| * Hibernate: Take overlapping zones into account (rev. 2)Rafael J. Wysocki2008-12-191-159/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been requested to make hibernation work with memory hotplugging enabled and for this purpose the hibernation code has to be reworked to take the possible overlapping of zones into account. Thus, rework the hibernation memory bitmaps code to prevent duplication of PFNs from occuring and add checks to make sure that one page frame will not be marked as saveable many times. Additionally, use list.h lists instead of open-coded lists to implement the memory bitmaps. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>
| * Hibernate: Do not oops on resume if image data are incorrectRafael J. Wysocki2008-12-191-11/+32
| | | | | | | | | | | | | | | | | | | | | | | | During resume from hibernation using the userland interface image data are being passed from the used space process to the kernel. These data need not be valid, but currently the kernel sometimes oopses if it gets invalid image data, which is wrong. Make the kernel return error codes to the user space in such cases.

| * ACPI hibernate: Add a mechanism to save/restore ACPI NVS memoryRafael J. Wysocki2008-12-193-8/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the ACPI Specification 3.0b, Section 15.3.2, "OSPM will call the _PTS control method some time before entering a sleeping state, to allow the platform's AML code to update this memory image before entering the sleeping state. After the system awakes from an S4 state, OSPM will restore this memory area and call the _WAK control method to enable the BIOS to reclaim its memory image." For this reason, implement a mechanism allowing us to save the NVS memory during hibernation and to restore it during the subsequent resume. Based on a patch by Zhang Rui. Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the ACPI specification the SCI_EN flag is controlled by the hardware, which sets this flag to inform the kernel that ACPI is enabled. For this reason, we shouldn't try to modify SCI_EN directly. Also, we don't need to do it in irqrouter_resume(), since lower-level resume code takes care of enabling ACPI in case it hasn't been enabled by the BIOS before passing control to the kernel (which by the way is against the ACPI specification).

Also, per Peter Gruber, the need for the BLNF check has disappeared. As a result, cleanups can be made in the code. This has been tested on the both the S6410 and the S6420 platforms and causes no functionality regressions, on the console without X or within X. One module parameter to disable the hotkeys is dropped, as we only ever took one codepath anyway.

Support for the backlight class is now extended with the ability to power the backlight on & off. Optional support for the LED class allows the keyboard headlamps found on the U810 netbook and the Fujitsu logo illumination on the P8010 notebook to be turned on & off. This was fed through checkpatch.pl and tested on the S6420, P8010 & U810 platforms.

However, if an MP Table is was found, IRQs will be registered as if an IOAPIC is being used, even though ACPI is configuring interrupt links links for PIC mode. In this scenario, disable MPS so that IRQs are registered in PIC mode, consistent with ACPI. http://bugzilla.kernel.org/show_bug.cgi?id=12257 Signed-off-by: Len Brown <len.brown@intel.com>

At least ThinkPad SL300 (and probably all IdeaPads) returns the array reversed (i.e. bightest levels have lowest indexes), which causes the brightness management behave in completely reversed manner on these machines (brightness increases when the laptop is idle, while the display dims when used). Sorting the array by brightness level values after reading the list fixes the issue. http://bugzilla.kernel.org/show_bug.cgi?id=12037 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Tested-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Len Brown <len.brown@intel.com>

* | | | | | | ACPICA: New: acpi_reset interface - write to reset registerBob Moore2008-12-312-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Uses the FADT-defined reset register and reset value. Checks the FADT flags for the reset register supported bit. Supports reset register in memory or I/O space, but not in PCI config space since the host has the information to do it.

Removed the "width" parameter since the width can be obtained from the input GAS structure. Updated the FADT initialization to setup the GAS structures with the proper widths. Some widths are still hardcoded because many FADTs have incorrect register lengths.
