[PATCH] off-by-1 in kernel/power/main.c

2006-04-28T15:33:46+00:00

There's an off-by-1 in kernel/power/main.c:state_store() ...  if your
kernel just happens to have some non-zero data at pm_states[PM_SUSPEND_MAX]
(i.e.  one past the end of the array) then it'll let you write anything you
want to /sys/power/state and in response the box will enter S5.

[PATCH] swsusp: add s2ram ioctl to userland interface

2006-03-23T15:38:08+00:00

Add the SNAPSHOT_S2RAM ioctl to the snapshot device.

This ioctl allows a userland application to make the system (previously frozen
with the SNAPSHOT_FREE ioctl) enter the S3 state without freezing processes
and disabling nonboot CPUs for the second time.

This will allow us to implement the suspend-to-disk-and-RAM (STDR)
functionality in the userland suspend tools.

[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.

[ACPI] Suspend to RAM fix

2005-07-12T03:21:54+00:00

Free some RAM before entering S3 so that upon
resume we can be sure early allocations will succeed.
