i tested on H3 (no difference there too mali 400) the problem is the same.
when using modesettings, the interface slows down more than with fbturbo over also check armsoc.

Okay, I will try that next. Here is what I just found out after a few days of testing:

Your image with the legacy kernel does not boot past u-boot for some reason. Just black screen. I will try again to see if there is anything happening past u-boot on disk.

So, I built a fresh image with the next-kernel. This one boots fine, and when I make it to Xfce, I am getting a new error in Xorg.0.log (the previous error is now gone):

Code:
[   127.083] (II) AIGLX: Screen 0 is not DRI2 capable
[   127.083] (EE) AIGLX error: dlopen of /usr/lib64/xorg/modules/dri/swrast_dri.so failed (libLLVMCoroutines.so.10: cannot open shared object file: No such file or directory)
[   127.083] (EE) AIGLX error: unable to load driver swrast
[   127.083] (EE) GLX: could not load software renderer
[   127.083] (II) GLX: no usable GL providers found for screen 0
The end result is the same, sluggish X desktop environment. I will try loading the fbturbo driver next to see if that makes a difference.

you need to install the d/llvm package.

yes this was the case and for the A20 I changed the configuration for it.

Ah, good call. That is what I get for not doing a full install!

I installed d/llvm and that error went away, but the previous error is now back again:

Code:
[   131.080] (II) Initializing extension GLX
[   131.080] (EE) AIGLX error: sun4i-drm does not export required DRI extension
[   131.412] (II) IGLX: Loaded and initialized swrast
[   131.413] (II) GLX: Initialized DRISWRAST GL provider for screen 0

Ah, I see you added the new drivers. I will grab those now, appreciated....

that's a little better
/etc/X11/xorg.conf.d/20-lima.conf
Code:
Section "ServerFlags"
        Option  "AutoAddGPU" "off"
        Option "Debug" "dmabuf_capable"
EndSection

Section "OutputClass"
        Identifier "Lima"
        MatchDriver "sun4i-drm"
        Driver "modesetting"
        Option "PrimaryGPU" "true"
EndSection
here's another tweak
Code:
echo -e '#!/bin/sh\n\nexport vblank_mode=0\n > /etc/profile.d/vblank.sh
echo -e '#!/bin/csh\n\nsetenv vblank_mode "0"\n > /etc/profile.d/vblank.csh
chmod +x /etc/profile.d/vblank.{csh,sh}
after that restart Xorg

glxgears before changing ~56fps after ~200-400fps

Hmmm, well... I have run out of things to try.

The next kernel with the tweaks you provided works somewhat, but the sluggish desktop is still an issue. Compared to my working image from a few months ago, it is a serious degradation of performance. Can we just turn off the 3D acceleration? I am used to not having it, and would not miss it if turned off. Besides, it is not fully developed yet for A64, is it? I am still getting the sun4i-drm error, and I have no clue how to try the fbturbo driver... how are you installing it? I see it in the git tree, is it an extras package or something? I know how to activate a driver in /etc/X11/xorg.conf.d/, but where do I get the driver from? Build from source, or is there a package somewhere?

I still cannot build the legacy kernel image. The build.log ends here, with no error messages at all:

Code:
    AR      drivers/video/built-in.a
    AR      drivers/built-in.a
The solution here is to use "make bzImage" instead of "make kernel". Would that apply here?

If I try switching the kernel version, the patches no longer apply correctly. I am guessing that the patches are version-specific, yeah? Hmmm...

Okay, back to *real* work... more later. thanks.

it is possible, but as for me it gets worse.

see errors much higher or install /config/environment/00-environment.conf CTHREADS=" -j1 "

Well, I got fbturbo installed (thanks again), but my first attempt at launching Xfce was a disaster.

Black screen, could not switch to another terminal, had to do a hard reset. Xorg.0.log spit out a bunch of scary stuff about FBTURBO when I looked at it from another OS:

So, it seems to have tried to load the driver, but never made it to the desktop. Any idea what might have gone wrong?

I only tried it on H3 and it worked.
