      [Enhancement] Refactor inflight computing to support dynamic pipeline extents (#1399) · f2858fa1
      Lei Wang authored
      * [Build] Update CMake configuration for tilelang_cython_wrapper installation
      
      - Adjusted output directories for the tilelang_cython_wrapper to ensure that development builds place the extension in build/lib.
      - Updated installation paths to place the extension in tilelang/lib within the wheel, improving organization and avoiding potential conflicts with other modules.
      - Modified the internal library path exposure in env.py to prevent shadowing of common module names, enhancing compatibility and usability in user projects.
      
      * [Build] Standardize output directories for tilelang libraries
      
      - Set output directories for both tilelang and tilelang_module libraries to "${CMAKE_BINARY_DIR}/lib" for consistency in development builds.

      [Enhancement] Implement dynamic unroll factor in CUDA code generation (#1360) · 388ee7ee
      Lei Wang authored
      * [Enhancement] Implement dynamic unroll factor in CUDA code generation
      
      This commit introduces support for specifying a dynamic unroll factor in the CUDA code generation. The `unroll_factor` map is added to store unroll factors for loop variables, allowing for more flexible and optimized loop unrolling. Additionally, the `unroll` function is integrated into the loop language, enabling users to define unroll factors directly in their code. This enhancement improves performance by allowing tailored unrolling strategies based on specific loop characteristics.

      Lei Wang authored
      * [Refactor] Improve assertion handling in CodeGenCHost and ArgBinder
      
      This commit refines the assertion message generation in CodeGenCHost by optimizing the handling of equality checks and reducing buffer size for error messages. Additionally, it enhances the ArgBinder by introducing a nullable guard mechanism for assertions, allowing for more precise error handling when binding arguments. The changes improve the clarity and efficiency of assertion handling across the codebase.

      * [Refactor] Update buffer handling in copy and atomic operations
      
      * Refactored the `copy` and `atomic_add` functions to use element-wise minimum for defining copy extents, ensuring correct handling of overlapping regions.
      * Updated utility functions to create `BufferLoad` instances with explicit extents, improving memory management and clarity.
      * Removed unused imports from `atomic.py` and `copy.py` to streamline the codebase.
      * Adjusted logging in `copy.cc` to provide clearer warnings for fallback scenarios in bulk copy operations.
      
      * Remove obsolete .git_commit.txt file
      
      * Add unit test for dynamic copy extent handling in TileLang
      
      * Introduced a new test file `test_tilelang_issue_1237.py` to verify that the `T.copy` function correctly manages dynamic extents during primitive function building.
      * The test reproduces a specific issue related to dynamic slice lengths and static buffer sizes, ensuring robustness in the handling of such scenarios.
      * The test does not require execution of the kernel, as building the primitive function is sufficient to validate the fix.

      This reverts commit 828b4c1e4de76a7d11e4d4092927303fbbe00097.
      
      * Update TVM submodule and refactor atomic and copy functions
      
      * Updated the TVM submodule to a dirty state.
      * Refactored `atomic_add` and `copy` functions to pass extents explicitly to the `_to_region` helper, improving clarity and correctness in handling buffer regions.
      * Commented out the main execution call in the test example for `cast` and added a new function call to better demonstrate the example usage.
      
      * Enhance extent handling in atomic and copy functions
      
      * Introduced `legalize_pairwise_extents` utility to align and broadcast extent lists for `atomic_add` and `copy` functions, ensuring compatibility and correctness in buffer operations.
      * Updated both functions to utilize the new utility, improving clarity and robustness in handling dynamic and static extents.
      * Added comments to clarify the extent handling logic.
      
      * Enhance `legalize_pairwise_extents` function with early-exit rule
      
      * Added an early-exit condition to the `legalize_pairwise_extents` function to return original extents if the number of non-1 dimensions in both source and destination extents is equal, improving performance by avoiding unnecessary adjustments.
      * Updated the function's documentation to clarify the new behavior and maintain clarity in the extent handling logic.
      
      * lint fix

      [Enhancement] Support Layout/Fragment Reshape (#1241) · 4370309b
      Lei Wang authored
      * Update layout handling and introduce reshape functionality
      
      - Updated the `LayoutNode` class to include a new `Reshape` method, allowing for dynamic reshaping of layouts based on input shapes.
      - Enhanced the `OutputShape` method to provide better handling of cases where the analyzer cannot form an `IntervalSet`, implementing fallback mechanisms to ensure safe extents.
      - Refactored the `ReduceOpNode` to utilize `BufferRegion` for improved memory handling during reduction operations.
      - Added tests for reshaping functionality and layout transformations to ensure correctness and performance in various scenarios.

      [Refactor] Add kernel selection option for GEMM v1 in environment settings (#1200) · 8fbe1b3a
      Lei Wang authored
      * Add kernel selection option for GEMM v1 in environment settings
      
      - Introduced `TILELANG_USE_GEMM_V1` environment variable to control the selection of GEMM version.
      - Added `use_gemm_v1` method in the `Environment` class to determine if GEMM v1 should be used based on the environment variable.
      - Updated GEMM function assignment to default to v2, allowing for v1 to be forced via the new environment variable.
      
      * bug fix
      
      * Add kernel selection option for GEMM in environment settings
      
      - Introduced `TILELANG_USE_GEMM_V1` environment variable to allow users to select between GEMM v1 and v2 implementations.
      - Updated `gemm` function to default to v2 but switch to v1 if the environment variable is set to a truthy value.
      - Added a method `use_gemm_v1` in the `Environment` class to facilitate this selection based on the environment variable.
      
      * Refactor GEMM macro generator to use BufferRegion instead of Buffer
      
      - Updated `wgmma` a...
