Subject: Claude review: drm/gpuvm: Add a helper to check if two VA can be merged
Date: Sat, 14 Mar 2026 06:48:45 +1000 [thread overview]
Message-ID: <review-patch4-20260313150956.1618635-5-adrian.larumbe@collabora.com> (raw)
In-Reply-To: <20260313150956.1618635-5-adrian.larumbe@collabora.com>
Patch Review
The `can_merge()` helper consolidates scattered merge checks into one function. The logic looks correct:
- Same GEM object required, must be non-NULL
- VAs must be contiguous/overlapping (WARN_ON if gap)
- VA diff must match GEM offset diff for merge eligibility
One minor style note: the comment style uses `/* ... */` block comments which is fine but inconsistent -- some start with `/*` on the same line as text. Kernel style typically has `/*` on its own line for multi-line comments.
The removal of the inline merge checks in `__drm_gpuvm_sm_map()` is clean and the replacement with `can_merge(gpuvm, va, &req->map)` is correct.
