There are several historical + * reasons behind this policy: + * + * 1) New BIOSs tend to test only the case where the host responds TRUE to + * the latest version of Windows, which would respond to the latest/newest + * _OSI string. Not responding TRUE to the latest version of Windows will + * risk executing untested code paths throughout the DSDT and SSDTs. + * + * 2) If a new _OSI string is recognized only after a significant delay, this + * has the potential to cause problems on existing working machines because + * of the possibility that a new and different path through the ASL code + * will be executed. + * + * 3) New _OSI strings are tending to come out about once per year. A delay + * in recognizing a new string for a significant amount of time risks the + * release of another string which only compounds the initial problem. + * + *****************************************************************************/ /* * Strings supported by the _OSI predefined control method (which is * implemented internally within this module.) @@ -74,6 +99,7 @@ static struct acpi_interface_info acpi_default_supported_interfaces[] = { {"Windows 2006 SP2", NULL, 0, ACPI_OSI_WIN_VISTA_SP2}, /* Windows Vista SP2 - Added 09/2010 */ {"Windows 2009", NULL, 0, ACPI_OSI_WIN_7}, /* Windows 7 and Server 2008 R2 - Added 09/2009 */ {"Windows 2012", NULL, 0, ACPI_OSI_WIN_8}, /* Windows 8 and Server 2012 - Added 08/2012 */ + {"Windows 2013", NULL, 0, ACPI_OSI_WIN_8}, /* Windows 8.1 and Server 2012 R2 - Added 01/2014 */ /* Feature Group Strings */ diff --git a/drivers/acpi/acpica/utownerid.c b/drivers/acpi/acpica/utownerid.c index eb3aca76136..36bec57ebd2 100644 --- a/drivers/acpi/acpica/utownerid.c +++ b/drivers/acpi/acpica/utownerid.c @@ -5,7 +5,7 @@ ******************************************************************************/ /* - * Copyright (C) 2000 - 2013, Intel Corp. + * Copyright (C) 2000 - 2014, Intel Corp. * All rights reserved. * * Redistribution and use in source and binary forms, with or without diff --git a/drivers/acpi/acpica/utpredef.c b/drivers/acpi/acpica/utpredef.c index 2b1ce4cd320..db30caff130 100644 --- a/drivers/acpi/acpica/utpredef.c +++ b/drivers/acpi/acpica/utpredef.c @@ -5,7 +5,7 @@ *****************************************************************************/ /* - * Copyright (C) 2000 - 2013, Intel Corp. + * Copyright (C) 2000 - 2014, Intel Corp. * All rights reserved. * * Redistribution and use in source and binary forms, with or without diff --git a/drivers/acpi/acpica/utresrc.c b/drivers/acpi/acpica/utresrc.c index 2c2accb9e53..14cb6c0c8be 100644 --- a/drivers/acpi/acpica/utresrc.c +++ b/drivers/acpi/acpica/utresrc.c @@ -5,7 +5,7 @@ ******************************************************************************/ /* - * Copyright (C) 2000 - 2013, Intel Corp. + * Copyright (C) 2000 - 2014, Intel Corp. * All rights reserved. * * Redistribution and use in source and binary forms, with or without @@ -47,7 +47,8 @@ #define _COMPONENT ACPI_UTILITIES ACPI_MODULE_NAME("utresrc") -#if defined(ACPI_DISASSEMBLER) || defined (ACPI_DEBUGGER) + +#if defined(ACPI_DEBUG_OUTPUT) || defined (ACPI_DISASSEMBLER) || defined (ACPI_DEBUGGER) /* * Strings used to decode resource descriptors. * Used by both the disassembler and the debugger resource dump routines diff --git a/drivers/acpi/acpica/utstate.c b/drivers/acpi/acpica/utstate.c index 03c4c2febd8..1cc97a752c1 100644 --- a/drivers/acpi/acpica/utstate.c +++ b/drivers/acpi/acpica/utstate.c @@ -5,7 +5,7 @@ ******************************************************************************/ /* - * Copyright (C) 2000 - 2013, Intel Corp. + * Copyright (C) 2000 - 2014, Intel Corp. * All rights reserved. * * Redistribution and use in source and binary forms, with or without diff --git a/drivers/acpi/acpica/utstring.c b/drivers/acpi/acpica/utstring.c index 45c0eb26b33..77219336c7e 100644 --- a/drivers/acpi/acpica/utstring.c +++ b/drivers/acpi/acpica/utstring.c @@ -5,7 +5,7 @@ ******************************************************************************/ /* - * Copyright (C) 2000 - 2013, Intel Corp. + * Copyright (C) 2000 - 2014, Intel Corp. * All rights reserved. * * Redistribution and use in source and binary forms, with or without diff --git a/drivers/acpi/acpica/uttrack.c b/drivers/acpi/acpica/uttrack.c index c0027773ccc..7d0ee969d78 100644 --- a/drivers/acpi/acpica/uttrack.c +++ b/drivers/acpi/acpica/uttrack.c @@ -5,7 +5,7 @@ *****************************************************************************/ /* - * Copyright (C) 2000 - 2013, Intel Corp. + * Copyright (C) 2000 - 2014, Intel Corp. * All rights reserved. * * Redistribution and use in source and binary forms, with or without @@ -276,7 +276,8 @@ acpi_ut_free_and_track(void *allocation, } acpi_os_free(debug_block);
