[PATCH 00/40] media: atomisp: Various hmm and other cleanups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I want to start writing a libcamera pipeline handler for the atomisp2,
but before I can do that I first need to fix mmap support in  atomisp2.

My plan for this is to port the atomisp2 handler to videobuf2. To do that
I first need to understand the existing memory/buffer management so I've
started with cleaning up the hmm code (with a bit of a detour here and
there).

This series is the result of that. There are likely more cleanups to
follow, but I've to focus on some other things for a bit. I hope to be
able to return to the cleanups + an eventual videobuf2 conversion soon.

Regards,

Hans
