Thanks for the acpidump.
While the DSDT does check for Linux:
Method (_INI, 0, NotSerialized)
{
If (CondRefOf (_OSI, Local0))
{
If (_OSI ("Darwin"))
{
Store (0x2710, OSYS)
}
Else
{
If (_OSI ("Linux"))
{
Store (0x03E8, OSYS)
}
Else
{
Store (0x07D1, OSYS)
}
}
}
Else
{
Store (0x07D0, OSYS)
}
Store (0x35, SMIF)
Store (0x00, TRP0)
}
OSYS isn't really used much, except to see if the HPET should be in the GUI:
Device (HPET)
{
Name (_HID, EisaId ("PNP0103"))
Name (_CID, 0x010CD041)
Name (BUF0, ResourceTemplate ()
{
IRQNoFlags ()
{0}
IRQNoFlags ()
{8}
Memory32Fixed (ReadOnly,
0xFED00000, // Address Base
0x00000400, // Address Length
_Y16)
})
Method (_STA, 0, NotSerialized)
{
If (LGreaterEqual (OSYS, 0x07D1))
{
If (HPAE)
{
Return (0x0F)
}
}
Else
{
If (HPAE)
{
Return (0x0B)
}
}
Return (0x00)
}
More significant is that if acpi_osi=Darwin,
you'll trigger a bunch of Apple hooks via "OSDW" that do who knows what...
Method (OSDW, 0, NotSerialized)
{
If (LEqual (OSYS, 0x2710))
{
Return (0x01)
}
Else
{
Return (0x00)
}
}
