2006-04-28[PATCH] off-by-1 in kernel/power/main.cdean gaudet1-1/+1
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.

2006-03-23[PATCH] swsusp: add s2ram ioctl to userland interfaceLuca Tettamanti1-1/+1
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. Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Signed-off-by: Rafael J.

2005-11-30[ACPI] SMP S3 resume: evaluate _WAK after INITDavid Shaohua Li1-2/+2
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. http://bugzilla.kernel.org/show_bug.cgi?id=5651 Signed-off-by: David Shaohua Li <shaohua.li@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2005-11-29[PATCH] fix swsusp on machines not supporting S4Pavel Machek1-5/+16
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.

2005-11-09[PATCH] sleep: Fix oops in enter_statePavel Machek1-1/+1
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. Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-30[PATCH] introduce .valid callback for pm_opsShaohua Li1-1/+4
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.

2005-06-25[PATCH] suspend/resume SMP supportLi Shaohua1-6/+10
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. Signed-off-by: Li Shaohua<shaohua.li@intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-17[PATCH] Driver Core: pm diagnostics update, check for errorsDavid Brownell1-3/+3
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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+269
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
