ACPI: do acpisleep dmi check when CONFIG_ACPI_SLEEP is set

2012-11-30T11:57:03+00:00

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. [rjw: Added acpi_sleep_dmi_check() and rebased on top of earlier patches adding entries to acpisleep_dmi_table[].] References: https://bugzilla.kernel.org/show_bug.cgi?id=45921 Signed-off-by: Zhang Rui Cc: Signed-off-by: Rafael J.

ACPI / PM: Add Sony Vaio VPCEB1S1E to nonvs blacklist.

Sony Vaio VPCEB1S1E does not resume correctly without acpi_sleep=nonvs, so add it to the ACPI sleep blacklist. References: https://bugzilla.kernel.org/show_bug.cgi?id=48781 Reported-by: Sébastien Wilmet Cc: Signed-off-by: Lan Tianyu Signed-off-by: Rafael J. Wysocki

ACPI / Sleep: add acpi_sleep=nonvs_s3 parameter

2012-11-14T23:16:02+00:00

The ACPI specificiation would like us to save NVS at hibernation time, but makes no mention of saving NVS over S3. Not all versions of Windows do this either, and it is clear that not all machines need NVS saved/restored over S3. Allow the user to improve their suspend/resume time by disabling the NVS save/restore at S3 time, but continue to do the NVS save/restore for S4 as specified.

ACPI / PM: Move device PM functions related to sleep states

2012-11-14T23:15:18+00:00

Introduce helper function returning the target sleep state of the system and use it to move the remaining device power management functions from sleep.c to device_pm.c. Signed-off-by: Rafael J. Wysocki

ACPI / PM: Split device wakeup management routines

2012-11-14T23:15:17+00:00

Two device wakeup management routines in device_pm.c and sleep.c, acpi_pm_device_run_wake() and acpi_pm_device_sleep_wake(), take a device pointer argument and use it to obtain the ACPI handle of the corresponding ACPI namespace node. That handle is then used to get the address of the struct acpi_device object corresponding to the struct device passed as the argument. Unfortunately, that last operation may be costly, because it involves taking the global ACPI namespace mutex, so it shouldn't be carried out too often. However, the callers of those routines usually call them in a row with acpi_pm_device_sleep_state() which also takes that mutex for the same reason, so it would be more efficient if they ran acpi_bus_get_device() themselves to obtain a pointer to the struct acpi_device object in question and then passed that pointer to the appropriate PM routines. To make that possible, split each of the PM routines mentioned above in two parts, one taking a struct acpi_device pointer argument and the other implementing the current interface for compatibility. Additionally, change acpi_pm_device_run_wake() to actually return an error code if there is an error while setting up runtime remote wakeup for the device. Signed-off-by: Rafael J. Wysocki

ACPI / PM: Move runtime remote wakeup setup routine to device_pm.c

2012-11-14T23:15:17+00:00

The ACPI function for setting up devices to do runtime remote wakeup is now located in drivers/acpi/sleep.c, but drivers/acpi/device_pm.c is a more logical place for it, so move it there. No functional changes should result from this modification. Signed-off-by: Rafael J. Wysocki

ACPI / PM: Move device power state selection routine to device_pm.c

2012-11-14T23:15:16+00:00

The ACPI function for choosing device power state is now located in drivers/acpi/sleep.c, but drivers/acpi/device_pm.c is a more logical place for it, so move it there. However, instead of moving the function entirely, move its core only under a different name and with a different list of arguments, so that it is more flexible, and leave a wrapper around it in the original location.
