Not possible, at least from my end.

We lack the time required to implement this, as we are forced to focus on other items, marking as closed.

[purist69]

Libreelec was able to get this working.... Is this because Libreelec leverages Ubuntu?

[vitaliy-kuzmich]

please explain how I can enable video acceleration on this board ? Is it even possible ?

[josemahj]

there are any new with this?

@josemahj
Could you please try the following (this is Ayufans Rock64 repo which now has arm64 packages): https://launchpad.net/~ayufan/+archive/ubuntu/rock64-0.9-ppa

• This installs the base Mali driver for Rock64.

Then it depends on which software you use. E.g. the following should install/reinstall the X.org Xserver with hardware acceleration:

apt install --reinstall xserver-common xserver-xorg-core

Or simply run apt full-upgrade to check for updates of installed packages which should be all presented on Stretch.
Additional GPU-accelerated packages are available as well, check the link above.

[josemahj]

@MichaIng I get

The following packages have unmet dependencies:
 libmali-rk-utgard-450-r7p0 : Depends: libdrm2 (>= 2.3.1) but it is not going to be installed

when try install driver...

Then I try libdrm2 and

The following packages have unmet dependencies: libdrm2 : Depends: libc6 (>= 2.29) but 2.24-11+deb9u4 is to be installed

[MichaIng]

@josemahj
Thanks, let me have a look, there is a Bionic repo as well. Depends: libc6 (>= 2.17) that should work.
Please try:

echo 'deb http://ppa.launchpad.net/ayufan/rock64-0.8-ppa/ubuntu bionic main' > /etc/apt/sources.list.d/dietpi-rock64-gpu.list
cat << _EOF_ > /etc/apt/preferences.d/dietpi-rock64-gpu

EndSection

• But I already see that there are other packages that depend on libc6 >= 2.27, so e.g. ffmpeg must not be installed from there.

So we can only guarantee that this install works when we provide those packages individually instead of from the repo, so we know the dependencies are fulfilled by Debian Stretch. Finally a new Buster-based Rock64 image is required anyway which at least then fully supports the Bionic repo, sadly still not the Disco repo, since libc6 v2.28 is shipped.

[MichaIng]

@josemahj
Ah damn, this due to a package difference between Ubuntu (what this repo is made for) and Debian. On Ubuntu libegl1-mesa is just a transitional package for libegl1 and itself does not contain any library files. On Debian this change is done since Buster, but not yet on Stretch.

Okay but it's available as transitional package via backports: https://packages.debian.org/stretch-backports/libegl1-mesa
Please try:

apt purge libmali-rk-utgard-450-r7p0
apt install libegl1/stretch-backports
apt install libmali-rk-utgard-450-r7p0

Good to know about this package transition, will implement it into dietpi-software as well as the backports install of libegl1: https://github.com/MichaIng/DietPi/commit/f2ef6bd89bc65a47b543811201eceb5ccb80c6b9

[josemahj]

ok, everything is done. Now, trying to install ffmpeg

[MichaIng]

@josemahj
I guess installing ffmpeg from this repo is not possible, again due to incompatibility with libc6 from Debian repo. I guess you need to remove the repo again and go with ffmpeg from Debian. I hope it uses the installed GPU drivers. Would be also interesting in how far the desktop (and other Xserver-based applications) benefits from the driver/xorg.conf.

As said, for our implementation, if at least the driver/packages themselves successfully accelerate Xserver applications, we'll provide them separately from our server and not via repo (due to Ubuntu vs Debian imcompatibility).

---

The ARMbian community packaged some drivers and media software with GPU support as well: https://forum.armbian.com/topic/9310-rk3328-media-script-rock64-renegade/
However they as well mention Ubuntu to be required, but AFAIK the packages do not have dependencies, so that it might work. However the package versions are a bid outdated.

---

The source for RK3399 and ASUS TB drivers is RockChip thenselves. The problem is that they offer arm64 packages only for RK3399 (Mali T864 GPU): https://github.com/rockchip-linux/rk-rootfs-build/tree/master/packages/arm64/libmali
For Rock64/RK3328/Mali450 they only offer armhf (ARMv7) packages sadly: https://github.com/rockchip-linux/rk-rootfs-build/tree/master/packages/armhf/libmali
AFAIK they do not work with arm64 Xserver/applications then, but could be tested. E.g. for x86_64 PCs we as well install some Nvidia i386 driver, but I am not sure if this is only to satisfy dependencies or if this is really used by applications, when build for x64. EDIT on this: It is to run i386-only Steam, not required for anything else.

[josemahj]

could
this https://github.com/rockchip-linux/rk-rootfs-build/tree/master/packages/arm64/libmali
or
this https://forum.armbian.com/topic/9310-rk3328-media-script-rock64-renegade/
help?

[MichaIng]

@josemahj
The first link does not contain the required Mali 450 (Utgard) drivers, which are only available for armhf: https://github.com/rockchip-linux/rk-rootfs-build/tree/master/packages/armhf/libmali
See my post above, probably the armhf package, after dpkg --add-architecture armhf, will work, but requires testing.
The Armbian media script should work, but is very outdated.

[gprst]

Hi, I would be willing to help for testing. I typed in the dpkg --add-architecture armhg command, but I am very new to this kind of architecture-tweaking thing ; could you tell me which .deb file to install, and how to test if it works ?

[MichaIng]

@gprst
The test would be this:

1. Install a desktop, e.g. via dietpi-software or manually.
2. Assure glxgears and es2gears are installed: apt install mesa-utils mesa-utils-extra
3. Test glxgears and es2gears for frame rates and it they work at all.
4. Install the mentioned Mali GPU driver:

dpkg --add-architecture armhf
cd /tmp
wget https://github.com/rockchip-linux/rk-rootfs-build/raw/master/packages/armhf/libmali/libmali-rk-utgard-450-r7p0_1.7-1_armhf.deb
dpkg -i libmali-rk-utgard-450-r7p0_1.7-1_armhf.deb
rm libmali-rk-utgard-450-r7p0_1.7-1_armhf.deb
cd /usr/lib/arm-linux-gnueabihf
ln -sf libMali.so libEGL.so.1.1.0
ln -sf libMali.so libEGL.so
ln -sf libMali.so libEGL.so.1.0.0
ln -sf libMali.so libEGL.so.1.4
ln -sf libMali.so libEGL.so.1
ln -sf libMali.so libGLESv2.so
ln -sf libMali.so libGLESv2.so.2.0
ln -sf libMali.so libGLESv2.so.2.0.0
ln -sf libMali.so libGLESv1_CM.so
ln -sf libMali.so libGLESv1_CM.so.1
ln -sf libMali.so libGLESv1_CM.so.1.1

1. Test again glxgears and es2gears for frame rates and compare with results above.

[gprst]

Okay ; so here's how it went :

• I had an average of about 145 FPS with glxgears and about 155 FPS with es2gears on the first run
• I got the following error when running the second dpkg command :

dpkg: dependency problems prevent configuration of libmali-rk-utgard-450-r7p0:armhf:
 libmali-rk-utgard-450-r7p0:armhf depends on libc6 (>= 2.4).

Errors were encountered while processing:

• I tried to install libc6 or libdrm2 but got told that these packages were already on there newest versions, 2.24-11+deb9u4 for libc6 and 2.4.74-1 for libdrm2, but also on both tries have been suggested to type in apt --fix-broken install, so I typed in the command, and the required dependencies got installed ! :tada:
• on the second run, I got :
  
  
  
  • an average of about 144 FPS with glxgears, that then rose up to about 160 FPS, then about 150 FPS, then I stopped
  
  
  • an average of about 165 FPS with es2gears
  
  

I don't know if the frame rate difference is significant, nor if I actually got the Mali GPU driver to work. Could you tell ?

[MichaIng]

@gprst
Okay many thanks for testing. To the armhf package seems to depend on the armhf versions of the libraries as well. On your arm64 system the arm64 versions are installed. Quick result is that we have no pre-compiled Mali drivers for Rock64 currently. We could compile them ourself or use the quite outdated version from the Armbian community.

Someone with a bid more experience in Linux graphics and compiling and a Rock64 board would be very helpful. I can only provide the theoretical steps but especially when compiling usually one runs into several errors due to missing development/header packages and such until figuring out everything, especially since RockChip sources are not aimed for Debian only but Ubuntu as well.

[MichaIng]

Okay, instead of messing around with the proprietary driver, we'll go for FOSS mesa, which starts to support Mali450 with newest version: https://wiki.debian.org/PanfrostLima

I'll have a look if I can compile those for Debian Buster arm64 either for ROCK64 in particular or to include generic support for all our supported SoCs or even x64_86?: https://docs.mesa3d.org/install.html

If anyone can or wants to help, highly welcome.

Here the build log to check/compare compile time options and results: https://buildd.debian.org/status/fetch.php?pkg=mesa&arch=arm64&ver=20.1.2-1&stamp=1593073012&raw=0

Another idea would be to provide an early Bullseye image for that device.

[MichaIng]

NanoPi NEO3 uses the same SoC, hence requires the same GPU support: http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO3#Hardware_Spec

EDIT: Ah its a headless SBC, however for VNC and video coding for remote playback it may still be interesting.
