      Lei Wang authored
      * [Enhancement] Add read-only parameter annotation for CUDA codegen
      
      * Introduced the `AnnotateReadOnlyParams` transformation to annotate read-only handle parameters in PrimFuncs, enabling the generation of `const` qualifiers in CUDA codegen.
      * Updated `PrintFunctionSignature` and `AddFunction` methods to utilize the new attribute `tl.readonly_param_indices`, enhancing performance by allowing read-only cache loads.
      * Modified the optimization pipeline to include the new annotation step, improving the overall efficiency of the code generation process.
      
      * lint fix
      
      * [Dependency] Update apache-tvm-ffi version to >=0.1.3
      
      * Updated the version of apache-tvm-ffi in pyproject.toml, requirements.txt, and requirements-dev.txt to ensure compatibility with the latest features and fixes.
      * Made adjustments in CUDA and HIP template files to use `const` qualifiers for global pointer parameters, enhancing code safety and clarity.
      
      * lint fix
      
      * [Enhancement] Refactor ReadWriteMarker for improved parameter handling
      
      * Updated the ReadWriteMarker class to accept a set of parameter or data variables, enhancing its ability to track written variables.
      * Introduced a new method, ResolveDataVarFromPtrArg, to resolve underlying buffer data from pointer-like arguments, improving accuracy in identifying written variables.
      * Modified the MarkReadOnlyParams function to gather handle parameters and their corresponding buffer data variables, streamlining the process of determining read-only parameters.
      * Enhanced the logic for identifying written variables to account for aliased data variables, ensuring comprehensive tracking of modifications.
      
      * lint fix
      
      * Update tma_load function to use const qualifier for global memory pointer
      
      * Changed the parameter type of gmem_ptr in the tma_load function from void* to void const* to enhance type safety and clarity in memory operations.
      * This modification ensures that the function correctly handles read-only global memory pointers, aligning with best practices in CUDA programming.
      
      * Remove commented-out code and reorder transformations in OptimizeForTarget function for clarity
      
      * Refactor buffer marking logic in annotate_read_only_params.cc to improve accuracy in identifying written variables. Update OptimizeForTarget function to reorder transformations for better clarity.

      [Tool] Provide layout visualization tool (#1353) · 924225ed
      Cunxiao Ni authored
      * Provide layout visualization tool
      
      Adds a layout visualization tool to TileLang, which helps users understand and debug the layout transformations applied during compilation.
      
      This tool visualizes the memory layout of tensors at different stages of the compilation process, allowing developers to identify potential inefficiencies and optimize their code for better performance.
      
      The visualization can be enabled via a pass config option.
      
      * format
      
      * add layout visual example
      
      * Adds vis extra with matplotlib dependency

      * fix lint
      
      * Enables configurable layout visualization formats
      
      Allows users to specify the output formats (png, pdf, svg) for layout visualization through a pass config option.
      
      This change provides more flexibility in how layout visualizations are generated, allowing users to choose the formats that best suit their needs.
      
      It also fixes a bug where layout visualization was not correctly disabled when the config option was set to "false".
      
      * Adds visual layout inference tool docs
      
      * fix lint

      * Moves layout visualization
      
      * Refactors layout visualization pass configuration
      
      Updates the layout visualization pass configuration to use boolean flag for enabling and a string for specifying formats.
      
      * Enables multiple layout visualization formats
      
      * Updates layout visualization docs
