ipmi(4): Fixed a bug that incorrect condition is notified.

When the value obtained from the sensor is below the lower limit of
the critical threshold, it is notified that the value is below the lower
limit of the warning threshold.

Back to using aprint_error() and get more info about the error so we can

Be a little more clear and consistent about harvesting entropy from devices:

1) deprecate RND_FLAG_NO_ESTIMATE

2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE

3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
   RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME

5) Make entropy harvesting from environmental sensors a little more generic
   and remove it from individual sensor drivers.

6) Remove individual open-coded delta-estimators for values from a few
   places in the tree (uvm, environmental drivers).

7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
   that had stubbed out code, other minor cleanups.

Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files).  Tested with release

Keep condvar wmesg within 8-char limit.

For sensors with inverted value (1/x function), exchange lower and upper

sc_cmd_mtx protects a command sequence, no longer abuse it for delays.

Initialize mutexes and condition variables in attach and not in the
asynchronously started kernel thread.

Increase BMC spin timeout from 5ms to 15ms, this is necessary to detect
the BMC in a HP ML110G4 reliably.

Implement non-linear sensors as defined in IPMIv2.0 with some crude
32.32 fixed point arithmetic. This adds some small errors as logarithm
and power functions are only approximated.

Fix sensor index mapping so that sensor limits are computed correctly.

Register ipmi(4) with power management subsystem so we might have a chance
of suspending.  Suspending will still be denied if the watchdog is active.

As discussed on tech-kern@

Fixes a bug in previous, exposed by

# drvctl -d ipmi0

*lockdebug panic here*

Overhaul synchronization in ipmi(4): synchronize all access to
device registers with a mutex.  Convert tsleep/wakeup calls to
cv_wait/cv_signal.

Do not repeatedly malloc/free tiny buffers for sending/receiving
commands, but reserve a command buffer in the softc.

Tickle the watchdog in the sensors-refreshing thread.

I am fairly certain that after the device is attached, every register
access happens in the sensors-refreshing thread.  Moreover, no
software interrupt touches any register, now.  So I may get rid of
the mutex that protects register accesses, sc_cmd_mtx.

sync with head.

Store the limit values directly in the driver-private sensor data since
we don't have access to sysmon_envsys(8)'s copy at refresh time.  (The
refresh is driven completely within the driver, and sysmon is uninvolved.)

Resolves unexpected alarms (as reported by David Young) such as over-limit
alarms on fan sensors which have only lower limit values.

Don't extract upper/lower limit values if the values are not valid.

Correct comparison of cur_value against lower-limits.

Adapt to new features available in sysmon_envsys:

1) expose the built-in limits to user-land (via envstat(8)), and
2) allow user-specified limits to override the built-in limits.

No comments received from current-users@ over 2-week period.

Speed up ipmi attach a bit, although boot times on my workstation still suck:

Separate checking of sensor value vs threshold/limit value into two
routines, so we can distinguish between an over-limit vs under-limit
condition.  Set sensor state appropriately based on which threshold
is exceeded.

To do: come up with a means of detecting non-existent fans vs broken
fans.  Currently, both report a valid value of "0 RPM" at least on
some platforms.

Extend the envsys2 API (one more time, sorry) as defined in:

http://mail-index.netbsd.org/tech-kern/2007/11/09/0001.html

sysmon_envsys_create() and sysmon_envsys_destroy() were added to
create/destroy sysmon_envsys objects (and its TAILQ/LIST for sensors/events).

sysmon_envsys_sensor_attach() and sysmon_envsys_sensor_detach() were
added to attach/detach sensors to a specified sysmon_envsys device.

The events framework is now per device and configurable via the
ENVSYS_SETDICTIONARY ioctl or /etc/envsys.conf and envstat(8).

Update all users and documentation to reflect these changes.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

Start with all sensors in ENVSYS_SINVALID state, and switch to ENVSYS_SVALID
(or other, depending on result) once the sensor has been read.
This way envstat(8) won't show sensors which have not yet their correct value.

ipmi_sensor_status: if state is ok return ENVSYS_SVALID and not
ENVSYS_WARN_OK, the latter is deprecated on envsys2.

Use PRIx64 for a 64-bit quantity instead of llx in a debug print.

- On Intrusion sensors, if something is not ok return a critical event.
- On Power Supply sensors:
	* if power supply is not installed, return a critical event.
	* if power supply is installed but not powered on, return a
	  warnover event.

Adapt to callout API change.

Imported envsys 2, a brief description of the new features:
(Part 2: drivers)

* Support for detachable sensors.
* Cleaned up the API for simplicity and efficiency.
* Ability to send capacity/critical/warning events to powerd(8).
* Adapted all the code to the new locking order.
* Compatibility with the old envsys API: the ENVSYS_GTREINFO
  and ENVSYS_GTREDATA ioctl(2)s are supported.
* Added support for a 'dictionary based communication channel' between
  sysmon_power(9) and powerd(8), that means there is no 32 bytes event
  size restriction anymore.
* Binary compatibility with old envstat(8) and powerd(8) via COMPAT_40.
* All drivers with the n^2 gtredata bug were fixed, PR kern/36226.

- Add a flag argument to brelse() to be set into the buf's flags, instead

- Add a "struct cpu_info *" argument to kthread_create(), to be used to
  create bound threads. Change "bool mpsafe" to "int flags".
- Allow exit of LWPs in the IDL state when (l != curlwp).
- More locking fixes & conversion to the new API.

Nuke the deferred kthread creation stuff, as it's no longer needed.
