+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

+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.

+ 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.

* Unless work items are expected to consume a huge amount of CPU
cycles, using a bound wq is usually beneficial due to the increased
level of locality in wq operations and work item execution.
+
+
+7. Debugging
+
+Because the work functions are executed by generic worker threads
+there are a few tricks needed to shed some light on misbehaving
+workqueue users.
+
+Worker threads show up in the process list as:
+
+root 5671 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/0:1]
+root 5672 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/1:2]
+root 5673 0.0 0.0 0 0 ? S 12:12 0:00 [kworker/0:0]
+root 5674 0.0 0.0 0 0 ? S 12:13 0:00 [kworker/1:0]
+
+If kworkers are going crazy (using too much cpu), there are two types
+of possible problems:
+
+ 1. Something beeing scheduled in rapid succession
+ 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.
