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>

2009-09-08dmi: 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.

2009-08-28ACPI: 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>
2009-06-23ACPI: DMI to disable Vista compatibility on some Sony laptopsZhang Rui1-0/+16
Linux claims Vista compatibility to the BIOS for a number of reasons, but this brings hard lockup on some Sony laptops. Disable Vista compatibility via DMI for these laptops unless we can figure out what Vista is doing for this platform. http://bugzilla.kernel.org/show_bug.cgi?id=12904 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2008-02-03ACPI: remove redundant Acer blacklist entryLen Brown1-7/+5
dmi_check_system() does sub-string matching using strstr(), rather than exact string compares with !strcmp(). So delete the longer of the Acer blacklist entries, as its function is just a redundant console message.

2008-01-23ACPI: DMI blacklist to reduce console warnings on OSI(Linux) systems.Len Brown1-0/+343
This DMI blacklist reduces the console messages on systems which have a BIOS that invokes OSI(Linux). As the DMI blacklist already knows about these systems, the request for DMI info itself is disabled. Further, if OSI(Linux) has already been determined to have no beneift, we disable the console message requesting acpi_osi=Linux test results. Signed-off-by: Len Brown <len.brown@intel.com>

2008-01-23ACPI: make _OSI(Linux) console messages smarterLen Brown1-0/+11
If BIOS invokes _OSI(Linux), the kernel response depends on what the ACPI DMI list knows about the system, and that is reflectd in dmesg: 1) System unknown to DMI: ACPI: BIOS _OSI(Linux) query ignored ACPI: DMI System Vendor: LENOVO ACPI: DMI Product Name: 7661W1P ACPI: DMI Product Version: ThinkPad T61 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 ...

2007-03-09ACPI: make blacklist more verboseAnthony Godshall, Ampro Computers, Inc1-2/+8
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.

2006-03-25[PATCH] x86_64: Clean up and tweak ACPI blacklist year codeAndi Kleen1-21/+6
- 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.

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!
