Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2025-05-16T15:30:53+00:00 2025-05-16T15:30:53+00:00 Mukund Keshava mkeshava@nvidia.com 2025-05-16T15:30:53+00:00 urn:sha1:1fd7b2296d8360c245a0c732e7f842876533f92a Fixes #7127 2020-01-21T14:38:10+00:00 jsmall-nvidia jsmall@nvidia.com 2020-01-21T14:38:10+00:00 urn:sha1:47392bc72b826b4ad427b703391a77e697735a65 * Add test result for compile-to-cuda * Add RAII for some CUDA types to simplify usage. * First pass handling of some instrinsics on CUDA (for example transcendentals) * CUDA working with built in intrinsics. * Add missing CUDA prelude intrinsics. * CUDA matches CPU output on simple-cross-compile.slang * First pass at hlsl-scalar-float-intrinsic.slang test. * Fix smoothstep impl on CUDA and CPU. * Fixed step intrinsic on CUDA/CPU. * Added operator[] to Matrix for C++, to allow row access. Needs a fix for CUDA. * Fixed warning on clang build. 2020-01-17T14:15:06+00:00 jsmall-nvidia jsmall@nvidia.com 2020-01-17T14:15:06+00:00 urn:sha1:a8669ade5cb3add8b9ce08e2c3bd96e93190bca8 * First pass at BindLocation. * Added BindSet::init - for initializing with two input constant buffers. Needs better name, and perhaps should be another class. * Fix handling of constant buffer stripping. Improved initialization. * Trying to generalize BindLocation a little more. Split out CPULikeBindRoot. * More work to make BindLocation et al work with non uniform bindings. * Added parsing to a location. * WIP: Trying to get CPU working with BindLocation. * Describe problem of knowing the type of the reference point in the binding table. * More ideas on getBindings fix. * Remove BindSet as member of BindLocation. * Added BindLocation::Invalid * Made BindLocation able to be key in hash * Use BindLocation for bindings on BindingSet. * Added cuda and nvrtc categories to test infrastructure. Disabled CUDA synthetic tests by default. Fixed such that all tests now produce something in BindLocation style. * Use m_userIndex instead of m_userData on Resource. Move the binding setup out of cpu-compute-util (as no longer CPU specific) * Removed CPUBinding - used BindLocation/BindSet instead. Fixed some bugs around indexOf around uniform indirection. * Renamed BindSet::Resource -> BindSet::Value. * Document BindLocation. * Fixes for Clang/GCC Improve invariant requirement handling when constructing from BindPoints. * WIP: First attempt to run CUDA kernel. * Fix some issues around doing CUDA kernel launch. * Fix issues around use of cudaMemCpy . * Better cuda runtime error checking mechanism. * Fixed bug in passing parameters to cuda kernel launch. Simplified initialisation of context. * WIP: Fix CUDA runtime issues. * Add explicit CUDA synchronize so failures don't appear on implicit ones. * Fix problem emitting non shared variable on CUDA. * Fix some typos in CUDA layout. Use just a pointer for now for CUDA StucturedBuffer. * Arg order for CUDA launch was wrong. * First compute kernel runs on CUDA. 2019-12-19T16:23:14+00:00 jsmall-nvidia jsmall@nvidia.com 2019-12-19T16:23:14+00:00 urn:sha1:e3fe0319467546bae070137c58dcf8f9fbe93c79 * CPPCompiler -> DownstreamCompiler * Added DownstreamCompileResult to start abstraction such that we don't need files. * * Split out slang-blob.cpp * Made CompileResult hold a DownstreamCompileResult - for access to binary or ISlangSharedLibrary * Keep temporary files in scope. * Add a hash to the hex dump stream. * Move all file tracking into DownstreamCompiler. * WIP support for nvrtc. * WIP: Adding support for nvrtc compiler. Adding enum types, wiring up the nvrtc into slang. * Fix remaining CPPCompiler references. * Fix order issue on target string matching. * Use ISlangSharedLibrary for nvrtc. * Use DownstreamCompiler for nvrtc. * WIP first pass at compilation win nvrtc. * Added testing if file is on file system into CommandLineDownstreamCompiler. Added sourceContentsPath. * Make test cuda-compile.cu work by just compiling not comparing output. * Genearlize DownstreamCompiler usage. * Fix warning on clang. * Remove CompilerType from DownstreamCompiler. * Use DownstreamCompiler interface for all compilers. NOTE for FXC, DXC and GLSLANG this doesn't mean using 'compile' - it's still extracting functions from shared library. * Replace DownstreamCompiler::SourceType -> SlangSourceLanguage * Replace _canCompile with something data driven. * Fix compiling on gcc/clang for DownstreamCompiler. * Moved some text conversions into DownstreamCompiler. * Fix problem on non-vc builds with not having return on locateCompilers for VS. * Change so no warning for code not reachable on locateCompilers for vs. * WIP: CUDA code generation - currently just using CPU layout and HLSL. * emitXXXForEntryPoint -> emitEntryPointSource emitSourceForEntryPoint -> emitEntryPointSourceFromIR Fix up generating cuda to get PTX. * WIP emitting cuda for IR. * Small improvements to CUDA ouput. * Disable the CUDA emit test, as output not currently compilable.
