which gives problems with PCI bus finding; the object hierarchy doesn't
match the real world for some systems, most notably SuperMicro boards.
Linux has this one blacklisted as well.
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.
the kernel config file. That code makes a total mess of any
system with multiple PCI busses.
* Rework the way buttons are handled; register them with sysmon,
and let it take the appropriate action. This lets us gracefully
shut down when the power button is pressed.
acpi_is_global_locked() functions.
AcpiGlobalLock() API should be used to acquire lock between BIOS and OS.
This API cannot be used to lock between threads of the OS side,
because this function immediately returns if the lock is already acquired
by the OS. c.f. AcpiEvAcquireGlobalLock()@evmisc.c
- make sure that acpiec driver uses above functions.
- use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(),
in acpi_eval_string()/acpi_eval_struct().
Twice AcpiEvaluateObject() calls may cause twice side effects
to ACPI machine / hardware and this may be wrong in some cases.
* Improve acpi interrupt fixup a bit
* Source is an array, don't compare it to NULL, instead
look for an empty string to denote a link-device-less
entry.
* For root PCI busses, try to use the _BBN method to get
numbering right.
* Add acpi_md_callback() function for MD handling after the init,
but before * at acpi probing.
#if 0-out a half-fixed acpi_eval_string() and #if 0 the only call to it.
(Previous code referenced an uninitialized local variable and couldn't
have possibly worked).
- In acpi_print(), try to evaluate the _STR object, and print
it if the device is not configured.
- Make this compile without ACPI_DEBUG, from Masanori Kanaoka.
