2009-04-19PM/Suspend: Introduce two new platform callbacks to avoid breakageRafael J. Wysocki1-4/+4
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.

2009-04-17ACPI: Disable _GTS and _BFS support by defaultLen Brown1-0/+27
Executing BIOS code paths not exercised by Windows tends to get Linux into trouble. However, if a system does benefit from _GTS or _BFS, acpi.gts=1 an acpi.bfs=1 are now available to enable them. http://bugzilla.kernel.org/show_bug.cgi?id=13041 Signed-off-by: Len Brown <len.brown@intel.com>

2009-03-26ACPICA: Rename ACPI bit register access functionsBob Moore1-1/+1
Rename acpi_get_register and acpi_set_register to clarify the purpose of these functions. New names are acpi_read_bit_register and acpi_write_bit_register. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-03-17ACPI: move private declarations to internal.hBjorn Helgaas1-0/+2
A number of things that shouldn't be exposed outside the ACPI core were declared in include/acpi/acpi_drivers.h, where anybody can see them. This patch moves those declarations to a new "internal.h" inside drivers/acpi. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

Switch the Asus Pundit P1-AH2 (M2N8L motherboard) to the old ACPI 1.0 sleep ordering by default. Without this it will not suspend/resume correctly. Signed-off-by: Andy Whitcroft <apw@canonical.com> Tested-by: Dustin Kirkland <kirkland@canonical.com> Signed-off-by: Len Brown <len.brown@intel.com>
