Can anyone confirm that vsmcgen=1 not needed?

 

Apparently download the latest commit of OC, Lilu, WEG & ALC but Catalina was able to boot w/o vsmcgen=1, however, BS Beta3 cannot boot w/o vsmcgen=1.

 

Anyone able to assists?

 

vsmcgen=1 is needed for me to boot Big Sur beta 3. I don't care whatever other ppl are saying, different systems can behave very differently. What's even more weird is that for me, I can boot with -v and without vsmcgen=1. If I took out that verbose flag -v, then it will stuck at Apple Logo.

Hi everyone
I present a problem that I continue to have with BIG SUR even with the beta 3 that the ALC892 sound card of my motherboard in Asus Z87 plus in signature with OpenCore.
Despite all attempts made even with the help of the friend Cyberdevs does not want to know.
It works all the kexts are loaded but the audio is not enabled
With the clover I have never had problems of this kind I have the audio perfectly working.
I am convinced that it is an OpenCore problem that somehow blocks the audio on my motherboard.
I move some pictures so you notice the difference between the clover with catalina and opencore with big sur.
I have finished all the options and ideas to do, if someone can politely indicate a definitive solution to solve this problem.
Alternatively I will have to wait for a Clover Bootloader version that works with Big Sur to come out to have the audio activated.

New issue for me.

I have -wegnoegpu and  in my config.plist but in about this mac i still have  and this is what i think is causing my black screen after sleep.

This does not happen in Catalina and in Catalina all i need is the device property of disable-external-gpu.

Anyone else with dual graphics see the same?

device --> properties

PciRoot (put the pci path of the card you want to make disappear)

example:

 

PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x8,0x0)/Pci(0x0,0x0)

IOName    | string | Display

class-code | data   | FFFFFFFF

 

 thanks to my guide and master  Gengik84
in my Z97 hack it worked to make the nvidia disappear on catalina

My current config disables nvidia card in Catalina though. So the PciRoot should be correct unless it changes in Big Sur? As for the data FFFFFFFF I’m not sure how to put that in with plist editor as at the moment I use 01000000.

just info rolling back AppleAHCIport.kext from Catalina to BigSUr 3 to get get right controller (Intel 8 series/Haswell)

@SavageAUS you have to insert them as I put them

[chris1111]

IF Beta4 showing Preboot I will make a package dedicated only to this patch which will not install any files and which will correct it by restarting. The name will show me the Disk

@TrickyHunter not sure if you have an all DP setup; if you do, try putting one monitor in the HDMI port. Back in Catalina, I had an issue with my 5700XT card that wasn’t initializing any DP output if a HDMI screen wasn’t connected. I blamed the drivers but I never found a true solution and just lived that way, since the remaining screens were usable afterwards.

 

Using a HDMI screen also helps me stop the stupid flickering screen in Windows AMD wasn’t able to fix yet - the DP screens flick every now and then; the HDMI output stays on all day and night long.

 

Other than that, then I’m out of suggestions.

Hi @ludox

On OpenCore, the layout-id is 7. On Clover-Catalina, the layout-id is 5. Have you test to use the same settings (5)? Just my opinion.

there is no tutorial
attach config with PCI path of the card you want to make disappear

[Partime]

Not sure if this is the right place, so please forgive.....

 

As I go through testing with OC and Beta3, I have a USB-C Jabra Blue Tooth adapter that is not working.

The same USB-C port has not problem powering and working with an external SSD.

 

Not sure how to go about figuring this problem. Would greatly appreciate any suggestions.

 

thanks.

This is the path of my nvidia device.

PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)

Thanks for trying mate. Unfortunately yes I do have one HDMI and two DP all connected to the AMD 5700 XT. It's weird that I have only seen one or two other ppl having the same issue as mine given that 9700K and 5700XT is a very common combination. And I swear that I followed the open core guide very carefully with only minimal changes needed.

 

The thing is it's extremely hard to debug in this case because even if I use -v, the black screen happens after all the verbose information prints out. So nothing related to the black screen itself is printed. I might have to search for a macOS console log or something to figure out exactly why.

Thanks for that. I added it to my config and now the nvidia card is gone.

@OneLife2000 It's broke for all of us, use Xcode instead, remember to make a back up before editing.

I may have missed it in one of your posts, but have you tried disabling WEG?

 

There are issues with 5700XT and WEG in Catalina (that may also occur in BigSur); disabling WEG helped (but I believe these were issues once macOS was booted). There were, as I recall (from another forum), some subsequent issues with this approach affecting one of ports on the 5700XT when WEG was disabled.

Yeah, I tried that a few times without luck. I can tell that at least HDMI monitor has indeed signal but it's just pure black. So it might not be same issue as others normally would have (where the monitors lose signals entirely). 

 

I also had a look at the system.log file under /var/log folder and couldn't really see anything suspicious.
