2009-12-30ACPI: introduce kernel parameter acpi_sleep=sci_force_enableZhang Rui
Introduce kernel parameter acpi_sleep=sci_force_enable some laptop requires SCI_EN being set directly on resume, or else they hung somewhere in the resume code path. We already have a blacklist for these laptops but we still need this option, especially when debugging some suspend/resume problems, in case there are systems that need this workaround and are not yet in the blacklist.

2009-09-09PCI / ACPI PM: Propagate wake-up enable for devices w/o ACPI supportRafael J. Wysocki
Some PCI devices (not PCI Express), like PCI add-on cards, can generate PME#, but they don't have any special platform wake-up support. For this reason, even if they generate PME# to wake up the system from a sleep state, wake-up events are not generated by the platform. It turns out that, at least on some systems, PCI bridges and the PCI host bridge have ACPI GPEs associated with them that, if enabled to generate wake-up events, allow the system to wake up if one of the add-on devices asserts PME# while the system is in a sleep state. Following this observation, if a PCI device without direct ACPI wake-up support is prepared to wake up the system during a transition into a sleep state (eg. suspend to RAM), try to configure the bridges on the path from the device to the root bridge to wake-up the system.

2009-04-19PM/Suspend: Introduce two new platform callbacks to avoid breakageRafael J. Wysocki
Commit 900af0d973856d6feb6fc088c2d0d3fde57707d3 (PM: Change suspend code ordering) changed the ordering of suspend code in such a way that the platform .prepare() callback is now executed after the device drivers' late suspend callbacks have run. Unfortunately, this turns out to break ARM platforms that need to talk via I2C to power control devices during the .prepare() callback. For this reason introduce two new platform suspend callbacks, .prepare_late() and .wake(), that will be called just prior to disabling non-boot CPUs and right after bringing them back on line, respectively, and use them instead of .prepare() and .finish() for ACPI suspend. Make the PM core execute the .prepare() and .finish() platform suspend callbacks where they were executed previously (that is, right after calling the regular suspend methods provided by device drivers and right before executing their regular resume methods, respectively). It is not necessary to make analogous changes to the hibernation code and data structures at the moment, because they are only used by ACPI platforms. Signed-off-by: Rafael J.
