MooffooM Posted April 14, 2020 Share Posted April 14, 2020 Background: GPU passthru for ESXi has been broken since Mojave, I am trying to see if a combination of OpenCore and WhateverGreen can fix this. System : Dell server with E5-2600 V3 series processors, ESXi 6.7u3, unlocker 3.0, AMD RX580 video card. As a baseline I configured passthru for a windows 10 guest and it works perfectly... Step 1: Configure a Catalina 10.15.4 guest with passthru: system information lists the "display" adapter as a GPU on PCIe, correctly shows vendorID and board ID. Does not detect attached monitor and no video output. Step2: Install OpenCore, Lilu, and WhateverGreen. System boots to OpenCore boot picker, after timeout or hitting enter the system boots to Catalina. System information now shows "Radeon RX 580" GPU on PCIe, but again does not detect attached monitor and no video output. Step 3: enabled WhateverGreen debug output. See attached logs. Any help/pointers on what is going on wrong would be appreciated. Link to comment Share on other sites More sharing options...
roswellian Posted May 16, 2020 Share Posted May 16, 2020 This is interesting...I doubt it will work since the problem is macOS itself not the boot loader. By the way can you share your opencore files? Would like to try it on my esxi as well. Thanks. Link to comment Share on other sites More sharing options...
shantur Posted November 4, 2020 Share Posted November 4, 2020 @MooffooM MacOS isn't able to read the vBIOS off the GPU. You can extract the vBIOS off GPU using Windows or Linux and put it in SSDT and give it a try https://github.com/acidanthera/WhateverGreen/blob/master/Manual/Sample.dsl#L122 Link to comment Share on other sites More sharing options...
