I executed instructions 1 to 3 of https://01.org/linux-acpi/utilities in an attempt to understand the failure msg mentioned above. The generated files from instructions 1 to 3 are attached. SSDT 2,3,4 & 6 were dissembled with reference to DSDT, e.g. $ iasl -e dsdt.dat -d ssdt2.dat, and DSDT.dat was dissembled with reference to SSDT*.dat.
My findings: 1. from acpidump.out, SB_PCI0XHC_RHUBHS11 is refer to in the 5th SSDT table. 0340: 88 55 48 53 44 0A 09 00 0A 0A 10 3C 5C 2F 05 5F .UHSD......<\/._ 0350: 53 42 5F 50 43 49 30 58 48 43 5F 52 48 55 42 48 SB_PCI0XHC_RHUBH 0360: 53 31 31 14 0C 5F 55 50 43 00 A4 47 55 50 43 01 S11.._UPC..GUPC. 0370: 14 16 5F 50 4C 44 00 A4 47 50 4C 44 83 88 55 48 .._PLD..GPLD..UH 0380: 53 44 0A 0A 00 0A 0B 10 3C 5C 2F 05 5F 53 42 5F SD......<\/._SB_ 2.From SSDT5.dat, this file contains instructions for INTEL Table ID "xh_rvp08". It seems to be instructions for all \_SB.PCI0.XHC.RHUB devices. Specifically for \_SB.PCI0.XHC.RHUB.HS11, it is to return information concerning the USB Port Capabilities _UPC and Physical Location of Device _PLD (details of these is given in http://www.acpi.info/DOWNLOADS/ACPI_5_Errata%20A.pdf) : Scope (\_SB.PCI0.XHC.RHUB.HS11) { Method (_UPC, 0, NotSerialized) // _UPC: USB Port Capabilities { Return (GUPC (One)) } Method (_PLD, 0, NotSerialized) // _PLD: Physical Location of Device { Return (GPLD (DerefOf (UHSD [0x0A]), 0x0B)) } } 3. During $ iasl -e ssdt*.dat -d dsdt.dat, the resulting file dsdt.dsl warned: * iASL Warning: There were 19 external control methods found during * disassembly, but only 10 were resolved (9 unresolved). I tried $ iasl -e ssdt*.dat facp.dat -d dsdt.dat, because facp.dat was the only other aml type file provided by acpidump, by this command created a lot ACPI ERRORs and finally resulted in "Segmentation fault (core dumped)". There is a command to cause the objects defined in HS11 to be created relative to a new location _SB.PCI0.XHC.RHUB in the namespace under certain condition. If (PCHV () == SPTH) { Scope (_SB.PCI0.XHC.RHUB) { Device (HS11) { Name (_ADR, 0x0B) // _ADR: Address } 4. "$ iasl -sa dsdt.dsl" reported 3 errors.
