Dear freebsd-{current,hardware}@,
Let me a give a few guiding comments for potential testers and
integrators of this patch.
First of all, let's start with a common pitfall:
* You have to update your /boot/device.hints, and then reboot. In no
other circumstance will the isa-based lm(4) or it(4) be probed. Manually
updating the hints with kenv(1) after the system has already been booted
has no effect on the isa modules. *
Second, since this patch is not only about the framework, but about some
Super I/O Hardware Monitoring drivers too, let me once again reiterate
on the popularity of the chips that are supported by the lm(4) and it(4)
drivers.
I have four boxes here, all run FreeBSD and OpenBSD. Let's see what
Super I/O chips they have:
* AOpen AX4G-N (845G + Intel Pentium 4 Northwood): Winbond W83627HF-AM
* ASUS Terminator C3 (VIA CLE266 + VIA C3 Samuel 2): Winbond W83627THF-A
* ASUS V3-P5G965 (G965 + Intel Core 2 Duo Allendale): Winbond W83627DHG-A
* PCCHIPS V21G (VIA CN700 + VIA C7 Esther): ITE IT8716F-S
Out of the above, Winbond W83627* are supported by lm(4), and ITE
IT8716F-S by it(4). (Obviously, the drivers support other chips, too. ;)
In general, most boards from Taiwanese manufacturers have either a
Winbond or ITE Tech Super I/O chips, supported by lm(4) and it(4)
respectively; e.g. if you have a Gigabyte or ASUS mainboard, then the
probability of you having one of these chips is quite substantial --
consider testing the patch if you are interested.
Supermicro boards also feature Winbond chips quite often -- feel free to
test.
Intel-branded boards, on the other hand, often use an SMBus-interfaced
Hardware Monitoring solution. I have none of those boards, so none of
the SMBus drivers were ported to FreeBSD yet.
Anyhow, I hope this information helps some potential testers and
integrators. ;)
Cheers,
Constantine.

Dear freebsd-{arch,current,hackers}@,
On this 256th day of 2007, it is my great pleasure to announce the
completion of my GSoC2007 project on porting the sysctl hardware sensors
framework from OpenBSD to FreeBSD.
All of the things that were planned to be ported from OpenBSD base
system to FreeBSD have now been ported.
The userland part of the framework is entirely source-code compatible
with OpenBSD. For example, you can take OpenBSD's stock sensorsd(8),
and it'll compile and work on FreeBSD with no modifications.
The framework is quite self-contained, so I think it is a safe bet to at
least try to get it into the tree even at this point, when the code
freeze is taking place in preparation for RELENG_7 branching.
Therefore, I hereby request that this patch be considered for immediate
inclusion into FreeBSD's main CVS repository.
The complete CVS patch is available from:
http://mojo.ru/us/GSoC2007.cnst-sensors.2007-09-13.patch.gz
For backup purposes, a copy of this CVS patch is also available in my
perforce branch, although it has tainted $P4$ tags in individual files,
so use perforce as a last resort:
http://p4web.freebsd.org//depot/projects/soc2007/cnst-sensors/cnst-sensors.2007-09-13.patch
Exact details on how to apply and test the patch are available in my
LiveJournal, along with certain other comments:
http://cnst.livejournal.com/38421.html#directions
If you have an Intel Core 2 processor, or a Winbond or ITE Tech Super
I/O chip on your board, then please test and report back on how your
tests went.
Best regards,
Constantine Aleksandrovich Murenin,
Google Summer of Code 2007 Student @ The FreeBSD Project. ;)

Change 126384 by [EMAIL PROTECTED] on 2007/09/13 23:01:55
On this 256th day of 2007, it is my great pleasure to
present a feature-complete port of the hardware sensors
framework from OpenBSD to FreeBSD.
Below is a complete `cvs diff` of cnst-sensors GSoC2007
project as of 2007-256.
It includes the following components, listed below in
the very same order as they are appearing in this diff:
* sample configuration file for sensorsd
* rc(8) script and glue code for sensorsd(8)
* sysctl(3) doc fixes for CTL_HW tree
* sysctl(3) documentation for hardware sensors
* sysctl(8) documentation for hardware sensors
* assorted KNF and bug-fixes for sysctl(8)
* support for the sensor structure for sysctl(8)
* coretemp(4) documentation
* it(4) documentation
* lm(4) documentation
* rc.conf(5) documentation for starting sensorsd(8)
* sensor_attach(9) et al documentation
* coretemp(4) conversion to the hw.sensors framework
* it(4) isa driver ported from OpenBSD
* lm(4) isa driver ported from OpenBSD
* /sys/kern/kern_sensors.c
o sensor_attach(9) API for drivers to register ksensors
o sensor_task_register(9) API for the update task
o sysctl(3) glue code
o hw.sensors shadow tree for sysctl(8) internal magic
* assorted KNF and bug-fixes for /sys/kern/kern_sysctl.c
* it(4) module for testing sensor_attach/detach et al
* lm(4) module for testing sensor_attach/detach et al
* <sys/sensors.h>
* assorted bug-fixes and HW_SENSORS definition for <sys/sysctl.h>
* sensors display for systat(1), including all documentation
* sensorsd(8) and all applicable documentation
The userland part of the framework is entirely source-code
compatible with OpenBSD 4.1, 4.2 and -current as of today.
All sensor readings can be viewed with `sysctl hw.sensors`,
monitored in semi-realtime with `systat -sensors` and also
logged with `sensorsd`. Third-party tools, for example a
plug-in for nagios, are also available. A separate patch
for ports/sysutils/symon will be provided upon request.
