config_found_ia on the node to save a bunch of useless 'device NNN
not configured' messages at startup. While here, condense ACPI printfs
at attach time.
the same value! Fixes the AE_AML_MUTEX_NOT_ACQUIRED issue when evaluating
_BST on ASUS Eee PC. Who knows what other mysterious bugs this has caused
over the years...
All Reference Objects returned via the AcpiEvaluateObject interface are now
marked as type "REFERENCE" instead of "ANY". The type ANY is now reserved for
NULL objects - either NULL package elements or unresolved named references.
to always fetch new status after resuming, otherwise if AACAD_F_AVAILABLE
is set, acpiacad_get_status() won't be called.
Also use the SME_INIT_REFRESH flag to fetch sensor data once in the
autoconf(9) process.
Ok'ed by <jmcneill>.
Improve PMF-ability.
Add a 'flags' argument to suspend/resume handlers and
callers such as pmf_system_suspend().
Define a flag, PMF_F_SELF, which indicates to PMF that a
device is suspending/resuming itself. Add helper routines,
pmf_device_suspend_self(dev) and pmf_device_resume_self(dev),
that call pmf_device_suspend(dev, PMF_F_SELF) and
pmf_device_resume(dev, PMF_F_SELF), respectively. Use
PMF_F_SELF to suspend/resume self in ath(4), audio(4),
rtw(4), and sip(4).
In ath(4) and in rtw(4), replace the icky sc_enable/sc_disable
callbacks, provided by the bus front-end, with
self-suspension/resumption. Also, clean up the bus
front-ends. Make sure that the interrupt handler is
disestablished during suspension. Get rid of driver-private
flags (e.g., RTW_F_ENABLED, ath_softc->sc_invalid); use
device_is_active()/device_has_power() calls, instead.
In the network-class suspend handler, call if_stop(, 0)
instead of if_stop(, 1), because the latter is superfluous
(bus- and driver-suspension hooks will 'disable' the NIC),
and it may cause recursion.
In the network-class resume handler, prevent infinite
recursion through if_init() by getting out early if we are
self-suspending (PMF_F_SELF).
rtw(4) improvements:
Destroy rtw(4) callouts when we detach it. Make rtw at
pci detachable. Print some more information with the "rx
frame too long" warning.
Remove activate() methods:
Get rid of rtw_activate() and ath_activate(). The device
activate() methods are not good for much these days.
Make ath at cardbus resume with crypto functions intact:
Introduce a boolean device property, "pmf-powerdown". If
pmf-powerdown is present and false, it indicates that a
bus back-end should not remove power from a device.
Honor this property in cardbus_child_suspend().
Set this property to 'false' in ath_attach(), since removing
power from an ath at cardbus seems to lobotomize the WPA
crypto engine. XXX Should the pmf-powerdown property
propagate toward the root of the device tree?
Miscellaneous ath(4) changes:
Warn if ath(4) tries to write crypto keys to suspended
hardware.
Reduce differences between FreeBSD and NetBSD in ath(4)
multicast filter setup.
Make ath_printrxbuf() print an rx descriptor's status &
key index, to help debug crypto errors.
Shorten a staircase in ath_ioctl(). Don't check for
ieee80211_ioctl() return code ERESTART, it never happens.
Add a method for detaching children. XXX acpi(4) may leak some
resources for each child detached. Needs attention from someone
who understands acpi(4).
except the ppbus stuff (which doesn't compile) and ulpt(4) which is
unrelated and can be dealt with separately.
As usual, it comes with related cosmetic changes.
