Call for Testing: upd(4)

Contributed by tbert on from the no-breaks-for-the-wicked dept.

Andre de Oliveira (andre@) has committed the upd(4) driver, which detects uninterruptible power supplies (UPS) attached to USB, which will show up in the dmesg: 

uhidev0 at uhub1 port 1 configuration 1 interface 0 "American Power Conversion Back-UPS RS 500 FW:30.j5.I USB FW:j5" rev 1.10/0.06 addr 2
uhidev0: iclass 3/0, 98 report ids
upd0 at uhidev0

The UPS will then have a few sensors attached, which will show you running on battery: 

% sysctl hw.sensors.upd0
hw.sensors.upd0.indicator0=Off (Charging)
hw.sensors.upd0.indicator1=On (Discharging)
hw.sensors.upd0.indicator2=Off (ACPresent)
hw.sensors.upd0.indicator3=On (BatteryPresent)
hw.sensors.upd0.indicator4=Off (ShutdownImminent)
hw.sensors.upd0.percent0=100.00% (FullChargeCapacity)
hw.sensors.upd0.percent1=94.00% (RemainingCapacity)

And charging: 

% sysctl hw.sensors.upd0
hw.sensors.upd0.indicator0=On (Charging)
hw.sensors.upd0.indicator1=Off (Discharging)
hw.sensors.upd0.indicator2=On (ACPresent)
hw.sensors.upd0.indicator3=On (BatteryPresent)
hw.sensors.upd0.indicator4=Off (ShutdownImminent)
hw.sensors.upd0.percent0=100.00% (FullChargeCapacity)
hw.sensors.upd0.percent1=91.00% (RemainingCapacity)

Please note that this still requires an additional patch: 

upd(4) is now enabled to be built for amd64, macppc and sparc64, thanks
to mpi@ uhidev diff.

still, to get it attaching correctly, these vendor/product id pairs need
to be removed from usb_quirks.c.

read it as: these devices won't attach to ugen anymore.

Please note that this is a new driver under active development, so your UPS may not be supported. The only way that OpenBSD will get out-of-the-box support for these devices is for as wide a variety as can be tested to get tested, so patch, build, attach, and report any and all failures to the author.

UPDATE: andre@ has made it known that this no longer requires a patch; snapshots that are built after the time of publication should have the change.

    It can be monitored in sensorsd like so:

    hw.sensors.upd0.indicator0:low=1:high=2:command=echo "who turned %2 the lights?" | mail -s "power sensors" root
    And from snmp:

    $ snmpctl snmp walk localhost oid 1.3.6.1.4.1.30155.2.1.2.1 | fgrep .5=
sensorEntry.sensorIndex.5=5
sensorEntry.sensorDescr.5="ACPresent"
sensorEntry.sensorType.5=9
sensorEntry.sensorDevice.5="upd0"
sensorEntry.sensorValue.5="on"
sensorEntry.sensorUnits.5=""
sensorEntry.sensorStatus.5=0

    Where is the list of hardware this is for? Is this meant for normal APC UPS devices that have a normal USB connection? (probably a dumb question, but I didn't see a list of supported hardware in the manpage)

      Look for "VENDOR".

      It is an USB hid-standard based implementation.
      Don't be afraid, download a recent snapshot, plug your UPS usb cable and enjoy the fun.

        The majority of USB UPS use one of two basic types of interface - one is basically rs232-over-usb, and the other is a "HID power device", this driver is for the latter.

        If you have a non-working device, it would be useful to post pkg_add usbutils and post the relevant output from "lsusb -v" for the device, along with the usual dmesg/description of what happens.
