[ACPI] SMP S3 resume: evaluate _WAK after INIT

2005-12-01T04:15:55+00:00

On SMP resume from S3, we reset (INIT) the non-boot
processors to boot them cleanly.  But the BIOS needs
to execute _WAK after INIT in order to properly
initialized these processors upon resume.

[PATCH] fix swsusp on machines not supporting S4

2005-11-30T03:47:03+00:00

Fix swsusp on machines not supporting S4.  With recent changes, it is not
possible to trigger it using /sys filesystem.  Swsusp does not really need
any support from low-level code, it is possible to reboot or halt at the
end of suspend.

[PATCH] sleep: Fix oops in enter_state

2005-11-09T15:55:50+00:00

If ACPI sleep is not configured, but someone still wants to run swsusp,
he'd get oops in enter_state.  This is regression since 2.6.14 and this
fixes it.

[PATCH] introduce .valid callback for pm_ops

2005-10-31T01:37:15+00:00

Add pm_ops.valid callback, so only the available pm states show in
/sys/power/state.  And this also makes an earlier states error report at
enter_state before we do actual suspend/resume.

Using CPU hotplug to support suspend/resume SMP.  Both S3 and S4 use
disable/enable_nonboot_cpus API.  The S4 part is based on Pavel's original S4
SMP patch.

[PATCH] Driver Core: pm diagnostics update, check for errors

2005-05-17T21:54:54+00:00

This patch includes various tweaks in the messaging that appears during
system pm state transitions:

  * Warn about certain illegal calls in the device tree, like resuming
    child before parent or suspending parent before child.  This could
    happen easily enough through sysfs, or in some cases when drivers
    use device_pm_set_parent().

  * Be more consistent about dev_dbg() tracing ... do it for resume() and
    shutdown() too, and never if the driver doesn't have that method.

  * Say which type of system sleep state is being entered.

Except for the warnings, these only affect debug messaging.
