years ago
Subv 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.

Subv f93d769a1c GPU: Handle the SetShader method call (0xE24) and store the shader config. 7 years ago

Merge pull request #241 from Subv/gpu_method_call 
GPU: Process command mode 5 (IncreaseOnce) differently from other commands
 7 years ago
Subv 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?

Subv 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.
 7 years ago
Subv 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.
