Hi All,
This series was written in parallel with reading and understanding the
vchiq code. So excuse me for the lack of logic in the sequence of
patches.
It's an RFC for various reasons, first I think it's going to clash with
the last Stefan's series. Also I'm not used to doing big series.
The main focus was to delete as much code as possible, I've counted
around 550 lines, which is not bad. Apart from that there are some
patches enforcing proper kernel APIs usage.
The only patch that really changes code is the
vchiq_ioc_copy_element_data() rewrite, I was having doubts whether to
add it into the series, but since it's a RFC, I don't think it hurts.
The last commit updates the TODO list with some of my observations, I
realise some of the might be a little opinionated. If anything it's
going to force a discussion on the topic, which is nice.
The series was developed on top of linux-next, and was tested on a
RPIv3B+ with audio, video and running vchiq_test.
Regards,
Nicolas
