- * DOC: cma helpers
- *
- * The DRM GEM/CMA helpers are a means to provide buffer objects that are
- * presented to the device as a contiguous chunk of memory. This is useful
- * for devices that do not support scatter-gather DMA (either directly or
- * by using an intimately attached IOMMU).
- *
- * Despite the name, the DRM GEM/CMA helpers are not hardwired to use the
- * Contiguous Memory Allocator (CMA).
- *
- * For devices that access the memory bus through an (external) IOMMU then
- * the buffer objects are allocated using a traditional page-based
- * allocator and may be scattered through physical memory. However they
- * are contiguous in the IOVA space so appear contiguous to devices using
- * them.
- *
- * For other devices then the helpers rely on CMA to provide buffer
- * objects that are physically contiguous in memory.
- *
- * For GEM callback helpers in struct &drm_gem_object functions, see likewise
- * named functions with an _object_ infix (e.g., drm_gem_cma_object_vmap() wraps
- * drm_gem_cma_vmap()). These helpers perform the necessary type conversion.

+ * presented to the device as a contiguous chunk of memory. This is useful
+ * for devices that do not support scatter-gather DMA (either directly or
+ * by using an intimately attached IOMMU).
+ *
+ * For devices that access the memory bus through an (external) IOMMU then
+ * the buffer objects are allocated using a traditional page-based
+ * allocator and may be scattered through physical memory. However they
+ * are contiguous in the IOVA space so appear contiguous to devices using
+ * them.
+ *
+ * For other devices then the helpers rely on CMA to provide buffer
+ * objects that are physically contiguous in memory.
+ *
+ * For GEM callback helpers in struct &drm_gem_object functions, see likewise
+ * named functions with an _object_ infix (e.g., drm_gem_dma_object_vmap() wraps
+ * drm_gem_dma_vmap()). These helpers perform the necessary type conversion.
