I read that, but I had the impression you have a bunch of hardware so it
wasn't clear to me what you are actually testing. As the w1 driver

Instead of tuning the global cache options, you should just read the
chip's node in the /uncached/ directory. That way, the chip is read *in
any case* (and the cache is updated).
