ACPI: do acpisleep dmi check when CONFIG_ACPI_SLEEP is set 2013-01-11T17:06:54+00:00 Zhang Rui rui.zhang@intel.com 2012-11-30T11:57:03+00:00 dc2306834bff03132beb1f18d7a13b6e5080e488 commit 0ac1b1d7b7424cd6f129b5454b504b3cae746f0e upstream. The current acpisleep DMI checks only run when CONFIG_SUSPEND is set. And this may break hibernation on some platforms when CONFIG_SUSPEND is cleared.

The current acpisleep DMI checks only run when CONFIG_SUSPEND is set.
And this may break hibernation on some platforms when CONFIG_SUSPEND
is cleared.

Move acpisleep DMI check into #ifdef CONFIG_ACPI_SLEEP instead.

The comparison between the system sleep state being entered and the lowest system sleep state the given device may wake up from in acpi_pm_device_sleep_state() is reversed, because the specification (ACPI 5.0) says that for wakeup to work: "The sleeping state being entered must be less than or equal to the power state declared in element 1 of the _PRW object." In other words, the state returned by _PRW is the deepest (lowest-power) system sleep state the device is capable of waking up the system from. Moreover, acpi_pm_device_sleep_state() also should check if the wakeup capability is supported through ACPI, because in principle it may be done via native PCIe PME, for example, in which case _SxW should not be evaluated.

commit dbe9a2edd17d843d80faf2b99f20a691c1853418 upstream.

The comparison between the system sleep state being entered
and the lowest system sleep state the given device may wake up
from in acpi_pm_device_sleep_state() is reversed, because the
specification (ACPI 5.0) says that for wakeup to work:

"The sleeping state being entered must be less than or equal to the
 power state declared in element 1 of the _PRW object."

In other words, the state returned by _PRW is the deepest
(lowest-power) system sleep state the device is capable of waking up
the system from.

Moreover, acpi_pm_device_sleep_state() also should check if the
wakeup capability is supported through ACPI, because in principle it
may be done via native PCIe PME, for example, in which case _SxW
should not be evaluated.

ACPI: Convert wake_sleep_flags to a value instead of function 2012-04-23T20:29:07+00:00 Konrad Rzeszutek Wilk konrad.wilk@oracle.com 2012-04-23T03:03:17+00:00 2a14e541ed87bca0c125b82961ca3c6f808607d2 With commit a2ef5c4fd44ce3922435139393b89f2cce47f576 "ACPI: Move module parameter gts and bfs to sleep.c" the wake_sleep_flags is required when calling acpi_enter_sleep_state, which means that if there are functions outside the sleep.c code they can't get the wake_sleep_flags values.

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.
