[CK] Fix and expand CK's commit records in version.h (#6900)

## Motivation

In `version.h` of a CK installation `CK_COMMIT_ID` would be empty for
out-of-source builds.
Additionally, if it worked, it would show the parent repo's
(`rocm-libraries`) commit.

## Technical Details

Dropped "required" constraint so "unknown" string becomes a graceful
option.

Changed process of determining the CK commit, now uses
`WORKING_DIRECTORY`.
Thus, `CK_COMMIT_ID` holds only the last CK-relevant commit.

Added `CK_PARENT_COMMIT_ID` which holds the parent's, e.g.
`rocm-libraries`, commit.
This can be the same as `CK_COMMIT_ID`, or not even applicable,
depending on the scenario.

## Test Plan

Ran CMake configuration and installation of CK to verify happy path.

## Test Result

Commit SHA's showed the expected values depending on the repo state.

[CK] CompV4: remove redundant barrier (+5.7% gfx942, +1% gfx950) (#7442)

## Summary

- Remove one redundant `block_sync_lds()` from the pong phase of the
CompV4 GEMM pipeline hot loop
- The pong phase had 2 barriers while ping had 1 — the second pong
barrier (after LDS writes, before global loads) was unnecessary because
the sync at the top of the next ping iteration already ensures LDS
coherence
- Removing this barrier allows global loads to overlap with LDS write
drain, restoring the latency hiding the ping-pong design was built to
provide
- Abstracting away Ping Pong phases into generic lambda avoids making
such mistake again.

c24e528481 [rocm-libraries] ROCm/rocm-libraries#7760 (commit a61bc76)
[CK] suppress compiler warnings while building pytorch. (#7760)

## Motivation

Recently added compiler flags that are required to suppress false
warnings by latest staging compiler are not recognized by older compiler
versions and are triggering an avalanche of warnings. Previous attempt
to suppress them by using -Wno-unknown-warning-option flag didn't help,
because that flag wasn't recognized either and just added more warnings.
I've verified that current approach by checking the clang version
actually works as intended and makes the warnings go away.

00e1d82ae7 [rocm-libraries] ROCm/rocm-libraries#7732 (commit b0e29d9)
[CK] Fix grouped conv bwd data stride>1 silent miscompute (ALMIOPEN-1959) (#7732)

## Motivation

Fix silent miscompute in the grouped convolution backward-data kernel
(`DeviceGroupedConvBwdDataMultipleD_Xdl_CShuffle_v1`) when stride >
dilation (ALMIOPEN-1959). PR #6208 introduced a flat-descriptor fast
path that dropped all but the first sub-GEMM, producing zeroed slices of
`dx` on
the (G=1, stride>1, 2D, NumDTensor=0) intersection. Restore correctness
without giving up the perf gains PR #6208 delivered on stride=1 shapes.

## Technical Details

- Tighten the flat-descriptor fast-path gate to require
`arg.gemms_count_ == 1` (i.e. a single sub-GEMM per dispatch — its
original purpose). For stride > 1, the implicit GEMM is split into
`gemms_count_` sub-GEMMs whose output cells tile `dx` disjointly;
routing them through the flat path required dropping all but the first,
which was the source of the bug.
- Stride > 1 now falls through to the existing grouped CShuffle path,
which packs all sub-GEMMs into one descriptor array and walks them
on-device in a single kernel launch. This is the pre-PR-6208 production
path; correctness is established and per-dispatch launch count is
minimised.
- Add regression coverage for the (G=1, stride>1, 2D, NumDTensor=0)
intersection in
`test/grouped_convnd_bwd_data/test_grouped_convnd_bwd_data.cpp` with
`gemms_count` ∈ {4, 9, 36}. Pre-existing cases did not hit this
intersection (all stride>1 cases used G=2; all G=1 cases used stride=1),
which is why PR #6208's regression slipped past CI.

## Test Plan

- `ctest -L SMOKE_TEST -R 'grouped_convnd_bwd_data'` on gfx942 (smoke
tier — runs on every PR via `smart_build_and_test.sh`).
- End-to-end verify (`verify=1`) via
`example_grouped_conv_bwd_data_xdl_fp16` on stride 1/2/3/6 shapes
including the original ALMIOPEN-1959 case and a cross-bucket
(`gemms_count=36`) case spanning two `MaxGroupedGemmGroupsNum=32`
buckets.
- ckProfiler A/B sweep on MI300X (gfx942) toggling the flat-path gate
via an environment variable: full kernel-family enumeration, winning
kernel + its avg_time reported under each gate. 33/41 shapes completed
before the sweep was stopped; the remaining 8 were the largest
i2v/synthetic shapes where ckProfiler exceeded its 300s per-shape
enumeration budget (not relevant to the verdict).

## Test Result

### Correctness

| Test | Result |
|---|:---:|
| `test_grouped_convnd_bwd_data` (12 type parameterizations × Test2D,
includes 3 new regression shapes) | **12/12 PASSED** in 14.18 s |
| `test_grouped_convnd_bwd_data_interface` (API checks) | **PASSED** in
0.28 s |
| ALMIOPEN-1959 stride=2 (`verify=1`) | **PASSED** |
| stride=1 K3 (`verify=1`) | **PASSED** |
| stride=3 K3 `gemms_count=9` (`verify=1`) | **PASSED** |
| stride=6 K6 `gemms_count=36` cross-bucket (`verify=1`) | **PASSED** |

### Performance (ckProfiler A/B on gfx942 / MI300X)

Comparing the **post-fix gate** (flat path only when `gemms_count_==1`,
column "B") vs the **inner-loop variant** that keeps the flat path on
stride>1 (column "A") across 25 stride>1 shapes where production picks
a `_v1` instance (so the gate actually fires):

| Stride | Shapes | A wins | Tie | B wins | Notes |
|:------:|:------:|:------:|:---:|:------:|---|
| 1 (sanity, gate moot) | 3 | 0 | 3 | 0 | gate doesn't differentiate — A
== B as expected |
| > 1 (gate fires) | 25 | **0** | 11 | **14** | B wins +6% to +32%; A
never wins |

Highlights from the firing-gate cases:

| Shape (G=1, stride=2 unless noted) | A ms | B ms | B vs A |
|---|---:|---:|---:|
| ALMIOPEN-1959 (N=16, K=256, C=128, 5×5, 40×175) | 0.183 | 0.171 | **B
+6%** |
| Retinanet-L61 (N=32, K=C=256, 3×3, 25×25) | 0.054 | 0.045 | **B +17%**
|
| i2v-010 (N=1, K=C=384, 3×3, 277×209) | 0.174 | 0.125 | **B +28%** |
| Synthetic 50×50 K3 N=32 K=C=256 | 0.131 | 0.088 | **B +32%** |

Why B wins everywhere the gate fires: for `gemms_count = N`, the flat
path needs N kernel launches (one per sub-GEMM), while the grouped path
loops over the same N sub-GEMMs on-device in 1 launch. The (N−1) ×
launch-tax is a structural disadvantage A can't recover from.

### Diff

| File | Lines |
|---|---:|
|
`include/.../device_grouped_conv_bwd_data_multiple_d_xdl_cshuffle_v1.hpp`
| +14 / −8 (one extra condition + expanded dispatch comment) |
| `test/.../test_grouped_convnd_bwd_data.cpp` | +9 / −0 (3 new shapes) |

[CK_TILE] Stream-K XCD remapping (#4279)

## Proposed changes

This PR adds support for XCD remapping as detailed in this
[document](https://amdcloud.sharepoint.com/:w:/r/sites/ComposableKernels/Shared%20Documents/Stream-K/Design%20Docs/XCD%20Mapping.docx?d=w2df1b0737dc54614970d99a2e26022d1&csf=1&web=1&e=mLVN4A).
On gfx942, workgroups are typically scheduled round-robin across XCDs,
which can lead to poor locality. We will use a remapping to assign
workgroups to contiguous tiles in the XCDs improving the locality and
the cache hit rate. This is done through a function that computes this
contiguous mapping from this
[PR](https://github.com/ROCm/composable_kernel/pull/3161), which we have
added to the StreamKTilePartitioner. This will require minimal changes
to the Stream-K algorithm, only requiring a remap at the time the
workgroups are partitioned. Through this approach we can improve the
data locality by improving cache hits therefore closing performance gaps
that are seen with the default scheduling. There have been unit tests
added to verify the function in isolation. This is an optimization that
is not specialized to just Stream-K GEMM and can be applied across GEMM.

Note: This only applies to the gfx942 as they introduce the XCDs.

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] Adding steps in Stream-K Tile Engine (#6511)

## Motivation
This PR adds step functionality to the Stream-K instance generator in
Tile Engine in order to quickly generate instance configurations within
a certain max/min range. To complement this, the Stream-K Tile Engine
validation file has been updated for more rigorous validation of
generated instances.

## Technical Details
- Added _generate_values helper to support min/max/step range-based tile
config generation, matching Universal GEMM
- Added validate_gemm, validate_whole_wg_cover_configuration,
validate_cshuffle_epilogue_distribution, and other supporting functions
to the Stream-K validation utils, aligning with the validation already
present in the Universal GEMM

## Test Plan
Tested using the generation in CK Tile Engine

## Test Result
All instances were generated and validated correctly.

[CK_TILE][FMHA] Improve precision of mxfp4 FMHA with fp6 for matrix P (#5388)

## Motivation

Improve precision of mxfp4 without performance penalties.

## Technical Details

Since performance of scale MFMAs is the same when neither A nor B is
fp8/bf8, it is possible to use fp6 x fp4 instead of fp4 x fp4 for the
second GEMM, while types of Q, K, V stay the same.
This allows to improve overall precision significantly because fp6 has
32 non-negative values used for P quantization compared to just 8 values
for fp4.

It was found that there is a compiler bug with
`__builtin_amdgcn_cvt_scalef32_2xpk16_fp6_f32` (described in
LCOMPILER-561) but a workaround seems to fix all failing instances.

## Test Plan

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

## Test Result

The tests must pass.

d65ad35b23 [rocm-libraries] ROCm/rocm-libraries#7180 (commit 54aed1e)
[CK] Add rocm_ck spec factories: GemmSpec, makeSpec() (#7180)

## What this PR does

This is the third PR in the rocm_ck schema stack:

1. **#7150** — Foundation types (DataType, Layout, Args, Ops)
2. **#7163** — Schema engine (Signature, resolve(), ArchProperties)
3. **#7180 (this)** — Spec factories (GemmSpec, makeSpec())

`makeSpec()` is the bridge between user intent and kernel instantiation.
It takes a **Signature** (WHAT to compute — operator graph, dtypes,
layouts) and a **GemmAlgorithm** (HOW to compute it — tile sizes,
pipeline, partitioning) and produces a validated `GemmSpec` — a
structural type ready to use as a non-type template parameter.

The key property: **every constraint is enforced at compile time.** An
invalid GEMM configuration is a compile error, not a runtime crash or
silent corruption. The 33 compile-fail tests are the executable
specification of what's allowed.

## What's interesting

**Physical tensor table.** Not every tensor in a compute graph needs
device memory. The intermediate result of `C = A * B` in a fused
GEMM+Add+ReLU lives only in registers. `makeSpec()` walks the operator
chain and determines which tensors are physical (need Args slots) and
which are intermediate. The output is a fixed-layout table: `[lhs, rhs,
output, D0?, D1?, scale?]`.

**Epilogue composition.** Instead of a combinatorial explosion of named
patterns (GemmAdd, GemmAddRelu, GemmMulSilu, ...), the epilogue is a
composable chain of ops. `{GemmOp, AddOp, ReluOp}` produces
`epilogue_ops = {Add, Relu}` with the bias tensor automatically slotted
as D0. Two consecutive AddOps fold into a single Add with two D tensors
via CK Tile's parameter pack.

**Signature/Algorithm split.** The same Signature can pair with multiple
GemmAlgorithms to produce different tuning variants without changing the
mathematical result. This is the foundation for the dispatcher — one
operation description, many tile configurations.

## New types

| Type | Role |
|------|------|
| `GemmSpec` | Validated NTTP kernel descriptor — physical tensors, tile
geometry, epilogue chain |
| `GemmAlgorithm` | User-facing tuning input — tile sizes, pipeline,
partitioning, padding |
| `EpilogueOp` | NTTP-compatible projection of the Op variant for
epilogue chains |
| `Dim3` | M x N x K triple for tile geometry |

## Test coverage

- **69 unit tests** — happy paths, layouts, dtypes, quantization,
epilogue chains, algorithm variants
- **33 compile-fail tests** — one per constraint (tile divisibility,
INT8 rules, pipeline restrictions, etc.)
- **6 schema compatibility baselines** — frozen specs that break if the
schema changes

6a9c03f692 [rocm-libraries] ROCm/rocm-libraries#7450 (commit 402dbad)
[CK_TILE] Use Persistent Scheduling for FMHA BWD Group Deterministic (#7450)

## Motivation

FMHA BWD group-mode deterministic currently uses a non-persistent
scheduler: each `(batch, head, K-row)` work-item is launched as its own
block, with no work-stealing across CUs. On uneven workloads (varlen,
GQA, many heads with
few K-rows) this leaves CUs idle and forces a larger dq_acc workspace
than necessary.

This PR ports the persistent + deterministic scheduling already used in
batch mode to group mode: a fixed-grid kernel that pre-computes per-CU
work ranges on the host and uses sparse dq_acc slot indexing so multiple
K-rows handled
by the same CU share one accumulator slot via intra-CU atomic adds.

Stacked on #7331; merge that first.

## Technical Details

Single file changed: `ops/fmha/kernel/fmha_bwd_kernel.hpp`.

A new `kUsePersistent` path is added to the group-mode deterministic
kernel, mirroring the batch-mode persistent scheduler. The host
pre-computes a fixed per-CU partition of the total `(batch, head,
K-row)` work and packs it into
`cu_states[]` so the GPU consumes it in a single launch. Host
preparation happens in four steps:

1. Build per-batch `seqstart` prefix sums.
2. Fill per-batch `(sq_w, nc)` with a placeholder `nsplits` (bumped in
step 3).
3. Two-pointer scan over CUs to fill `cu_states[c]` (`isplit`,
`head_start`, `c_start`, `w_lo`, `w_hi`), accumulating `nsplits[b]` as
`max(cs->isplit + 1)`.
4. Compute compact per-batch dq_acc offsets from the finalized
`nsplits`.

`isplit` is the sparse dq_acc slot index — one CU's multi-K-row writes
share slot `ceil(wc_start / denom)`, enabling intra-CU atomic
accumulation instead of one slot per K-row.

`denom = max(sq_w, target_w)`, splitting two regimes:

- `target_w >= sq_w` (large work): `denom = target_w`, intra-CU atomic
optimization engaged.
- `target_w < sq_w` (sub-K-row sharding, multiple CUs sharing one
K-row): `denom = sq_w` collapses to per-K-row indexing (`= c_start`),
keeping `isplit ∈ [0, nc-1]` and matching the `nsplits_max =
ceil(s_k/kN0) = nc` upper bound that #7331's
`GetWorkspaceDeviceSizeUpperBound` assumes for group+det.

`isplit` is additionally clamped to `nc-1` to absorb empty CUs
(rounded-up `wc_start` past the last K-row); they don't write dq_acc on
GPU so the slot value is harmless.

`nsplits[b]` is accumulated dynamically in step 3 rather than via a
closed form so it tightly matches the actual sparse slots used; step 4
(offsets) follows step 3 since offsets now depend on the dynamic
`nsplits`.

Group mode also allows batches with `seqlen_q == 0`. The persistent
scheduler skips them on the dQ path (no work) but dK/dV are still
zero-filled.

## Test Plan

Built `tile_example_fmha_bwd` with receipt 5 (fp16, no-bias, no-dropout,
`dpad == dvpad`, group + batch) on gfx950 (MI355X).

- 8-case smoke (shapes that exercise the sub-K-row regime).
- 44-case sweep covering: mask 0/1/2, GQA, var seqlen, `d != d_v`,
extreme
  small seqlen / `nc=1`, CU >> work, huge batch, batch-mode regression.
- 12-case perf comparison vs the non-persistent baseline (warmup=10,
  repeat=50).

## Test Result

- All 8 + 44 cases `valid:y`.
- Perf: ±5% noise, average -0.4% across the 12 cases — neutral.
- Batch-mode deterministic / non-deterministic regression unchanged.

c7fac341de [rocm-libraries] ROCm/rocm-libraries#4871 (commit 7d4c040)
[CK] Decouple EpilogueArgs from GridwiseGemm implementation (#4871)

This is duplicate of #4537. I could not re-open it since te target
branch got deleted and could not change the target branch since it was
closed... :)

## Motivation

Right now, all the Epilogues structs are declared inside the base
gridwise struct. They should be independent of it and the specialization
of the selected Epilogue Type should be declared within the the kernel
function.

## Technical Details

All Epilogue structs depend on template parameters that are known to the
base Gridwise Gemm struct. In this PR, we export them to be used
independently by any struct that might need to extract them. This
approach will serve the decoupling purposes for the Epilogues, but also
enable future constructs to use and expand this approach. See
30e2a4c01b64bdea68857c7badd9d7cffbf1adb9.

Right now an issue that arises is that when implementing a new Epilogue
Type, the developer is not forced to decide where this struct should/can
be used or not. To fix this I propose defining an `enum struct
EpilogueType` that will be used to fetch the Epilogue specialization
through a helper struct. See a943ac8d130e12d6843715b322181186e54ba15c.
Note that all the instantiation details will stay in this helper struct.
Also note the static assertion in the else statement.

## Test Plan

Test with existing CI, as nothing is added/removed.

## Test Result

All relevant existing CI tests should pass.

b1975951d4 [rocm-libraries] ROCm/rocm-libraries#7179 (commit 05edc86)
[CK] Add rocm_ck schema engine: Signature, resolve(), ArchProperties (#7179)

## Summary

A `Signature` is a directed compute graph: tensors are nodes, operators
are edges. Shared names between operator outputs and inputs form the
graph structure. `resolve()` walks this graph at compile time
(`consteval`), inferring dtype, rank, and layout for every tensor —
invalid configs become compiler errors, not runtime crashes.

**Key design decisions:**

- **Operators teach the system about tensors.** `GemmOp` implies rank 2
and Row/Col/Row layout. `AddOp` and `ReluOp` propagate from connected
slots. The dtype cascade fills in the rest: per-tensor → signature-wide
→ error.

- **Adding a new op is zero lines in the resolution engine** if it's
structurally binary (`lhs/rhs/out`) or unary (`in/out`) — C++20 concepts
handle dispatch automatically. Only ops with special semantics need
explicit branches.

- **TargetSet is a compile-time bitset over GPU targets.** The wave tile
validation table is the single source of truth for valid instruction
shapes, traced from CK Tile's WarpGemmDispatcher. FP8 tiles are
available on gfx942+ via IterateK composition, not gfx950-only.

**Reading order:** signature.hpp (data model) → arch_properties.hpp
(TargetSet, wave tiles) → resolve.hpp (resolution engine).

3 new headers, 3 unit tests (including diamond DAG coverage), 3
compile-fail tests. Introduces tests/compile_fail/ infrastructure.

**Stack**: PR 2 of 3 porting the rocm_ck constexpr schema from
experimental to production.
1. Foundation types — DataType, Layout, Args, Ops (#7114)
2. **This PR** — Schema engine (graph resolution)
3. Spec factories — GemmSpec, makeSpec() (#7180 )

Note: We also removed `FmhaBwdOp` for clarity, since that was introduced
early and doesn't have tests set up.

**Depends on**: #7114

## Test plan

- [x] ctest --test-dir build --output-on-failure — unit tests +
compile-fail tests pass
- [x] Compile-fail tests correctly reject: mixed CDNA+RDNA TargetSet,
conflicting layouts, empty quantization scale names

74bc86240b [rocm-libraries] ROCm/rocm-libraries#5647 (commit 490437a)
[CK Tile] Add gemm universal preshuffle to MX GEMM  (#5647)

## Motivation

Add gemm universal preshuffle support to existing MX GEMM pipeline.

The straightforward way to do this is to port the `mx_flatmm` pipeline
to the existing `gemm_mx` framework.

## Technical Details

The `mx_flatmm` pipeline was not deleted, to allow for
back-compatibility.

## Test Plan

Add `preshuffle` option to example: `tile_example_mx_gemm`.

Add new configurations with enabled preshuffle to the existing
`test/ck_tile/gemm_mx` tests.

## Test Result

Example and tests were successful on `gf950` architecture in the `Alola`
cluster.

fc2862d712 [rocm-libraries] ROCm/rocm-libraries#6846 (commit 377def4)
[CK_TILE] Add fmha forward hdim 256 support (#6846)

## Motivation

Enable Composable Kernel FMHA forward kernel for **hdim=256 BF16** on
AMD gfx950 (MI350X). Prior to this change the (256, 256) head-dim
configuration either failed to compile, was filtered out by the
compatibility rules, or produced incorrect kernel output due to an LDS
layout accounting bug.

## Technical Details

  Four files changed, all to enable hdim=256 BF16 on gfx950.

- **`fmha_fwd.py`** — Allow `(256, 256)` in gfx950 compatibility rule;
set `(256,256)` BF16 tile to `M0=128, N0=64` (the LDS-feasible shape on
gfx950); emit minimal valid instance set for d=256 to bound compile
time.

- **`fmha_fwd_kernel.hpp`** — Gate Prefill launch path off for d=256
(`PrefillCase = kM0 > 64 && kQKHeaddim < 256`); the double-buffer
Prefill variant overflows the 160 KB LDS budget.

- **`trload_policy.hpp`** — **Critical correctness fix**: the LDS layout
accounting in `GetSmemSize` was wrong (`max(Q, K+S+V)` instead of
`max(Q, K) + V + S`), under-allocating LDS and silently corrupting d=256
output (~2% wrong values).

- **`trload.hpp`** — Thread `LoadOnce=true` through all d=256 K-LDS
descriptors so the compiler picks the matching XOR swizzle period;
recompute the S-tile LDS offset to match the corrected `GetSmemSize`
formula.

## Test Plan

Built and ran `tile_example_fmha_fwd` on gfx950 (MI350X) with the
canonical d=256 BF16 configurations:

  ```bash
  cd build && ninja tile_example_fmha_fwd
./bin/tile_example_fmha_fwd -prec=bf16 -d=256 -d_v=256 -b=1 -h=32 -h_k=2
-s=1024 -s_k=1024 -bias=n -mask=t -lse=0 -p_drop=0 -warmup=3 -repeat=10

./bin/tile_example_fmha_fwd -prec=bf16 -d=256 -d_v=256 -b=8 -h=32 -h_k=2
-s=16384 -s_k=16384 -bias=n -mask=t -lse=0 -p_drop=0 -warmup=3
-repeat=10 -kname=1 -v=1
  ```

## Test Result

5ff7497fa7 [rocm-libraries] ROCm/rocm-libraries#7537 (commit 07123f4)
[CK Tile] Fix Grouped Gemm quant mixed precision (#7537)

<Migrate from Internal repo PR>
test_ck_tile_grouped_gemm_quant_tensor would fail for mixed FP8/BF8
cases:
std::tuple<Row, Col, Row, FP8, F32, BF8, F32, F32, F16, TensorQuant,
False, True, False>,
std::tuple<Row, Col, Row, BF8, F32, FP8, F32, F32, F16, TensorQuant,
False, True, False>

GFX1250 would fail with incorrect results, GFX950 would fail when
compiling BF8+FP8 and give incorrect results for FP8+BF8.
The issue is due to the wrong ComputeDataType selection.
The fix is to consider original ADataType and BDataType even when
ComputeDataType is not void. For compiling error on gfx950, the bf8,
fp8, 16x16x32 warp Gemm is added.

309d823056 [rocm-libraries] ROCm/rocm-libraries#7466 (commit cc2861f)
[CK Tile] Enable hardware OOB buffer load offset trick by default (#7466)

## Summary

Enables `CK_TILE_EXPERIMENTAL_USE_BUFFER_LOAD_OOB_CHECK_OFFSET_TRICK`
inside `config.hpp`.

  ### Background

When loading from global memory with out-of-bound (OOB) check, CK Tile
must suppress invalid lanes. The previous default used a software
branch:

  ```cpp
  // Old path (oob_conditional_check, no trick)
  if(!src_thread_element_valid) { return zeros; }
      return amd_buffer_load_impl(...);
```

  This generates divergent control flow, the compiler emits exec-mask save/restore and per-lane comparison SALU instructions one set per buffer load that touches a padded dimension.

  ### Change

  With the trick enabled, invalid lanes are suppressed entirely in hardware:
```cpp
  // New path (trick enabled)
uint32_t shift = src_thread_element_valid ? 0 : 0x80000000;
return amd_buffer_load_impl(resource, shift + offset, 0);
```
  The `0x80000000` offset overflows the buffer descriptor's declared size, causing the hardware to silently return zero for that lane - no branch, no exec mask manipulation. This matches the behavior of old CK XDL kernels, which use an unconditional load followed by a `v_cndmask` select.

  ### Expected impact

  Eliminates ALU overhead from OOB validity branches which reduces the kernel execution time, especially for memory-bound cases.

9cf49cd322 [rocm-libraries] ROCm/rocm-libraries#7465 (commit 81f1cf0)
[CK TILE] Increase default kPerXdl for grouped convolution instances  (#7465)

## Summary
Increases the default `kPerXdl` used in CK Tile grouped convolution
instance generation for forward, backward-data, and backward-weight
operations.
### Changes in `generate_instances.py`
- **Larger default `kPerXdl` for all fp16/bf16 tile sizes**:
`get_k_mfma()` now
returns `32` for `m/nPerXdl = 16` and `16` for `m/nPerXdl = 32`.
- **Cap `kPerXdl` to `kPerBlock`**: All three parsers
(`parse_fwd_instances`, `parse_bwd_weight_instances`,
`parse_bwd_data_instances`) now clamp the computed value with `min(...,
k_per_block)` to prevent generating invalid instances where `kPerXdl >
kPerBlock`.
### Expected impact
Higher `kPerXdl` increases the number of MFMA instructions issued per
warp per inner-loop iteration, improving arithmetic intensity and
reducing pipeline stall overhead for memory-bound shapes.

e7798e9560 [rocm-libraries] ROCm/rocm-libraries#7112 (commit a6e5eac)
Add asynchronous XOR shuffle support to the Async GEMM pipeline and the MX GEMM pipeline (#7112)

## Motivation

The goal of this work is to apply XOR shuffle (swizzle) to the current
`comp_async` GEMM pipeline and the `gemm_mx` pipeline.
XOR swizzling has been helpful to avoid LDS bank conflicts, as data are
redistributed across LDS banks, such that simultaneous threads accessing
different rows land on different LDS banks.

## Technical Details

A similar approach to the work in the existing eight-waves pipeline was
followed.
Currently, XOR swizzle support is available for FP8 and BF8 types.
FP4 support is also available for MX GEMM.
Should the types not match, or should the async vector width be of an
unsupported size, then the pipeline falls through to the previously
existing ('unswizzled') path.

## Test Plan

Execute `test_ck_tile_gemm_pipeline_comp_async` for the Async GEMM
pipeline.
Execute `test_ck_tile_mx_gemm_fp8` and `test_ck_tile_mx_gemm_fp4` for
the MX GEMM pipeline.

## Test Result

The tests passed successfully in the `Alola` cluster with MI350
hardware.

720ceb6500 [rocm-libraries] ROCm/rocm-libraries#7528 (commit b4cae6f)
[CK Tile] Support multi-vector reads in static encoding patterns  (#7528)

## Motivation

The thread-raked / warp-raked / block-raked static tile distribution
patterns in `ck_tile` silently produce wrong results when the contiguous
tile dimension is larger than `warp_size * vector_size`, because the
encoding has no per-thread iteration dimension along X.

Concretely, with `M_Tile=N_Tile=128`, `VectorSize{A,B,C}=1` in
`ConvConfigComputeV3`, the grouped convolution backward-weight example
reports about 50 percent wrong values, with errors starting exactly at
the `X0*X1 = 64` boundary. The second pass over the contiguous dim is
never performed.

This PR extends the encoding so multi-vector reads in the contiguous
tile dimension are supported, while keeping every existing call site
bit-for-bit identical.

## Technical Details

Three files changed.

### 1. `include/ck_tile/core/algorithm/static_encoding_pattern.hpp`

Add a per-thread X iteration dimension in all three raked
specializations:

- `X0 = min(warp_size, XPerTile / X1)` — threads in X dim
- `X1 = min(LargestVec, VecSize)` — vector size per access
- `X2 = XPerTile / (X0 * X1)` — number of X-iters per thread (new)

`X2` is gated with `if constexpr (X2 == 1) { old } else { new }` in both
`make_2d_static_tile_distribution()` and
`make_shuffled_2d_static_tile_distribution()`.

The new encoding places `X2` in the middle of the Ys iteration list,
which preserves reverse symmetry between the regular `<..., X2, X1>` and
shuffled `<X1, X2, ...>` encodings.

Patterns updated: `thread_raked`, `warp_raked`, `block_raked`.

### 2. `include/ck_tile/core/tensor/transpose_tile.hpp`

Added a parallel `else if constexpr (... && NDimY == 3 && ...)` branch
alongside the existing `NDimY == 2` branch. The original branch is
byte-for-byte unchanged.

Both branches dispatch to the same `transpose_tile2d_impl_in_thread`,
whose body has always been NDimY-generic (iterates with `static_for<0,
NDimY, 1>` and `number<NDimY>{}`).

### 3.
`experimental/grouped_convolution_tile_instances/generate_instances.py`

Removed the two now-obsolete skip guards in `parse_bwd_weight_instances`
and `parse_bwd_data_instances`:

```python
if m_per_block > (warp_size * a_scalar_per_vector) or n_per_block > (warp_size * b_scalar_per_vector):
    print(f"Skipping instance {instance_id} with multiple warps per continous tile dim since it's not supported yet.")
    continue
```

Other unrelated skips (V5 / V6 / ASYNC_V4 pipeline gating,
irregular-load shapes, scalar-per-vector > tile size) are kept
untouched.

### Compatibility

Strict. Every existing caller has `X2 == 1` and therefore hits the
original encoding path verbatim. No upstream config or pipeline behavior
changes.

## Test Plan

The grouped convolution example is the natural exerciser since
`GroupedConvUniversalPipelineAgBgCrPolicy` selects `thread_raked` for
both A and B tiles, and all three conv directions share the same
`ConvConfigComputeV3`.

For each test below we ran:

```
./build/bin/tile_example_grouped_conv_bwd_weight [-prec={fp16,bf16}]
./build/bin/tile_example_grouped_conv_fwd        [-prec={fp16,bf16}]
./build/bin/tile_example_grouped_conv_bwd_data   [-prec={fp16,bf16}]
```

with `ConvConfigComputeV3` tile/vector parameters tweaked to cover both
code paths:

| Test | M / N / K | VecA/B/C | A path | B path | dtype |

|------|-------------|----------|------------|----------------|-------------|
| T1 | 16/64/32 | 4/8/4 | old (X2=1) | old (X2=1) | fp16 |
| T2 | 128/128/64 | 2/2/2 | old (X2=1) | old (X2=1) | fp16 |
| T3 | 256/256/64 | 1/1/1 | old (X2=1) | new (X2=4) | fp16 |
| T5 | 256/256/64 | 1/1/1 | old (X2=1) | new (X2=4) | fp16 (3 dir)|
| T4b | 128/128/128 | 1/1/1 | new (X2=2) | new (X2=2) | fp16 + bf16 (3
dir) |

A larger T4a (256/256/128) was attempted to stress both A and B with
X2>1 on bigger tiles but was blocked by the gfx942 hardware LDS cap (128
KB > 64 KB limit), independent of this PR.

For the generator change we ran:

```
python3 generate_instances.py --mode profiler --direction all
```

and verified `Skipping instance ... with multiple warps per continous
tile dim` no longer appears (count went from non-zero to 0); other skip
categories are unchanged.

`clang-format-18` was applied to both modified `.hpp` files (matches the
repo's `.clang-format`).

## Test Result

- T1 and T2 (compat-strict, every X2 is 1, old code path): `correct`.
Confirms existing callers are unaffected.
- T3 (X2=4 on B only): `correct`. First true exercise of the new NDimY=3
encoding + transpose branch.
- T5 (T3 across `fwd` + `bwd_data` + `bwd_weight`, fp16): all 3
`correct`.
- T4b (X2>1 on both A and B, fp16 + bf16, all 3 directions): all 6 runs
`correct`.
- Generator: 0 `multiple warps per continous tile dim` skips remaining;
other skips unchanged.

Sample run output (T4b, bf16, bwd_data):

[CK Tile][MFMA/WMMA unification] Add support for packed datatypes (tiny types) (#6088)

## Motivation
This MR makes all the changes required for the unified architecture to
be able to deal with packed datatypes i.e. int4, fp4, fp6, and bf6. The
crux is that layout parameters should be interpreted as describing the
pure mathematical matrix fragments, while the ext_vectors and tile
distribution encodings describe everything in terms of packed datatype
units. This matches how packed types are dealt with in ck_tile and
should play nicely with the load and store tile ops once we integrate
the unified framework into CK tile.

The bf6 datatype was added to CK tile in the form of pk_bf6x16_t and
pk_bf6x32_t, which did not exist before.

The ext_vector implementations of pk_fp6x16_t and pk_bf6x16_t (vec size
1 and 2) were extended to make the subscripting operator work as
expected.

The layout test was adapted to be compatible with all packed datatypes,
and all new intrinsics were added to the test.

This MR adds ALL intrinsics across ALL architectures which use packed
datatypes, as well as ALL scale intrinsics:

## Testing
All intrinsics were tested on all architectures.

458dd0ac4c [rocm-libraries] ROCm/rocm-libraries#7130 (commit 9e1e065)
[CK_TILE] Redesign LDS store API with pre-computed window coordinates (+15% MI355X, +6% MI300X) (#7130)

## Summary

- Redesign the LDS store API to separate window creation from memory
transfer
- Add `MakeDistributedLdsStoreWindow` factory, `LocalStore` (fast path),
and `LocalStoreWithCoordRecompute` (slow path) to the pipeline base
class
- Convert CompV3 as the reference implementation
- Document the slow/fast path distinction across core tensor headers

## Motivation

`LocalPrefill` hides a performance cliff: when given a bare
`tile_window_with_static_lengths`, it silently reconstructs
`tile_window_with_static_distribution` on every call — paying
significant VALU overhead (~96 for typical configurations) for XOR
coordinate computation. The cost is invisible at the call site.

The new API makes the cost explicit via three verbs:

| Verb | Method | Cost | When to use |
|------|--------|------|-------------|
| **Create** | `MakeDistributedLdsStoreWindow(bare, dstr)` | VALU (once)
| Before hot loop, when VGPR budget allows |
| **Store (fast)** | `LocalStore(precomputed_window, tensor)` | 0 VALU
for coords | Pre-computed window available |
| **Store (on-the-fly)** | `LocalStoreWithCoordRecompute(bare, tensor)`
| VALU per call | VGPR budget tight, or one-shot stores |

Both `LocalStore` and `LocalStoreWithCoordRecompute` enforce correct
window types via `static_assert`. `LocalPrefill` is retained for
backward compatibility (69 call sites across 6 pipeline files).

## Performance

### 86 Shapes, CompV3_2 (128×128 tile), fp16, RCR layout

**gfx942 (MI300X): 86/86 improved, 0 regressions. Average gain: +6.2%**
**gfx950 (MI355X): 85/86 improved, 1 neutral, 0 regressions. Average
gain: ~+15%**

| **VMEM instructions** | 520,996 | 520,996 | **0%** |

MFMA as fraction of total instructions: **30.7% → 67.5%**. Eliminating
~3.65M redundant INT32 VALU instructions (XOR coordinate recomputation
per K-iteration) leaves the scheduler more headroom for MFMA dispatch,
directly explaining the benchmark gains.

[CK Tile] Eight Waves pipeline for MX GEMM (#5552)

## Motivation

Integrate Eight Waves pipeline in MX GEMM

## Technical Details

 - EightWaves pipeline:
- Add pipeline, policy and block gemm (internally using existing
implementation used by GEMM and ABQuant)
   - Extend support of EightWaves policy for FP4 (packed types)
 - Async pipeline:
- Fix pipeline with packed scales (requires MRepeat and NRepeat to be
contiguous)
- block gemm specific for MX GEMM is defined because distribution
encodings have changed
 - CShuffle:
- Add new functionality to support MRepeat and NRepeat contiguous
(defined by `TilesPacked`)
 - Examples:
- Refactor examples to easily switch different configurations (similar
to GEMM universal)
- Scales values generated consistently with other microscale
implementations in CK Tile
   - Add configuration for EightWaves pipeline
 - Tests:
   - Unify existing FP8 and FP4 tests
   - Add tests for EightWaves pipeline
- Scales values generated consistently with other microscale
implementations in CK Tile

Note: FP6 support for MX GEMM was added later and the support for the
Eight Waves pipeline will be done in following PR

## Test Plan

Add new pipeline to tests: `test_ck_tile_mx_gemm_async` for both FP4 and
FP8

[CK] Fix FMHA sink dispatch when init_sink_value is set (#7530)

## Summary
- Fix `traits.has_sink` in `fmha_fwd_runner.hpp` to also check
`init_sink_value != 0`, so the GPU kernel dispatches with sink support
when `-init_sink=1` is passed.
- Gate `run_sink_mask_tests` (StreamLLM) and `run_sink_init_tests`
(GPT-OSS) behind opt-in flags `-m` and `-g` in `smoke_test_fwd.sh`.
These tests require sink=true kernel instances which are excluded by the
`BUILD_TESTING` CMake filter (`*_nsink*`), causing unconditional "not
supported yet" failures (48 tests in CI). The opt-in flag approach was
borrowed from PR #6057.

## Why gate tests instead of compiling sink=true kernels?

The `BUILD_TESTING` filter in `CMakeLists.txt` uses `*_nsink*` glob
patterns for the `fwd` and `fwd_splitkv` APIs, excluding sink=true
kernel instances from compilation. We chose opt-in flags over widening
the filter because:

- **Compile time**: Enabling sink=true kernels doubles the kernel
variants for `fwd` and `fwd_splitkv` APIs. The filter exists
specifically to reduce CI build times.
- **Incremental enablement**: Sink support (StreamLLM / GPT-OSS) is
still maturing. Gating lets teams opt in explicitly (`smoke_test_fwd.sh
-g`) while keeping the default CI path fast.
- **Precedent**: splitkv (`-s`) and appendkv (`-a`) tests already follow
this opt-in pattern.

## Test plan
- [ ] Run `smoke_test_fwd.sh -g` with sink=true kernels compiled and
verify sink-enabled kernels are dispatched
- [ ] Verify `smoke_test_fwd.sh` still passes without `-m` / `-g` flags
- [ ] Confirm CI no longer fails on sink tests (they are now opt-in)

[CK Conv] Wavelet gemm pipeline for bwd_weight convolution (#5652)

## Motivation

In the current CShuffleV3 backward weight kernel, the in-kernel
conv-to-GEMM transform generates significant INT32 VALU pressure per
MFMA instruction. On VALU-heavy shapes (e.g., G=1, 3×3, C=256), these
index computation ops compete with MFMA for VALU issue slots, creating a
bottleneck that cannot be resolved by pipeline prefetching alone.

This PR adds a wave-specialized ("wavelet") convolution backward weight
kernel that splits workgroup threads into two roles:
- **Load waves**: conv-to-GEMM address computation + global memory loads
+ LDS writes (all VALU/VMEM)
- **Math waves**: LDS reads + MFMA + CShuffle epilogue (no index
computation)

By physically separating the two instruction classes onto different
waves, VALU and MFMA execute on different hardware functional units
without contention.

## Technical Details

**Core kernel (new files):**
- `gridwise_gemm_xdl_waveletmodel_cshuffle_conv_v3.hpp` —
wave-specialized gridwise GEMM for conv bwd weight (2-way split: load +
math)
- `device_grouped_conv_bwd_weight_xdl_waveletmodel_cshuffle_v3.hpp` —
device op following CShuffleV3 patterns; `BlockSize =
TileMathThreadGroupSize` for MFMA wave assignment, `LaunchBlockSize =
TileLoad + TileMath` for kernel launch

**Wave pipeline (modified):**
- `gridwise_gemm_waveletmodel.hpp` — load/math wave pipeline structs
with `sched_group_barrier` scheduling hints to front-load VMEM reads
before address-advance VALU

**Two wave ratios:**
- **(4,4)**: 256 load + 256 math = 512 threads (8 waves). Best on large
shapes.
- **(4,2)**: 256 load + 128 math = 384 threads (6 waves). Best on small
shapes (fewer sync barriers, denser MFMA per math wave).

**Instance coverage (F16 and BF16 symmetric):**

| Ratio | Tiles | Layouts | ConvSpecs |
|-------|-------|---------|-----------|
| (4,4) | M128×N128, M64×N64, M128×N64, M64×N128 | 2D NHWGC, 3D NDHWGC |
Default, Filter1x1Stride1Pad0 |
| (4,2) | M64×N64, M128×N64, M64×N128 | 2D NHWGC | Default,
Filter1x1Stride1Pad0 |

**Existing wavelet model fixes:**
- `BlockSize` corrected from `math::max(TileLoad, TileMath)` to
`TileMathThreadGroupSize` in the flat-GEMM wavelet device op and
gridwise kernel

## Test Plan

- `test_grouped_convnd_bwd_weight` GTest: 34 hardcoded test cases
covering 1D/2D/3D, F16/BF16, G=1/2/16, various spatial sizes
- Performance benchmark: all 37 RetinaNet bwd_weight shapes on gfx950

```bash
ninja -C build test_grouped_convnd_bwd_weight
./build/bin/test_grouped_convnd_bwd_weight
```

## Test Result

**Correctness:** 34/34 GTest cases passed (F16/BF16 × 1D/2D/3D ×
Default/Filter1x1Stride1Pad0 × various G/N/K/C combinations).

**Performance:** Wavelet is the fastest overall instance on 12/37
RetinaNet shapes — all G=1, 3×3 convolutions with C=256 (the VALU-heavy
target shapes):

| Shape | Uplift vs best baseline |
|-------|------------------------|
| K=36, 7×7 | 1.91x |
| K=36, 100×100 | 1.60x |
| K=36, 13×13 | 1.43x |
| K=36, 25×25 | 1.38x |
| K=36, 50×50 | 1.38x |
| K=256, 100×100 | 1.24x |
| K=256, 13×13, s=2 | 1.20x |
| K=256, 25×25, s=2 | 1.20x |
| K=256, 7×7 | 1.17x |
| K=256, 13×13 | 1.13x |
| K=2376, 50×50 | 1.05x |
| K=2376, 100×100 | 1.06x |

Where wavelet does not win (25/37): 1×1 convolutions (explicit kernel
does host-side transform), grouped convolutions with small per-group
channels, and shapes where standard CShuffleV3 already amortizes VALU
overhead.

[CK] Enable grouped conv bwd data to match non-grouped perf via NoShuffle + packed descriptors (#6208)

## Motivation

Improve performance of grouped convolution backward-data kernels to
match non-grouped kernel performance for G=1 cases.

## Technical Details

- Add NoShuffle epilogue path (direct VGPR→Global writes) by setting
`CDEBlockTransferScalarPerVector_NPerBlock = 1`
- Add nongrouped-match instances with optimized BBlockTransfer
parameters for better thread utilization
- Add packed (flat) descriptor path for G=1 2D convolutions, using
simpler tensor descriptors with fewer transform layers to reduce address
computation overhead in the GEMM main loop
- Cherry-pick PR #6090 for fair benchmarking (cache flush, include dX
zeroing cost)

## Test Plan

- Benchmark grouped vs non-grouped kernels on MI300X (589 shapes, BF16)
- Verify correctness with existing conv bwd data tests

## Test Result

| Metric | Before | After |
|--------|--------|-------|
| Mean ratio (grouped/nongrouped) | 1.159 | **1.028** |
| Median ratio | 1.142 | **1.026** |
| Cases within 2% | 26 (4.4%) | **186 (31.8%)** |
| Cases >20% slower | 188 (32%) | **2 (0.3%)** |

NoShuffle + nongrouped-match instances achieve **~2.8% average gap**
with non-grouped kernels (down from ~16%).

[CK TILE] Unification Work – Add `print()` Utility to `MmaOpTraits` (#6207)

## Motivation

It would be useful to have a `print()` utility inside of unification
work's code scope, so that we can print all template params and derived
params of `amdgcn_mma` for easier debugging.

## Technical Details

Adding helper functions and struct to traits, adding `print_flags()` for
each `Default*CtrlFlags`, `amdgcn_target` and `MmaOpTraits` structs, and
adding `print()` for `amdgcn_mma`.

Note: the first commit is **not** in the scope of this PR. This PR
should be merged after https://github.com/ROCm/rocm-libraries/pull/5801
and https://github.com/ROCm/rocm-libraries/pull/5857.

## Test Plan

Adding test in layout test.

## Test Result

Test should pass.

[CK] [CK_Tile] Add FMHA scaffolding to CK kernel dispatcher (#5260)

## Motivation

The CK Tile dispatcher currently supports GEMM and Grouped Convolution
but has no support for Fused Multi-Head Attention (FMHA). The
example/ck_tile/01_fmha folder contains a comprehensive FMHA
implementation with forward, backward, split-KV, paged-KV, append-KV,
and batch-prefill kernels across multiple GPU architectures — but there
is no unified dispatch layer for it. This PR ports the FMHA stack into
the dispatcher, following the same architectural patterns established by
GEMM and Grouped Convolution, enabling runtime kernel selection, JIT
compilation from Python, and a declarative C++ example flow. Autotuning
heuristics to follow.

## Technical Details

This PR adds FMHA scaffolding to the CK dispatcher framework, mirroring
GEMM's layered architecture. Seven new C++ runtime headers provide type
definitions (coexisting with upstream headers via __has_include,
requiring zero modifications to example/ck_tile/01_fmha/), a problem
builder with 18+ setters, Signature + Algorithm kernel key matching, a
virtual kernel instance, a DECL_FMHA_KERNEL_SET macro with wildcard
support and named tile/wave/warp setters, arch-aware registry with JSON
export, and a dispatcher with seqtune-aware selection, configurable
timing, and multi-stage execution plans for split-KV (two-stage) and
backward (three-stage). The codegen pipeline is driven by a
fmha_arch_specs.json capturing per-arch tile tables and pipeline
constraints for five architectures (gfx90a/942/950/1100/1201), migrated
from hardcoded logic in 01_fmha/codegen/, with supporting modules for
C++ symbol mappings, validation rules, and named receipt profiles
(ck_default, flash, pytorch, aiter, fp32, fp8). Python integration
(fmha_utils.py) mirrors the C++ layer with JIT compilation, parallel
multi-kernel builds, HIP memory management via ctypes, tolerance-based
validation, and a NumPy CPU reference with GQA support. Twenty-seven C++
and thirty-two Python examples cover the full feature surface — forward,
split-KV, masks, bias, dropout, GQA, backward, append-KV, batch prefill,
fp8, logits soft cap, sink tokens, and parameter sweeps — all
JIT-compiled on the fly.

## Test Plan

Seven test files cover the runtime types, codegen, and end-to-end
correctness. C++ unit tests validate the problem builder, dispatcher
planning (single-stage for forward/paged-KV/append-KV; multi-stage for
split-KV and backward), registry operations, and the kernel-set
declaration macro. Python unit tests verify codegen emission, profile
filtering, and 15 validation rules for masks, hdim constraints, and
pipeline requirements. GPU execution validation in 01_basic_fmha
--validate reports zero errors across 65,536 elements with max absolute
error of 7.29e-05. A gold-standard parity suite (test_fmha_parity.py)
runs 14 configurations through both the upstream tile_example_fmha_fwd
and the dispatcher, comparing exit codes to confirm behavioral parity —
all 14 match.

## Test Result

The C++ smoke test builds and passes all 9 compiled examples, and a
Python JIT sweep (29_sweep_seqlen.py) passes 7/7 configurations reaching
up to 375 TFLOPS at seqlen 2048.

[CK] fix some jenkins logic errors. (#7516)

## Motivation

After merge from internal repo got some logic errors in the internal CI
jenkinsfile.
Here are 2 fixes for 2 issues:
1. make sure .ninja_log file exists before trying to parse it
2. use the default compiler for the gfx1250 target, since it's getting
built in its own special docker, which does not have the option of
installing alternative compilers.

ffebf1215b [rocm-libraries] ROCm/rocm-libraries#7114 (commit ecef372)
[CK] Add rocm_ck foundation types: DataType, Layout, Args, Ops (#7114)

## Summary

- Add the vocabulary types that all rocm_ck schema headers build on
- 9 new headers under `include/rocm_ck/`, 6 unit test files
- Pure C++20, host-only — no CK Tile dependencies

**Headers:**

| Header | Purpose |
|--------|---------|
| `index_t.hpp` | `index_t`, `long_index_t` (matches ck_tile) |
| `gpu_target.hpp` | `GpuTarget` enum (ISA targets) |
| `datatype.hpp` | `DataType` enum (17 variants) |
| `layout.hpp` | `Layout` enum (Row, Col, Auto) + stride helpers |
| `fixed_string.hpp` | `FixedString<N>` — structural string for NTTPs |
| `args.hpp` | Generic kernel argument buffer (ABI) |
| `ops.hpp` | Operator structs (`GemmOp`, `AddOp`, ...) + `Op` variant |
| `physical_tensor.hpp` | `PhysicalTensor` — maps names to Args slots |
| `resolved_tensor.hpp` | `ResolvedTensor` — output of
`Signature::resolve()` |

**Stack**: This is PR 1 of 3 porting the rocm_ck constexpr schema from
experimental to production, #7143.
1. **This PR** — Foundation types (vocabulary)
2. Schema engine — `Signature`, `resolve()`, `ArchProperties`
3. Spec factories — `GemmSpec`, `ElementwiseSpec`, `makeSpec()`

## Test plan

- [ ] `ninja build-smoke-rocm-ck` builds all tests
- [ ] `ctest -L ROCM_CK_SMOKE --output-on-failure` — 6 unit tests pass
(86 test cases)
- [ ] Default CK build (`CK_ENABLE_ROCM_CK=OFF`) unaffected

067e5e0ca4 [rocm-libraries] ROCm/rocm-libraries#6838 (commit ff7a665)
[CK_TILE] Add depthwise conv2d forward kernel (FP16/FP32) (#6838)

## Motivation

CK currently has no kernel optimized for depthwise convolution
(G=C_in=C_out, C=K=1 per group) and existing generic paths perform
poorly for this workload. This PR adds a dedicated depthwise conv
forward kernel in CK Tile.

## Technical Details

Adds a dedicated depthwise conv2d forward op to CK Tile that performs
direct convolution rather than falling back to the generic GEMM path.
The kernel is templatized by filter size, stride, and data type, and
compiled into ~60 instances covering common configurations (kernel
3/5/7/9, stride 1/2, FP16/FP32). Supports both CDNA (gfx942/gfx950) and
RDNA (gfx1100/gfx1200) architectures.

## Test Plan

- [x] Correctness and performance validated on gfx942, gfx950, and
gfx1100, with ckProfiler `grouped_conv_fwd` as baseline.
- [ ] MI300A (gfx942) and gfx1200 validation.
