2b4fff113d [CK] Replace tuple value construction with tuple_element_t type extraction [1A] (#5030)
## Summary

### Rationale
CK's device operation instance registration uses
`add_device_operation_instances` at ~1,850
call sites to register GPU kernel configurations. The existing
implementation constructs
`std::tuple` values just to extract their types via `decltype`, then
copy-constructs each
instance into `make_unique`. This is wasteful — only the types matter,
not the values — and
forces the compiler to instantiate the full `std::tuple` constructor and
`std::get` machinery
at every call site.

### What changed
- Replace `remove_cvref_t<decltype(std::get<i>(tuple_obj))>` with
`std::tuple_element_t<i.value, TupleType>`, which extracts the type
directly without constructing any values
- Replace copy-from-default `make_unique<T>(value)` with direct default
construction `make_unique<T>()` — all CK device operation instances are
stateless structs with configuration encoded in template parameters
- Add `static_assert(std::is_default_constructible_v<NewOpInstance>)` to
enforce this contract at compile time with a clear error message
- Add Doxygen documentation for this high-traffic public API

### Value
- Eliminates unnecessary template instantiation of `std::tuple`
constructors and `std::get` across ~1,850 call sites
- Establishes a cleaner, more intention-revealing pattern for type-only
tuple usage
- The `static_assert` prevents silent breakage if a
non-default-constructible type is ever added
- No runtime behavior change — zero risk

### Files changed (9)
- `add_device_operation_instance.hpp`: Core pattern change
- 3 example files, 3 reduce instance headers, 1 convolution header, 1
profiler header

## Test plan
- [ ] Existing CI tests cover all ~1,850 call sites (GEMM, reduce,
softmax, convolution)
- [ ] `static_assert` provides compile-time validation stronger than
runtime tests
- [ ] No runtime behavior change — stateless struct default construction
is identical to copy-from-default
- [ ] Compatible with both `std::tuple` and `ck::type_list` containers

1e8cde4b6d [CK_TILE] Add CK Tile bwd weight profiler (#4797)
## Motivation

To compare old CK and CK Tile, we need to extend the current CK profiler
to support running also CK Tile instance with the same API. In order to
have the same instance coverage in CK Tile compared to the old CK, I've
added code generation from old CK configurations to CK Tile instances
using the CK Builder.

## Technical Details

- The codegen python script for CK Tile fwd convs is extended to support
also bwd weight and bwd data.
- The generated instances are added to the CMake build (target
`device_grouped_conv_bwd_weight_tile_instance`s).
- A new profiler op (`grouped_conv_bwd_weight_tile`) has been added to
the CK Profiler.

4a6638adcf [CK_TILE][FMHA] Extend pipelines with pssk for gfx11/12 (#4957)
## Motivation

Build pipelines with seqlen padding only to support vectorized loads in
the hdim dimension.
The existing pipelines have either all dims padded or all dims not
padded.
These pipelines can be used in ComfyUI for slightly better performance.

## Technical Details

Also a fix included for correct FLOPS calculation in
`tile_example_fmha_fwd` when `seqlen_q * seqlen_k` overflows index_t
capacity (signed int32).

## Test Plan

The existing test cases will use the new pipelines when parameters allow
(seqlens - padded, hdims - not padded):
```
ninja test_ck_tile_fmha_fwd

bin/test_ck_tile_fmha_fwd_fp16
bin/test_ck_tile_fmha_fwd_bf16

bin/test_ck_tile_fmha_fwd_fp8bf16 # for gfx12
```

## Test Result

All tests must pass.

e454358113 [CK_TILE] FMHA BWD Launcher Interface (#4577)
## Motivation
Reduce memory usage; Be prepared to implement optimizations of reducing
nsplits in deterministic cases.

## Technical Details
This PR introduces a new launcher interface for the FMHA backward
operation, replacing direct function calls with a more structured
approach. The launcher encapsulates kernel dispatch logic and provides
access to computed metadata like the number of dQ acc splits.

**Changes:**
- Added `fmha_bwd_launcher` class that wraps kernel execution and
exposes `dq_acc_splits`
- Moved `fmha_bwd_traits` construction earlier in the execution flow to
support launcher initialization
- Refactored code generation to produce both legacy API and new launcher
constructor

## Test Plan

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

## Test Result

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

5cc04d7676 [CK] Address a bunch of errors associated with targeting gfx1200 on Windows (#5045)
## 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:

2fcb94c18a Add Tile Distribution Encoding Register Mapping debug utility for MFMA / WMMA unification work. (#4804)
## Motivation

This PR adds a small utility that allows you to use Tile Distribution
Encodings to directly map matrix elements to register locations and vice
versa. It can also print forward and backward layout mappings similar to
the Matrix Calculator utility. The utility is not meant for index
calculations in actual kernels, but rather as a debugging tool and
probably for automated verification of the policy structs in the new
WMMA / MFMA unification design.

## Technical Details

Tile Distribution Encodings are a core part of CK Tile which can define
the relationship between register and intrinsic matrix fragment
elements. They allow for any mapping based on unmerge and merge
transformations. Also, they allow for a special "Repeat" dimensions
which acts like an additional matrix dimension and allows for
replication of certain matrix elements. The new mapping utility can deal
with all aspects.

## Test Plan

Since this is a debug utility there is nothing to directly test, but
there is an example file that defines four different Tile Distribution
Encodings and prints their forward and backward mappings, along with
some extra parameters.

20755a0bd2 [CK] Add split-K support for ABQuantGrouped in block_scale_gemm (#4816)
## 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.

## Technical Details

The file:
[fmha_fwd_appendkv.py](https://github.com/ROCm/rocm-libraries/compare/users/brockhargreaves-amd/ck/fix-windows-cmake-path-problem?expand=1#diff-bef22bf9ba21eb93c725493ecc7edcb6f2a8f0a9a173dcfca6bda7a9f4eced78)
writes a bunch of paths to a text file which is later parsed by cmake.
When passing a pathlib.Path to str(), str() converts to a native path,
in this case / to \\ on Windows which confuses cmake. In this case we
need to write paths with forward slashes and then pass those onward to
cmake.

## Test Plan

1. Ensure this doesn't impact existing CI. 
2. Ensure compilation of Windows pass locally.

## Test Result

1. Passes existing CI
2. This fixes the compilation error locally.

6c9436d0e5 [CK] Fix windows build issues (#4819)
## Motivation

Full build on Windows is currently broken due to compiler errors, this
PR should help fix that. This is also holding up the following PR in the
TheRock: https://github.com/ROCm/TheRock/pull/3382

## Technical Details

1. I don't see a good reason to be nesting a windows include inside the
ck_tile namespace. It was causing compiler errors too: Windows.h comes
with min and max, which was conflicting with ck_tile::min and
ck_tile::max, so I moved it out. I also defined NOMINMAX to prevent this
inclusion in the future.
2. The TRUE/FALSE macros are already used by Windows.h, which causes an
error. So I've opted for True/False. You can see this pattern in other
rocm-libraries.
3. The M_PI macro isn't available, at least in the WIN32_LEAN_AND_MEAN
context, from \<cmath\> on Windows. We'll be able to use
std::numbers::v_pi\<float\> when we have C++20 support.
4. There was a missing \<chrono\> include.


## Test Plan

Test locally and make sure this doesn't impact existing CI.

## Test Result

Compiles locally and passes existing ci.

29c7a98292 [CK] Implement device grouped gemm fixed nk multi abd for rdna4 (#4425)
## Motivation

Add support for grouped gemm multi ABD fixed NK. MR

## Technical Details

Changes from the reverted PR:
- Device struct for grouped gemm with multiple ABD and fixed NK
(DeviceGroupedGemm_Wmma_Multi_ABD_Fixed_NK).
- Wmma versions of existing example codes: 59_grouped_gemm_multi_ABD
- Unit tests for both new wmma implementation and the reference xdl code
(previously missing)
- Note: Some Xdl instances were commented out because of unit test
failures. As mentioned apparently for xdl this feature was missing tests
so our assumption is either there is an implemenetation bug or these
instances were not set up correctly. Has the potential for a follow-up
issue.
- Generic ck profiler interface with the purpose of calling unit tests.
- Gemm instances with specific elementwise operations for gemm bias gelu
calculations.
- Added class for grouped gemm multi ABD reference calculations.

Fix epilogue selection in device implementation that caused unit test
failures

## Test Plan

Covered by added unit tests

## Test Result

CI successfully passing

45c177c384 [CK_TILE] Extend support of mix precision microscaling BQuant (#4267)
## 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.

- [ ] I have added tests relevant to the introduced functionality, and
the unit tests are passing locally
- [ ] I have added the test to REGRESSION_TESTS list defined at the top

cf00dc87d0 [CK_TILE] Update Stream-K Reduction Strategy Enum (#4756)
## 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.

ce6acc5f66 [CK_TILE][FMHA] Support gfx11 (#4584)
## 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).

fc19663d91 173 implement device grouped gemm fixed nk for rdna4 (#4299)
## Proposed changes

This PR adds an RDNA4 implementation of the device_grouped_gemm_fixed_nk
instance library using for WMMA.

The implementation is based on the existing
DeviceGroupedGemm_Xdl_Fixed_NK design and reuses the same high-level
structure, but replaces the XDL kernel with a WMMA-based one. It uses
the GridwiseGemm_wmma_cshuffle_v3 kernel.

At this stage, the focus is functional correctness and compatibility,
not performance tuning.

## Technical Details

- Device struct for grouped gemm fixed NK
- Example code for the WMMA version
- Unit tests for both new wmma implementation and the reference XDL code
(previously missing)
- Generic ck profiler interface with the purpose of calling unit tests.

15635d4b11 [CK TILE] fix numerical errors of preshuffle_b (#4354)
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`).

1ac61a54c9 [CK_TILE] Blockscale Gemm Fix Multi-Arch Compilation (#4451)
## Motivation
This PR updates CK_TILE blockscale GEMM-quant kernels and launch helpers
to compile across multiple GPU architectures by introducing compile-time
availability gating and a new attribute tag mechanism for kernel
symbol/attribute specialization.

## Technical Details
- Add an architecture-guarded `kIsAvailable` flag to the gfx950 pipeline
and propagate availability handling into `QuantGemmKernel`.
- Extend `make_kernel`/`kentry` to accept an `Attr` tag enabling
per-kernel compile-time attributes (e.g., `no-packed-fp32-ops`) and
unique symbols.
- Update the blockscale GEMM quant example to pass kernel attributes and
adjust gfx950 gating.

## Test Plan
- CI
- Local test: `cmake .. --preset dev -DGPU_TARGETS='gfx942;gfx950'
-GNinja && ninja tile_example_gemm_quant`
- Local test with ROCm/aiter#1954

dfa95522d3 [CK_TILE] Add support and tests for V6 pipeline in conv fwd (#4357)
Added support for conv v6 pipeline in ck tile's convolution forward
kernel. CK Tile v6 pipeline is the equivalent to old ck's V5 pipeline
and should be faster than other pipelines for some cases. This PR also
adds tests inside profiler that's currently inside experimental
directory, so now we should be able to detect regressions easier.

470f031e58 [Compiler] Addressing new compiler warnings (#3640)
* [Compiler] Addressing new compiler warnings

Clang enables new lifetime warnings in production and we see build
errors due to this with the staging compiler.

The attributes added in this PR are suggested by the compiler. However,
I'm not very familiar with the code base, so the changes may be
incorrect.

* Update some more instances

* Adds file-level ignores via clang diagnostic pragma

The number of instances was large, so I decided to use file-level scope
to disable the warning via pragma clang diagnostic ignored.

It also showed this warning coming from the gtest dependency. For that,
I did add the respective command line flag to the CMake variables. I
don't know if this is acceptable or not.

* This adds the remaining instances

For a build on gfx90a.

* fix clang format

* Adding couple more instances from gfx1200 build

* Fixed another few instances

65c2e81817 Adding remaining conv, dynamic_op, and scaleadd_scaleadd_relu flavors for grouped conv fwd (#3529)
* Adding remaining flavors for grouped conv fwd

As titled. Following variants are added:
- grouped_conv2d_fwd_dynamic_op
- grouped_conv3d_fwd_dynamic_op
- grouped_conv3d_fwd_bilinear
- grouped_conv3d_fwd_convscale
- grouped_conv3d_fwd_convinvscale
- grouped_conv3d_fwd_convscale_add
- grouped_conv3d_fwd_convscale_relu
- grouped_conv3d_fwd_scale
- grouped_conv3d_fwd_combconvscale
- grouped_conv3d_fwd_scaleadd_scaleadd_relu

* Fix incomplete parsing of types from source names in add_instance_library() cmakelists function so we don't build f8 on RDNA3.

* Do not build f8 / bf8 only flavor tests on RDNA3

* Make sure we have proper generic instances for all instance lists related to the post-ces extra flavors, with scalarPerVector = 1. Then disable all but one generic instance per instance list to reduce compile time.

* Post rebase fix: Template parameters for Grouped Conv Fwd Device Impl got tweaked upstream.

* adding int8 and fp16 overloads to the elementwise operations

* fixed copilot nits

* Addressing review comments:

- removed unnecessary examples for dynamic op
- removed unnecessary conv specalizations for all the flavors
- removed spurious bilinear and scale source files

* clang-format

* reduced no of tests
