Just a side note, my weird WEG setup is still working, even on the new safari, no error with netflix and other streaming platforms #post-2109696, If it can help someone
My DRM is not working on Big Sur with a test machine with an RX570.
Real3x, could you give us more details of your setup, like if you are testing with Big Sur?
Also, I notice some details with Big Sur using Lilu and WhateverGreen in IORegistryExplorer,
and I was hoping you could check yours.
In IORegistryExplorer, under IOService:Root/iMacPro1,1 one of the Properties listed may be
a "hwdrm-id" and/or a "shiki-id." With my working system using Ivy Bridge and an RX560 on
Catalina, I use a boot argument shikigva=144 and I see a hwdrm-id with the same value
as the board-id, namely the iMacPro1,1's "Mac-7BA5B2D9E42DDD94". I don't need to enter
a shiki-id or agdpmod on my working Catalina system with shikigva=144, and both ATV and
Quicktime work on DRM media. Does yours end up as a "shiki-id" value there?
On my system where DRM is not working on Big Sur with a RX570 and iMacPro1,1, I have
tried various combinations including yours and nothing works.
I notice that if I look at the RX560 GFX0 accelerator at
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG0@1/IOPP/GFX0@0/AMDRadeonX4000_AMDBaffinGraphicsAccelerator
in my RX560 machine, one of the Properties is IOGVACodec with a value of AMDU6V3.
If I look at the RX570 GFX0 accelerator at
IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG0@1/IOPP/GFX0@0/AMDRadeonX4000_AMDEllesmereGraphicsAccelerator
the IOGVACodec Property still has a value of AMDU6V3. I thought the correct value for
Ellesmere RX570 or RX580 was AMDU7V4. Could you check yours and see what IOGVACodec
property value you have for the RX580?
Thanks.
