[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).

## Prerequisites

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

[CK] Disable test_fmha_fwd_fp8fp16 on gfx90a by default.
 (#4883)

## Motivation

Since gfx90a has no native support for FP8 datatype, all FP8 tests
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.

## Test Plan

<!-- Explain any relevant testing done to verify this PR. -->

## Test Result

<!-- Briefly summarize test outcomes. -->

[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

## Checklist

Please put an `x` into the boxes that apply. You can also fill these out
after creating the PR. If you're not sure, please don't hesitate to ask.

[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

```
ninja test_ck_tile_fmha

bin/test_ck_tile_fmha_fwd_fp16
bin/test_ck_tile_fmha_fwd_bf16
bin/test_ck_tile_fmha_bwd_fp16
bin/test_ck_tile_fmha_bwd_bf16
```

## 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

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

7f912909ca Disable CK Tile Stream-K reduction tests (#3559)
The test_ck_tile_streamk_reduction test suite seems to have transient
failures; hence, we are disabling these tests for now. We will re-enable
them once the bug is resolved.

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.

ea10a78203 [ck_tile] refactor reduce kernel (#3257)
* refactor reduce kernel

- Rename Reduce kernel as per convention

- Move kept_dim and reduce_dims from runtime to compile-time parameters

- Update Reduce2dProblem template to include KeptDim, ReduceDims, and
Rank

- Remove IsSupportedArgument validation function as it's unnecessary.
Not using the GuaranteedLastDimensionVectorStride while making tensor
view or descriptor which removes the bounds enforced earlier. We still
calculate and use vector size.

- Update reduce example to demonstrate NCHW->NHW reduction with
non-contiguous support

- Update tests

Kernel now handles both contiguous and non-contiguous memory layout.

22b945e06e [CK_TILE] Stream-K Tree Reduction and Cache Skipping Integration (#3371)
* CK Tile Stream-K Tree Reduction

This change adds the first implementation of the Stream-K tree reduction
strategy into CK Tile. The tree reduction reduces the the number of
steps for accumulating results for a tile from O(N) to O(logN) where N
is the number of workgroups contributing to a C tile.

Additionally, in the original non-atomic reduction strategy, atomics
were used to set the flags buffer and to read from the flags buffer.
Howeover, through investigation with the tree reduciton, atomics with
default (relaxed) semantics were not enough to guarantee workgroups
would not read stale data, leading to incorrect results. Stronger
acquire/release memory orderings are too expensive. So, this change
also eliminates the use of atomics for setting the flags. Instead, we
leverage cache modifiers (e.g., GLC) to avoid writing to cache, thereby
avoiding the use of atomics.

Prelimiary tests were also added for the normal reduction and tree
reduction. More will be added in a future PR via tile engine.

* Move Stream-K kernel files to a subdirectory

* Cleanup Code Style & Handle Unsupported Reductions

This change makes the following small changes:
- Add an explicit else block for unimplemented reduction strategies
- Clarify type of sk_flags_ptr via auto*
- Add description for extra_iters_before_me variable

* Run new copyright script on new files
