bunnei 9f6d305eab shader_bytecode: Decode instructions based on bit strings. 2018-04-20 22:30:56 -04:00
Subv c3a8ea76f1 ShaderGen: Implemented predicated instruction execution. 
Each predicated instruction will be wrapped in an `if (predicate) { instruction_body; }` in the GLSL, where `predicate` is one of the predicate boolean variables previously set by fsetp.
 2018-04-20 21:09:33 -05:00
Subv 0a5e01b710 ShaderGen: Implemented the fsetp instruction. 
Predicate variables are now added to the generated shader code in the form of 'pX' where X is the predicate id.
These predicate variables are initialized to false on shader startup and are set via the fsetp instructions.

TODO:

* Not all the comparison types are implemented.
* Only the single-predicate version is implemented.
 2018-04-20 21:09:33 -05:00
Subv d03fc77475 ShaderGen: Register id 255 is special and is hardcoded to return 0 (SR_ZERO). 2018-04-20 14:57:40 -05:00
Subv fe84842137 ShaderGen: Implemented the fmul32i shader instruction. 2018-04-19 13:46:32 -05:00

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.

Subv 1c31e2b3d2 GPU: Implement the Incoming/FinishedPrimitiveBatch debug breakpoints. 2018-03-24 11:31:50 -05:00

Subv cff7b29bba GPU: Added the TIC registers to the Maxwell3D register structure. 2018-03-19 00:32:57 -05:00
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.
 2018-03-18 19:03:40 -05:00
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.
 2018-03-18 16:50:42 -05:00
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.
 2018-03-18 15:23:24 -05:00
Subv aa586fa268 GPU: Store uploaded GPU macros and keep track of the number of method parameters. 2018-03-18 11:51:46 -05:00
Subv 7ac8657432 GPU: Macros are specific to the Maxwell3D engine, so handle them internally. 2018-03-18 11:51:45 -05:00
Subv ccb8da1512 GPU: Renamed ShaderType to ShaderStage as that is less confusing. 2018-03-17 18:32:57 -05:00
Subv 88698c156f GPU: Store shader constbuffer bindings in the GPU state. 2018-03-17 18:32:57 -05:00
Subv 66dae22790 GPU: Corrected some register offsets and removed superfluous macro registers. 2018-03-17 18:32:56 -05:00
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[]).
 2018-03-17 18:32:55 -05:00
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.

Merge pull request #241 from Subv/gpu_method_call 
GPU: Process command mode 5 (IncreaseOnce) differently from other commands
 2018-03-16 22:28:22 -04:00
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?
 2018-03-16 20:32:44 -05:00
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.
 2018-03-16 19:24:41 -05:00
Subv cbec739e7b GPU: Added Maxwell registers for Shader Program control. 2018-03-16 19:23:11 -05:00
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.

 2018-02-12 12:34:41 -05:00
Subv 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.
 2018-02-11 23:44:12 -05:00
Subv e01a8f2187 GPU: Added a command processor to decode the GPU pushbuffers and forward the commands to their respective engines. 2018-02-11 22:42:48 -05:00
