Each +instance knows whether it refers to system or I/O memory. Most of the DRM-wide +interface have been converted to use struct dma_buf_map, but implementations +often still use raw pointers. + +The task is to use struct dma_buf_map where it makes sense. + +* Memory managers should use struct dma_buf_map for dma-buf-imported buffers. +* TTM might benefit from using struct dma_buf_map internally. +* Framebuffer copying and blitting helpers should operate on struct dma_buf_map. + +Contact: Thomas Zimmermann <tzimmermann@suse.de>, Christian König, Daniel Vetter + +Level: Intermediate + Core refactorings ================= |
