^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 164) * The story of _OSI(Linux)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 165) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 166) * From pre-history through Linux-2.6.22, Linux responded TRUE upon a BIOS
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 167) * OSI(Linux) query.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 168) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 169) * Unfortunately, reference BIOS writers got wind of this and put
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 170) * OSI(Linux) in their example code, quickly exposing this string as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 171) * ill-conceived and opening the door to an un-bounded number of BIOS
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 172) * incompatibilities.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 173) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 174) * For example, OSI(Linux) was used on resume to re-POST a video card on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 175) * one system, because Linux at that time could not do a speedy restore in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 176) * its native driver. But then upon gaining quick native restore
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 177) * capability, Linux has no way to tell the BIOS to skip the time-consuming
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 178) * POST -- putting Linux at a permanent performance disadvantage. On
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 179) * another system, the BIOS writer used OSI(Linux) to infer native OS
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 180) * support for IPMI! On other systems, OSI(Linux) simply got in the way of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 181) * Linux claiming to be compatible with other operating systems, exposing
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 182) * BIOS issues such as skipped device initialization.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 183) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 184) * So "Linux" turned out to be a really poor chose of OSI string, and from
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 185) * Linux-2.6.23 onward we respond FALSE.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 186) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 187) * BIOS writers should NOT query _OSI(Linux) on future systems. Linux will
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 188) * complain on the console when it sees it, and return FALSE. To get Linux
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 189) * to return TRUE for your system will require a kernel source update to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 190) * add a DMI entry, or boot with "acpi_osi=Linux"
