I know this pain :-(

Laurent - do you have a solution for people to reply to mails they have
not received for the libcamera list? (That doesn't involve requiring
everyone to get every mail on the list?) I think the only solution there
is for us to set up public inbox ... but I don't have any time to look
at such topics lately.

I agree there ;-)

Excellent! I think the caching issues will still be prevalent. I wonder
if we can handle that in the simple pipeline handlers by using the
dma-heap allocator for the frame buffers instead of getting buffers from
V4L2, particularly as this series helps provide access to the dma-heap
allocators.
