Subject: [PATCH 0/3] [RFC] kernel cpu access support for dma_buf
Date: Thu,  1 Mar 2012 16:35:58 +0100	[thread overview]
Message-ID: <1330616161-1937-1-git-send-email-daniel.vetter@ffwll.ch> (raw)

Hi all,

This series here implements an interface to enable cpu access from the kernel
context to dma_buf objects. The main design goal of this interface proposal is
to enable buffer objects that reside in highmem.

Comments, flames, ideas and questions highly welcome. Althouhg I might be a bit
slow in responding - I'm on conferences and vacation the next 2 weeks.

Cheers, Daniel

  dma-buf: don't hold the mutex around map/unmap calls
  dma-buf: add support for kernel cpu access
  dma_buf: Add documentation for the new cpu access support
