ACPI / osi: Collect _OSI handling into one single file
_OSI handling code grows giant and it's time to move them into one file.
This patch collects all _OSI handling code into one single file.
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.
CONFIG_DMI is not useful as stub dmi_check_system() can make everything
stub because of strip.
No functional changes.

* The story of _OSI(Linux)
|
||||
*
|
||||
* From pre-history through Linux-2.6.22, Linux responded TRUE upon a BIOS
|
||||
* OSI(Linux) query.
|
||||
*
|
||||
* Unfortunately, reference BIOS writers got wind of this and put
|
||||
* OSI(Linux) in their example code, quickly exposing this string as
|
||||
* ill-conceived and opening the door to an un-bounded number of BIOS
|
||||
* incompatibilities.
|
||||
*
|
||||
* For example, OSI(Linux) was used on resume to re-POST a video card on
|
||||
* one system, because Linux at that time could not do a speedy restore in
|
||||
* its native driver. But then upon gaining quick native restore
|
||||
* capability, Linux has no way to tell the BIOS to skip the time-consuming
|
||||
* POST -- putting Linux at a permanent performance disadvantage. On
|
||||
* another system, the BIOS writer used OSI(Linux) to infer native OS
|
||||
* support for IPMI! On other systems, OSI(Linux) simply got in the way of
|
||||
* Linux claiming to be compatible with other operating systems, exposing
|
||||
* BIOS issues such as skipped device initialization.
|
||||

|

*
|

* From pre-history through Linux-2.6.22,

* Linux responded TRUE upon a BIOS OSI(Linux) query.
|
||||
*
|
||||
* Unfortunately, reference BIOS writers got wind of this
|
||||
* and put OSI(Linux) in their example code, quickly exposing
|
||||
* this string as ill-conceived and opening the door to
|
||||
* an un-bounded number of BIOS incompatibilities.
|
||||
*
|
||||
* For example, OSI(Linux) was used on resume to re-POST a
|
||||
* video card on one system, because Linux at that time
|
||||
* could not do a speedy restore in its native driver.
|
||||
* But then upon gaining quick native restore capability,
|
||||
* Linux has no way to tell the BIOS to skip the time-consuming
|
||||
* POST -- putting Linux at a permanent performance disadvantage.
|
||||
* On another system, the BIOS writer used OSI(Linux)
|
||||
* to infer native OS support for IPMI! On other systems,
|
||||
* OSI(Linux) simply got in the way of Linux claiming to
|
||||
* be compatible with other operating systems, exposing
|
||||
* BIOS issues such as skipped device initialization.
|
||||
*
|
||||
* So "Linux" turned out to be a really poor chose of
|
||||
* OSI string, and from Linux-2.6.23 onward we respond FALSE.
|
||||
*
|
||||
* BIOS writers should NOT query _OSI(Linux) on future systems.
|
||||
* Linux will complain on the console when it sees it, and return FALSE.
|
||||
* To get Linux to return TRUE for your system will require
|

* a kernel source update to add a DMI entry,
