- 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.
on the original approach of SVR4 with some inspirations about balancing
and migration from Solaris. It implements per-CPU runqueues, provides a
real-time (RT) and time-sharing (TS) queues, ready to support a POSIX
real-time extensions, and also prepared for the support of CPU affinity.
The following lines in the kernel config enables the SCHED_M2:
no options SCHED_4BSD
options SCHED_M2
The scheduler seems to be stable. Further work will come soon.

Thanks <ad> for the benchmarks!
sensors (those that contain the 'want-percentage' object on its
dictionary), the 'critical-capacity' prop must be used instead.
- When setting a 'critical-{max,min}' property check if the value is
higher than the 'max-value' or lower than the 'min-value' on its
dictionary, raise an error if it's true.
The issue seems to have been present for some time, only showed up
when running unit-tests on SunOS.
Make sure we get an error message, but otherwise behave as before.
- Replace most panic() checks with KASSERT();
- msgrcv1: Improve readability;
- Remove #ifdef ENOMSG;
No function changes of the interface are intented.
- include <stdbool.h> so bool is available _KERNEL for sys/condvar.h
- include <sys/mutex.h> before defining _KERNEL so it won't try to
include <machine/intr.h> which isn't available to userland.
fixes builds on sparc64.
