As many know, getting standardized dvb signal info in linux has been a
want for a very long time for a lot of users (and developers). There
has been several talks/threads about it but nothing was ever merged.
The subject has come up once again and Mauro has posted a patch for
review. I know that there are at least a handful of coders here who
have interest in this, including Klaus. I strongly urge anyone who
would like to see this finally happen to take a few minutes and read
the links below. Further, it would be great if people actively
participated in the discussion so please post anything you may like to
contribute to the discussion!
I have read the discussion. The kernel to userspace interface is not allowed
to change, as this would brake userspace programs, so any fix would have
to come from a new kernel side interface. Therefore at the VDR side we have
two options:
1)Wait for the new kernel interface to happen with a standard way to report
quality and strength.
That's what this is about!
2)Implement work arounds for each receiver. In my opinion this has to be
done anyway, in order to let VDR run on old kernel versions.
You have to consider the benefit of this. Just because you technically
_could_ make it work on ancient kernels, doesn't mean it's worth the
time effort to do so. IMO, maintaining a bunch of workarounds is a
total waste of time because there aren't enough users running ancient
kernels to justify the work it takes to do this. I'm not scared of
progress either. If using a newer version of VDR means using a newer
kernel, so be it -- that's nothing to be scared of.
Devs, users, or both are likely to experience growing pains for things
to advance. The bar can't be so low that it doesn't exist. Minimum
requirements aren't evil, sometimes they're necessary. Also, users
have the option of using media_build for their drivers. Then they can
use however old of a kernel media_build is backported to. That's more
than reasonable if you ask me.
