Wow!!!! That the reason why I have mouse lag!!!!

How I can find this byte?
I will patch it to zero and the only problem will be brightness control to solve!!!
 
Try using Whatevergreen debug version and use flag -wegdbg to find out how the OS is recognizing your connectors, then you can insert a framebuffer if whatevergreen's version doesn't work, and use that info to patch.

For example this is what I did for Palena FB.
View attachment 516081

The con @ DBG info is the debug info from Whatevergreen, and the last line is the patch I inserted on my config.
It worked but as I explained in another thread, the problem with Palena is stability, after wake from sleep, I could get a screen freeze, and using the default, but only injecting the Palena parameters, I get 100% stability.

Edit: I kept the Palena connector 1 flags as they seem to be related to HDCP on the internal screen.

Also you may need Whatevergreen for other DRM and AGDP patches, so in my experience there's no real need to manually inject a FB.

You can also force Connector Info on Whatevergeen's FB using an SSDT




This is what i recieve

As for the HDCP flag, it may be hardcoded into the Palena FB, but the flag is this (green):

Screen Shot 2021-04-23 at 7.33.06 PM.png


As you can see I'm not changing the flag to 0901 (0109 reversed) as Whatevergreen detects, because I loose HDCP, but if I keep the original 3905, I also keep the 08 (green) while I zeroed all others after the (priority I think?) byte as it is suggested by the AMD FB patching guide. then it's good.

Remove all injection flags from your config, don't inject any framebuffers, let Whatevergreen do it and see if you then need to adjust that.

Smells like we close to the final step of success :)
But your gpu are DisplayPort based

I believe TB3 video out is fed by DP internally, same as miniDP port. but both signals can be plugged/passively converted to HDMI.
The connector type may not be as important as the signal type.

What do you mean?

Zbook g3,4,5 are DisplayPort based with converters to VGA, HDMI. One of DP is connected to thunderbolt controller and working in daisy chain mode.

Igpu and mxm vga lanes are simply connected to mux chips. So the ports switch is simply made by gpu power off or idle.

That's what I meant, and that signal-wise you can plug into hdmi or DVI monitor through passive converter and it will work.

I assume the EC takes care of switching the outputs somehow, but not exactly sure as they keep making the SSDT's more convoluted and harder to trace functions.

During one of my attempts to use Catalina, I tried to turn off the DGPU in many different ways (SSDT's) and found there's no way to do it, other than switching to IGPU mode in the bios directly.
All other tries resulted in hard reboots.

After all my tests. I had this bug that after waking from sleep, the DGPU outputs stayed off (even in Windows), and a EC reset fixed it.

Internally the signal goes DGPU->MUX->Output/LCD Display, so I'm guessing that in some part of this chain something could be causing my problem with Catalina. The SSDT that defines possible displays from IGPU or DGPU is very unique and again convoluted and this could be causing some missing bit that makes Catalina boot stall.
Even from Linux I'm getting:
[Firmware Bug]: ACPI(PEGP) defines _DOD but not _DOS

But Linux finds a way around it, (I guess ignores it) and so does Mojave, but maybe Catalina doesn't?

My next attempt will be to patch Catalina as if it were an unsupported older Mac to see if I can get closer to figuring this problem.
(My #1 suspect is skylight framework)

No success... display edp is just blinking with signal loss and image for second and then goes black.

If I use native os framebuffer without any patch or amd inject, the display lid working. But if I close lid, using the hdmi or vga or dp, the mouse lag appears. If I use magnet to act with holl sensor of lid which is located under power button, the display edp is hotplug comes to disconnect the lag appears. So I done next thing: patch berbice, Palena, baladi and other framebuffer with same connector info to zeros except vga port . So in practice, if os is using one of this, all other ports will be off. Patch with hex code find and replace. But nothing is happening. But patch will happen only if I inject framebuffer name with clover.

I don’t understand where os or how is selecting framebuffer? Even if I delete Whatevergreen kext, it will load same framebuffer with lags of close lid :(
