By Lin Ming via Len Brown: * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: ACPI: Fix D3hot v D3cold confusion 2012-05-05T05:19:52Z Lin Ming ming.m.lin@intel.com 2012-04-23T01:03:49Z urn:sha1:1cc0c998fdf2cb665d625fb565a0d6db5c81c639 Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot in some places, but D3cold in other places. After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD; and all references to D3hot use ACPI_STATE_D3_HOT. ACPI's _PR3 method is used to enter both D3hot and D3cold states. What distinguishes D3hot from D3cold is the presence _PR3 (Power Resources for D3hot) If these resources are all ON, then the state is D3hot. If _PR3 is not present, or all _PR0 resources for the devices are OFF, then the state is D3cold. This patch applies after Linux-3.4-rc1. A future syntax cleanup may remove ACPI_STATE_D3 to emphasize that it always means ACPI_STATE_D3_COLD. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Acked-by: Rafael J.

Then Dev0 is resumed first and it goes into D0 state. But Dev1 is left in D0_Uninitialised state. This is wrong. In this case, Dev1 must be resumed too. In order to hand this case, each power resource maintains a list of devices which relies on it. When power resource is ON, it will check if the devices on its list can be resumed. The device can only be resumed when all the power resouces of its _PR0 are ON.

Windows apparently does not execute these methods, and therefore these methods are often untested. It has been seen on some systems where the execution of these methods causes errors and also prevents the machine from entering S5. It is therefore suggested that host operating systems do not execute these methods by default. In the future, perhaps these methods can be optionally executed based on the age of the system and/or what is the newest version of Windows that the BIOS asks for via _OSI.
