critical-min and critical-max; also, a battery warning-capacity is
added in addition to a critical-capacity.
2. usr.sbin/envstat is modified to introduce a -W command line switch to
display the warning-* values instead of the critical-* values, and
envstat(8) and envsys.conf(5) man pages are updated appropriately.
3. Treat user-defined limits as a single continuum and generate a single
event regardless of how many boundaries a change in sensor value
crosses; ditto for driver-defined limits.

- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>
(and its dictionary created) successfully and use it in the
POWER_EVENT_RECVDICT ioctl to check if the dictionary is ready before
calling prop_dictionary_copyout_ioctl().
This fixes a rare condition when too many events are enqueued and
there wasn't time to create the dictionary, so prop_dictionary_copyout_ioctl()
fails with a NULL pointer dereference.

- Introduce sme_class into the sysmon_envsys struct to specify a
class; currently there are two classes: SME_CLASS_ACADAPTER and
SME_CLASS_BATTERY.
- Add a new envsys event: PENVSYS_EVENT_LOW_POWER that is reached when
all SME_CLASS_BATTERY devices are in CRITICAL/LOW state and there's not
any SME_CLASS_ACADAPTER connected.
- Add the 'low-power' event into the sensor_battery script that will
shutdown the system gracefully via 'shutdown -p'. If powerd(8) is
not running, cpu_reboot(9) with RB_POWERDOWN is used.
- Make acpiacad(4) a SME_CLASS_ACADAPTER device and acpibat(4) a
SME_CLASS_BATTERY device.
Update the documentation accordingly to these changes.
at the same time and the code accessed to an unexistent dictionary:
- Rather than using a global dictionary, use a singly linked list to
access to the dictionaries, one per event.
- When the dictionary has been sent to userland, destroy it and remove
it from the list.
With that change it is possible to receive multiple events at the
same time without panics; again thanks to rmind@ for comments and help
with locking.
Reviewed and ok by rmind.
of another object that will be released shortly.
- Fix a memleak: add sysmon_power_destroy_dictionary() and remove
all objects that are currently in the dictionary and finally release
the dictionary.
(at least three or four persons were against it).
- Add a new sensor type: ENVSYS_BATTERY_STATE, this uses value_cur
and some predefined values in a static table, like ENVSYS_DRIVE.
- Move all static tables to sysmon_envsys_tables.c and use a function
on it to retrieve a pointer to the struct of the specified type.
- Rename the ENVSYS_FMONDRVSTCHANGED to ENVSYS_FMONSTCHANGED and make
it generic for Battery state and drive sensors (this flag enables
monitoring on these sensors when state has been changed).
- Update sysmon_penvsys_event() to report state changes on
ENVSYS_BATTERY_STATE sensors and remove other type of events, with
PENVSYS_EVENT_STATE_CHANGED they are not necessary anymore.
(Part 1: API)
* 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.

be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
Right now, only power switch state change events are supported. This
is a work-in-progress.
* Add support to sysmon for delivering power mangement events to userland.
Add poll, kqueue, and read entry points to sysmon.
* Adapt ACPI to use the new generic <sys/power.h> event types.
This provides the kernel support for a forthcoming powerd(8) which can
do nice things like gracefully shut the system down when an ACPI power
button is pressed.
provide some VERY basic support for power/sleep buttons and lid switches;
if someone presses the power button, shut down the system semi-gracefully.
Eventually, we will send events for all types of button/lid events down
to a userland power management daemon, which will be able to define a
separate policy for each button/switch.
