I am on Big Sur with OC 0.6.3.
I have a MSI 8GB RX580 GPU connected via HDMI to a Samsung 4K HDR TV. The HDR works great in Big Sur. On the TV I have to enable "Input Signal Plus" to get the HDR to work.
The problem is if I turn the TV off and on, there is no signal. The only fix is to restart...
I may have done something wrong, but I cannot get the Orinoco framebuffer for my RX580. Using OC 0.6.3 on Big Sur, I install the RX580 SSDT and AGPM.kext, adding them to the config.plist but it still shows RadeonFrameBuffer.
Any help would be appreciated.
edit: FWIW, I have a MSI 8GB RX580...
I have a RX580 connected via HDMI on 4K HDR TV.
I have the problem where there is not signal after turning the monitor on and off again. All sleep is disabled. It has been suggested that forcing the frame buffer Orinoco will fix this. But I cannot find instructions for this. I am on opencore...
Every share option fails when trying to export from FCPX. I guess it is trying to use quick sync or my dGPU because there is virtually no cpu activity. Unfortunately there is no GPU activity either.
From what I can tell there is no way to force FCPX to use CPU for rendering.
There is an option...
I had hopes that it was working, but it just went to black screen after 36 hours or so.
I am now trying "headless mode" though I do not really understand the implications or difference.
I have changed my device properties to just be:
Ah, just spent a chunk of time banging my head. ha. yeah, it wouldn't boot :)
I took the pciroot from your config and put it in my working config.plist attached. Will see how we go.
If you think it is possible to make an ASRock EFI, that'd be great. Cheers!
Looking for some assistance. I switched from iMacPro1,1 to iMac19,1 in order to use sidecar. Since there I have issues with random black screen that can't be woken from. Sleep is disabled.
I have tried patching frame buffer in different ways, with the same result. Can someone look at my config...
I switched from iMacPro1,1 to iMac19,1 in order to use sidecar. Since then I have this issue where the screen goes black and cannot be revived. SSH and SMB work, but I cannot VNC (share screen).
This seems to be a framebuffer issue, so I patched the config.plist. But the issue still occurs.
Yes, I made a typo. It is ASRock Z390M-itx/ac.
Thanks for the tip about framebuffer. I have inserted that pciroot.
I don't exactly know how to reproduce the problem before as I found this morning it would wake normally from blank screen.
Any suggestions to test framebuffer?
