It seems to create more issues than it fixes. Try to defend against
lost/late GPEs by using a callout to kick the state machine regulary.
Add some notes about the purpose and working of the driver.
separate powering up devices from restoring their state. This is required
on some machines where AcpiLeaveSleepState can fail due to an attempt to
access a powered off device.

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.
make sure to update the PCI Interrupt Register of all PCI devices using
it. This fixes interrupt with ACPI and w/o IOAPIC, when the BIOS didn't
route all interrupts correctly.
Reported by sborill@ and by Mathias De Belder in PR 37001, fix tested
by sborill@.
introduce ENVSYS_BATTERY_CHARGE, which is the same than an Indicator and
it's used to know if the battery is currently charging or discharging.
- Require two sensors at least for SME_CLASS_BATTERY to make the low-power
condition work: a ENVSYS_BATTERY_CAPACITY plus ENVSYS_BATTERY_CHARGE.
- Simplify sme_event_check_lowpower() and make it check the required
sensors in the SME_CLASS_ACADAPTER and SME_CLASS_BATTERY classes.
If the acadapter is not ready, trust the state returned by the battery
device.
Based on suggestion from joerg@.

- 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.
- Replace most inline assembly with proper functions. As a side effect
this reduces the size of amd64 GENERIC by about 120kB, and i386 by a
smaller amount. Nearly all of the inlines did something slow, or something
that does not need to be fast.
- Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL.
In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.
- Share a few more files between the ports.
- Other minor changes.

It will show WARNING, CRITICAL, LOW or NORMAL depending on the
state it is.
I like it better because I get to see the name of the device as it appears
in the DSDT, which sometimes makes sense and that way it's easier to locate
the relevant code when debugging.
E.g.:
PIC (PNP0000) [AT Interrupt Controller] at acpipcib0 not configured
DMAD (PNP0200) [AT DMA Controller] at acpipcib0 not configured
attimer0 at acpipcib0 (TMR, PNP0100): AT Timer
RTC0 (PNP0B00) [AT Real-Time Clock] at acpipcib0 not configured
pckbc0 at acpipcib0 (PS2K, PNP0303): kbd port
acpibat0 at acpi0 (BAT0, PNP0C0A-0): ACPI Battery (Control Method)
- mark (DIS)CHARGERATE as invalid when (DIS)CHARGING so that envstat
doesn't print some weird stats where the system appears to be doing
both
- handle the case when it's doing neither by marking *RATE as invalid
and setting CHARGING to OFF (because we're not charging, even though
we're not discharging)
- fix print_stats to print correct values in those cases, and a real
percentage (i.e., computed against LFCCAPACITY)
(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.
Tested by:
blymn: smsc(4).
bouyer: ipmi(4), mfi(4).
kefren: ug(4).
njoly: viaenv(4), adt7463.c.
riz: owtemp(4).
xtraeme: acpiacad(4), acpibat(4), acpitz(4), aiboost(4), it(4), lm(4).
* dev/ic/ug.c (main code shared by the attachments)
* dev/isa/ug_isa.c (isa attachment)
* dev/acpi/ug_acpi.c (acpi attachment)
That means that ug(4) can now be attached via ACPI.
Thanks to Mihai Chelaru for the good work.
This driver will report values from the Super I/O chip via ACPI.
It should be possible to overclock the system with this driver, but
it's not implemented yet.
All newer ASUS motherboards probably will work with this driver
(device ATK0110).

still enabled, as it could have been disabled through USERCONF.
Use it in amd64 and i386 mainbus code and skip all ACPI processing in case
it is disabled.
- make sleep state corresponding to standby/suspend changeable by using sysctl,
- make sure to generate APM events appropriately.
- arrange the code for getting power status.
acpiapm(4) always matches the first node of AML, which is unrelated
with acpiapm. Separate acpi(4)'s children into two individual interface
attributes.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.
Approved by core@. Fixes PR port-evbmips/32362.
backend for timecounters.
Due to known bugs in some chipsets, always read until we get 3 successive
samples which are monotonic, as FreeBSD does in its "safe" variant.
This can be refined later, either by chipset quirks or by a test (as
FreeBSD does).
Otherwise, if there are two resources definitions of the same type in _CRS,
the same one from _PRS will be used twice, which of course leads to errors.
Note: _PRS is Possible Resources Set
_CRS is Current Resources Set
XXX acpi_allocate_resources is still very weak, e.g. it completely ignores
StartDependentFn entries which are kind of a switch. But at least it's
slightly better that way.

stable, so do not depend on it!
To trigger sleep:
# sysctl -w machdep.sleep_state=<n>
Where <n> is typically 1 (standby), 3 (suspend), or 4 (hibernate).
