Hi,
I've checked this matter with a colleague and we have several reasons
to doubt that the i.MX27 and the i.MX53 can share the same driver for
their Video Processing Units (VPU):
1. The VPU in the i.MX27 is a codadx6 with support for H.264, H.263
and MPEG4-Part2 [1]. Provided Freescale is using

Hi Laurent and Subash,
I confirm the issue found by Subash. The function
vb2_dc_kaddr_to_pages does fail for some occasions.
The failures are rather strange like 'got 95 of
150 pages'. It took me some time to find the reason
of the problem.
I found that dma_alloc_coherent for iommu an ARM does

Hi Bhupesh,
Thanks for the patch.
As Felipe has already applied the patch to his public tree, I'll send
incremental cleanup patches. Here's my review nonetheless, with a question
which I'd like to know your opinion about to write the cleanup patches.

I think this is an approach worth investigating. I'd like a way to
either opt out of implicit sync or have a way to check if a dma-buf
has an attached fence and detach it. Actually, that could work really
well. Consider:
memweight() is the function that counts the total number of bits set
in memory area. Unlike bitmap_weight(), memweight() takes pointer
and size in bytes to specify a memory area which does not need to be
aligned to long-word boundary.
