AMD Radeon Performance Enhanced SSDT

[Maf3r0]

is there SSDT for RX590?

working in progress, as @mattystonnie said

Just got my hands on a RX 480 8GB , now I will work on Polaris.

Report on my RX580, no much difference so far with or without the SSDT.
After sleep/wake, the score of open cl jumps from 30036 to 42965.
In Windows 10, the score is between 42822 to 44633 usually.

stock values are too lower

maybe there's something wrong

take a look at my stock values:

A little better Metal score compared with the last one #340

For advanced user, copy into clover device properties, change "PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)" with your GPU path.

Edit. Luxmark score bigger with 900 points.

The SSDT is not injected try to check addDTGP like in the picture.

Do I have to use your SSDT with WEG? It seems my Vega56 cannot run correctly without WEG. No 3D acceleration and Geenbench only scored 5463.

Tested SSDT-RX580- Version 1.0

Catalina 10.15.4 (iMac17,1 6700k rx 580)

Before:
OpenCL: 44354
Metal: 51257

After:
OpenCL: 44633
Metal: 53981

So it did something, Thanks Mattystonnie!

My build is pretty similar to yours, but my Metal result is only 50700. @mattystonnie, what should we expect to see in IOReg with this SSDT patch?

I attached mine below for reference. Note: I'm using SSDT-RX580-M.aml with WhateverGreen + agdpmod=pikera argument and nothing else.

Can you please tell me how to addDTGP in Opencore? Thank you.

Also, I have added the device properties from post #355. No change in score.

Ioreg copy with device properties added.

For advanced user, copy into clover device properties, change "PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)" with your GPU path.

With clover device properties:
Metal: 51805
Metal: 51362 (after sleep/wake)
OpenCL: 45584
OpenCL: 45669 (after sleep/wake)

By adding the clover device properties, I removed the SSDT. Is this correct, or do I have to leave the SSDT?
