(SOLVED) SSDT-INIT and SSDT-LED ACPI ERRORS #116

Open Hasodikis opened 10 months ago

Hasodikis commented 10 months ago

I would just like to ask the purpose of SSDT-INIT. I my installation on a T480s (https://github.com/Hasodikis/T480S-Hackintosh) this ssdt causes the following ACPI error:

2023-08-25 08:50:37.970023+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Error: 2023-08-25 08:50:37.970025+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Error: 2023-08-25 08:50:37.970299+0300 localhost kernel[0]: (AppleACPIPlatform) [OINI] 2023-08-25 08:50:37.970300+0300 localhost kernel[0]: (AppleACPIPlatform) [OINI] 2023-08-25 08:50:37.970436+0300 localhost kernel[0]: (AppleACPIPlatform) Namespace lookup failure, AE_ALREADY_EXISTS 2023-08-25 08:50:37.970437+0300 localhost kernel[0]: (AppleACPIPlatform) Namespace lookup failure, AE_ALREADY_EXISTS 2023-08-25 08:50:37.971440+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/dswload-462) 2023-08-25 08:50:37.971441+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/dswload-462) 2023-08-25 08:50:37.975644+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:37.975645+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:37.976443+0300 localhost kernel[0]: (AppleACPIPlatform) During name lookup/catalog 2023-08-25 08:50:37.976444+0300 localhost kernel[0]: (AppleACPIPlatform) During name lookup/catalog 2023-08-25 08:50:37.977039+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/psobject-310) 2023-08-25 08:50:37.977040+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/psobject-310) 2023-08-25 08:50:37.981311+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:37.981312+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:37.982110+0300 localhost kernel[0]: (AppleACPIPlatform) (SSDT: _INIT) while loading table 2023-08-25 08:50:37.982110+0300 localhost kernel[0]: (AppleACPIPlatform) (SSDT: _INIT) while loading table 2023-08-25 08:50:37.982908+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/tbxfload-319) 2023-08-25 08:50:37.982909+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/tbxfload-319)

This error is confusing to me, since I cannot file any dublicates. The only mention of this OINI method is in SSDT-INIT.aml.

So since I cannot correct it, I would like to ask what is it purpose. Can it be omitted (deleted) form the configuration?

OK.

PART 1: After I lot of searching, trial and error, the OINI ACPI error is no more. I changed the SSDT-INIT

FROM: DefinitionBlock ("", "SSDT", 2, "tyler", "_INIT", 0x00001000) { External (SB.PCI0, DeviceObj) External (SB.PCI0.RP09.INIT, MethodObj) // 0 Arguments External (DPTF, FieldUnitObj) External (HPTE, FieldUnitObj) External (OSDW, MethodObj) // 0 Arguments External (OSYS, FieldUnitObj) External (WNTF, FieldUnitObj) External (ZINI, MethodObj) // 0 Arguments

ZINI () If ((OSDW () && CondRefOf (_SB.PCI0.RP09.INIT))) { _SB.PCI0.RP09.INIT () } } } }

TO: DefinitionBlock ("", "SSDT", 2, "T480", "INIT", 0x00001000) { External (SB.PCI0, DeviceObj) External (DPTF, FieldUnitObj) External (HPTE, FieldUnitObj) External (OSYS, FieldUnitObj) External (WNTF, FieldUnitObj)

Method (OINI, 0, NotSerialized) { If (_OSI ("Darwin")) { Debug = "Set Variables..." HPTE = Zero OSYS = 0x07DF } } }

PART 2 There is also a second ACPI Error: 08:50:37.989058+0300 localhost kernel[0]: (AppleACPIPlatform) [_TTS] 2023-08-25 08:50:37.989194+0300 localhost kernel[0]: (AppleACPIPlatform) Namespace lookup failure, AE_ALREADY_EXISTS 2023-08-25 08:50:37.989195+0300 localhost kernel[0]: (AppleACPIPlatform) Namespace lookup failure, AE_ALREADY_EXISTS 2023-08-25 08:50:37.990198+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/dswload-462) 2023-08-25 08:50:37.990199+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/dswload-462) 2023-08-25 08:50:37.994578+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:37.994579+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:37.995376+0300 localhost kernel[0]: (AppleACPIPlatform) During name lookup/catalog 2023-08-25 08:50:37.995377+0300 localhost kernel[0]: (AppleACPIPlatform) During name lookup/catalog 2023-08-25 08:50:37.995970+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/psobject-310) 2023-08-25 08:50:37.995971+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/psobject-310) 2023-08-25 08:50:38.000396+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:38.000397+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Exception: AE_ALREADY_EXISTS, 2023-08-25 08:50:38.001196+0300 localhost kernel[0]: (AppleACPIPlatform) (SSDT: _Sleep) while loading table 2023-08-25 08:50:38.001196+0300 localhost kernel[0]: (AppleACPIPlatform) (SSDT: _Sleep) while loading table 2023-08-25 08:50:38.001994+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/tbxfload-319) 2023-08-25 08:50:38.001995+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/tbxfload-319) 2023-08-25 08:50:38.006896+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Error: 2023-08-25 08:50:38.006897+0300 localhost kernel[0]: (AppleACPIPlatform) ACPI Error: 2023-08-25 08:50:38.007171+0300 localhost kernel[0]: (AppleACPIPlatform) 2 table load failures, 32 successful 2023-08-25 08:50:38.007172+0300 localhost kernel[0]: (AppleACPIPlatform) 2 table load failures, 32 successful 2023-08-25 08:50:38.007992+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/tbxfload-342) 2023-08-25 08:50:38.007993+0300 localhost kernel[0]: (AppleACPIPlatform) (20160930/tbxfload-342)

This _TTS ACPI Error disappears only when SSDT-SLEEP is disabled in OC/ACPI.

Sleep seems to work fine without this SSDT.

Do you know what this SSDT does? Why is it necessary for this machine. The thing is every repo in github for a t480 or a t480s includes this SSDT in its configuration. I have posted issues in this but got no answers yet.
