Subject: Coherent DMA mapping for existing struct page
Date: Mon, 24 Jan 2011 15:26:37 -0500 [thread overview]
Message-ID: <87ipxevyiq.fsf@inspiron.ap.columbia.edu> (raw)
Hello,
How do I set up a coherent DMA mapping for an existing struct page?
dma_alloc_coherent() wants to allocate its own buffer, and
dma_map_page() sets up streaming mappings. Which function am I missing?
Thanks,
-Nikolaus
