* Add backward weight instance traits for xdl cshuffle.
To keep instance test file sizes reasonable, we start a new test_bwd_weight_instances_traits.cpp test file.
* Fix copyright notices.
* Remove (c) symbol, replace with (C).
Having UTF-8 in source caused an error with code generation.
* Refactor split-image implementation: simplify code and remove redundant variables
* Add padding debug output to split-image implementation
- Added debug prints for padding calculations in transform_conv_fwd_to_gemm.hpp
- Verified padding works correctly with all tests passing
* Fix sign comparison warning after rebase with origin/develop
- Cast blockIdX from unsigned to signed index_t for comparisons
- Integrated with new GetOutputTileIndex logic from upstream
- Updated to use amd_wave_read_first_lane instead of __builtin_amdgcn_readfirstlane
* Fix Split-N with groups bug and clean up unused parameters
- Fixed batch stride calculation to include G dimension for grouped convolutions
- When moving between batches in NHWGC/NWGC/NDHWGC layouts, need to account for all groups
- Removed unused multi-split parameters (we only support 2-way split)
- All tests now pass: G=1 with Split-N, G>1 with Split-N, G>1 without Split-N
* Implement recursive queue-based split-image detection and calculation
- Add LaunchKernelWithSplitIfNeeded() helper method in transform_conv_fwd_to_gemm.hpp
- Implement recursive binary splitting algorithm (10GB→5GB+5GB→...)
- Correctly handle odd dimensions (61→30+31)
- Calculate proper offsets for each split piece
- Update invoker to use split-image helper
Note: Split detection and calculation work correctly but kernel launching
for individual pieces requires kernel modification to handle different
spatial dimensions (unlike Split-N which uses blockIdx.z).
* WIP: Split-Image investigation - found architecture mismatch
- Split-N modifies N_ directly in transformer constructor
- Split-Image needs different approach due to varying dimensions
- Added split calculation logic for 1D and 2D convolutions
- Still facing memory issues when creating piece transformers
Key finding: Split-N uses blockIdx.z for parallel execution,
while Split-Image needs sequential execution of non-uniform pieces.
* Add 1D split-image implementation for grouped convolution (N=1 working)
Implements split-image for 1D convolution to handle large tensors that
exceed memory thresholds. This is a critical milestone with N=1 fully
working and tested.
Key Changes:
- Invoker: Add split-image logic that splits W dimension in half
- Transformer: Add SplitConvProblem helper for recursive splitting
- Calculate offsets for LEFT and RIGHT pieces
- Launch two kernels sequentially (LEFT then RIGHT)
Implementation Details:
- Binary split: divides W dimension by 2
- LEFT piece: W=0 to W/2, keeps left padding, removes right padding
- RIGHT piece: W/2 to W, removes left padding, keeps right padding
- Offset calculation accounts for stride, dilation, and padding
- Physical memory offset (no padding in memory)
Test Results (N=1):
✅ 94/94 tests passing
- Comprehensive tests: 36/36 (channels, padding, stride, dilation, filters, groups)
- Edge case tests: 31/31 (odd dimensions, extreme parameters, boundaries)
- Stress tests: 27/27 (maximum dimensions, up to 91.4 TFlops)
Known Limitations:
- Only works with N=1 (single batch)
- N>1 fails when split-image triggers (offset calculation issue with Split-N)
- Root cause: Split-N modifies N in transformer, but offset calculated in invoker
- Solution planned: Move offset calculation to transformer (next phase)
Files Modified:
- grouped_convolution_forward_invoker.hpp: Add split-image logic
- transform_conv_fwd_to_gemm.hpp: Add SplitConvProblem helper
This commit represents a stable, tested 1D split-image implementation
for N=1 cases. It's an important milestone before extending to N>1
and multi-dimensional splits.
* Add basic split-image implementation for 1D/2D/3D grouped convolution
This is a working baseline implementation that splits large spatial
dimensions to handle memory constraints.
Implementation:
- 1D: W-split for NWGC layout (36/36 tests passing)
- 2D: H-split for NHWGC layout (20/20 tests passing)
- 3D: D-split for NDHWGC layout (verified working)
Features:
- Binary split of outermost spatial dimension
- Sequential LEFT/RIGHT kernel launches
- Proper padding adjustment at split boundaries
- Offset calculation for pointer arithmetic
- Debug output for verification
Threshold: 100KB (configurable in transformer)
Known limitations:
- No safety checks for edge cases (to be added)
- Offset calculated before Split-N (incompatible with N>1, to be fixed)
- No recursive splitting for very large tensors
Next steps:
- Add safety checks (is_possible_to_split_*)
- Move offset calculation to transformer (after Split-N)
- Test with N>1 + split-image combination
* Refactor split-image to unified structure for 1D/2D/3D
Unified the three separate dimension-specific blocks into a single
common implementation with dimension-specific stride calculations.
Benefits:
- Reduced code from 636 → 348 lines (45% reduction)
- Eliminated code duplication
- Easier to maintain and extend
- Single source of truth for split logic
Implementation:
- Common: Binary split, offset calc, padding adjustment, kernel launch
- Dimension-specific: Stride calculation only
- 1D: stride = G * C
- 2D: stride = W_in * G * C
- 3D: stride = H_in * W_in * G * C
Test results (all passing):
- 1D: 36/36 tests ✅
- 2D: 20/20 tests ✅
- 3D: 28/28 tests ✅
- Total: 84/84 (100%)
All test scenarios verified:
- Varying channels, padding, stride, dilation
- Filter sizes (1x1 pointwise to 7x7)
- Multiple groups (G=1,2,4)
- Odd dimensions
- Complex combinations
* Add safety checks for split-image in all dimensions
Added is_possible_to_split safety checks to prevent crashes when
splitting is not feasible.
Safety checks verify:
1. Output dimension > 1 (can't split single element)
2. RIGHT piece starts after left padding
3. LEFT piece ends within input bounds
If checks fail, falls back to normal kernel launch.
Verified for all dimensions:
- 1D (W-split): Wo=1 case triggers fallback
- 2D (H-split): Ho=1 case triggers fallback
- 3D (D-split): Do=1 case triggers fallback
Original 84 tests still pass - they use normal configurations
that naturally satisfy safety conditions.
Safety checks protect against pathological edge cases with:
- Very small spatial dimensions
- Extreme stride/dilation combinations
- Invalid padding configurations
* Fix Split-N + Split-Image compatibility issue
Fixed critical bug where Split-N and Split-Image working together
caused ~50% incorrect results due to wrong batch stride calculation.
Problem:
- Batch stride was calculated using MODIFIED spatial dimensions
(e.g., W=50000 after split) instead of ORIGINAL dimensions (W=100000)
- Spatial offset was applied globally in invoker, not per-batch in kernel
- Each batch (blockIdx.z) got wrong memory offset
Solution:
1. Store spatial offset in kargs (don't apply to pointer in invoker)
2. Copy correct batch_stride from temp_kargs to left/right kargs
3. Apply formula in operator(): ptr = base + (batch × stride) + spatial_offset
Changes:
- grouped_convolution_forward_kernel.hpp:
* Added spatial_offset_in/out fields to KernelArgs
* Apply batch + spatial offset in operator()
- grouped_convolution_forward_invoker.hpp:
* Keep base pointer, store spatial offset in kargs
* Copy batch_stride from temp_kargs (has original dimensions)
- transform_conv_fwd_to_gemm.hpp:
* Add debug output for split-image calculation
Results:
- N=1 tests: 84/84 passing (100%)
- N>1 tests: Now all passing (previously ~50% errors)
- Tested: 1D, 2D, 3D with N=1,2,4,8,16,20
* Implement unified threshold for Split-N and Split-Image
This commit consolidates threshold management for both Split-N and
Split-Image operations into a single source of truth, eliminating
code duplication and fixing offset calculation issues.
Key Changes:
============
1. Transformer (transform_conv_fwd_to_gemm.hpp):
- Moved TwoGB constant to public section for unified access
- CalculateSplitImage() now takes no parameters
- Uses internal threshold: TwoGB / sizeof(CDataType)
- Calculates offsets using N_ (after Split-N) for correctness
2. Kernel (grouped_convolution_forward_kernel.hpp):
- GetSplitImageInfo() simplified to take no parameters
- Forwards to transformer's CalculateSplitImage()
- Clean interface with unified threshold internally
3. Invoker (grouped_convolution_forward_invoker.hpp):
- Removed redundant threshold calculation
- Simplified to call kargs.GetSplitImageInfo() with no params
- Clean early-return pattern (no unnecessary else blocks)
- Removed duplicate/dead code paths
Benefits:
=========
- Single source of truth: TwoGB defined once in transformer
- No parameter passing for threshold between components
- Correct offset calculation using N_ (post-Split-N)
- Cleaner code with no duplication
- All tests passing: 1D/2D/3D with various N values
Testing:
========
- Split-Image only (N=1, large spatial): PASS
- Split-N only (N>1, small spatial): PASS
- Both splits active (N>1, large spatial): PASS
- No splits (N=1, small spatial): PASS
- CPU verification correct for all scenarios
* Comment out outdated split-image code (SplitConvProblem/LaunchKernelWithSplitIfNeeded)
The old recursive queue-based implementation has been replaced by the
new CalculateSplitImage() method which is simpler and correctly handles
Split-N + Split-Image interaction.
Changes:
- Wrapped lines 381-1078 in #if 0...#endif
- Old methods: SplitConvProblem() and LaunchKernelWithSplitIfNeeded()
- Preserved for reference but disabled from compilation
- No functional changes - all tests still pass
The new implementation (CalculateSplitImage at line ~2163) provides:
- Correct offset calculation using N_ (after Split-N)
- Simpler binary split logic
- Better integration with unified threshold approach
* Implement recursive split-image with depth limit (MAX_DEPTH=10)
Changes:
- Add depth tracking to SplitPiece struct
- Implement two stopping conditions:
1. Piece size below threshold (optimal case)
2. Depth >= MAX_DEPTH (prevents infinite recursion)
- Remove MAX_PIECES limit in favor of depth-based control
- Support up to 2^10 = 1024 pieces with depth 10
This allows handling extreme tensor sizes while ensuring termination.
Pieces larger than threshold will still launch correctly if depth limit reached.
Tested with H=100 (4 levels), H=2000 (6 levels), H=4000 (9 levels) - all pass CPU verification.
* Summary of recursive split-image implementation:
- Recursive queue-based splitting with depth limit (MAX_DEPTH=10, up to 1024 pieces)
- Two stopping conditions: size below threshold OR max depth reached
- Cumulative offset tracking through all recursion levels
- LEFT piece inherits parent offset, RIGHT accumulates (parent + local)
- Per-batch spatial offset application in kernel operator()
- Batch stride uses original dimensions (before split)
- Works with Split-N: split-N first, then recursive split-image
- Handles odd dimensions, padding, stride, dilation correctly
- All 1D/2D/3D tests pass with CPU verification
* Add comment explaining MAX_DEPTH capacity for 2GB threshold
* Refactor: move recursive split-image logic to transformer
- Move LaunchWithRecursiveSplit() from invoker to transform_conv_fwd_to_gemm.hpp
- Simplify invoker from ~250 lines to ~140 lines (removed 110 lines of inline logic)
- Encapsulate SplitPiece struct and BFS splitting algorithm in transformer
- Remove unused includes (queue, vector) from invoker
- Add documentation comment for AreDescriptorsSmallerThan2GB()
- Improve code organization and reusability
- No performance overhead (static template function, compiler inlines)
- All tests passing with 2GB production threshold
* Apply clang-format-18 formatting
- Format invoker and transformer files with clang-format-18
- Fix brace placement and alignment
- No functional changes
* Fix clang-format-18 issues in forward kernel
- Remove extra blank lines
- Fix line wrapping for template calls

* Split-Image implementation with temporary fixed divider
- Implemented spatial dimension splitting (Split-Image) for large tensors
- Added piece-based coordinate transformation for 1D/2D/3D convolutions
- Integrated Split-N (batch splitting) with automatic threshold detection
- Fixed M dimension calculation to include batch: M = N × spatial_size
- Added spatial offset support in kernel arguments
- Verified 20/20 test cases passing for Split-Image alone
- Known issue: Split-N + Split-Image combination needs coordinate fix
Implementation Details:
- Split factors: 4 (1D), 4×4 (2D), 4×4×4 (3D) - temporary fixed values
- Batch strides properly calculated for NWGC/NHWGC/NDHWGC layouts
- Piece descriptors track spatial boundaries and block ranges
- No performance overhead for N=1 cases
* Fix 1D split-image padding issue with per-piece dimensions
- Store actual size per piece to handle non-uniform splits
- Remove dead code from transform utils
* Fix 2D/3D split-image with independent split factors per dimension
Problem: Single split factor caused non-uniform pieces when dimensions
didn't divide evenly. Result: 18/25 (72%) 2D padding combinations failed.
Solution: Independent split factor selection for W, H, D dimensions.
Each dimension gets optimal factor based on its own size.
Test Results:
- 1D: 42/42 pass (100%)
- 2D: 25/25 pass (100%)
- Total: 67/67 combinations verified
* Remove unused split-image struct fields
Cleanup of split-image implementation:
- Removed unused piece_d, piece_h, piece_w fields from SplitImageInfo struct
- These fields were declared but never used in the kernel
- Per-piece dimensions are already stored in pieces[] array
- Reduces struct size and improves code clarity
Tested: 1D/2D/3D convolutions with split-image, padding, stride all pass
* Refactor split-image invoker code for improved readability

- Move calculate_spatial_piece to library utils
- Add layout validation (NWGC, NHWGC, NDHWGC only)
- Fix hierarchical splitting to respect piece limits
- Add proper documentation and formatting
* Change split-image from runtime to compile-time branching
Response to @bartekxk review comment:
Convert 'if(kargs.num_spatial_pieces > 1)' to 'if constexpr(EnableSplitImage)'
Changes:
- Add EnableSplitImage template parameter to kernel
- Change runtime if to compile-time if constexpr
- Update invoker to instantiate kernel variants with true/false
Benefits:
- Eliminates runtime branching in GPU kernel
- Dead code elimination (each variant is smaller)
- Better compiler optimization

* Refactor instance_traits_util and add unit tests tests
* Address reviewer comments.
Just adds some TODOs to indicate deprecated layouts in our reflection. Our strategy is to leave the reflection code broad (covering deprecated features), but keep the builder concepts narrow. Once we've removed deprecated features from all instances, we can remove them from reflection.
Also add a comment to the cmake to explain the unit test target test_conv_builder.
* Addressed more reviewer comments.
* Remove duplicate PassThrough::name
Accidentally added this field to the end of the struct, too. The `name` field should be a the start of the struct for consistency.
* [CK_BILDER] Add compile-time reflection for a convolution instance
Introduce InstanceTraits template metaprogramming framework to enable runtime introspection of device kernel template parameters without requiring implementation knowledge. This reflection system extracts configuration details (block sizes, data types, layouts, tuning parameters) directly from kernel specializations through template
pattern matching. In particular, the GetInstanceString method returns a string that uniquely idenitfies the kernel, by explicitly serializing all template paramter values.
This provides critical functionality for MIOpen integration, since the existing GetTypeString method is ambiguous, and only captures some of the template paramters.
The implementation uses a two-level design: a primary InstanceTraits template declaration in instance_traits.hpp serves as the interface, while kernel-specific specializations (e.g., for DeviceGroupedConvFwdMultipleABD_Xdl_CShuffle_V3) provide the actual extraction logic. This separation allows the reflection system to scale to additional kernel types without modifying the core interface.
Key architectural decisions:
- Forward-declare device kernels in instance_traits.hpp to avoid circular dependencies, since device implementation headers will include the reflection headers
- Use compile-time constants and type aliases to expose kernel parameters, enabling zero-overhead introspection
- Provide a templated instance_string() function that generates human-readable kernel configuration strings by serializing all template parameters in order, useful for debugging and kernel identification
- Guard reflection integration with preprocessor definition CK_EXPERIMENTAL_BUILDER to keep it opt-in until the API stabilizes
- Add GetInstanceString() virtual method to BaseOperator, allowing runtime polymorphic access to compile-time kernel information
This infrastructure also enables upcoming higher-level semantic reflection abstractions (like ConvTraits) to query kernel configurations programmatically.
Includes unit tests validating both the trait extraction accuracy and the string generation format.

* Fixed compilation failure.
* Modified some code as per gemm_universal_examples
* Fixed the gemm specialization error
* Fixed the build errors.
* Fix strides of a/b_thread_desc
The descriptors are larger than needed (even though the compiler don't alloc registers for unused values).
* Load in M/NRepeat dims with thread copy's slice instead of a loop
* Clone BlockwiseGemmXdlops_pipeline_v1 for WMMA implementation
* Implement Intrawave and Interwave variants of pipeline v1

* Add a workaround for fp8/bf8->f32 packed conversion issue
* Add instances for Interwave and Intrawave v1
* Enable profiling of mixed precision with f8 and int4 on WMMA
* Fix segfault in profiler when B is pk_i4_t
b_device_buf's size in bytes is larger than b_k_n_permute so b_device_buf.ToDevice reads out-of-bounds.
* Remove instances that are too slow (mostly because of register spilling)
* Add missing add_device_gemm_wmma_universal_f8_f8_bf16 declarations
* Add test case for bf16_i4
* Add missing Regular tests
* Add test_gemm_universal_xdl/wmma_fp16 to REGRESSION_TESTS
They take more than 30 seconds
* Fix a bug that fp16_i4 validation passes only with PermuteB
A permutation required by conversion from pk_i4_t to half_t does not
depend on PermuteB, they can be used independently.
* Use PermuteB with f16_i4 in most instances (as xdl)
Some instances use PermuteB = false for checking correctness.
See also the previous commit.
* Fix cache flushing for pk_i4
* Add mixed precision examples
* Disable all tests and instances with f8 on gfx11
Even though f8_f16 and f16_f8 don't require f8 WMMA instructions,
gfx11 still lacks hardware instructions for fast f8->f32 conversion.
* Add FP16 KM_NK and KM_KN test suites for XDL
These tests were added to common .inc for better testing of WMMA instances

* Prepare gemma_add tests for adding wmma
* Add gemm_add_fastgelu instances and test
* Add a special wrapper to use DeviceGemmMultipleD_Wmma_CShuffleV3 with old API

* Create new copies of existing device struct and gridwise struct for batched_gemm_softmax_gemm and disable the softmax part. Still based on old wmma pipelines. Also copy the example and remove the softmax part from the reference calculation. Works and results match reference except for tiny float errors in problem 2.
* Turn DeviceBatchedGemmGemm_Wmma_CShuffleV3 into a proper DeviceBatchedGemmGemm derived class, with the right argument and invoker functions. Update example to use new definitions.
* Remove unused cross-attention and self-attention kernels, arguments, and invokers. Also remove other unused Argument types.
* Remove masking related code, test unusual sizes in example.
* Remove remaining softmax related code from GridwiseBatchedGemmGemm_wmma_cshuffle_v3 and example.
* Remove code related to numDims, bias, and TensorSpec from Device struct and example.
* Add layout template parameters to device struct
* Move (NPerBlock, LTilePerBlock) device struct template arguments up by two places to match XDL template argument ordering.
* Merge accumulation data types into one type to match XDL device struct.
* Remove NPerWmma template parameter from device struct and just set it equal to LPerWmma. Now device struct template params exactly match those for XDL batched gemm gemm.
* Add support for RCCR layout and test this in example
* Add batched_gemm_gemm_wmma to instance library + profiler, and add gtest just like for xdl.
* Add RCCR instance and additional RCRR instance to library.
* Remove unused permute and alpha related code. Time all tests. Fix B1 strides in argument verification.
* Remove references to G0, G1 in favor of batch, reduce dimensionality of length and stride arrays.
* Managed to replace old wmma gridwise pipeline and blockwise struct with new wmma blockwise pipeline. Some cleanup required but all tests pass.
* Make TransposeC a proper template parameter that gets passed all the way from BlockGemmPipeline_Selector to WmmaGemm so we can use the correct settings for bacthed gemm gemm as well as regular gemm. Gemm universal tests now pass again.
* Replace old LoopSched and PipelineVer params with BlockwiseGemm pipeline equivalents, and use these in instance factory. The v3 pipeline does not work yet, but v1 works for intrawave and interwave.
* Adapt the A wave descriptor to deal with RDNA4 wmma. This fixes batched gemm gemm functionality on RDNA4.
* Fixed two aspects of the v3 pipeline that were incorrect: First of all the blockwise copy operator was invoked once too many in all cases (RunRead and move window), which broke batched gemm gemm when the blockwise pipeline was used multiple times. Furthermore we should be using the mainloop (hotloop) for num_k_loop >=2 instead of num_k_loop >=3. Now we can use support any K dimension.
* Remove num prefetch parameter from gridwise struct since we don't use it and it doesn't do anything,
* Remove unused non-lds paths.
* Test and update the IsSupportedArgument() and CheckValidity() functions for all layouts + padding modes and various problem sizes.
* Add a lot of instances to the profiler with various blocksizes and pipelines, all verified.
* Add support for BF16: instance library, tests, and examples.
* Add examples for int8 and fp8, had to add type_convert_sp template specializations for the latter.
* Template the library instance lists and add default padding instances.
* Move memory calculations from the kernel to the Argument contructor. Also actually parse and use the user-provided batch strides.
* Actually parse and use user-provided regular strides.
* More refactor: remove references to multiple dims per dims, and g0 / g1. Also move xdl specific test utils out of generic test util header.
* Small post-rebase-on-develop fix due to bscale-related pipeline changes. All tests rerun + tested bscale and regular gemm.
* Introduce the correct GetCThreadDescriptor function in the blockwise gemm pipelines for the TransposeC=true case. It turns out to be identical for our batched gemm gemm (gemm0) usecases, but could theoretically be different for wmma_gemm instances with smaller-than-4-byte output data size.
* Remove unused NumPrefetch template parameter, we don't need to match the XDL template params one-to-one.
* Implement proper TailNum and HasMainLoop template parameters for the v3 pipeline. Now the Run() function knows at compile time whether there are 1, 2, or more loops in total, and adds or removes sections accordingly. It still uses the blockwise copy operators the correct amount of times.
* Add print lambda with env check and file and func to device and gridwise level compatibility error messages. Also respect compatibility in example script.
* RDNA3 does not support fp8
Update Blockwise and Gridwise files to support both wave32 & wave64.
1. Calculate WaveSize from template parameter, instead of hard code it to 64, some "64" is also replace with WaveSize
2. Move BN0Shuffled and BK0Shuffled to device side. we can't get correct mfma inst info in host side.
3. Update b_thread_offset_n and b_thread_offset_k in gridwise_gemm_xdl_cshuffle_v3_b_scale.hpp for gfx11. in gfx11, input data is duplicated for each 16 threads, it is different with all of others.
4. Modify a1_threadwise_copy in gridwise_batched_*gemm*gemm for gfx11. for gfx11, we need duplicate input and swizzle A if transposeC isn't enabled.
