Subject: [PATCH 3/5 v3] x86 / PM: Set IRQCHIP_SKIP_SET_WAKE for IOAPIC IRQ chip objects
Date: Wed, 27 Aug 2014 01:50:49 +0200 [thread overview]
Message-ID: <5572679.hklRpx9fCZ@vostro.rjw.lan> (raw)
In-Reply-To: <5320472.coYotHR1d0@vostro.rjw.lan>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Set the IRQCHIP_SKIP_SET_WAKE for IOAPIC IRQ chip objects so that
interrupts from them can work as wakeup interrupts for suspend-to-idle.
After this change, running enable_irq_wake() on one of the IRQs in
question will succeed and IRQD_WAKEUP_STATE will be set for it, so
all of the suspend-to-idle wakeup mechanics introduced previously
will work for it automatically.
