Issue with WEG 1.5.2

[Eniac60]

I have a problems whit Whatevergreen version 1.5.2 .

With this version i don't have hardware acceleration though the GPU is recognized exactly , on OC 0.7.0 - 0.7.1 and 0.7.2

My graphics card is R9 270X 2gb

With whatevergreen versione 1.5.1 it's work fine.

• Is your GPU natively supported?
• Do you inject device-id?
• Do you use FakePCIID or any similar stuff?

[Eniac60]

-I don't think this card is natively supported

• Yes device-id is injected on Device-Properties

• i don't use FakePCIID or similar stuff

[vit9696]

Does it work without injecting this device-id?

[Eniac60]

No, without injecting device-id doesn't work

[vit9696]

Update to master and inject no-gfx-spoof = <01 00 00 00> (any value really).

[Eniac60]

I updated to version 1.5.3 as you suggested and added the line in device properties but on reboot it crashes after the first phase.
My card is not an X (in the first post I wrote wrong saying 270X) it has device-id 6811 so I inject the fake-id of the X (device-id 6810) which is native, and up to version 1.5.1 it has always worked perfectly.

[vit9696]

Crashes how? This is not helpful without a symbolicated kernel panic. Just to clarify, with this property injected 1.5.3 is not different from 1.5.1.

[Eniac60]

The screen goes completely black and I can't photograph the verbose where it stops. How can I help you ?

[vit9696]

Hrm. Can you confirm that 31b8dd1 is broken for you and c8c0711 works fine?

See: https://dortania.github.io/builds/?product=WhateverGreen&viewall=true

[Eniac60]

No, up to version 1.5.1 it works perfectly with all other versions 1.5.2 and 1.5.3 not work . In the photo you can see exactly the versions it works well with

[vit9696]

In this case I close this is as user error, since c8c0711 changes nothing but a version number.

[Eniac60]

I humbly apologize, I was using a key with still inserted "no-gfx-spoof = <01 00 00 00>" now I have cleaned everything and I have tried again, with the version c8c0711 works fine.
With all other higher versions, up to 1.5.3 it always starts, the graphics card is recognized correctly but without acceleration.
I got confused, forgive me

[vit9696]

May I see your IOReg?

there he is..

Check master. Make sure you update to a9741df and include no-gfx-spoof property. Provide ioreg.

I has issue on WEG 1.5.2 too but the situation is slightly different

To what i understand, the spoofing is by SSDT
https://github.com/osy/HaC-Mini/blob/master/ACPI/SSDT-GpuSpoof.asl

and the graphic render glitch is patch via
https://github.com/osy/Polaris22Fixup

on WEG 1.5.1 it work well, but once run on WEG 1.5.2
i had this issue

osy/HaC-Mini#614

Wonder do i need to inject device-id via device property ? since it's already spoof via SSDT

PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)
- device-id  : <DF670000>

[Eniac60]

Bingo , now work fine with versione 1.5.3 (a9741df) .
If you find it useful I am attaching the ioreg versions with and without no-gfx-spoof
Without no-gfx-spoof.zip
with no-gfx-spoof.zip

nice! This can also be done via SSDT https://github.com/carlox97/Getting-Started-With-ACPI/commit/2aa3f875db6f8104def3f8e5b7886671d294505f

Here is one sample

[PracticalPear413]

Please help, this is not working for me. I added no-gfx-spoof as 01000000 and deviceid as DF670000 in config.plist, with WhateverGreen 1.5.5 I'm stuck on black screen.
Using 1.5.1 results in the same problem :(

I think I have a similar problem as well. I have a R9 380 that I've used for two previous builds without problems. If using without spoof, system crashes basically in any site with a more demanding animation (simple animations really), I can only load static websites.

When with SPOOF to the (supported) 380x, the crashes stop, but no hardware acceleration at all, sluggish performance. Tried a couple of older versions and nothing. I don't have any DeviceProperties associated with the card (with the specific codes above), any references I could consult to help troubleshoot this?

Thanks!

FUP: Tried adding the no-gfx-spoof, I get the hardware acceleration, but still crashing.
By crashing I mean that it crashes at any sign of "heavy" graphics on websites.

I found a thread here that mentioned the possibility of the GPU locking up, and it is pretty similar to my case. I can see the "DumpGPURestart" a couple of minutes before the system watchdog throws the error: "no successful checkins from WindowServer in 120 seconds".

Lilu 1.5.8
WhateverGreen 1.5.5 (tried a couple of other versions as well)

Hello, I'm also encountering a similar issue with WEG builds where both the device-id (for spoofing purposes) and no-gfx-spoof properties were added. I would assume that the causation of the KPs/crashes is similar to that which @lowercase00 has described above.

Here's a KP log from 2 weeks ago (Apr 30th):
kp_30.apr.2022.txt

The way this issue presents itself is that the system stops responding, and shortly after, it completely restarts on it's own – all the way to POST, I mean.

I do not encounter this issue if I use WEG v1.5.0 and use an SSDT-GPU-SPOOF patch, or just use my iGPU with the dGPU disabled.
