Hi,
This set of patches reworks the handling of system wakeup interrupts so that
suspend-to-idle is covered in the same way as full system suspend.
This time we have several new patches from Thomas and hopefully we're nailed
down that thing at last.
[01/13] Mechanism to wake up the system or abort suspend in progress
automatically (this is different from the previous versions, because
I eventually convinced myself that pm_abort_suspend didn't really
require any locking).
[02/13] Move PM-related IRQ code to kernel/irq/pm.c.
[03/13] Add accounting for IRQF_NO_SUSPEND and IRQF_RESUME_EARLY.
[04/13] Use the accoundint added by [03/13].
[05/13] Make suspend_device_irqs() mask non-wakeup interruts if
IRQCHIP_MASK_ON_SUSPEND is set.
[06/13] Synchronize IRQs in the same loop in which they are reconfigured
in suspend_device_irqs().
[07/13] Separate irq_check_poll() checks from disabled/no action checks in
kernel/irq/chip.c.
[08/13] Add a helper for checks made by many IRQ flow handlers in the same way.
[09/13] Mark wakeup sources as "armed" on suspend (using a new flag).
[10/13] Make suspend_device_irqs() leave wakeup interrupts enabled, but handle
them so that the first interrupt triggers system wakeup.
[11/13] Set IRQCHIP_SKIP_SET_WAKE for x86 IOAPIC IRQ chips (same as before).
[12/13] Make PCIe PME wake up from suspend to idle (same as before).
[13/13] Document rules related to system suspend and interrupts (updated).
The series have been tested on MSI Wind, but more testing is welcome.
There is a pm-genirq branch in the linux-pm.git tree containing these patches:
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm-genirq
that can be pulled from.
Kind regards,
Rafael
