Hi all, The request has come up on OMAP4 to support non-page-aligned v4l2 buffers. (This is in context of v4l2 display, but the same reasons would apply for a camera.) For most common resolutions, this would help us get much better memory utilization for a range of memory (or rather address space) used for YUV buffers. However it would require a small change in the client application, since most (all) v4l2 apps that I have seen are assuming the offsets they are given to mmap are page aligned. I am curious if anyone has any suggestions about how to enable this. Ideally it would be some sort of opt-in feature to avoid breaking apps that are not aware the the offsets to mmap may not be page aligned.
