Could you attach (or, better, upload to pastebin.com) the whole log
file. Are you running vdr with --log=3? I need to see 'idle timer' debug
messages and some other debug stuff. Could you also apply this change

--

Thanks for testing.

Best,
Sergey Chernyavskiy.

Richard F - May 31, 2016, 7:43 p.m.
OK Sergey, I've posted a log with your patch applied + log level 3 -
about 3 hours worth
There was a recording 16:15 to 16:45, other than that idle
I can run it for longer if you need it, though it's creating a fair bit
of log.
I seem to get a lot of erroneous EPGsearch results at level 3, not sure why.

Let me know what it tells you
Thanks
Richard

glenvt18 - June 1, 2016, 2:49 a.m.
From what I can see, everything works as expected. You can safely lessen
the power-down timeout to 3 minutes. This will be enough for EPG scan as
you have at most 8 transponders/multiplexes which gives 8 * 1/3 = 2m40s
- see 'EIT scan ...' messages.

As for those small intervals of activity you mentioned, it happens
because some 'preparation' work is done before a timer starts.  VDR
tries to switch to the timer's transponder and gather EPG data. For a
VPS timer this begins within VPS margin and an hour before the timer
start time.  For a non-VPS timer it begins one minute before the timer
start time.  I've added 30 seconds to the occupied timeout (see my
cDevice::SetOccupied() comment) to avoid frequent on/off switching. So,
you're likely to see 38-second (or, sometimes, a bit more) periods of
activity. If you still worry about it, keep you server idle for 2 hours
before a nearest VPS timer starts and paste the log.

I've removed 'sudo' from the monitor script:
http://pastebin.com/8JDffAXF

Run it as user 'vdr' for some time. It will draw you a nice 'map' of
your devices' activity.

If you notice channel switch failures, let me know.

Do your tuners get warm when active?

Thanks again for testing.

Best,
Sergey Chernyavskiy.

OK, I'll keep an eye on it. No adverse effects yet - good work, thanks.

I'm doing some other testing and stuff atm so want to keep the server up -
I'll possibly take it down at the weekend, make some power measurements
and post them

Yes, the TV tuners always did run warm, and I recall that when VDR is
stopped the power is several watts lower (not because of VDR/CPU load
itself according to stats, it's when the tuners go active - hence my
interest in your patch).

As the server also runs the home automation/lights/heating/security,
CCTV, mail server, and file storage/Owncloud it's not an option to shut
it down when not recording, and I have t choose when to take it down !

That's the main purpose of this feature. You don't have to switch off
your tuners physically, close your connections or put your server into
sleep (and ARM devices usually don't have a sleep mode at all). You can
stream your recordings, watch movies and do other stuff with your server
and, at the same time, keep your tuners cold.

> OK, I'll keep an eye on it. No adverse effects yet - good work, thanks.

I've modified the monitor script:
http://pastebin.com/DR4gUdZR

Now it prints timestamps and it's output can be searched and grep-ed.
Run it with '|tee' for several days.

Best,
Sergey Chernyavskiy.

Richard F - June 6, 2016, 10:21 a.m.
Sergey,

I took down the server at the weekend to install a newly built kernel
and insert the power monitor.

47W  - All services running at idle, tuner power saving disabled
44W - All services running at idle, tuner power saving enabled

As tuners are powered down most of the time, that's a handy 6% average
saving.

The hardware is an HP 8300CMT with high efficiency PSU, G2130 Ivy bridge
CPU and a 3 x 2T RAID + KMC4400R for CCTV video capture,  the tuners are
PCTV Nanostick 290e for HD/SD (USB2) and an old Leadtek DTV1000 T (PCI)
for SD - both of which are super-reliable BTW.

Obviously other tuners will vary, and if the PSU isn't the efficient 90%
one like this, the savings will be marginally more.

Richard

Hi Richard,

Unlike DVB-S/S2 tuners your DVB-T/T2 ones don't have to supply power to
a LNB (which draws at least 2W). So, your 3W drop can be considered as
"normal". For your USB stick even 1W saving can be helpful.

Thanks again for testing.

Sergey.

Richard F - June 8, 2016, 4:23 p.m.
I'm happy with just a modest power saving.

Put in context, on my system, 3Wh ~ 25 mins SD content transcoding to
H264/AAC = 30-40% disk space reduction with no noticeable loss of
quality.  So ~70Wh saving / day pays for ongoing SD recording
compression and multi-TB historical library compression in about 3
months. I free up a 1TB or so of RAID :-)

Thanks
Richard

Tobias Grimm - June 12, 2016, 9:23 a.m.
Hi,

I've tried this as well now.

I have two Cine S2 dual-tuner cards (an older 5.5 running on ngene driver
and a 6.5 running with the ddbridge driver) attached to a cascadable
multiswitch.

The VDR (2.2) runs as a headless server with the vnsi plugin to allow to
connect Kodi clients to the VDR.

With all adapters active, I see a power consumption of about 50W. When
your power-saving patch kicks in, this is reduced by about 7W to 43W.

So far this seems to work fine. Thanks for this patch!

+1 for including this into vanilla VDR.

bye,

Tobias
Richard F - June 25, 2016, 9:25 a.m.
Hi Sergey,

My VDR setup started having a bit of a fit last night, and has been doing this for the last 8 hours (no changes my end)
Before I restart VDR, any tests I can do to diagnose?

It seems to have started after a live stream (Kodi/VNSI) + a recording stopped 
- here's the VDR-related log from where the connection started to where the problem seemed to start
It may be that the VNSI plugin is keeping the receiver active ?
(the VNSI-Error: cxSocket::read   error occurs 2 or 3 times a day - not unusual, nor is any other log entry)

Hi Richard,

As there are no debug messages in your log I tried to reconstruct some
of them (power-related) - see my comments. Note that an extra second is
added to all timeouts due to the 'greater than' comparison. It was done
on purpose to add some save margin. Power-saving looks to work OK. But.
I don't see any 'timer ... start/stop' or 'record ...' messages in your
log. So, I have some questions:
1) Did you fail to record 'The Big C & Me' at 01:05 and 'Greenberg' at
01:35?
2) Did you cancel 'Greenberg'?
3) Was your streaming interrupted?
4) What is your vnsi streaming priority?
5) What is your recording priority?
6) Are the channels you recorded and the channels you streamed on the same
transponder? I'm asking this because I see device 1 being idle all that
time.
7) What happens with your VDR when a vnsi streaming is interrupted by a
higher priority recording on the same device but on another transponder?
8) What timers (their dates) did you have from Jun 24 00:00 to Jun 24
04:00? 
9) What is your Vps Margin setting?

No, that was just a (standard) notification from VDR that the running
status of a program had changed

No, VDR was idle before I started up Kodi/VNSI at around 01:00.

Actually looking back through the log some more, it seems that Kodi had
one of it's regular hiccup startup problems here.
Basically it starts, then crashes, then starts, often 2 or 3 times. This
is a known issue - the Kodi devs say they've changed the startup
mechanism in newer versions, but these aren't stable enough for regular
use for various other reasons.

Not sure I have a VNSI priority, at least there isn't a setup variable
for it.

Generally 50 or 99. But in this case it wasn't recording, just streaming.

As above, there was only 1

Not tested.

600

On reflection I think this is really a VNSI problem, possibly a
side-effect of locking up the VNSI process.
I have had a similar situation in the past (before adding your patch)
where VNSI server plugin locks up after a client hiccup start, then any
client trying to connect keeps trying to attach and times out. This time
the client didn't time out (as I recall), but it was late, so I left it
and went to bed...!

I'll monitor for any other effects.

thanks

It's under Settings->Add-ons->My add-ons->PVR clients->

In this case your VDR might have been trying to update EPG for the
timers scheduled later, probably, next night. Anyway, it's all about
VDR's internal logic for updating timers' EPG events and has nothing to
do with power saving. Every time a VDR decides to update EPG for a
channel with a timer scheduled the device's frontend must be opened
prior to zapping and kept open for a while (38 sec as you see in the
log). If you have power-related issues you're likely to see ioctl()
errors in the log and emergency exits after a recording starts (VDR will
be restarted in this case).

Let me know.
