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.
- make sure that the driver checks the battery presence at acpibat_update()
if the battery has been not present, because the driver sometimes
(i.e. boot time or resuming time) miss to sense the presence.
- make sure that the driver always update the status at acpibat_gtredata();
I misunderstood about ACPI_NOTIFY_BatteryStatusChanged event.
it is very slow to access to EC on some machines (i.e. CASIO FIVA 2xx).
- clean the flags up.
- add locks while updating informations.
- some cosmetic changes.
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.
unless ACPI_FDC_DEBUG
array returned from _FDE contains UINT32 values, not UINT8; also change
the magic number '14' to '5 * sizeof(UINT32)' for clarity
remove XXX for the tape presence comment; it's Just Okay to not use the info
fdc_acpi_getknownfds(): if fdc_acpi_nvtotype() returns NULL, don't
attempt to attach the drive at all
XXX not tested
* 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.
