 /*
- * "Ode to _OSI(Linux)"
+ * The story of _OSI(Linux)
  *
- * osi_linux -- Control response to BIOS _OSI(Linux) query.
+ * From pre-history through Linux-2.6.22,
+ * Linux responded TRUE upon a BIOS OSI(Linux) query.
  *
- * As Linux evolves, the features that it supports change.
- * So an OSI string such as "Linux" is not specific enough
- * to be useful across multiple versions of Linux.  It
- * doesn't identify any particular feature, interface,
- * or even any particular version of Linux...
+ * 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.
  *
- * Unfortunately, Linux-2.6.22 and earlier responded "yes"
- * to a BIOS _OSI(Linux) query.  When
- * a reference mobile BIOS started using it, its use
- * started to spread to many vendor platforms.
- * As it is not supportable, we need to halt that spread.
+ * 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.
  *
- * Today, most BIOS references to _OSI(Linux) are noise --
- * they have no functional effect and are just dead code
- * carried over from the reference BIOS.
- *
- * The next most common case is that _OSI(Linux) harms Linux,
- * usually by causing the BIOS to follow paths that are
- * not tested during Windows validation.
- *
- * Finally, there is a short list of platforms
- * where OSI(Linux) benefits Linux.
- *
- * In Linux-2.6.23, OSI(Linux) is first disabled by default.
- * DMI is used to disable the dmesg warning about OSI(Linux)
- * on platforms where it is known to have no effect.
- * But a dmesg warning remains for systems where
- * we do not know if OSI(Linux) is good or bad for the system.
- * DMI is also used to enable OSI(Linux) for the machines
- * that are known to need it.
+ * 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.
- * It will be ignored by default, and to get Linux to
- * not ignore it will require a kernel source update to
- * add a DMI entry, or a boot-time "acpi_osi=Linux" invocation.
+ * 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,
+ * or boot with "acpi_osi=Linux"

+ *
+ * After PCI devices are glued with ACPI devices
+ * acpi_get_physical_pci_device() can be called to identify ACPI graphics
+ * devices for which a real graphics card is plugged in
+ *
+ * Now acpi_video_get_capabilities() can be called to check which

+ * acpi_video_backlight_support();
+ *
+ * Depending on whether ACPI graphics extensions (cmp. ACPI spec Appendix B)
+ * are available, video.ko should be used to handle the device.
+ *
+ * Otherwise vendor specific drivers like thinkpad_acpi, asus_acpi,
+ * sony_acpi,... can take care about backlight brightness and display output
+ * switching.

+ * If CONFIG_ACPI_VIDEO is neither set as "compiled in" (y) nor as a module (m)
