yamt 44d0d57217 do wakeup() only when someone is waiting for us. 2003-08-11 15:07:14 +00:00
yamt 104f2a80df introduce SME_FLAG_BUSY and set it during operations
instead of keeping sysmon_envsys_list_slock spinlock held
because some drivers might sleep in sysmon_envsys ops,

XXX sysmon_envsys_lock is now redundant

fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
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

thorpej 5a20f4be3c * Add a generic power management event API, defined in <sys/power.h>.
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.

thorpej b0f79c65ce Start at a power management framework for sysmon. Right now we just
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.

thorpej a5bb7e6494 Group things in this file a bit more logically. 2003-04-10 18:04:20 +00:00
thorpej e67f5e66bc Split the envsys and watchdog parts of sysmon into their own
files.

thorpej c48d521bdb Add a watchog timer framework to the system monitor. 2000-11-04 18:37:19 +00:00
thorpej f82e306928 Add a clearing-house pseudo-device for system monitoring devices
such as the LM78 and VT82C686A (and eventually ACPI).  Multiple
sensor devices can be hooked registered with `sysmon', and eventually
sysmon will also handle hardware (and software) watchdog timers.

Convert the `lm' and `viaenv' drivers to the new interface.
