[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:
