So that we only have the following functions to be used externally: early_acpi_osi_init(): Used by DMI detections; acpi_osi_init(): Used to initialize OSI command line settings and install Linux specific _OSI handler; acpi_osi_setup(): The API that should be used by the external quirks. acpi_osi_is_win8(): The API is used by the external drivers to determine if BIOS supports Win8.

2015-07-03ACPI / init: Make it possible to override _REVRafael J. Wysocki1-0/+26
The platform firmware on some systems expects Linux to return "5" as the supported ACPI revision which makes it expose system configuration information in a special way. For example, based on what ACPI exports as the supported revision, Dell XPS 13 (2015) configures its audio device to either work in HDA mode or in I2S mode, where the former is supposed to be used on Linux until the latter is fully supported (in the kernel as well as in user space). Since ACPI 6 mandates that _REV should return "2" if ACPI 2 or later is supported by the OS, a subsequent change will make that happen, so make it possible to override that on systems where "5" is expected to be returned for Linux to work correctly one them (such as the Dell machine mentioned above).

2014-07-21ACPI: move models with win8 brightness problems from win8 blacklist to ↵Hans de Goede1-66/+2
use_native_backlight When the windows8 related backlight problems became evident, 2 approaches were follow in parallel, one was to stop claiming to be windows 8 / 2012, the other was to tell acpi_video to stop registering a backlight driver. I've read all the threads and it seems that which approach ended up being applied to which model laptop was never really a concious decision (AFAIK): https://bugzilla.kernel.org/show_bug.cgi?id=51231 https://bugzilla.kernel.org/show_bug.cgi?id=60682 So lets move all the models which are only on the win8 blacklist because of brightness issues to the use_native_backlight list, which is the smaller hammer to use to solve the backlight issues. Making this change is esp. attractive now that 3.16 has video.use_native_brightness=1 by default. If that new default does not get reverted because of regressions, then we can drop all the models with a use_native_backlight quirk, greatly reducing the number of models we've a quirk for.

Some system's ACPI video backlight control interface is broken and the native backlight control interface should be used by default. This patch sets the use_native_backlight parameter to true for those systems so that video backlight control interface will not be created. For detailed models that are added here, reference the following list. Note that the user specified kernel cmdline option will always have the highest priority, i.e. if use_native_backlight=0 is specified and the system is in the DMI table, the video module will not skip registering backlight interface for it.

2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng1-1/+0
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

About 10 years ago, this option was created to help distros enable ACPI and not get distracted by ACPI BIOS issues in machines which were deemed old at that time, eg 1999 and earlier. After a couple of years, the high volume distros stopped bothering to set this option, and instead simply ran in ACPI mode on all systems with an ACPI BIOS -- regardless of BIOS DMI year. Recently there have been some ACPI-enabled systems with no DMI, mandating that CONFIG_ACPI_BLACKLIST_YEAR=0. So it seems vanishingly unlikely that this option is helping anybody run a 2013 kernel on a 1998 system, and now more systems mandate this option be disabled, so we simplify by deleting it entirely.

2013-08-25ACPI: blacklist win8 OSI for buggy laptopsFelipe Contreras1-0/+16
Since v3.7 the acpi backlight driver doesn't work correctly in several machines because ACPI code has different code for Windows 8, and the rest. The commit ea45ea7 (in v3.11-rc2) tried to fix this problem by using the intel backlight driver, however it introduced several other issues in different machines. This patch fixes both regressions by blacklisting the win8 OSI, so we are back to v3.6 behavior, and it should remain that way until the intel backlight driver is fixed. Since v3.7, users have been forced to fix the initial regression by modifying the boot arguments (acpi_osi="!Windows 2012"). Once the Intel backlight driver works correctly for all machines, this blacklist can be removed and that driver can be used instead.

Since v3.7 the ACPI backlight driver doesn't work at all on this machine, because presumably the backlight AML code in the ACPI tables contains a code path that triggers when the OS identifies itself as compatible with Windows 8 (which the kernel started to do in 3.7). That code path is never used by Windows and on this particular machine it turns out to be unusable at all. Work around this problem by blacklisting the win8 OSI, so we are back to v3.6 behavior (that is, we don't tell the BIOS that we are compatible with Windows 8).

Disable Vista compatibility for Sony VGN-NS50B_L. https://bugzilla.kernel.org/show_bug.cgi?id=12904#c46 Note that this change is a workaround, not a permanent fix. For the permanent fix is to figure out what compatibility means and to actually be compatible...

2009-12-22ACPI: disable _OSI(Windows 2009) on Asus K50IJZhang Rui1-0/+14
Fix a win7 compability issue on Asus K50IJ. Here is the _BCM method of this laptop: Method (_BCM, 1, NotSerialized) { If (LGreaterEqual (OSFG, OSVT)) { If (LNotEqual (OSFG, OSW7)) { Store (One, BCMD) Store (GCBL (Arg0), Local0) Subtract (0x0F, Local0, LBTN) ^^^SBRG.EC0.STBR () ... } Else { DBGR (0x0B, Zero, Zero, Arg0) Store (Arg0, LBTN) ^^^SBRG.EC0.STBR () ... } } } LBTN is used to store the index of the brightness level in the _BCL. GCBL is a method that convert the percentage value to the index value. If _OSI(Windows 2009) is not disabled, LBTN is stored a percentage value which is surely beyond the end of _BCL package. http://bugzilla.kernel.org/show_bug.cgi?id=14753 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-09-09dmi: extend dmi_get_year() to dmi_get_date()Tejun Heo1-2/+3
There are cases where full date information is required instead of just the year. Add month and day parsing to dmi_get_year() and rename it to dmi_get_date(). As the original function only required '/' followed by any number of parseable characters at the end of the string, keep that behavior to avoid upsetting existing users. The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month and date are checked to be in the ranges of [1-9999], [1-12] and [1-31] respectively and any invalid or out-of-range component is returned as zero. The dummy implementation is updated accordingly but the return value is updated to indicate field not found which is consistent with how other dummy functions behave.

2009-08-29ACPI: Move definition of PREFIX from acpi_bus.h to internal..hLen Brown1-0/+2
Linux/ACPI core files using internal.h all PREFIX "ACPI: ", however, not all ACPI drivers use/want it -- and they should not have to #undef PREFIX to define their own. Add GPL commment to internal.h while we are there. This does not change any actual console output, asside from a whitespace fix. Signed-off-by: Len Brown <len.brown@intel.com>
