hw/cxl: Add QTG _DSM support for ACPI0017 device
Add a simple _DSM call support for the ACPI0017 device to return fake QTG
ID values of 0 and 1 in all cases. This for _DSM plumbing testing from the OS.
Following edited for readability
Device (CXLM)
{
Name (_HID, "ACPI0017") // _HID: Hardware ID
...
Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method
{
If ((Arg0 == ToUUID ("f365f9a6-a7de-4071-a66a-b40c0b4f8e52")))
{
If ((Arg2 == Zero))
{
Return (Buffer (One) { 0x01 })
}
If ((Arg2 == One))
{
Return (Package (0x02)
{
One,
Package (0x02)
{
Zero,
One
}
})
}
}
}
