There's another mysterious _DSM function under \_SB.PCI0.P0P2.UPSB.
Seems it's related to Thunderbolt technology.
Method (_DSM, 4, NotSerialized)

If (LEqual (Arg0, Buffer (0x10)
{
/* 0000 */ 0xC6, 0xB7, 0xB5, 0xA0, 0x18, 0x13, 0x1C, 0x44,
/* 0008 */ 0xB0, 0xC9, 0xFE, 0x69, 0x5E, 0xAF, 0x94, 0x9B
}))
{
Store (Package (0x02)
{
"PCI-Thunderbolt",
0x01
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
