[solved] Screen failed to wake up after screen standby

[Autines]

NullEthernet not implemented (as can be seen clearly in ioreg).
SSDT-RMNE.aml not loading, due to incorrect specification in config.plist/ACPI/SortedOrder.
It is obvious in your Clover bootlog (I extracted from ioreg):

3:573  0:000  Inserting table[2]:SSDT_RMNE.aml from EFI\CLOVER\ACPI\patched ... Not Found

Ok, I know. I rename SSDT_RMNE.aml in config.plist to SSDT-RMNE.aml. And I forgot to rename it in acpi/patch. It all OK now. You are so handsome. Thanks for all your help here. This topic should be solved.

The wake from sleep issue is solved?

Yes. I find ig-platform-id in SSDT-IGPU.aml is 0x19160002. It is different from 0x19160000 in config.plist. So I changed SSDT-IGPU.aml to 0x19160000 and it is OK now.

// Skylake/HD520
            0x1916, 0, Package()
            {
                "AAPL,ig-platform-id", Buffer() { 0x02, 0x00, 0x16, 0x19 },
                "model", Buffer() { "Intel HD Graphics 520" },
                "hda-gfx", Buffer() { "onboard-1" },
                "RM,device-id", Buffer() { 0x16, 0x19, 0x00, 0x00 },
                "AAPL,GfxYTile", Buffer() { 1, 0, 0, 0 },
            },

Yes... ig-platform-id is one of those trial/error things.
Marked solved.

Haha，thanks a lot. You may change it in your github for hd520.

Some people report 0x19160002 working better than 0x19160000.
It is not possible to predict.
I allowed for customization... The ig-platform-id is customizable in SSDT-Config (IGPI).

OK,it would be great.

You should not be dropping CPU SSDTs.
And config.plist/ACPI/SSDT/Generate (CStates/PStates) should be false.

Hi, Dear RehabMan. After I removed CStates/PStates, I found that X86PlatformPlugin and X86PlatformShim not load.
Energy Saver shows only two options in battery mode and one option in Power Adapter.

I tried HWP(SpeedShift) for Skylake.
1. HWPEnabled and Plugin type=1 in config.plist
2. Use _xcpm_idle patch made by Pike R. Alpha
3. Generate X86PlatformPluginInjector and put it in L/E.
But unless enable CStates/PStates, X86PlatformPlugin and X86PlatformShim will not be loaded.
