2009-01-09ACPI : Use RSDT instead of XSDT by adding boot option of "acpi=rsdt"Zhao Yakui5-2/+10
On some boxes there exist both RSDT and XSDT table. But unfortunately sometimes there exists the following error when XSDT table is used: a. 32/64X address mismatch b. The 32/64X FACS address mismatch In such case the boot option of "acpi=rsdt" is provided so that RSDT is tried instead of XSDT table when the system can't work well. http://bugzilla.kernel.org/show_bug.cgi?id=8246 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> cc:Thomas Renninger <trenn@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
2009-01-09ACPI: Avoid array address overflow when _CST MWAIT hint bits are setZhao Yakui1-1/+3
The Cx Register address obtained from the _CST object is used as the MWAIT hints if the register type is FFixedHW. And it is used to check whether the Cx type is supported or not. On some boxes the following Cx state package is obtained from _CST object: >{ ResourceTemplate () { Register (FFixedHW, 0x01, // Bit Width 0x02, // Bit Offset 0x0000000000889759, // Address 0x03, // Access Size ) }, 0x03, 0xF5, 0x015E } In such case we should use the bit[7:4] of Cx address to check whether the Cx type is supported or not. mask the MWAIT hint to avoid array address overflow Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by:Venki Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-01-09fujitsu-laptop: Simplify SBLL/SBL2 backlight handlingTony Vroon1-93/+21
GBLS and GBLL only differ in the clearing of the GHKS flag, so there is no need to have two backlight level readouts. 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.

2009-01-09fujitsu-laptop: Add BL power, LED control and radio state informationTony Vroon1-33/+272
The FUNC interface in the Fujitsu-Siemens DSDT was unused until now. It exposes state information that is now reported in additional platform files (whether the radios are killed by the hardware switch or operational, whether the machine is docked and whether the lid is open). 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.

2008-12-31ACPICA: FADT: set acpi_gbl_use_default_register_widths to TRUE by defaultrobert.moore@intel.com2-69/+106
This returns the FADT support to the original behavior, which is to use default register widths. However, now check each register definition and report a warning if it differs from the default. This is a first step to moving away from the default widths, rather than outright believing the widths in all FADTs for all machines, considered rather dangerous until more data is obtained.

2008-12-31ACPICA: FADT parsing changes and fixesBob Moore3-21/+118
1) Update the register lengths for the PM1 event blocks. The length must be divided by two in order to use these to access the status registers. 2) Add run-time option to use default register lengths to override a faulty FADT. 3) Add warning message if any of the X64 address structures contain a length that does not match the legacy length earlier in the FADT. 4) Move all FADT warning messages into the ValidateFadt function.

2008-12-31ACPICA: Restructure includes into public/privateBob Moore123-673/+980
acpi.h now includes only the "public" acpica headers. All other acpica headers are "private" and should not be included by acpica users. One new file, accommon.h is used to include the commonly used private headers for acpica code generation. Future plans are to move all private headers to a new subdirectory.

2008-12-31ACPICA: New: acpi_read and acpi_write public interfacesBob Moore7-126/+89
Changed the acpi_hw_low_level_read and acpi_hw_low_level_write functions to the public acpi_read and acpi_write to allow direct access to ACPI registers. 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.

2008-12-30ACPI: Do not modify SCI_EN directlyRafael J. Wysocki1-4/+0
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).

Add decaying history of predicted idle time, instead of using the last early wakeup. This logic helps menu governor do better job of predicting idle time. With this change, we also measured noticable (~8%) power savings on a DP server system with CPUs supporting deep C states, when system was lightly loaded.
