Expose a sysctl interface hw.acpi.thinkpad<M>.bat[<N>].<behavior> to control
some aspects of battery charging behavior on supported systems:

charge_start
threshold below which to start charging (in %, 0-99)

charge_stop
threshold above which to stop charging (in %, 1-100)

force_discharge
discharge while on AC power, e.g., for calibration

charge_inhibit
inhibit charging while on AC power

thinkpad cosmetic patches (Malte Dehling)

thinkpad(4): Don't detach on shutdown.

There's no important state that needs to be recorded, or resources
that need to be relinquished, so detach-on-shutdown isn't necessary.

At the moment, detach-on-shutdown is actually harmful here: if
shutdown is triggered by a sysmon power switch event, then
config_detach will be called from the sysmon taskqueue, but
thinkpad_detach has to wait for ACPI notifiers to finish running
which means waiting for the sysmon taskqueue -> deadlock or crash.

We should maybe arrange to do config_detach from a thread other than
the sysmon taskqueue thread to avoid this class of problems -- but
for now, thinkpad(4) has no reason to detach on shutdown anyway, so
let's take the easy path.

Note: There are many drivers that set DVF_DETACH_SHUTDOWN which
probably shouldn't; the flag means the kernel _will_ detach on
shutdown, not that it _may_. Even those that do need to record state
or relinquish resources might be better served by pmf shutdown hooks
which can skip freeing software resources for faster shutdown.

thinkpad(4): Omit workaround for acpiec_bus_read.

acpiec_bus_read now initializes the whole ACPI_INTEGER like its
signature suggests, so we don't need to pick out the low bits of the
result or carefully avoid undefined behaviour from uninitialized
stack garbage.

thinkpad(4): Fix evaluation of MHKA on version 2 devices.

Need to pass an argument.

Add some more Thinkpad hotkeys.

thinkpad(4): Add dtrace probe for hotkey events.

thinkpad(4): Attach at LEN0268 with v2 Thinkpad hotkeys too.

branches: 1.49.4; 1.49.6;
Use acpi_compatible_match().

branches: 1.48.2;
With the recent change of the EC address space handler, we no longer get
an ACPI_INTEGER in host byte order but a byte sized buffer with little
endian data.

Extract only the low 8 bits from buffer to get the fan speed again.

Fix undefined behavior in thinkpad_mask_init(). Found by kUBSan.

branches: 1.46.18; 1.46.24;
Split toggles for bluetooth and wwan and use specific ACPI objects
where present.
Also make driver detach on shutdown.

Update module dependencies for all the existing modules that depend on sysmon components.

branches: 1.44.12;
reverse the polarity of the extra key option, always enabling them.

Define THINKPAD_EXTENDED_HOTKEYS to enable more hotkeys on ThinkPads.
This has only been tested on a T61.
XXX: Should we put THINKPAD_EXTENDED_HOTKEYS into a opt_*.h include
(defflag) or just always enable it?

Match LEN0068 in thinkpad(4) too, as newer Thinkpads report.

Tested on a W530. Lots of stuff is missing, though.

branches: 1.41.2;
Collect rnd(9) entropy from coretemp(4), acpibat(4), aibs(4), hpacel(4),
thinkpad(4), and aps(4).

add function switch to switch on/off "wireless WAN", aka GSM et al modem
not tested to actually work, extensively tested not to do any harm if you
don't have a wwan

branches: 1.39.2; 1.39.8;
Initialize sensor state before trying to register.

Don't update the value_{min,max} - these fields are not {low,high}-water
marks, and setting them without also updating the ENVSYS_FVALID_{MIN,MAX}
flags is quite pointless.

branches: 1.37.2;
Simplify a little. No functional change.

Use the common power resource code. Also add a comment explaining
what can happen if we do not power on the resource upon resume from S3.

Use wireless function key to toggle not only bluetooth but also
telephony (GPRS/UMTS/..) like other operating systems.

Use ioconf for the module declarations.

branches: 1.33.2;
Use AcpiOsReadPort/AcpiOsWritePort instead of inb/outb so I can get rid of
of the i386 and x86_64 ifdefs.

branches: 1.32.2;
Use "temperature #" and "fan speed #" rather than "TMP#" and "FAN#" for the
sensor names. Remove white space. No functional change.

Bump WARNS to 4.

As discussed with jmcneill@, install a global "bus notification handler"
that receives all notifications and deliver notifications to drivers via it.

No need to spread the ACPICA type system any more than is necessary:

UINT8 -> uint8_t and UINT32 -> uint32_t.

branches: 1.28.2;
Remove <dev/acpi/acpica.h> from all files. It is included from
<dev/acpi/acpivar.h>. Ditto for <dev/sysmon/sysmonvar.h>, <sys/bus.h>,
<dev/pci/pcivar.h>, and <dev/isa/isavar.h>.

Also nuke a lot of unused and invalid headers. Some of these are audibly
provided by standard headers (namely <sys/param.h> and <sys/device.h>), some
have nothing to do with ACPI devices (e.g. <sys/syslog.h>), and some are
nonexistent local includes (e.g. "mpu_ym.h"). Moreoever, try to group the
includes into their respective blocks.

Tested with GENERIC and ALL (i386). No functional change.

Introduce support for ACPI kernel modules.

Tested on couple of laptops.

A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

branches: 1.25.2;
Add a detachment routine. While here, clarify the initialization of sensors.

Add the _COMPONENT definition for ACPI_DEBUG.

Add definitions for volume keys.

ok jmcneill@

Expand PMF_FN_* macros.

Introduce acpi_eval_set_integer().
Use it in various acpi drivers to simplify code.

XXX Is there an acpi(9) manpage?

Use deviter_first()/deviter_next() instead of accessing alldevs
directly. Compile-tested, only.

struct cfdata * -> cfdata_t, no functional changes intended.

Use aprint_debug

branches: 1.17.4;
Make the driver work (except for setting display brightness) on older
machines by removing the check for the CMOS method from thinkpad_match.
OK by jmcneill.

branches: 1.16.2; 1.16.4;

branches: 1.13.2;
Use isareg constants in thinkpad_brightness_read where possible

branches: 1.12.2;
Use PMF_FN_ARGS, PMF_FN_PROTO.

branches: 1.11.2; 1.11.6;
The Thinkpad T61/x61 family powers off the USB power resource on resume
from S3 sleep. Until we get proper ACPI power resource support, simply
call \\_SB.PCI0.LPC.EC.PUBS._ON() on resume if the method exists.

Fixes kern/37279 by Steven M Bellovin.

branches: 1.10.2;
Remove useless returns at the end of void functions.

branches: 1.9.2; 1.9.4; 1.9.6; 1.9.8;
Move display switching out of the kernel; deliver this (and other) events
to sysmon so a powerd script can handle them.

Add experimental display switching support.

Only toggle bluetooth when the wireless button is pressed, simplifies
things and it seems I forgot that my laptop has a separate wifi switch.

Add support for the WLAN / Bluetooth switch.

Hook Thinkpad temperature sensors into envsys:

$ envstat -d thinkpad0
TMP0: 46.000 degC
TMP1: 39.000 degC
TMP2: 32.000 degC
TMP3: N/A
TMP4: 50.000 degC
TMP5: N/A
TMP6: 29.000 degC
TMP7: N/A

Handle notifications in a separate thread, and ensure that the BIOS doesn't
try to play trick with us when we are trying to manage the brightness
keys.

Typo in previous.

Handle key repeat, and only match if MHKV returns an HKEY version we have
a chance of supporting.

Add Thinkpad ACPI driver, for controlling hotkeys and display brightness.

Use deviter_first()/deviter_next() instead of accessing alldevs
directly. Compile-tested, only.

struct cfdata * -> cfdata_t, no functional changes intended.

Use aprint_debug

branches: 1.17.4;
Make the driver work (except for setting display brightness) on older
machines by removing the check for the CMOS method from thinkpad_match.
OK by jmcneill.

branches: 1.16.2; 1.16.4;
Add fan sensor support, from Thomas E. Spanjaard

branches: 1.15.6;
Use 2-clause license.

Be consistent with #define<space-or-tab>.

branches: 1.13.2;
Use isareg constants in thinkpad_brightness_read where possible

branches: 1.12.2;
Use PMF_FN_ARGS, PMF_FN_PROTO.

branches: 1.11.2; 1.11.6;
The Thinkpad T61/x61 family powers off the USB power resource on resume
from S3 sleep. Until we get proper ACPI power resource support, simply
call \\_SB.PCI0.LPC.EC.PUBS._ON() on resume if the method exists.

Fixes kern/37279 by Steven M Bellovin.

branches: 1.10.2;
Remove useless returns at the end of void functions.

branches: 1.9.2; 1.9.4; 1.9.6; 1.9.8;
Move display switching out of the kernel; deliver this (and other) events
to sysmon so a powerd script can handle them.

Add experimental display switching support.

Only toggle bluetooth when the wireless button is pressed, simplifies
things and it seems I forgot that my laptop has a separate wifi switch.

Add support for the WLAN / Bluetooth switch.

Hook Thinkpad temperature sensors into envsys:

$ envstat -d thinkpad0
TMP0: 46.000 degC
TMP1: 39.000 degC
TMP2: 32.000 degC
TMP3: N/A
TMP4: 50.000 degC
TMP5: N/A
TMP6: 29.000 degC
TMP7: N/A

Handle notifications in a separate thread, and ensure that the BIOS doesn't
try to play trick with us when we are trying to manage the brightness
keys.

Typo in previous.

Handle key repeat, and only match if MHKV returns an HKEY version we have
a chance of supporting.

Add Thinkpad ACPI driver, for controlling hotkeys and display brightness.

Use acpi_compatible_match().

With the recent change of the EC address space handler, we no longer get
an ACPI_INTEGER in host byte order but a byte sized buffer with little
endian data.

Extract only the low 8 bits from buffer to get the fan speed again.

Fix undefined behavior in thinkpad_mask_init(). Found by kUBSan.

branches: 1.46.18; 1.46.24;
Split toggles for bluetooth and wwan and use specific ACPI objects
where present.
Also make driver detach on shutdown.

Update module dependencies for all the existing modules that depend on sysmon components.

branches: 1.44.12;
reverse the polarity of the extra key option, always enabling them.

Define THINKPAD_EXTENDED_HOTKEYS to enable more hotkeys on ThinkPads.
This has only been tested on a T61.
XXX: Should we put THINKPAD_EXTENDED_HOTKEYS into a opt_*.h include
(defflag) or just always enable it?

Match LEN0068 in thinkpad(4) too, as newer Thinkpads report.

Tested on a W530. Lots of stuff is missing, though.

branches: 1.41.2;
Collect rnd(9) entropy from coretemp(4), acpibat(4), aibs(4), hpacel(4),
thinkpad(4), and aps(4).

add function switch to switch on/off "wireless WAN", aka GSM et al modem
not tested to actually work, extensively tested not to do any harm if you
don't have a wwan

branches: 1.39.2; 1.39.8;
Initialize sensor state before trying to register.

Don't update the value_{min,max} - these fields are not {low,high}-water
marks, and setting them without also updating the ENVSYS_FVALID_{MIN,MAX}
flags is quite pointless.

branches: 1.37.2;
Simplify a little. No functional change.

Use the common power resource code. Also add a comment explaining
what can happen if we do not power on the resource upon resume from S3.

Use wireless function key to toggle not only bluetooth but also
telephony (GPRS/UMTS/..) like other operating systems.

Use ioconf for the module declarations.

branches: 1.33.2;
Use AcpiOsReadPort/AcpiOsWritePort instead of inb/outb so I can get rid of
of the i386 and x86_64 ifdefs.

branches: 1.32.2;
Use "temperature #" and "fan speed #" rather than "TMP#" and "FAN#" for the
sensor names. Remove white space. No functional change.

Bump WARNS to 4.

As discussed with jmcneill@, install a global "bus notification handler"
that receives all notifications and deliver notifications to drivers via it.

No need to spread the ACPICA type system any more than is necessary:

UINT8 -> uint8_t and UINT32 -> uint32_t.

branches: 1.28.2;
Remove <dev/acpi/acpica.h> from all files. It is included from
<dev/acpi/acpivar.h>. Ditto for <dev/sysmon/sysmonvar.h>, <sys/bus.h>,
<dev/pci/pcivar.h>, and <dev/isa/isavar.h>.

Also nuke a lot of unused and invalid headers. Some of these are audibly
provided by standard headers (namely <sys/param.h> and <sys/device.h>), some
have nothing to do with ACPI devices (e.g. <sys/syslog.h>), and some are
nonexistent local includes (e.g. "mpu_ym.h"). Moreoever, try to group the
includes into their respective blocks.

Tested with GENERIC and ALL (i386). No functional change.

Introduce support for ACPI kernel modules.

Tested on couple of laptops.

A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

branches: 1.25.2;
Add a detachment routine. While here, clarify the initialization of sensors.

Add the _COMPONENT definition for ACPI_DEBUG.

Add definitions for volume keys.

ok jmcneill@

Expand PMF_FN_* macros.

Introduce acpi_eval_set_integer().
Use it in various acpi drivers to simplify code.
