tests/acpi: update expected DSDT blob for aarch64 and microvm
After PCI link devices are moved out of the scope of PCI root complex, the DSDT files of machines which use GPEX, will change. So, update the expected AML files with these changes for these machines.
Mainly, there are 2 changes.
1) Since the link devices are created now directly under _SB for all PCI root bridges in the system, they should have unique names. So, instead of GSIx, named those devices as LXXY where L means link, XX will have PCI bus number and Y will have the INTx number (ex: L000 or L001). The _PRT entries will also be updated to reflect this name change.
2) PCI link devices are moved from the scope of each PCI root bridge to directly under _SB.
Below is the sample iASL difference for one such link device.
Scope (\_SB) { Name (_HID, "LNRO0005") // _HID: Hardware ID Name (_UID, 0x1F) // _UID: Unique ID Name (_CCA, One) // _CCA: Cache Coherency Attribute Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings { Memory32Fixed (ReadWrite, 0x0A003E00, // Address Base 0x00000200, // Address Length ) Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, ) { 0x0000004F, } })
+ Device (L000) + { + Name (_HID, "PNP0C0F" /* PCI Interrupt Link Device */) + Name (_UID, Zero) // _UID: Unique ID + Name (_PRS, ResourceTemplate () + { + Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, ) + { + 0x00000023, + } + }) + Name (_CRS, ResourceTemplate () + { + Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, ) + { + 0x00000023, + } + }) + Method (_SRS, 1, NotSerialized) // _SRS: Set Resource Settings + { + } + } + Device (PCI0) { Name (_HID, "PNP0A08" /* PCI Express Bus */) // _HID: Hardware ID Name (_CID, "PNP0A03" /* PCI Bus */) // _CID: Compatible ID Name (_SEG, Zero) // _SEG: PCI Segment Name (_BBN, Zero) // _BBN: BIOS Bus Number Name (_UID, Zero) // _UID: Unique ID Name (_STR, Unicode ("PCIe 0 Device")) // _STR: Description String Name (_CCA, One) // _CCA: Cache Coherency Attribute Name (_PRT, Package (0x80) // _PRT: PCI Routing Table {
Package (0x04) { 0xFFFF, Zero, - GSI0, + L000, Zero },
.....
})
Device (GSI0) { Name (_HID, "PNP0C0F" /* PCI Interrupt Link Device */) Name (_UID, Zero) // _UID: Unique ID Name (_PRS, ResourceTemplate () { Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, ) { 0x00000023, } }) Name (_CRS, ResourceTemplate () { Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, ) { 0x00000023, } }) Method (_SRS, 1, NotSerialized) // _SRS: Set Resource Settings { } } } }
