Try setting

 

RebuildAppleMemoryMap to False

 

SetupVirtualMap to True

 

This is what worked for me.

Unfortunately, both of those are already set. Do you have any other suggestions?

 

Thanks!

Think he meant to disable RebuildAppleMemoryMap.

i want to patch my Sandy Bridge Framebuffers and i get this in the log:

00:000 00:000 OC: Kernel patcher AppleIntelSNBGraphicsFB () init failure - Not Found

 

the SNB kexts (dosdude1 method to old HW in Catalina) are in /Library/Extensions and are in the cache. 

what does that message indicate is wrong?

Are you sure that patch is still valid? Can you find the data to replace in the binary itself?

 

EDIT: Wait don't you need the full identifier?

For those who might be interested. SSDT-SATA.aml, renames SAT0 to SATA only for OSX and leaves original names for other OSes(tested in OSX, Windows and Linux(have only couple live USB) .  You might need to edit the address, mine SAT0 is under 0x001F0002.

 

DefinitionBlock ("", "SSDT", 2, "HACK", "SATA", 0x00001000)
{
    External (_SB_.PCI0, DeviceObj)
    External (_SB_.PCI0.SAT0, DeviceObj)

    Scope (_SB.PCI0)
    {
        Scope (SAT0)

            If (_OSI ("Darwin"))
            {
                Name (_STA, Zero)  // _STA: Status
            }
        }

        Device (SATA)
        {
            Name (_ADR, 0x001F0002)  // _ADR: Address
        }
    }
}

 

 

Mind to explain when do I need this? I remember on my Clover days I have this rename patch but since I moved to OpenCore I think I don't have it already.

Thanks.

Simple answer, you don’t need this. This is better equivalent of ACPI renames (like SAT0 to SATA) via config.plist.

Does anybody know how to accelerate Arrandale Ironlake graphics on Opencore in Sierra?

I believe it's not necessary to rename SAT0 to SATA. macOS is not really checking it and does not affect functionality.

Not very well with EC and Clover. It looses LCD output on login. I can VNC to it and it is accelerated, but I cannot output to the LCD with acceleration. I think the biggest issue is that I cannot get the EDID out of it for injection

Ah, thanks for the catch!

 

With that change, I get quite a bit further, to the point shown in the included image. I believe that mpo_policy_init is from Lilu. I'm re-attaching my config.plist, as well.

 

If I move the thumb drive to a USB2.0 port, remove the R5-340X Dell GPU, and add the config for the iGPU (Skylake 530), I get to apfs_module_start. I don't have an AWAC clock, as this is Skylake, so that's not the issue. I'm assuming that these are iGPU problems. I've tried the onboard HDMI and DisplayPort ports (DisplayPort with an HDMI adapter), and the HDMI gets me the furthest:

Probably EC patch but maybe one of these others (yeah - not AWAC on skylake unless you somehow frankensteined something like a very mad man), check here, https://github.com/dortania/OpenCore-Desktop-Guide/blob/master/troubleshooting/troubleshooting.md#stuck-on-rtc-pci-configuration-begins-previous-shutdown-hpet-hid-legacy.

After login at the desktop or login for unlocking filevault? Or before the desktop login even appears? Maybe you need to adjust something in the configuration for the graphics specific to your machine like the graphics connectors.

Unfortunately, I already have the EC patch enabled (as added by TopLevel):

 

I'm going through the other fixes. Already tried the "Above 4G" boot arg, which made things worse. Trying the HPET stuff next.

 

Thanks!

Alex you actually have to edit a DSDT.dsl file after it is dissembled and abridged from its size of 483 kb to about 34kbthe rest is going to become sssdt1 ssd 2 ssdt3 and so on

I think I must be failing to understand something obvious, here. I followed the guide, and it just told me (I think) to add the SSDT-PLUG.aml and the SSDT-EC-USBX.aml, to the ACPI directory. I then did a clean snapshot, in TopLevel, to make sure that my config.plist was correct.

 

I did attempt to do my own editing, and create my own SSDT-EC-USBX.aml (rather than to use the generic Skylake one) but I got a duplicate entry on the ED device. Here's the results of my edit (attached .dsl file). I also attached the error I get (AE_ALREADY_EXISTS):

 

 

I assume that's because the existing ACPI Tables already have an entry for the H_EC?

 

Thanks!

Did you read those guides? You don't always need that for a laptop, it may already exist correctly. You just have to apply only some of the patch in that case, you have to determine this from your original table dump though.

I get about 12 of those for all kinds of reasons anyway in order to the gpu device to work correctly you have to have those changes to coincide with ssdt-gpu.aml file that has to be present in order for things to happen

@ajacocks I think smbios iMac17,1 would be better choice.

 

Edit:Did you try SSDTTime. It’s possible you only need rename for your “EC”

No I meant True / Enable.
What works for one will not always for another.

Just before login. I can't see the login screen on the LCD only through VNC. How can I adjust the connectors? If I spoof graphics the screen is connected but then acceleration does not work.

Thanks, I did indeed follow the procedures to the best of my knowledge.

 

1) This is a desktop, a Dell Optiplex 7050

2) There is no “EC” device, in the DSDT.dsl, it’s called “H_EC”

3) I did the editing to rename it, but I’m not sure that I did it correctly, as I get that duplication error that I mentioned

 

Would someone be willing to check over my edits, if I post my DSDT.dsl and my SSDT-EC-USBX.dsl, that I already linked?

 

Here’s the definition of “H_EC” from the DSDT.dsl:

 

Scope (_SB.PCI0.LPCB)
    {
        Device (H_EC)
        {
            Name (_HID, EisaId ("PNP0C09") /* Embedded Controller Device */)  // _HID: Hardware ID
            Name (_UID, One)  // _UID: Unique ID
            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                ^^^GFX0.CLID = 0x03
                Return (Zero)
            }

 

I uncommented and modified this section, in SSDT-EC-USBX.dsl:

    External (_SB_.PCI0.LPCB.H_EC, DeviceObj)
    Scope (\_SB.PCI0.LPCB.H_EC)
    {
        Method (_STA, 0, NotSerialized)  // _STA: Status
        {
            If (_OSI ("Darwin"))
            {
                Return (0)
            }
            Else
            {
                Return (0x0F)
            }
        }
    }

Does that look right?

 

Thanks!
