Subject: Claude review: drm/prime: Limit scatter list size with dedicated DMA device
Date: Thu, 12 Mar 2026 07:08:42 +1000 [thread overview]
Message-ID: <review-patch1-20260311094929.3393338-2-wenst@chromium.org> (raw)
In-Reply-To: <20260311094929.3393338-2-wenst@chromium.org>
Patch Review
A one-liner that changes `dev->dev` to `drm_dev_dma_dev(dev)` in `drm_prime_pages_to_sg()`:
```c
- max_segment = dma_max_mapping_size(dev->dev);
+ max_segment = dma_max_mapping_size(drm_dev_dma_dev(dev));
```
This is correct and straightforward. The existing code queries the DMA max mapping size from the parent device, but if a dedicated DMA device is set, the constraints of that device are the relevant ones. The `drm_dev_dma_dev()` helper gracefully falls back to `dev->dev` when no dedicated device is set, so this is safe for all existing users.
No issues.
