FS#2462 - More AJR v1 recharging cleanup

Continuing to build on the last recharging patch [
1116884 ] “More aggressive Recorder V1 charging.”

This patch does more consoladation and rearranging to
meet my asthetic expectations. I’m running out of deck
chairs to rearrange, however.

Also fixed is a bug introduced in the [ 1116884] patch
where I inadvertantly bypassed the “top-off” stage in
the recharge cycle, going from full charge to trickle.
Ooops, too much code reorganization.

I removed the battery percentage limitations of -1% per
minute (-3% per minute for USB). I don’t know if this
is an acceptable removal or not – I don’t notice that
the battery percentage bounces around significantly,
but I don’t watch it that closely either. My
presumption is that the better battery voltage
filtering of the [ 116884 ] patch makes the additional
rate limiting unnecessary.

I did some minor improvements to the debug log file
flushing: if the disk is active and there is stuff to
flush, I call fsync(). Otherwise, I only call fsync()
every 10 minutes. This is intended to minimize
extraneous disk accesses. I also fixed an error on
shutdown (fd > 0) vs (fd >= 0) which could have been
the cause of some of the empty log files.

The patch again didn't apply cleanly, but manually was OK.

The patch doesn’t apply cleanly to current cvs, but I’ll se what
I can do.

Hmm, I patched it manually, but am far from sure the result is
correct. E.g. I get compilation errors for the Ondio target.
Jerry, can you please check, and/or file your plain
powermgmt.c here? (It’s safe to assume nobody else is
modifying it now.)

Hi Jörg and other patchwatchers:

The New Improved[tm] 050320.patch (attached) applies and
compiles cleanly on the Player, AJR, AJRv2 and Ondio.

In addition to the previously mentioned bug fixes and
improvements, this adds a proportional term to the recharge
control loop (giving us PI of the traditional PID control
method). (Trivia: Adding a derivative term is not necessary.)

I rearranged the debug battery screens somewhat and changed
the information on them to display things like the P and I
terms.

Acting on Jens’ tip that the Ondio “?” may be related to the
multiple battery type handling, I changed the set to -1 to a
call to battery_level_update() – since I don’t have an
Ondio, I cannot test this.

Please take this for a spin and send me feedback if you run
into problems (preferrably on the email list). This should
be “production ready”: I don’t plan to add any more features
or clean up to this patch unless there are problems.

Thanks,
gvb
