I'm still struggling getting RX580 working with Vega as IGPU for an X99 platform on High Sierra. I tried injecting different FB through the clover startup menu, specifically for the RX580 without any luck. Is there anything needed on the clover config for IGPU on x99? As I'm troubleshooting, I was thinking about PCI-E assignment for MacOS.
On my standard setup, I have the main GPU on the 16/X8_1 slot, and the secondary (RX580) on the 16/X8_3 slot. On this configuration it boots to black screen. No changes even if apply different FB names (Guariba, Orinoco, Dayman). When I look at the IOREG output, the VEGA card is on slot BR3A@3
When I swap cards and install the main GPU on the 16/X8_3 slot, and the secondary (RX580) on the 16/X8_1 slot. I get reboots @ gioscreenlockstate. No changes even if apply different FB names (Guariba, Orinoco, Dayman). When I look at the IOREG output, the VEGA card is on slot BR2A@2
I figured that because the OS sees 16/X8_3 slot as BR2A@2, maybe the VEGA needs to be in this slot? How can I get it to stop rebooting?
