what would things behave like if we called the dGPU IGPU instead of GFX0 ... thinking have PXS1 == GFX0 and PXS2 == IGPU
then perhaps both could leverage acceleration
then perhaps both could leverage acceleration
Got a tip for us?

MP 1,1-5,1 Activate AMD hardware acceleration

AFAIK, for those Mac that has iGPU, always use iGPU (GFX0), dGPU may be used for something else, but not HWAccel.
And for iMac Pro, due to no iGPU, then use dGPU (GFX0) for HWAccel.
No Mac can use both.

That's why I'm very curious about the implementation of hardware acceleration with MP7,1:
- Apple will use the same way to enable it as they did with iMacPro1,1?
- How MP7,1 with more than one discrete GPU will work?
- How the Radeon Duo GPUs will work?
- The implementation of the Radeon Duo will hidden this from the macOS in anyway? Seems the Duo PCB has a PCIe switch.
Thats interesting (what looks like a PCIe switch).
I'd also be curious to see what the new 16" MBP is setup like with the AMD 5000 series cards in them.
I do think that we may have to wait for 7,1 release in order to really be able to dig into how it is setup so we can clone it for multi GPU 3,1-5,1 macs.

You can download the special build of 10.15.1 for the 16” MBP already, Apple released it on SUS earlier today.
I’m inclined to think that Apple will change the way hardware acceleration is implemented for MP7,1, maybe not initially, since today’s GFX0 won’t work with multiple GPUs and probably work for just the first GPU of the Radeon Duos. It will be stupid this way for a Mac that is basically designed for video production in high scale.

Don't forget the FPGA on the Afterburner card. And there's articles all over the place claiming the T2 makes a big difference on encoding jobs.

Did you removed the Polaris GPU? Did you tested if the acceleration is really working?
I tested with a GK104 card and not even h264 works.

Unfortunately I am not in front of my PC ( i will remove the cards when I have physical access). I do all the tests remotely. The only indication for me is the NO CPU usage and no stuttering when playing the Swordsmith video.

Updating only the board id in SMBIOS. I lost GT-640, playing HEVC Video:
MFC is completely screwed (showing Macpro6,1???):

Kepler GPUs don’t have any way of HEVC hardware acceleration, NVIDIA started with Maxwell for partial acceleration. I bet that it’s using the Polaris GPU for acceleration and it’s not reporting correctly.

I was thinking about it, but here is the deal:
When the video was playing on the Titan or RX-580 I get around 40% Usage on the GPU,
But playing video on the GT-640 goes to 80% usage, so I don't think it is using the AMD. I may look at the GPU temperatures. What is a reliable software Istat?
SMBIOS it is, unsurprisingly. However, because the update is in automatic mode (generic = true), it is not just the product name that is changed; other identifiers are also changed based on an OC library. Updating the SMBIOS properties in manual mode (progressively changing iMacPro1,1 properties to MacPro5,1 ones) might offer more insight.

I already tested that. Unfortunately my setup is odd. I have an expansion chassis in the second slot and when there is nothing in the first slot no accel.

Or just no accel because the Titan doesn't support it? The only way to really know is to try with a config that just has the Titan and no other graphics card.
Well it looks like they did something.
Not exactly what we were thought we were looking for but maybe it will do what we need.

Yes, I read the patch. One thing of note, maybe this helped and disturbed at the same time, since they removed shikigva that we need too.
Maybe we will need to enable gvaForceAMDAVCDecode now.

Tested
Boot as 5,1 + GFX0 renaming + force gvaForceAMDAVCDecode = nothing
Still need to mod AppleGVA.famrework to achieve HWAccel (without HEVC encoding)
So, in this case, GFX0 renaming and force gvaForceAMDAVCDecode has no effect.

There are more parameters that can be enabled:
defaults write com.apple.AppleGVA gvaForceAMDAVCDecode -boolean yes
defaults write com.apple.AppleGVA gvaForceAMDAVCEncode -boolean yes
defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes

Ok, I'll do the renames tomorrow night, after that will be one less thing to worry forever.
Here is a copy I compiled as version 1.3.6 that contains the removed code from shikigva.
Perhaps your tests will be more conclusive than mine were.
(I'm still on 10.14.6 and a 3,1 so your results may vary)
EDIT: removed kext as the legacy options that were removed from the code werent actually something we were using nor do we want used.

Perhaps this is useless or already known info but doing a 'sample' of the VTEncoderXPCService process shows this is loaded on the iMacPro1,1 but not loaded in my MP3,1
com.apple. AMDRadeonVADriver2 (2.11.20 - 2.1.1) <15651DE0-58A0-3120-9769-0AC68E56F717> /System/Library/Extensions/AMDRadeonVADriver2.bundle/Contents/MacOS/AMDRadeonVADriver2
Open files and ports also lists this in the iMP1,1 but not in the MP3,1
/System/Library/Extensions/AMDRadeonVADriver2.bundle/Contents/MacOS/AMDRadeonVADriver2
Using 'lsof' I can also see that on the 1,1 VTEncoder is using it and on the 3,1 it is not. VideoProc and Handbrake *try* to use it but they fail.
