Xeon support
|
||||
------------
|
||||
|
||||
Some Xeon processors have real max1617, adm1021, or compatible chips
|
||||
within them, with two temperature sensors.
|
||||
Netburst-based Xeon support
|
||||
---------------------------
|
||||
|
||||
Other Xeons have chips with only one sensor.
|
||||
Some Xeon processors based on the Netburst (early Pentium 4, from 2001 to
|
||||
2003) microarchitecture had real MAX1617, ADM1021, or compatible chips
|
||||
within them, with two temperature sensors. Other Xeon processors of this
|
||||
era (with 400 MHz FSB) had chips with only one temperature sensor.
|
||||
|
||||
If you have a Xeon, and the adm1021 module loads, and both temperatures
|
||||
appear valid, then things are good.
|
||||
If you have such an old Xeon, and you get two valid temperatures when
|
||||
loading the adm1021 module, then things are good.
|
||||
|
||||
If the adm1021 module doesn't load, you should try this:
|
||||
modprobe adm1021 force_adm1021=BUS,ADDRESS
|
||||
ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
|
||||
If nothing happens when loading the adm1021 module, and you are certain
|
||||
that your specific Xeon processor model includes compatible sensors, you
|
||||
will have to explicitly instantiate the sensor chips from user-space. See
|
||||
method 4 in Documentation/i2c/instantiating-devices. Possible slave
|
||||
addresses are 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e. It is likely that
|
||||
only temp2 will be correct and temp1 will have to be ignored.
|
||||
|
||||
If you have dual Xeons you may have appear to have two separate
|
||||
adm1021-compatible chips, or two single-temperature sensors, at distinct
|
||||
addresses.
|
||||
Previous generations of the Xeon processor (based on Pentium II/III)
|
||||
didn't have these sensors. Next generations of Xeon processors (533 MHz
|
||||
FSB and faster) lost them, until the Core-based generation which
|
||||
introduced integrated digital thermal sensors. These are supported by
|
||||
the coretemp driver.

|
||||
details.

|
||||
|
||||

How to Get Your Patch Accepted Into the Hwmon Subsystem
|
||||
-------------------------------------------------------
|
||||
|
||||
This text is is a collection of suggestions for people writing patches or
|
||||
drivers for the hwmon subsystem. Following these suggestions will greatly
|
||||
increase the chances of your change being accepted.
|
||||
|
||||
|
||||
1. General
|
||||
----------
|
||||
|
||||
* It should be unnecessary to mention, but please read and follow
|
||||
Documentation/SubmitChecklist
|
||||
Documentation/SubmittingDrivers
|
||||
Documentation/SubmittingPatches
|
||||
Documentation/CodingStyle
|
||||
|
||||
* If your patch generates checkpatch warnings, please refrain from explanations
|
||||
such as "I don't like that coding style". Keep in mind that each unnecessary
|
||||
warning helps hiding a real problem. If you don't like the kernel coding
|
||||
style, don't write kernel drivers.
|
||||
|
||||
* Please test your patch thoroughly. We are not your test group.
|
||||
Sometimes a patch can not or not completely be tested because of missing
|
||||
hardware. In such cases, you should test-build the code on at least one
|
||||
architecture. If run-time testing was not achieved, it should be written
|
||||
explicitly below the patch header.
|
||||
|
||||
* If your patch (or the driver) is affected by configuration options such as
|
||||
CONFIG_SMP or CONFIG_HOTPLUG, make sure it compiles for all configuration
|
||||
variants.
|
||||
|
||||
|
||||
2. Adding functionality to existing drivers
|
||||
-------------------------------------------
|
||||
|
||||
* Make sure the documentation in Documentation/hwmon/<driver_name> is up to
|
||||
date.
|
||||
|
||||
* Make sure the information in Kconfig is up to date.
|
||||
|
||||
* If the added functionality requires some cleanup or structural changes, split
|
||||
your patch into a cleanup part and the actual addition. This makes it easier
|
||||
to review your changes, and to bisect any resulting problems.
|
||||
|
||||
* Never mix bug fixes, cleanup, and functional enhancements in a single patch.
|
||||
|
||||
|
||||
3. New drivers
|
||||
--------------
|
||||
|
||||
* Running your patch or driver file(s) through checkpatch does not mean its
|
||||
formatting is clean. If unsure about formatting in your new driver, run it
|
||||
through Lindent. Lindent is not perfect, and you may have to do some minor
|
||||
cleanup, but it is a good start.
|
||||
|
||||
* Consider adding yourself to MAINTAINERS.
|
||||
|
||||
* Document the driver in Documentation/hwmon/<driver_name>.
|
||||
|
||||
* Add the driver to Kconfig and Makefile in alphabetical order.
|
||||
|
||||
* Make sure that all dependencies are listed in Kconfig. For new drivers, it
|
||||
is most likely prudent to add a dependency on EXPERIMENTAL.
|
||||
|
||||
* Avoid forward declarations if you can. Rearrange the code if necessary.
|
||||
|
||||
* Avoid calculations in macros and macro-generated functions. While such macros
|
||||
may save a line or so in the source, it obfuscates the code and makes code
|
||||
review more difficult. It may also result in code which is more complicated
|
||||
than necessary. Use inline functions or just regular functions instead.
|
||||
|
||||
* If the driver has a detect function, make sure it is silent. Debug messages
|
||||
and messages printed after a successful detection are acceptable, but it
|
||||
must not print messages such as "Chip XXX not found/supported".
|
||||
|
||||
Keep in mind that the detect function will run for all drivers supporting an
|
||||
address if a chip is detected on that address. Unnecessary messages will just
|
||||
pollute the kernel log and not provide any value.
|
||||
|
||||
* Provide a detect function if and only if a chip can be detected reliably.
|
||||
|
||||
* Avoid writing to chip registers in the detect function. If you have to write,
|
||||
only do it after you have already gathered enough data to be certain that the
|
||||
detection is going to be successful.
|
||||
|
||||
Keep in mind that the chip might not be what your driver believes it is, and
|
||||
writing to it might cause a bad misconfiguration.
|
||||
|
||||
* Make sure there are no race conditions in the probe function. Specifically,
|
||||
completely initialize your chip first, then create sysfs entries and register
|
||||
with the hwmon subsystem.
|
||||
|
||||
* Do not provide support for deprecated sysfs attributes.
|
||||
|
||||
* Do not create non-standard attributes unless really needed. If you have to use
|
||||
non-standard attributes, or you believe you do, discuss it on the mailing list
|
||||
first. Either case, provide a detailed explanation why you need the
|
||||
non-standard attribute(s).
|
||||
Standard attributes are specified in Documentation/hwmon/sysfs-interface.
|
||||
|
||||
* When deciding which sysfs attributes to support, look at the chip's
|
||||
capabilities. While we do not expect your driver to support everything the
|
||||
chip may offer, it should at least support all limits and alarms.
|
||||
|
||||
* Last but not least, please check if a driver for your chip already exists
|
||||
before starting to write a new driver. Especially for temperature sensors,
|
||||
new chips are often variants of previously released chips. In some cases,
|
||||
a presumably new chip may simply have been relabeled.

2. A single work item that consumes lots of cpu cycles
|
||||
|
||||
The first one can be tracked using tracing:
|
||||
|
||||
$ echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event
|
||||
$ cat /sys/kernel/debug/tracing/trace_pipe > out.txt
|
||||
(wait a few secs)
|
||||
^C
|
||||
|
||||
If something is busy looping on work queueing, it would be dominating
|
||||
the output and the offender can be determined with the work item
|
||||
function.
|
||||
|
||||
For the second type of problems it should be possible to just check
|
||||
the stack trace of the offending worker thread.
|
||||
|
||||
$ cat /proc/THE_OFFENDING_KWORKER/stack
|
||||
|
||||
The work item's function should be trivially visible in the stack
|
||||
trace.
