• 36c0f8b32   [media] vb2: replace void *alloc_ctxs by struct device *alloc_devs ... Browse Code »

  Make this a proper typed array. Drop the old allocate context code since
  that is no longer used.

  Note that the memops functions now get a struct device pointer instead of
  the struct device ** that was there initially (actually a void pointer to
  a struct containing only a struct device pointer).

  This code is now a lot cleaner.

• c139990e8   [media] media: videobuf2: Replace videobuf2-core with videobuf2-v4l2 ... Browse Code »

  Make videobuf2-v4l2 as a wrapper of videobuf2-core for v4l2-use.
  And replace videobuf2-core.h with videobuf2-v4l2.h.
  This renaming change should be accompanied by the modifications
  of all device drivers that include videobuf2-core.h.
  It can be done with just running this shell script.

  replace()
  {
  str1=$1
  str2=$2
  dir=$3
  for file in $(find $dir -name *.h -o -name *.c -o -name Makefile)
  do
  echo $file
  sed "s/$str1/$str2/g" $file > $file.out
  mv $file.out $file
  done
  }

  replace "videobuf2-core" "videobuf2-v4l2" "include/media/"
  replace "videobuf2-core" "videobuf2-v4l2" "drivers/media/"
  replace "videobuf2-core" "videobuf2-v4l2" "drivers/usb/gadget/"
  replace "videobuf2-core" "videobuf2-v4l2" "drivers/staging/media/"

  Require that dma-sg also uses an allocation context. This is in preparation
  for adding prepare/finish memops to sync the memory between DMA and CPU.

  Replace the private struct vb2_dma_sg_desc with the struct sg_table so
  we can benefit from all the helping functions in lib/scatterlist.c for
  things like allocating the sg or compacting the descriptor.
  marvel-ccic and solo6x10 drivers, that use this API have been updated.

• 5ba3f757f   [media] v4l: videobuf2: add DMA scatter/gather allocator ... Browse Code »

  Add an implementation of DMA scatter/gather allocator and handling
  routines for videobuf2.

  For mmap operation mode it is implemented on top of
  alloc_page + sg_set_page/_free_page.

  For userptr operation mode it is implemented on top of
  get_user_pages + sg_set_page/put_page.
