It is strongly + * recommended that all ACPICA hosts mirror this policy and integrate any + * changes to this module as soon as possible. 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.) + * + * March 2009: Removed "Linux" as this host no longer wants to respond true + * for this string.
