[ck] Enforce ASCII-only C/C++ sources for hipRTC
compatibility (#7829)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
## Summary
CK source files must be compilable via **hipRTC (HIP runtime
compilation)**, whose preprocessor does not accept non-ASCII bytes
anywhere in a translation unit — **including in comments**. Bytes that
are harmless under `hipcc` (em-dashes, smart quotes, multiplication
signs, Greek letters, box-drawing glyphs, etc.) cause hipRTC to fail at
preprocessing time. These regularly leak in via LLM-assisted authoring
or copy/paste from formatted documents and silently break hipRTC paths
that are not exercised by the default `hipcc`-based build matrix.
This PR (a) cleans every existing violation (53 files) and (b) adds a
pre-checkin gate so new violations are rejected before merge.
## File extensions covered
Both the cleanup scan and the new Jenkins enforcement stage use the same
predicate:
```
*.h *.hpp *.cpp *.h.in *.hpp.in *.cpp.in *.inc *.cl
```
(excluding `*/build/*` and `*/include/rapidjson/*`). This is a strict
superset of the existing `Clang Format` stage's predicate — `*.inc` is
added so test-fixture include files are also gated. The local pre-commit
hook's `c++/inc` type filter covers the same set.
## Why no enforcement today
CK is opted out of the rocm-libraries root `.pre-commit-config.yaml`, so
the existing `pre-commit` workflow doesn't touch CK. The local CK
`.pre-commit-config.yaml` only runs for developers who installed hooks.
The **authoritative gate is therefore the new Jenkins stage** in this
PR; the local hook is convenience.
## Commit layout (bisect-friendly)
1. `79798aa6261` — **`[ck] Convert reflect/ rendering to ASCII for
hipRTC compatibility`**
Behavior change, isolated. `TreeFormatter` swaps `├─ / └─ / │ ` for `|-
/ +- / | ` (3-col width preserved so alignment is unchanged).
`conv_description.hpp` swaps `×` for `x` as the dimension separator.
`test_conv_description.cpp` expected strings updated in lockstep so the
snapshot test stays green. This is the only commit in the series with
observable runtime impact.
2. `738fdb0d81c` — **`[ck] Strip non-ASCII bytes from C++ sources for
hipRTC compatibility`**
Mechanical text cleanup across 53 files. Replacements happen in comments
or in `std::cout` strings that are not asserted on by any test. None of
the 174 `.inc` files in the tree required edits, but they were in the
scan's predicate so the enforcement stage's predicate is a superset of
what was scanned. Full replacement table in the commit message.
3. `1d7cd8ba235` — **`[ck] Enforce ASCII-only C/C++ sources for hipRTC
compatibility`**
- New `projects/composablekernel/script/check_ascii_only.sh` (modeled on
`check_copyright_year.sh`).
- New entry in `projects/composablekernel/.pre-commit-config.yaml` under
the local-hooks block (`types_or: [c++, inc]`).
- New `ASCII Only Check` parallel stage in
`projects/composablekernel/Jenkinsfile`'s `Static checks` block,
mirroring the existing `Clang Format` stage but with `*.inc` added to
the find predicate. Always-on, no `RUN_CPPCHECK` gate.
The tree is buildable at every commit boundary. Commit 1 leaves 50 known
violations; commit 2 leaves 0; commit 3 wires the gate.
## Demo
Script output on a synthesized violation:
```
$ printf '// em-dash test \xe2\x80\x94 here\n' > /tmp/bad.cpp
$ projects/composablekernel/script/check_ascii_only.sh /tmp/bad.cpp
ERROR: /tmp/bad.cpp contains non-ASCII bytes:
1:// em-dash test — here
Fix: replace with ASCII (em-dash -> --, smart quotes -> ", arrows -> ->, etc.)
$ echo $?
1
```
Full repo scan after the cleanup commits (note the `-name '*.inc'`
clause):
```
$ cd projects/composablekernel && find . -type f \( -name '*.h' -o -name '*.hpp' -o -name '*.cpp' \
-o -name '*.h.in' -o -name '*.hpp.in' -o -name '*.cpp.in' -o -name '*.inc' -o -name '*.cl' \) \
-not -path '*/build/*' -not -path '*/include/rapidjson/*' -print0 \
| xargs -0 -P 8 -n 64 script/check_ascii_only.sh
$ echo $?
0
```
## Test plan
- [ ] Jenkins PR build: confirm new `Static checks -> ASCII Only Check`
stage runs green over the full predicate (incl. `*.inc`) and existing
`Clang Format` stage is unaffected.
- [ ] `test_conv_description` passes against the ASCII tree-formatter
output (touched in commit 1).
- [ ] Local: `pre-commit run ascii-only-checker --all-files` runs
cleanly after installing CK pre-commit hooks via
`script/install_precommit.sh`.
- [ ] Manually inject a non-ASCII byte in any `.cpp/.hpp/.inc` file,
push: confirm Jenkins fails the new stage with a clear error.
- [ ] Spot-check a representative subset of touched files under hipRTC
compilation to confirm no remaining hipRTC-blocking content (optional,
since the static byte check is a sufficient condition for hipRTC
preprocessor acceptance on this dimension).

[CK_BUILDER] ck builder conv transfer fix (#4750)
## Motivation
This PR fixes how CK Builder is validating transfer vector size and adds
proper validation for LDS transfer vector size as well.
## Changes:
* [__source vector dim__] -- Before this PR the data transfer validation
logic didn't allow to set the source vectorized dimension to 1. However
there are CK instances that are doing this when the group merging is
used. This is used only for
`DeviceGroupedConvFwdMultipleABD_Xdl_CShuffle` kernel.
* [__valid vector size__] -- Before this PR the validation logic
concerned only single instruction maximum vector size. However our
buffer loading logic has implemented support for loading more values
through multiple buffer instructions. This again was discovered to be
used in some of the convolution instances. Thus this behavior was
reflected in validation logic.
* [__valid LDS vector size__] -- Before this PR the LDS vector size
validation was done in the same way as VMEM. This PR adds proper LDS
vector size validation based on the available LDS instruction sizes.
## Test Plan
Run CK BUILDER conv fwd factories tests
## Test Result
All CK BUILDER conv fwd factories work (except DL one & ck tile since
they're not yet added now)

[CK] Updated pre-commit entry points (#4649)
## Motivation
Pre-commit fails after the transition to the monorepo. This fixes it.
## Technical Details
-
## Test Plan
Try to commit on CK with pre-commit enabled.
## Test Result
Pre-commit should pass. (Scripts are correctly found)
