OpenCore General Discussion

At the moment it seems the scan policy isn't set in the plist. What would be an ideal value to set it to? Should it pick up my NVME drive using the default value of 

0xF0103?

All settings need to be in the plist, read documentation. You can use a value of 0 and essentially disables the scan policy.

Hi

 

So I got my system booting using OpenCore, everything is working great except for AirportBrcmFixup.kext

 

I get this error on boot: "OC: Prelink injection AirportBrcmFixup.kext - Invalid Parameter" and the kext is never loaded, all my other injected kexts works just fine.

 

I have attached my (scrubbed) config.plist, if anyone could take a look.

For DMAR we are preparing a kernel quirk, which will disable VT-d on macOS level. We believe it is a better place than DMAR dropping given that one day we should probably make APTIO VT-d support compatible with macOS. Added as DisableIoMapper in this commit.

So it is possible?

I see that some people use dravers with a prefix -64. 
These are dravers from Clover and some of them are useless, for example FSInject-64.efi and others.

Necessary dravers you can take here and here.

I've been following along with CoreBoot development for a while but was completely overwhelmed by the documentation the first time I looked into setting it up. Decided to give it a go with the beta release of Catalina. Turns out it wasn't as difficult as it looked initially and I've been able to get boot, graphics, audio and USB injection working.

 

I could still use some help resolving an nvram issue. Regardless of the EFI drivers used, I still get an AMI safe boot "F1" warning after reboot. I get the following results with various EFI driver combinations:

• AptioMemoryFix only: System boots. Does not power off on shutdown or restart
• EmuVariableRuntimeDxe only: System boots. On verbose ('-v') boot console log shows a black screen after "End RandomSeed" until Apple boot logo. Shutdown/Restart functional
• EmuVariableRuntimeDxe and AptioMemoryFix: System boots with Apple console log visible and shutdown/restart functional
• no NVRAM efi drivers: Boot hangs at "End RandomSeed"

Also a warning: VariableRuntimeDxe is not the same as EmuVariableRuntimeDxe. I compiled VariableRuntimeDxe.efi from the master branch of UDK thinking newer must be better. The module crashed on load, corrupting the motherboard memory and required shorting the motherboard CMOS pins before it would post again.

@asstastic The issue is know, but has not yet been resolved, and generally is unlikely to any time soon. Do not waste your time and hardware playing with generic-ish edk2 drivers that do not work with the AMI software stack.

Okay, so apparently the problem with AirportBrcmFixup.kext is related to Catalina.

 

Another 2 questions:

1. How can I set the default boot volume? (Using Startup Disk does not work)

2. Any way to add my Windows 10 volume? (In Clover I just chain-booted \EFI\Boot\bootx64.efi on the Windows SSD)

 @vit9696 @vandroiy2012 @Download-Fritz opencore has been described as monolithic will this be an issue in the future in terms of clover like bloat or will it remain light and clean ?

If my machine (an ASUS X299 i9 7900X) currently requires the DMAR drop to boot, will DisableIoMapper work for that?

 

I absolutely believe you, but would you mind explaining why it is better than dropping DMAR?

[Pavo]

I have no issues using VT-d enabled with macOS.

Hello

 

I'm just installed OC and everything looks ok, except some strange behavior when system wan't boot periodically with bootloader error - Couldn't allocate runtime area. 

 

Why this is happening ?

hello Andrey

 

I saw u use applesmarttouchpad kext for ur trackpad

 

I can't inject the kext in OC, can u give that lines from ur config.plist file

 

thanks

[MacPato]

I wonder if the devs could clarify something for me please @vit9696 there is a rumour circulating that OpenCore will possibly get a GUI based Menu/Style boot, is there any truth in this, because i for one prefer the minimal no frills boot. 

[vit9696]

@MacFriedIntel, if this happens, it will be optional and outside of OpenCore mainline, i.e. as an external tool/driver.

tried the new open core with the arg lapic_dont_panic=1

Kernel patcher init failure - Not Found

 

 

 

an can only boot with cpus=1

Try load the plugins followed by the kext in plist order.

Hi,

 

Looks like lapic_dont_panic=1 is kind of problematic. Don't use it for now.

As for you patch shown in the screenshot (00 74 0E 8B -> 00 EB 22 8B) - No! It bricks the kernel as I could found *a lot of* occurrences instead of just one where we want to patch.

Please grab mine instead: https://www.insanelymac.com/forum/topic/339035-pre-release-macos-catalina/?do=findComment&comment=2676207

 

 

Or at least go specify:

Base   = _lapic_interrupt

Count  = 1

 

(By the way, you can also use bitmask to match 9E and 8B as shown in my post above.)

[vit9696]

 

@errorexists, just use LapicKernelPanic = YES in Quirks.

If you use debug=x boot argument, you will also need lapic_dont_panic=1.

thank you

If quirk LapicKernelPanic should be unfortunately broken, then you could try simply using my patch (yes, as shown in your left pic) and also specify Base, Count, Identifier and MatchKernel (19.)
