[CK Tile] Eight Waves pipeline GEMM

## Motivation

Eight waves pipeline was added for ABQuant. The goal of this PR is to
enable it also for GEMM

## Technical Details

Summary:
 - Block:
- Create block struct for GEMM using eight warps specific distribution
encodings
   - Use this block struct in ABQuant for encodings
 - Pipeline:
- Create impl pipeline for eight waves which can be used by GEMM and
ABQuant as base (and for AQuant and BQuant in the future)
- Create eight waves pipeline for GEMM (this can not be easily
integrated in the existing async pipeline)
 - Pipeline policy:
- Extract GEMM specific parts in the ABQuant policy to define GEMM
policy (then ABQuant use it as base and add Quant specific methods)
- Minor: naming was inconsistent between warp/wave, everything is now
referred to as eight waves

So overall we have:
- block struct directly used by GEMM -> ABQuant derived struct to
implement operator
- Impl base pipeline with general implementation -> GEMM and ABQuant
pipelines use it to avoid code duplication but still define their own
pipelines
- pipeline policy struct directly used by GEMM -> ABQuant derived policy
struct for Quant specific parts

## Test Plan

Added new tests for GEMM pipeline:
`test_ck_tile_gemm_pipeline_comp_async_eight_waves` (only gfx950
supports it).

Note: K padding test is disabled for this pipeline because it's not
implemented yet

[CK TILE] Skip work if any of Grouped GEMM groups M/N/K are
 zero. (#5050)

## Motivation

It's common in MoE workloads that some experts receive zero tokens,
which would result in some of the dimensions equal to zero. Currently we
handle such case only for non-persistent kernels where we have all GEMMs
information beforehand on host - we validate this during creation of
kernel arguments. However for the "dynamic" input path (persistent
kernel) this information is not available before kernel launch. Thus we
have to validate this during kernel execution. The goal is to add this
validation.

## Technical Details

Skip work if any of Grouped GEMM groups M/N/K are zero for persistent
kernel path.

## Test Plan

Add unit-tests which cover "dynamic" inputs with zero dims for
persistent kernel execution path.

## Test Result

All tests pass.

ck_tile: add gtest unit tests for MX flatmm (gfx950)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

- Add correctness unit tests for the MX-format flatmm kernel
(`example/ck_tile/18_flatmm/mxgemm`) under `test/ck_tile/flatmm/`
- Tests cover all five dtype combinations: FP4×FP4, FP8×FP8, FP6×FP6,
FP8×FP4, FP4×FP8
- Tests cover all four kernel dispatch paths (the `has_hot_loop` ×
`tail_num` product):
  - `has_hot_loop=false, tail=ODD` (K=256, num_loop=1)
  - `has_hot_loop=false, tail=EVEN` (K=512, num_loop=2)
  - `has_hot_loop=true, tail=ODD` (K=768, num_loop=3)
  - `has_hot_loop=true, tail=EVEN` (K=1024, num_loop=4)
- Remove unsupported `-split_k` CLI option from
`tile_example_mx_flatmm`; the pre-shuffled B layout is incompatible with
K-splitting and the option silently produced wrong results

## Changes

**New files (`test/ck_tile/flatmm/`):**
- `CMakeLists.txt` — builds 40 kernel instances as a shared OBJECT
library, links into 5 per-dtype test executables; forwards
`-DCK_TILE_USE_OCP_FP8` when `CK_USE_OCP_FP8` is ON
- `test_mx_flatmm_base.hpp` — base test fixture with
`run_test_with_validation(M, N, K, kbatch=1)`
- `test_mx_flatmm_fixtures.hpp` — concrete `TestMXFlatmm` typed test
class and type aliases
- `test_mx_flatmm_fp{4fp4,8fp8,6fp6,8fp4,4fp8}.cpp` — per-dtype
`TYPED_TEST_SUITE` files

**Modified files:**
- `example/ck_tile/18_flatmm/mxgemm/mx_flatmm_arch_traits.hpp` — moved
`preShuffleWeight` here (was in `mx_flatmm.cpp`) so it is includeable by
both the example and the tests
- `example/ck_tile/18_flatmm/mxgemm/mx_flatmm.cpp` / `run_mx_flatmm.inc`
— removed `-split_k` CLI arg, hardcoded `k_batch=1`, fixed `k_split`
formula, updated call sites after `preShuffleWeight` move
- `test/ck_tile/CMakeLists.txt` — added `add_subdirectory(flatmm)`

c1f2d8166d [rocm-libraries] ROCm/rocm-libraries#5242 (commit ea9a066)
[CK_TILE] Add the GEMM Memory pipeline to Stream-K tests
 (#5242)

## Motivation

We want to extend our Stream-K coverage to include other GEMM pipeline
since our current tests only test the CompV3 pipeline.

## Technical Details

All Stream-K unit tests currently only tests one pipeline: CompV3. These
changes extend the test support to also test the Memory pipeline. Future
work will add support for additional GEMM pipelines.

The major changes are as follows:
- **Remove of fp8 and bf8 extended tests for gfx90a**: gfx90a does not
have native support for fp8 and bf8 and emulate the behavior with fp32
mfma instruction sizes. We've observed extremely long compile times for
fp8 and bf8 on gfx90a (exceeding 15 minutes), hence we've opted to
disable these tests.
- **Add the memory pipeline to the Stream-K tile engine tests**: Now our
smoke tests covers compv3 and memory pipelines.
- **Add the memory pipeline to the Stream-K extended tests**: These
changes modify the test kernel types to include the appropriate
pipeline. Each pipeline is contained within a separate kernel type to
help avoid large increases in build time.

## Test Plan

- Ran existing and added tests on all architectures.

## Test Result

- All local tests pass.

[CK_TILE] Optimize ck_tile::sequence to reduce template
 instantiation depth [2A] (#5028)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

### Rationale
`ck_tile::sequence` is the most fundamental metaprogramming type in
ck_tile — it underpins
tensor dimensions, strides, loop bounds, and index calculations. Six of
its metafunctions
use recursive template instantiation, producing O(N) to O(N²)
intermediate types that
the compiler must process. When these are used inside deeply nested GEMM
pipelines with
large dimension counts, the cumulative instantiation overhead becomes a
significant
contributor to frontend compile time.

Measurements on `test_gemm_pipeline_compv6` show 84,288
`InstantiateFunction` calls in
the frontend alone. Reducing template instantiation depth in these core
utilities has a
multiplicative effect because they are called from hundreds of sites.

### What changed

| Metafunction | Before | After |
|---|---|---|
| `sequence::modify` | O(N) recursive split/merge | O(1) pack expansion
|
| `sequence_gen` | O(log N) recursive binary split | O(1) via
`__make_integer_seq` |
| `uniform_sequence_gen` | Delegates to `sequence_gen` | O(1) via
`__make_integer_seq` |
| `sequence_reverse_inclusive_scan` | O(N) recursive | O(1) constexpr
for-loop + pack expansion |
| `sequence_inclusive_scan` | Computed via reverse + flip | O(1)
constexpr for-loop (unified impl) |
| `sequence_exclusive_scan` | O(N) recursive merge chain | O(1)
constexpr for-loop + pack expansion |
| `sequence_map_inverse` | O(N²) recursive modify calls | O(1) constexpr
for-loop + pack expansion |

Supporting changes:
- Portable `__type_pack_element` fallback with `__has_builtin` guard
(hipRTC-safe, no `<tuple>` dependency)
- Renamed reserved `__integer_sequence` to `integer_sequence_wrapper`
- Adopted `static_array` from develop (PR #4355) for constexpr
computation
- Unified forward and reverse inclusive scan into a single
`sequence_inclusive_scan_impl` with `bool Reverse` template parameter
- Added `sequence_inclusive_scan` struct (new public API for forward
scan direction)
- Replaced recursive `sequence_exclusive_scan` (3 template
specializations) with `sequence_exclusive_scan_impl` using the same
constexpr for-loop pattern as inclusive scan
- Rewired `exclusive_scan_sequence` and `prefix_sum_sequence` to use new
impl
- Added `CK_TILE_HOST_DEVICE` to `exclusive_scan_sequence` and
`prefix_sum_sequence` to match sibling scan function annotations

### Technical debt and housekeeping
- Unified all `namespace impl` to `namespace detail` across sequence.hpp
for consistency
- Removed dead comment block (orphaned `integer_sequence` alternative)
- Added defensive `static_assert(sizeof...(Is) > 0)` in
`sequence_map_inverse::build_inverse`
- Converted all multi-line Doxygen blocks from `///` to `/** */` per
style guide
- Corrected `constexpr static` to `static constexpr` keyword ordering in
`static_array`
- Added blank line between `#pragma once` and first `#include` in
`static_array.hpp`
- Trimmed redundant 4-line comment on `sequence_gen_helper` to a
one-liner
- Moved `sequence_gen` Doxygen comment below `namespace detail` block so
it directly precedes the struct it documents
- Added Doxygen `@brief`/`@tparam`/`@pre` documentation for
`sequence_gen` and `sequence_map_inverse` public APIs
- Added `@brief` documentation to `static_array` explaining relationship
to `ck_tile::array`
- Added scope comment at `namespace detail` openings

**Note:** `private:`/`public:` access modifier indentation is enforced
at 4 spaces by
`.clang-format`. The style guide calls for left-alignment, but the
formatter overrides
this. Requires a `.clang-format` config change to resolve — not
addressable in code.

### `static_array` hardening (from develop's PR #4355)
- Added zero-length array guard (`T elems[N > 0 ? N : 1]`)
- Added `CK_TILE_HOST_DEVICE` annotations to `operator[]` and `size()`
- Added `#include "ck_tile/core/config.hpp"` (IWYU for
`CK_TILE_HOST_DEVICE`)

### Value
Combined with the `static_ford` changes, measured impact on
`test_gemm_pipeline_compv6`:
- **Frontend: -28.9%** (InstantiateFunction: 84,288 → 69,439)
- **Backend: -13.1%** (CodeGen Functions: 3,170 → 2,203)
- **Wall-clock: -16.3%** (611.6s → 512.2s)

### Files changed (4)
- `sequence.hpp`: Metafunction optimizations, namespace unification,
documentation, style fixes
- `static_array.hpp`: Zero-length guard, `CK_TILE_HOST_DEVICE`,
documentation, style fixes
- `test_sequence.cpp`: 50 unit tests with runtime `EXPECT_EQ` assertions
(new file)
- `CMakeLists.txt`: Register new test target

## Test plan
- [x] 50 runtime unit tests covering all optimized and pre-existing
sequence APIs
- [x] Edge cases: empty sequences, single-element, larger sizes (N=8),
negative values, non-trivial init values
- [x] Both functor signatures tested (`operator()(index_t)` and
`operator()(number<I>)`)
- [x] Both scan reducers (`plus`, `multiplies`) with forward, reverse,
inclusive, and exclusive directions
- [x] Exclusive scan: sum, product, single, empty, non-zero init
- [x] Prefix sum: N+1 output verification, single, empty
- [x] Permutation round-trip verification for `sequence_map_inverse`
- [x] Full sequence public API coverage: modify, gen, uniform_gen, scans
(inclusive, exclusive, prefix sum), map_inverse, make_index_sequence,
size/sum/product, push/pop, reverse, extract, merge, arithmetic
operators, equality, transform
- [x] Portable `__type_pack_element` fallback tested implicitly (same
`at_index_t` interface)

2312eef6c3 [rocm-libraries] ROCm/rocm-libraries#4368 (commit 17f7dfc)
[CK_TILE][FMHA] Support microscaling (mxfp8 and mxfp4) on
 gfx950 (#4368)

## Motivation

Microscaling types (mxfp8 and mxfp4) for fwd qr pipeline

## Technical Details

The microscaling is used when quant scale mode is
`BlockAttentionQuantScaleEnum::MX` and `Q/K/P/VDataType` are
fp8/bf8/fp4.

Supported features:
* only "qr" pipeline is implemented
* hdim 128 and 256 (smaller hdim are not possible due to restrictions of
"qr" pipeline, but they can be computed using instances with padding)
 * both 32x32x64 and 16x16x128 scale MFMAs are supported
 * Q and K scales are applied in hdim, V scales - in seqlen dimension
 * column-major V only
 * batch and group mode
 * bias, Alibi (tested but no instances by default, just like fp8)
 * masking etc.

Aiter PR with new API args: https://github.com/ROCm/aiter/pull/2008

## Test Plan

```
ninja test_ck_tile_fmha_fwd_mxfp8 && bin/test_ck_tile_fmha_fwd_mxfp8
ninja test_ck_tile_fmha_fwd_mxfp4 && bin/test_ck_tile_fmha_fwd_mxfp4
```

## Test Result

The tests must pass.

26d29374e5 [rocm-libraries] ROCm/rocm-libraries#5213 (commit 9f7e62c)
[CK] Fix warp tile combination selection in absence of a GPU
 (#5213)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Motivation

The `get_gpu_name_by_id()` function in
`gemm_streamk_validation_utils.py` relies on `rocminfo` to detect the
GPU architecture at runtime. However, __`rocminfo` fails in CI/build
environments__ where:

- No physical GPU is present
- ROCm tools are not installed
- The build is running in a container without GPU access

In any of these environments, the problem manifests itself in incorrect
kernel validation and will generate template instantiations that do not
exist:

```

## Technical Details

### Changes Made:

#### 1. __gemm_streamk_validation_utils.py__

- Added module-level storage: `_configured_gpu_targets`

- Added `set_gpu_targets(targets: List[str])` to configure fallback GPU
targets

- Added `get_configured_gpu_targets() -> List[str]` to retrieve
configured targets

- Enhanced `get_gpu_name_by_id()` to:

  - First try `rocminfo` (existing behavior)
  - If `rocminfo` fails, fall back to first configured GPU target
  - Extract base gfx name (e.g., "gfx90a" from "gfx90a:xnack+")
  - Log debug messages when using fallback

#### 2. __gemm_streamk_instance_builder.py__

- Added `--gpu_targets` command-line argument
- Automatically calls `set_gpu_targets()` when `--gpu_targets` is
provided
- Parses semicolon-separated GPU target list from CMake

#### 3. __test/ck_tile/gemm_streamk_tile_engine/CMakeLists.txt__

- Modified both `--list_kernels` and `--gen_single` invocations to pass
`--gpu_targets "${SUPPORTED_GPU_TARGETS}"`
- GPU targets are now automatically wired from CMake to Python scripts

### How It Works:

1. __CMake Configuration__: `SUPPORTED_GPU_TARGETS` is determined from
`GPU_TARGETS` or defaults
2. __CMake → Python__: CMake passes targets via `--gpu_targets` argument
to Python scripts
3. __Python Configuration__: Scripts call `set_gpu_targets()` to
configure the fallback
4. __Fallback Mechanism__: When `rocminfo` fails, `get_gpu_name_by_id()`
uses the first configured target
5. __Target Parsing__: Extracts clean gfx name (e.g., "gfx90a" from
"gfx90a:xnack+")

## Test Plan

Confirm that only the appropriate kernels are selected and that CI
passes.

## Test Result

1. Waiting on CI
2. Compilation succeeded locally and the kernel list does not contain
the 16x16x8 kernel for gfx942 anymore:

[CK] Streamk tile engine test not setting a reasonable
 CU_COUNT default when the query fails (#5165)

## Motivation

The following error was coming up when compiling on Windows when the
generate_configs.py file tries to query the GPU for the number of CU's:

```

[composable_kernel configure FAILED WITH CODE 1 in 41 seconds]
ninja: build stopped: subcommand failed.
```

## Technical Details

There was one major problem in the following code and two changes were
made:

```
        execute_process(
            COMMAND ${CPP_EXE_PATH}
            OUTPUT_STRIP_TRAILING_WHITESPACE
            ERROR_VARIABLE standard_error
            RESULT_VARIABLE queried_cu_count
        )

        if (standard_error)
            message(STATUS "Error information from attempting to query HIP device and properties:\n"
                            "${standard_error}")
        endif()
```

1. RESULT_VARIABLE does not capture the IO output of the executable, but
rather the exit code. You can see from the error output here that it was
trying to cast "Exit code 0xc0000135\n" to an integer. I fixed this by
changing RESULT_VARIABLE to OUTPUT_VARIABLE.

```
[composable_kernel configure] ValueError: invalid literal for int() with base 10: 'Exit code 0xc0000135\n'
```

Note that this also gives us the reason that the query failed: Exit code
0xc0000135, which needs to be addressed in a separate issue: "Exit code
0xc0000135, also seen as -1073741515, is a Windows error indicating that
an application failed to start because a required Dynamic Link Library
(DLL) file or a system component like the .NET Framework is missing or
corrupted"

It's likely the executable that is created from this code can't find the
hip dll, or something similar:

```
        set(CPP_FILE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cu_count.cpp)
        set(CPP_EXE_PATH ${CMAKE_CURRENT_BINARY_DIR}/cu_count)

        execute_process(
            COMMAND ${CMAKE_HIP_COMPILER} -x hip ${CPP_FILE_PATH} -o ${CPP_EXE_PATH}
            RESULT_VARIABLE compile_result
        )
```

2. For clarity and consistency purposes, I changed the check afterwards
to explicitly look for a non-zero exit code. This matches previous
checks in the cmake file. I also added improved error checking when the
query for the cu count fails.

## Test Plan

Ensure it compiles locally and existing CI isn't impacted.

## Test Result

Waiting on CI.

[CK_TILE] Fix MMA layout test to match amdgcn_mma OpFamily
 parameter (#5222)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

- PR #4837 added `MmaOpFamily OpFamily_` as a new template parameter to
`amdgcn_mma` and `MmaDefaultSelector`, but the MMA layout test (PR
#4495) was not updated to include it
- Add the missing `OpFamily_` parameter to all three `RegisterMapTraits`
partial specializations (gfx9, gfx11, gfx12) and all
`MmaDefaultSelector` usages
- Fixes build failure: `template argument for non-type template
parameter must be an expression`

## Test plan

- [x] Verified test compiles cleanly with ROCm 7.1.1 clang++ targeting
gfx90a
- [x] `test_amdgcn_mma_layout` gfx90a (MFMA): PASSED
- [x] `test_amdgcn_mma_layout` gfx1201 (WMMA): SKIPPED (no device)
- [x] `test_amdgcn_mma_layout` gfx1100 (WMMA): SKIPPED (no device)
- [x] CI validation on all GPU targets

b80e41f3bc [rocm-libraries] ROCm/rocm-libraries#4495 (commit 5664eb0)
Adding layout test for amdgcn_mma structs

## Motivation

Currently, the test suite for `amdgcn_mma` focuses on the design (e.g.
choosing the correct specialization based on SFINAE) and a single live
test that checks if selected MmaOp runs. This PR adds a simplified GEMM
test kernel that checks the exact layout of the selected MmaOp.

## Technical Details

The test in `test_amdgcn_mma_layout.cpp` launches MxKxN test cases (one
per block), where each case:
1. Constructs A and B tensors on a device with a single 1 at A(m,k) and
B(k,n) (rest is all 0s)
  2. Executes the MMA intrinsic.
  3.  Checks if C has the "1" on the excpeted position.

For the MMA instrinsic, it pulls a Mma op from amdgcn_mma specialization
based on a given input (tile dimension, data types).

Note 1: As a helper, in `test_amdgcn_mma_layout_util.hpp` we add
register map for a given amdgcn_mma specialization. Register mapping is
currently based on the `tile_distribution_encoding`.

Note 2: Everything is added to the test suite, no additions to the
actual `amdgcn_mma` structs. All the extra information that is needed,
but not yet provided by `amdgcn_mma` structs, is added as a boilerplate
to the header. TODO: Rebase this PR on top of the `amdgcn_mma` refactor
or clean it up after merge.

## Test Plan

This PR solely adds a new test to the existing code.

## Test Result

Tests pass.

03ce21ddcb [rocm-libraries] ROCm/rocm-libraries#4837 (commit 6316035)
[CK TILE] Unification of sparse MFMA/WMMA policy structs
 (#4837)

## Motivation

The existing unification work supports DENSE intrinsics. In this PR we
enable support for SPARSE as well as SCALE intrinsics and add an example
SPARSE implementation.

## Technical Details

Mostly trivial changes. One framework change is that the desired
`MmaOpFamily` is passed to the `MmaDefaultSelector`. As my relevant
commit explains, we do not support a fallback family at the moment, but
it is something we can consider.

## Test Plan

Added a new test for the relevant sparse specializations.

## Test Result

Test should pass.

[CK_TILE][GEMM] Fix eightwarp error & Add eightwarp unit test
 (#4834)

## Motivation

The primary goal of this PR is to fix a critical issue in the EightWarps
implementation within ck_tile. Additionally, unit tests were added to
ensure that CI can detect errors.

## Test Plan

ninja test_tile_gemm_quant_abquant_eightwarps
./bin/test_tile_gemm_quant_abquant_eightwarps

## Test Result

All EightWarps related test cases in TestCkTileGemmABQuant completed
successfully without linker errors or validation mismatches.

2a16d53cce [rocm-libraries] ROCm/rocm-libraries#5045 (commit 64a5502)
[CK] Address a bunch of errors associated with targeting
 gfx1200 on Windows (#5045)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Motivation

Still addressing errors that are blocking the merge of TheRock PR:
https://github.com/ROCm/TheRock/actions/runs/22545831304/job/65308264096?pr=3382

## Technical Details

1. There are multiple fmha python scripts that are writing native paths
which are confusing cmake. I addressed one of these in an earlier PR
https://github.com/ROCm/rocm-libraries/pull/4812 and now I'm addressing
more that are exposed with gfx1200 target:

```
[composable_kernel configure] CMake Error at example/ck_tile/50_sparse_attn/CMakeLists.txt:61 (add_library):

[composable_kernel configure]
[composable_kernel configure]   Invalid character escape '\b'.
```

2. In the following compiler error we see gemm_prec_str<ADataType,
BDataType> being passed as a function to concat(...), instead of being
evaluated with the parenthesis operator(), i.e.,
gemm_prec_str<ADataType, BDataType>(). There are multiples instances of
this, I wonder what non-msvc compilers do here:

```

```

There are plenty of other places where we use gemm_prec_str with the
operator(), so I'm pretty sure these were just typos...but I'd like some
eyes on it.

3. There are 2 tests that fail to build on Windows, which I've excluded
from the build but will open bug tickets for:
    1.  gemm_weight_preshuffle
    2.  grouped_gemm_preshuffle

Here's a sample of the compiler error for these tests:

test: Add umbrella test targets for CK Tile operations
 (#4301)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Proposed changes

Adds operation-specific umbrella test targets for CK Tile to enable
running all tests for a specific operation without running the entire
test suite. This improves the development workflow by allowing faster
iteration when working on specific operations.

## Motivation

Previously, developers working on CK Tile operations could only:
- Run individual test executables one at a time
- Run global labels (, , ) which test the entire codebase
- Build all tests for an operation but had no simple way to run them all

This made it cumbersome to validate changes to a specific operation
(e.g., GEMM quantization) without either running tests individually or
running the entire test suite.

### Documentation

- - Comprehensive testing guide with usage examples and implementation
details

## Usage Examples

# Run all GEMM tests with 256 parallel jobs
ninja -j256 ck_tile_gemm_tests

# Run all GEMM block scale (quantization) tests
ninja -j256 ck_tile_gemm_block_scale_tests

# Run all GEMM StreamK tests
ninja -j256 ck_tile_gemm_streamk_tests

[CK_TILE] Reduce Register Spills in Stream-K Reductions
 (#4984)

## Motivation

In CK Tile Stream-K, kernels using one of two non-atomic reduction
strategies (i.e., linear, tree) have high register spill count, with the
tree reduction generally being worse. These changes act a first step to
help decrease the register spill count.

## Technical Details
### Problem 1: Unvectorized access to partials
In both the linear and tree reductions, workgroups write partials
results to a global buffer; another workgroup will later read this data.
When the initial logic to support reading and writing to the partials
buffer was added (see
https://github.com/ROCm/composable_kernel/pull/3107), the tile
distribution encoding used to read from and write to partials matches
the register layout for the accumulator of the mfma instruction used for
the kernel. Since we do not currently use the transposed register layout
for the accumulator, we end with an encoding that is not optimized for
writing to HBM.

For example: Consider the register layout of the
`v_mfma_f32_16x16x32_fp8_fp8` instruction.
```bash
./matrix_calculator.py --architecture gfx942 --instruction  v_mfma_f32_16x16x32_fp8_fp8 --register-layout --C-matrix
```
<img width="1113" height="537" alt="image"
src="https://github.com/user-attachments/assets/afc8f556-08cc-4224-a6e5-b5edabc5fc02"
/>

The above shows that threads are responsible for consecutive elements
down a column of the C tile. If we use this distribution to read and
write to partials with C in row major, then threads are unable to
perform vectorized reads and writes. Note: thread 0 is shown in red and
thread 1 is shown in green.

Since the C-shuffle Epilogue only supports C in row major, reading and
writing to partials is highly unoptimized.
### Problem 2: Missed opportunity for SPGR use in tree reduction loop
Since the reduction occurs between workgroups, all threads in the
workgroup follow the same execution paths in the tree reduction logic,
hence various variables should be using SGPRs, but they are not.

### Implemented Solutions
1. Add a new tile distribution encoding that is optimized for accessing
partials in HBM. This encoding does not change the data assignment to
threads, it merely changes the addresses to which they write/read in the
partials buffer. For example, continuing with the
`v_mfma_f32_16x16x32_fp8_fp8` instruction, the new encoding would result
in threads writing in the following layout:
<img width="517" height="342" alt="image"
src="https://github.com/user-attachments/assets/93b5e0ea-bafc-47b8-89bb-c40ba75cb202"
/>

This layout ensures that each thread writes along a row, enabling
`buffer_{store|load}_dwordx4` instructions (i.e., vectorized accesses).
This helps reduce register usage due to requiring fewer offset
calculations.

2. To force SGPR usage in the tree reduction loop, I make use of CK
Tile's `amd_wave_read_first_lane` which is a wrapper around
`__builtin_amdgcn_readfirstlane`. This helps reduce VGPR spills in the
tree reduction.

_These changes do not fully eliminate register spills. Future work will
aim to further reduce spills. But these changes make good progress._

## Test Plan

Added tests for different warp tile sizes to validate that the new
encoding works with different `WarpGemm` variants.

## Test Result

All tests pass locally on all gfx9 architectures.

Some results for decreases in register spills on gfx942: (BL = baseline)
| Kernel | SGPR Spill (BL) | SGPR Spill (new) | SGPR Delta | SGPR % |
VGPR Spill (BL) | VGPR Spill (new) | VGPR Delta | VGPR % |

[CK_TILE] Fix CShuffleEpilogue test to use correct GEMM
 accumulator distribution (#4518)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

The test was using LDS distribution to create the accumulator tile, but
CShuffleEpilogue expects the GEMM accumulator distribution that
BlockGemm produces. This mismatch caused incorrect data permutation.

## Changes

- Use WarpGemmDispatcher to get correct accumulator distribution
encoding
- Load test input from host-initialized global memory for deterministic
verification
- Shard tests by data type (FP16, FP8) with gfx950-specific FP8 tests
- Extract scale tests into separate target for better organization
- Implement exact permutation verification (all unique values appear
once)
- Reduce tile size from 256x256 to 128x128 to fit in unique fp16 range
- Add parameterized test configurations for various warp layouts and
MFMA types

## Test plan

- [x] Run new cshuffle epilogue tests

[CK] Add split-K support for ABQuantGrouped in
 block_scale_gemm (#4816)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Changes

### Split-K support in `gemm_quant_kernel.hpp`

- **`SplitKBatchOffset`**: Added `aq_group_offset` and
`aq_k_split_offset` fields (mirroring the existing `bq_*` fields for B)
to track each split-K batch's position within the AQ scale tensor. For
`ABQuantGrouped`, both offsets are computed from `k_id * KRead` divided
by `AQuantGroupSize::kK`.

- **`MakeAQBlockWindow`**: Added an `aq_group_offset` parameter
(defaulting to 0 for non-split-K paths) so the AQ tensor view's K-group
dimension reflects only the remaining K-groups from the split-K offset,
consistent with how `MakeBQBlockWindow` handles the BQ tensor.

- **`RunGemm`**: Threads the `aq_k_split_offset` through to
`MakeAQBlockWindow` when in split-K mode.

### Constraints in `IsSupportedArgument()`

Four constraints gate split-K (`k_batch > 1`) for ABQuantGrouped:

1. **Mode check** — split-K is only allowed for `BQuantGrouped` (no
preshuffle) or `ABQuantGrouped` (no `APreshuffleQuant`). Any other quant
mode with `k_batch > 1` returns `false`.

2. **B quant group alignment** — `KRead` (per-batch K slice) must be
divisible by `BQuantGroupSize::kK`. Each batch must operate on complete
B quantization groups; a partial group would require splitting a scale
value across batches.

3. **A quant group alignment** (new, ABQuantGrouped only) — `KRead` must
also be divisible by `AQuantGroupSize::kK` for the same reason applied
to the AQ scale tensor.

4. **Minimum 2 K-tile iterations per batch** (new) — The
software-pipelined GEMM kernels (CompV3 family) prefetch one tile ahead,
so they require `per_batch_num_loop = KRead / KPerBlock >= 2`. When
`KRead == KPerBlock` (i.e. each batch is exactly one tile), the prefetch
reads into the next batch's memory region and produces incorrect
results. Configurations where `K == k_batch * KPerBlock` are therefore
rejected.

### Example update (`run_gemm_quant_example.inc`)

Updated the comment above the `IsSupportedArgument` call to document
that split-K is now supported for both `BQuantGrouped` (no preshuffle)
and `ABQuantGrouped` (no `APreshuffleQuant`).

## Unit Tests

Two new test files covering decode and prefill tile shapes across a
range of `k_batch` values (2–8), data types (FP8, BF8), and quantization
group sizes (1×1×128 and 1×128×128 for B):

- `test_gemm_quant_abquant_splitk_decode.cpp` — uses the decode tile
shape (M=16, N=64, K_tile=256)
- `test_gemm_quant_abquant_splitk_prefill.cpp` — uses the prefill tile
shape (M=128, N=128, K_tile=128)

Each test calls `run_test_with_validation` which runs the kernel and
checks correctness against a CPU reference. Configurations excluded from
tests are annotated with comments explaining which constraint they
violate (typically the `per_batch_num_loop >= 2` requirement).

This PR depends on #4429, which must be merged before this can be
merged.

should be disabled there by default.

## Technical Details

The test_fmha_fwd_fp8fp16 is the last failing test in CK on gfx90a with
staging compiler.

[CK_TILE] Extend support of mix precision microscaling BQuant
 (#4267)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Proposed changes

Supported types combinations using BQuant=e8m0:
 - A=bf16
 - B=bf16,bf8,fp4

Summary:
- remove usage of `pk_fp4_raw_t`: consistent with other implementations
and avoid taking into account of the packed size explicitly. In general,
the raw type should not be used because CK Tile internally takes care of
the PackedSize, so using the raw type adds unnecessary complexity to the
implementation
- handle microscaling by checking for `e8m0` type for BQuant (previous
implementation was inconsistent)
 - add support for scaling instructions in `DequantPack8`
 - mx pipeline:
   - extend existing pipeline to support different B types
- add support to scale and cast before writing to LDS or after reading
from LDS (this can be defined in the `Problem` by the user)
 - block gemm:
   - mx pipeline is now using block gemm BQuant
- block gemm BQuant can now load from LDS and apply scale and then call
block gemm universal operator. This adds new functionalities and remove
code duplication
 - warp gemm:
- add case to support 128bit ds_read/write for both A and B when A=16bit
and B=8bit
- add examples and tests: note that some tests for bf16/fp4 already
existed but were removed during previous tests refactoring. I added them
again and other relevant tests for new types combinations

[CK TILE] Refactor sequence_reverse_inclusive_scan

## Proposed changes

Refactor ck tile `sequence_reverse_inclusive_scan` from recursive to
for-loop.

Tracking issue: #4229

This pull request introduces a new lightweight array type,
`static_array`, and refactors the sequence utilities to use it for
improved constexpr support and simplicity. The changes also include
updates to the build system to add container-related tests.

**Core Library Improvements:**

* Added a new header `static_array.hpp` that defines the `static_array`
type, a constexpr-friendly array with basic accessors and no custom
constructors.
* Updated includes in `core.hpp` and `sequence.hpp` to import
`static_array`.

**Refactoring to Use `static_array`:**

* Refactored sequence utilities in `sequence.hpp` to use `static_array`
instead of the previously forward-declared `array` type, including in
histogram and array generation logic.
[[1]](diffhunk://#diff-5042e5b47bb2ba78bbab2d284338cf0503bc8fb76a7d631cc2684ad6ca832a76L1108-R1133)

* Rewrote the implementation of `sequence_reverse_inclusive_scan` to use
`static_array` for intermediate storage, improving constexpr evaluation
and clarity.

**Build System and Testing:**

* Added a new test subdirectory for container tests and a GoogleTest
executable for `unit_sequence.cpp` to the CMake build configuration.

fc3180120e [rocm-libraries] ROCm/rocm-libraries#4756 (commit 79bc2ca)
[CK_TILE] Update Stream-K Reduction Strategy Enum

## Motivation

Currently, Stream-K has 3 reduction options: 1) atomics, 2) The
reduction described in the Stream-K paper, and 3) a tree reduction. The
reduction strategy described in the original Stream-K paper has the
starting workgroup of each tile sequentially accumulating partial
results of other contributing workgroups in the tile, which requires a
linear number of steps. Hence, for clarity, this works updates the
naming of the `StreamKReductionStrategy` enum members to better describe
the existing reduction strategy options.

## Technical Details

Prior to this change, the enum is as follows:
```cpp
enum StreamKReductionStrategy : uint32_t
{
    Atomic        = 0u,
    Reduction     = 1u,
    TreeReduction = 2u
};
```
But, the distinction between `Reduction` and `TreeReduction` is not very
clear and has some redundancy.
Hence, the updated enum is as follows:
```cpp
enum StreamKReductionStrategy : uint32_t
{
    Atomic = 0u,
    Linear = 1u,
    Tree   = 2u
};
```
All references to `StreamKReductionStrategy` were updated to reflect
this change.
## Test Plan

No new functionality was added, so no new tests were added; I just
validated existing tests and examples.

## Test Result

All tests passed locally.

[CK_TILE][FMHA] Support gfx11

## Motivation

Add support of gfx11 architectures (RDNA3) to FMHA.

## Technical Details

Distributions (matrix elements to lane registers mapping) of gfx11 WMMA
are completely different from distributions of gfx9 MFMA and gfx12 WMMA.
There are two cases in FMHA where this difference matters:
* usage of results (matrix C) of one GEMM as input (matrix A) of another
GEMM.
* random number generation for dropout (implementation for gfx9 MFMA,
gfx12 WMMA and host validation produce the same results).

Both cases are solved by a special remapping implemented using
`__builtin_amdgcn_permlanex16` and `__builtin_amdgcn_perm`.

Additional changes:
* FMHA tests are now build and run only for those types for which
instances exist (gfx11 supports only fp16 and bf16).
* Two fixes for uninitialized values (`mask.sink` and
`do_fp8_static_quant`): they may contain garbage resulting in incorrect
dispatching logic, sometimes tests report that there are no instance
available for current parameters.
* Small fix to remove expcnt(0) from s_waitcnt instruction on gfx11 when
they are not requested (i.e. every time), likely has no effect on
performance but makes disassembly a bit clearer.

## Test Plan

```

## Test Result

All tests must pass (some tests may be skipped).

[CK TILE] fix numerical errors of preshuffle_b

This pull request introduces several improvements and fixes related to
quantized grouped GEMM (General Matrix Multiply) pipelines and their
supporting utilities.

# The numerical issue

## Steps to reproduce
```bash
Run
./bin/tile_example_gemm_weight_preshuffle -prec=fp8
./bin/tile_example_gemm_weight_preshuffle -prec=int4
```

# Solution
The main changes address type correctness, improve data layout and
shuffling logic, and expand test coverage to better validate different
GEMM configurations.

**Key changes include:**

### Data layout and shuffling logic

* Refactored the logic in `shuffle_b_permuteN` to use `constexpr`
variables for `KLane` and `ItemsPerAccess`, simplifying tile view
construction and correcting the permutation order for improved
efficiency and correctness (`tensor_shuffle_utils.hpp`).
* Fixed the calculation of `KLaneBytes` in weight preshuffle pipeline
policies to account for internal data type conversion (e.g., from
`pk_int4_t` to `fp8`), ensuring accurate memory access and alignment in
quantized GEMM policies (`wp_pipeline_agmem_bgmem_creg_base_policy.hpp`,
`gemm_wp_abquant_pipeline_ag_bg_cr_base_policy.hpp`).

### Test infrastructure enhancements

* Unit tests did not catch this issue since there were no tests for fp8.
Added new configuration structs (`config_mn_16x16`, `config_mn_32x32`)
to support additional GEMM tile shapes and updated tests to run with
these configurations for broader coverage
(`test_gemm_pipeline_util.hpp`).

…unding

Three tests were failing intermittently with small errors (0.01-1.5%)
due to non-deterministic FP16 accumulation order from GPU thread
scheduling:
- test_ck_tile_batched_gemm
- test_ck_tile_grouped_gemm_preshuffle
- test_ck_tile_grouped_gemm_multi_d

These tests use kbatch=1 (no split-K), so errors are from
order-dependent rounding, not atomics. Increased tolerances from 1e-3 to
2e-3 (0.2%) to account for FP16 precision limits while still catching
real bugs.

8cbd09c84a [CK_TILE] Stream-K Tile Engine Test Config File Generation (#3662)
* Stream-K smoke test config file generation

This change converts the stream-k smoke tests to use tile engine. Since
the m, n, and k values dependent on the CU count of a device, the
configs are generated during the Configuration Phase.

* Compute GEMM reference on GPU

* Remove redundant Stream-K tests

Removing redundant tests that are now run via tile engine.

* Fix relative and absolute tolerance calculation

This change updates the Stream-K tile engine interface to ensure that
num_wgs_per_tile is propaged and passed into the compare_results
function to calculate the rel and abs tolerance. Before, split-k was
used, which is incorrect for Stream-K since the split-k value is
always 1.

* Cleanup imports, types, and other misc items

This commit makes the following changes:
- Uses Typing module for nested type hints
- Uses quotes around cu_count_arg argument in generate_configs.cmake in
  if statements
- Adds explicit include for tuple in test_gemm_streamk_simple.cpp
- Adds a type for the tiles argument in argparser to check argument
  validity

* Use CU count as return value for better parsing

* Add reduction tests for bf16, fp8, and bf8

f5c2f09036 [CK_TILE] Fix alignment in Stream-K workspace buffer (#3625)
* Fix alignment issue in Stream-K workspace buffer

In CK Tile Stream-K, the workspace buffer is used to hold flags and
partials, where the first i bytes holds the flags and the remaining
bytes hold partials. This change adds padding to the flags prefix of the
workspace buffer to ensure the number of bytes is 128B-aligned. Without
this alignment, since workgroups do not skip cache when reading from
partials, they may read stale partials data in cache, leading to
incorrect results. The added padding avoids the stale data reading.

This change also re-enables the test_ck_tile_streamk_reduction tests.

* Compute reference GEMM on GPU for test verification to decrease testing time

* Addition of Stream-K tests using Tile Engine

This change adds an implementation for generating Stream-K tests using Tile Engine.
This will generate various test executables for different combinations based on the
config files. This addition has simple tests running for bf16 and fp16, with both
atomic and reduction strategies and compv3 pipeline. The tests rely on the implementation
of Stream-K in Tile Engine.

91b4102a59 Add persistent async input scheduler for GEMM kernels (#3520)
Add signal-based synchronization for persistent GEMM kernels where
input data becomes available incrementally. Uses modulo wraparound
(like PyTorch's AsyncMM) for chunk index calculation:
  chunk_idx = ((tile_idx + tile_idx_pivot) / tiles_per_chunk) % num_chunks

Key components:
- PersistentAsyncInputScheduler struct with tiles_per_chunk_m,
  chunk_signals, tile_idx_pivot_m, and num_chunks fields
- wait_eq_wave method using __builtin_amdgcn_s_sleep for power efficiency
- IsSupportedArgument validation for scheduler parameters
- Example demonstrating async input scheduling with simulated producer
- GTest unit tests covering all layout combinations

ec23be0b9d Update unsigned long literals and format specifiers to work correctly in Windows (#3483)
Previously, the code used unsigned long for literals and format specifiers to represent 64-bit unsigned values. While this worked on Linux, it caused compatibility issues on Windows.
The C++ standard does not guarantee that long is 64 bits. On LP64 systems (e.g., Linux), long maps to 64-bit values, but on LLP64 systems (e.g., Windows), long maps to 32-bit values. This discrepancy led to incorrect behavior when assuming unsigned long was always 64-bit.
This commit updates all relevant literals and format specifiers to explicitly use 64-bit unsigned types, ensuring consistent behavior across platforms.
