Hi all,
thanks for yours replies.
with lilu & WEG (with argument -wegbeta & igfxframe=capri) I have this situation:
View attachment 467978
SMBIOS= macpro 6,1
set the device properties :: PciRoot(0x0)/Pci(0x2,0x0)
AAPL,ig-platform-id = 0x07006201
device-id = 0x66010000
vendor-id = 0x86800000
To enable H.264 & HEVC decoding (and encoding) on my Ivy Bridge system with RX580, I set DISABLE the HD4000 in the BIOS and set the model-id to iMacPro1,1. I use Lilu + WeG kexts.
If HD4000 is enabled, WeG kext takes care of renaming the ACPI device names (IGPU & GFX0) and setting the HD4000 platform-id to headless value (0x07006201). In this case H.264 decoding goes to H.264 but HEVC is done by the CPU (not very good).
