Hello, This patch series implements support for dma_buf import in the omapdrm driver. The patches are based on top of the latest drm-next branch and can be found in my git tree at git://linuxtv.org/pinchartl/fbdev.git omapdrm/dmabuf-import The first two patches are unrelated fixes and enhancements, but I've included them in the series to avoid merge conflicts. The next 12 patches are miscellaneous fixes, cleanups and refactoring to prepare for patch 15/15 that implements dma_buf import. The code has been successfully tested with the vivid driver as an exporter, using a hacked version that uses uncached CPU mappings in vivid when filling the buffers. vivid is a test driver that generates a test pattern using the CPU with cached mappings by default, resulting in corruption on the screen due to missing cache handling. As the problem doesn't occur when sharing buffers not touched by the CPU or touched through uncached mappings only, it will be addressed separately.
