Rafael J. Wysocki a6940190ac Revert "ACPI: Blacklist Win8 OSI for some HP laptop 2013 models"
This reverts commit 2d4054d842 (ACPI: Blacklist Win8 OSI for some HP
laptop 2013 models) that is not necessary any more after previous
commit 1811fcb029fa (ACPI / video: Add systems that should favour native
backlight interface).

Aaron Lu 0e9f81d3b7 ACPI / video: Add systems that should favour native backlight interface
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.

Takashi Iwai 2d4054d842 ACPI: Blacklist Win8 OSI for some HP laptop 2013 models
The BIOS on recent HP laptops behaves differently with Win8 OSI,
e.g. no backlight control and no rfkill are available.  List them in
the blacklist as a workaround.

This patch tries to reduce the added items by matching "G1" suffix,
e.g. machines are named like "HP ProBook 430 G1".

Lv Zheng 8b48463f89 ACPI: Clean up inclusions of ACPI header files
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.

Len Brown 4c47cb197e ACPI: delete CONFIG_ACPI_BLACKLIST_YEAR
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.

Levente Kurusa 1bdb71af7f ACPI: Add Toshiba NB100 to Vista _OSI blacklist
This patch adds Toshiba NB100 to the Vista _OSI blacklist.

The _OSI(Windows 2006) method is bugged on the netbook resulting in
messed up PCI IRQ Routing information. This was observed on a netbook
whose SATA controller mode was set to Compatibility mode.

The controller would then issue IRQs to IRQ#16 instead of
IRQ#20, where it should have been.

No side-effects were found during testing, everything is
working as it did before.

Felipe Contreras 068aab7766 ACPI: add missing win8 OSI comment to blacklist
In my original patch[1] I wrote a comment describing the reason for
disabling Windows 2012 OSI mode for a group of machines, however, due to
unknown reasons (probably a conflict resolution mismatch), the comment
was dropped in 94fb982 (ACPI: blacklist win8 OSI for buggy laptops).

Since Matthew Garrett is making a big deal out of the lack of comments
in a separate patch[2], it might make sense to re-introduce the missing
comment so that other patch is not blocked and users don't suffer.

Felipe Contreras 94fb9823a7 ACPI: blacklist win8 OSI for buggy laptops
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.

Felipe Contreras cb7a386c6c ACPI: blacklist win8 OSI for ASUS Zenbook Prime UX31A
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).

Since v3.7, users have been forced to work around the initial
regression by modifying the boot arguments [1].

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.

Tejun Heo 3e5cd1f257 dmi: extend dmi_get_year() to dmi_get_date()
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.

ACPI: DMI Board Name: 7661W1P
ACPI: DMI BIOS Vendor: LENOVO
ACPI: DMI BIOS Date: 10/18/2007
ACPI: Please send DMI info above to linux-acpi@vger.kernel.org
ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@vger.kernel.org

2) System known to DMI, but effect of OSI(Linux) unknown:

ACPI: DMI detected: Lenovo ThinkPad T61
...
ACPI: BIOS _OSI(Linux) query ignored via DMI
ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@vger.kernel.org

3) System known to DMI, which disables _OSI(Linux):

ACPI: DMI detected: Lenovo ThinkPad T61
...
ACPI: BIOS _OSI(Linux) query ignored via DMI

4) System known to DMI, which enable _OSI(Linux):

ACPI: DMI detected: Lenovo ThinkPad T61
ACPI: Added _OSI(Linux)
...
ACPI: BIOS _OSI(Linux) query honored via DMI

cmdline overrides take precidence over the built-in
default and the DMI prescribed default.
cmdline "acpi_osi=Linux" results in:

ACPI: BIOS _OSI(Linux) query honored via cmdline

Anthony Godshall, Ampro Computers, Inc 5b27b176da ACPI: make blacklist more verbose
IMHO, ACPI disabled due to DMI failure or blacklisted year should be noted,
as is done with other ACPI blacklisting.

This will help people troubleshoot when ACPI isn't working.  Status quo is
a mysterious "ACPI Disabled" message without explanation on BIOS that
implements ACPI but not DMI.  This is actually fairly common on embedded
x86 boards.

Andi Kleen f083a329e6 [PATCH] x86_64: Clean up and tweak ACPI blacklist year code
- Move the core parser into dmi_scan.c.  It can be useful for other
   subsystems too.
 - Differentiate between field doesn't exist and field is 0 or
   unparseable.  The first case is likely an old BIOS with broken ACPI,
   the later is likely a slightly buggy BIOS where someone forget to
   edit the date.  Don't blacklist in the later case.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
