Change the way that we sleep/wait for activity, to use select
rather than a fixed-length sleep, supplied by Julien Blache of
Debian:
Hi,
The attached patch for wmacpi makes it use select() instead of
sleeping. It also adjusts the timeout of the select() call
depending on the blink & scroll options.
If scrolling is not activated, there's no reason to wake up
10x/sec. If blinking is activated, waking up once per second is
enough. If blinking is not activated, then we can wake up just to
update the data and we're fine.
With scrolling and blinking disabled, this saves a number of
wakeups and helps battery life. Unfortunately there's another
source of wakeups that's probably due to libdockapp that still
makes 6 wakeups/seconds (in another thread it seems).
With this patch wmacpi makes a best effort to match the sample
rate set by the user, but that's hardly an issue I think.
I haven't released this patch yet in Debian, so if you like it and
want to roll out a release, feel free :) Otherwise I'll add it to
the package soon.
Thanks,
JB.
