Subject: Claude review: drm/gem-dma: Support dedicated DMA device for allocation and mapping
Date: Wed, 11 Mar 2026 13:48:35 +1000 [thread overview]
Message-ID: <review-patch2-20260310032012.2542334-3-wenst@chromium.org> (raw)
In-Reply-To: <20260310032012.2542334-3-wenst@chromium.org>
Patch Review
Mechanically replaces all `drm->dev` / `gem_obj->dev->dev` with `drm_dev_dma_dev(drm)` / `drm_dev_dma_dev(gem_obj->dev)` in the GEM DMA helper for allocation, free, sgtable, and mmap paths.
The changes are consistent and complete -- all DMA API calls in `drm_gem_dma_helper.c` now go through `drm_dev_dma_dev()`:
- `dma_alloc_noncoherent()` / `dma_alloc_wc()` in `drm_gem_dma_create()`
- `dma_free_noncoherent()` / `dma_free_wc()` in `drm_gem_dma_free()`
- `dma_get_sgtable()` in `drm_gem_dma_get_sg_table()`
- `dma_mmap_pages()` / `dma_mmap_wc()` in `drm_gem_dma_mmap()`
The commit message correctly notes no existing driver currently combines GEM DMA helpers with `drm_dev_set_dma_dev()`, so this is safe to land without immediate behavioral changes.
**Reviewed-by worthy**: Yes.
