Hi Laurent,
You make this very clear, thank you!
The ISP on Medfield do have its own IOMMU. And I also think an IOMMU layer
for ISP is needed.
I'm not quite understand unless hardware design doesn't give you a choice

Hi Hans,
Thanks for your point and videobuf2 is also what I want to use.
But since our development kernel version right now is still 2.6.35, I
need to find way to work with current videobuf framework.

Hi,
We are developing the image processor driver for Intel Medfield platform.
We have received some comments on memory management that we should use
standard Linux kernel interfaces for this, since we are doing everything by

Curious for the below, why it is a sum? Will you use all of format at the same
time?
1 RAW16: 2*14 = 28MB
1 qplane6: 6/4 * 14 = 21MB
1 yuv420_16: 2 * 1.5 * 14 = 42MB
1 yuv420: 1.5 * 14 = 21MB
1 yuv444: 3 * 14 = 42MB
total: 154MB.

Yes. Some are internal frame and yuv444 is the output.
