Tracing back the AMD GPU wakeup issue to its origin

Thanks a lot. Now system setting display AMD RX 580 8GB. But power draw hasn´t changed.

 

Complete system idle:

88 watt with a NVIDIA 1060 = approx. 8 watt for the GPU

116 watt with RX 580 = approx. 36 watt (!) for the GPU

 

For graphics power management to work properly make sure you have selected a system definition which matches your hardware, checked that the GPUs have proper names in your DSDT and checked that platform power management (ASPM) in BIOS setup is enabled.

Hi Mieze,

 

thanks for your answer. Just I don´t know what exactly to do.

 

My system runs as Mac Pro 6.1 with perfect speedsteps.

I use the kext patch "Rename AMD R9 xxx to AMD RX 580", in system infomation the GPU appears as RX580

I switched ASPM in BIOS, but there is no "enabled" settings, just Auto or "L1", whatever that means. This brought down power consumption from 116 watt to 113 watt idle - not bad.

 

So what is the easiest way to make shure the GPU has a proper name in DSDT? I don´t use a DSDT file, just some SSDT, Pikes speedsteps, audio and nvme patch.

Do I need a DSDT file or is there a way in clover?

The MacPro6,1 has two GPUs which have the names GFX1 and GFX2. Take a look at IORegistry in order to find out which names your GPUs are using. Basically you can patch your DSDT manually or try to use Clover's ability to apply custom DSDT patches (which might not be possible in some cases).

 

By the way, are you injecting a framebuffer personality? I'm asking because some of these also influence graphics power management by selecting special configuration parameters for the GPU.

 

Mieze

Hi Mieze,

 

thanks for your efforts - but I already fail to find out whether it is GFX1 or GFX 2. No GFX ist to be found in IORegistryExplorer.

 

The other thing: I use RedeonDeinit, which is kind of black box. How to patch GFX number or/and framebuffer exactly, and does this work together with RadeonDeinit or do I have to use a different approach?

 

Specialists like you can´t surely imagine the absolute basics problems a dummy like me has. I poke around until the system runs sufficient, and then I´m going to use the system for work for 2 years without changing something.

GFX isn't showing up in IOReg because you probably aren't renaming your PEGx to GFX in your SSDT or DSDT.

The MacPro6,1 has two GPUs which have the names GFX1 and GFX2. 

Outstanding work.  Suggestion, edit Post #1 dsdt patch to Device (GFX0) replacing Device (PEGP).

Can someone explain to me why SSDT patching doesn't work unless you inject ATI using Clover?

Basically it boils down to the question: why do Apple's framebuffer drivers define dedicated framebuffer personalities although they are able to auto-generate a default personality for almost any graphics card we are using?

 

Well, I think that the answer is quite obvious. It's because the auto-generated connector data isn't meant to be a full replacement for a dedicated one but more as a fallback mechanism for situations in which a dedicated framebuffer personality for a certain graphics card is missing so that basic screen output can be provided even for unknown hardware. This is also the reason why auto-generated connector data is limited in functionality in a way that it doesn't support advanced feature like multi screen support, etc.

But I get multi-monitor perfectly fine with auto-generated connector data when I don't inject anything, still doesn't explain why SSDT/DSDT injection will only work when ATI injection is enabled only.

Apple's algorithm for auto-generation of the connector data is defective. In case multi screen support is working for you, you might be one of the lucky few but this doesn't mean the the connector data is 100% correct. The hotplug id might be wrong causing display detection to fail after wakeup. There are several reports of limited functionality using the default framebuffer so that we must consider that as the normal state.

 

I only wonder if this is a driver bug or if Apple designed it that way intentionally?

OK I can understand that, maybe I should re-phase the question then. What all info is needed in the SSDT/DSDT injected in order to not have to use Clover's ATI Inject enabled?

Sir Ive Injected AGPM For my AMD Radeon HD 7650M via FakeSMC.

 

Sir I've used MBP 9,2 Board id for CPU and MBP 8,3 board id for  GPU PM, sir is it good way for getting PM !

 

Sir I've tried everything to get  AMD Radeon HD 7650M on 10.13.1 but no luck :(

sir can u guide me!

 

Want for u reply !

Did you make  it as Device Properties injection or also DSDT Fix? Second place can explain why SSDT injection has or not has effect.

 

But I see something strange. If I set RadeonDeInit and inject Arbitrary properties then drivers ignore these properties, i.e. I can't inject model name.

It is very strange because I see the properties present in DeviceTree/Platform.

May be boot.efi thinks that the card is absent?

There are number of cards where connector data in video bios does not correlate with hardware. IMHO, apple software just fails there as result.

I think I injected as Device Properties, take a look.

External (_SB_.PCI0.GFX0.PEGP, DeviceObj)

Should be 

External (_SB_.PCI0.PEG0.PEGP, DeviceObj)

or 

 External (_SB_.PCI0.PEG0.GFX0, DeviceObj)

You either use PEGP or GFX0 not both, if you are replacing PEGP with GFX0 in ACPI patching you don't want _SB_.PCI0.PEG0.GFX0 also in SSDT

used MBP 9,2 Board id for CPU and MBP 8,3 board id for  GPU PM, sir is it good way for getting PM !

Not correct, MPB 8,3/HD 6xxxM, enables threshold GPM

Try MPB 11,5/R9 3xxM, enables pstate GPM

 

AMD HD 7xxx and newer use same APGM/.../GFX0 properties (ex, GFX1)

Edit: Except HD 7650M, actually 6xxx; credit: Slice/#249

Thanks for looking at this for me... I tried both approaches and in both cases black screen at boot.

 

Could I be missing something fundamental that is causing RadeonDeInit and even the SSDT method both fail? Like I said, WhateverGreen does work.

Hi, can you please look at my attached ioreg screenshots and tell me if I set my radeon r9 290x GPU PM correctly. AGPM shows under ATY,AMD,RadeonFramebuffer@0 but my display is registered under ATY,AMD,RadeonFramebuffer@3. I have disabled IGPU in BIOS, set ASPM for PEG only and didn't use framebuffer injection or patching since i'm using only one LCD. Sorry if this is too much OT and thanks to all the developers for their priceless work

Yes AGPM will show up under the first ATY
