Hello, I have read a lot to get panfrost ins a s912 tv box, but always with same result... llvmpipe. I don t know how to make it works... I have a H96 pro plus 3GB 32GB, S912. I tried with a lot balbes150 images, Single Armbian image for RK + AML + AW and S9xx images. Now with 20.5.2, 5.7 focal. malloc@arm-64:~$ inxi -F System: Host: arm-64 Kernel: 5.7.0-rc1-arm-64 aarch64 bits: 64 Desktop: Xfce 4.14.2 Distro: Ubuntu 20.04 LTS (Focal Fossa) Machine: Type: ARM Device System: Amlogic Meson GXM (S912) Q200 Development Board details: N/A CPU: Topology: 8-Core (2-Die) model: ARMv8 v8l variant: cortex-a53 bits: 64 type: MCP MCM Speed: 1512 MHz min/max: 100/1512:1000 MHz Core speeds (MHz): 1: 1512 2: 1512 3: 1512 4: 1512 5: 1000 6: 1000 7: 1000 8: 1000 Graphics: Device-1: meson-gxm-dw-hdmi driver: meson_dw_hdmi v: N/A Device-2: meson-gxm-mali driver: panfrost v: kernel Display: x11 server: X.org 1.20.8 driver: modesetting resolution: <xdpyinfo missing> OpenGL: renderer: llvmpipe (LLVM 9.0.1 128 bits) v: 3.3 Mesa 20.1.0-devel (git-cdc4377 2020-04-18 focal-oibaf-ppa) Audio: Device-1: meson-gxm-dw-hdmi driver: meson_dw_hdmi Device-2: gx-sound-card driver: gx_sound_card Sound Server: ALSA v: k5.7.0-rc1-arm-64 Network: Device-1: meson-gxbb-dwmac driver: meson8b_dwmac IF: eth0 state: up speed: 1000 Mbps duplex: full mac: 78:c2:c0:9a:80:f1 Device-2: pwm-clock driver: pwm_clock Drives: Local Storage: total: 58.84 GiB used: 2.96 GiB (5.0%) ID-1: /dev/mmcblk0 vendor: SanDisk model: SL32G size: 29.72 GiB ID-2: /dev/mmcblk1 model: 032G74 size: 29.12 GiB Partition: ID-1: / size: 28.39 GiB used: 2.87 GiB (10.1%) fs: ext4 dev: /dev/mmcblk0p2 ID-2: /boot size: 511.0 MiB used: 65.5 MiB (12.8%) fs: vfat dev: /dev/mmcblk0p1 ID-3: /var/log size: 48.4 MiB used: 2.3 MiB (4.8%) fs: ext4 dev: /dev/zram0 Sensors: Missing: Required tool sensors not installed.

The Panfrost project building a free, Open Source graphics driver for modern Mali GPUs has reached a new milestone: the first 3D render, including basic texture support, on a Bifrost chip (Mali G31)! View the full article

@c0rnelius, that did the trick, and made it possible to upgrade my Debian Buster install to 23.02.2 Kernel 6.1.11 and have HDMI Audio! Thanks a bunch!! 😀 I will try this solution on Debian Bullseye as well. Now it's time to figure out how to enable my Panfrost driver in place llvmpipe on Buster, but that's another issue for another thread.

I have the same issue using Debian Buster, and the HDMI audio only works up to kernel 5.10.102. Anything past that, and all I get is dummy audio. I have found Ubuntu Focal will work with HDMI audio with the MATE desktop up to Kernel 5.10.102 as well, plus you gain the ability to use the Panfrost GPU driver. I think there may be an issue with the DTB /Uboot files past kernel 5.10.102, so I set Armbian config to freeze kernel and firmware upgrades until I know the problem has been rectified. Kind of a bummer since I have a Edimax Wifi 5 dongle that seems to require Kernel 6.1 to operate.

Hi all. I'm working on a script that can install different Linux gaming tools like Box86, Box64, PPSSPP, ... For now it can only install box86 and box64. There is also an issue installing wine, so this doesn't work either. https://github.com/NicoD-SBC/armbian-gaming Download and unzip and run script : sudo /bin/bash ./armbian-gaming.sh When ready I'll make a video about it and give more info. I've tested it on the PineBookPro with Hirsute. With the Odroid N2+ you need to activate panfrost, install dependecies for N2+, and then install box86. Tho it didn't work as it should. If "install box86" gives a build error, try the dependencies for N2+ and try "install box86" again. Please let me know your experiences on other systems.

Well, this isn't quite the recommendation (afaik, did something change from the 5V / 4A Type C?). Power Supply is absolutely critical during boot times, and even 5V/3A was not enough when running a desktop, mentioned many many times. I also had to learn this the hard lesson 😉 Try to get 5V/4A Type C to be sure. What happened to me one time after installation was a faulty line in /etc/fstab was XXXX_EXAMPLE_UUID / ext4 defaults,noatime,commit=600,errors=remount-ro,x-gvfs-hide 0 1 instead of UUID=XXXX_EXAMPLE_UUID / ext4 defaults,noatime,commit=600,errors=remount-ro,x-gvfs-hide 0 1 which you could check. @balbes150 Did you compile mesa from here for kernel 6.2 builds: https://gitlab.freedesktop.org/panfrost/mesa/-/tree/panfrost/v10-wip , I guess this was https://gitlab.com/panfork/mesa (branch csf) used for legacy kernel?

Panfrost's ES 3.0 support has landed in upstream Mesa and works with a mainline Linux kernel. The support is still early, but if you're feeling adventurous, feel free to give it a try on your favourite ES 3.0 applications and games. View the full article

SEE: fellow member @mcerveny efforts I tried to setup/enable some other components and I am successful with upstream linux kernel 6.2RC5: - displayengine (drm, fb, mixer, tcon, hdmi) (seems to have some I2C/EDID problems) - videoengine (cedrus) (in testing now) - gpu (3d mali, panfrost)

Anybody have success with panfrost? kernel module and userspace module I have firefly 3399( 5.4.8-rockchip64) board And I don't see panfrost in dmesg or lsmod Any idea?

I am also experiencing the same issue - after reading through many previous forum posts regarding graphics & driver issues with the OPi3LTS I wasn't able to turn anything up. I've been trying to troubleshoot as best as possible over the last week or so and I haven't had any success - I don't have a lot of experience in this space so I'm pretty much starting from scratch myself. Any assistance at all would be appreciated, even a nudge toward some documentation for the Panfrost driver that might have further info regarding this error code.

Hello, I have a problem on my orange pi 3 lts. Namely, I have armbian 23.03 Jammy Xfce installed and on some screens it shows normally, on others the image does not appear. I also tried using the Uart converter and it loads everything normally, but then the following message starts appearing every second. [ 161.905394] panfrost 1800000.gpu: js fault, js=0, status=INSTR_INVALID_PC, head=0xa005bc0, tail=0xa005bc0

Found a simple way to disable video hardware acceleration. The ppa:liujianfeng1994/rockchip-multimedia installs a MPPE capable version of these codec libraries and they need to be downgraded. VLC does not respect the HW Acceleration checkboxes in this setup. It might also work to skip this repository when setting up the hardware and only do the panfrost part. The following should not remove half your packages. If you stumble on this later on, you can update the version numbers from https://packages.ubuntu.com/jammy/libavcodec58 sudo apt-get install libavcodec58=7:4.4.2-0ubuntu0.22.04.1 libavutil56=7:4.4.2-0ubuntu0.22.04.1 libswresample3=7:4.4.2-0ubuntu0.22.04.1 libavformat58=7:4.4.2-0ubuntu0.22.04.1 libpostproc55=7:4.4.2-0ubuntu0.22.04.1 libswscale5=7:4.4.2-0ubuntu0.22.04.1 Armbian is not the only distro I have tried. All the "official" distributions had these two problems, but cannot confirm they had wayland enabled. I can't understand why google finds so little for the above DMA error messages.

Hey, I'm experiencing graphics failures, accelerated decoding problems, flickering window decorations and shell hangups in Plasma. All events are associated with syslog entries: dma-pl330 fea30000.dma-controller: pl330_submit_req:1738 Try increasing mcbufsz (258/256) dma-pl330 fea30000.dma-controller: fill_queue:2264 Bad Desc(2) I've attached the whole system log in case someone is interested. Running Armbian 23.02.2 Jammy Linux orange 5.10.110-rockchip-rk3588 #23.02.2 SMP Fri Feb 17 23:59:20 UTC 2023 aarch64 Panfrost-mesa updated to HEAD. A very similar problem occurs with Orange Pi 5 Debian ready distro images, but the kernel version is very similar. What to do here? Build a Arduino TTL repeater and go to town with a kernel debugger on an unfamiliar architecture? Is my DMA controller broken? Armbian_OrangePI5_syslog.txt Xorg.0.log

@Kuu Tirronen Nice found that hack, but I'm questioning if you've followed the right steps, so which steps did you follow? Wayland will probably give better results, for hardware video decoding you'll need software that will make use of mpp. Amazingfate made a repo for jammy with panfork mesa and a repo with software build with rkmpp hw acceleration there are a few topics about this, also don't forget to install malirun from his repo, this will set the udev rules that's needed for hw acceleration. For Panfrost this option should be disabled: cat /boot/config* | grep CONFIG_DRM_IGNORE_IOTCL_PERMIT For mali blob you'll need the right driver and is not compatible with panfork mesa and not every driver supports X11.

Ohhhh with that one I now do get the GPU detected with glxinfo -B ! Nice one! [ I kept updating this maybe skip to the end for the success part? ] There are some very cool and strong graphical artifacts in some areas now and then and there's a error message from the glxinfo. Is there a device file I need to flip some permission on or something maybe?

Don't worry if this is eating up your time and you'd rather spend that on other things. If that's the case I'll just leave this until its more mature. If not I'm happy to keep trying stuff.

It seems my custom build Mesa was interfering even after I had reset the ld conf files + sudo ldconfig. Now I was able to run, > LD_LIBRARY_PATH="/usr/lib/aarch64-linux-gnu" glmark2-es2-wayland and without changing the default governor I got: glmark2 Score: 2189 Success!! There were still some strong glitching in the following, [jellyfish] [terrain] [refract] but maybe something in my own Mesa install still interefered. I still also get the DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied from glxinfo. UPDATE 3: After sticking the governor to performance glmark2-es2-wayland returns: glmark2 Score: 3455 A new record for me on this board! The other issues mentioned above are still there but maybe I'll have to re-run on a clean flashed SD card and see what goes away. That'll be for later because now I'm itching to try Dolphin again on this setup!

Hi I'm excited to try mesa Panfrost (not panfork) with this kernel and have managed to get a build. But I keep getting llvm instead of the GPU and was wondering if anyone know what I need to do? I'm using this config command: meson --prefix /usr --libdir lib -Dvulkan-drivers= -Dlibunwind=false -Dgallium-drivers=panfrost,kmsro,swrast -Dplatforms=x11,wayland -Dbuildtype=release -Degl=true -Dgles1=true -Dgles2=true build I'm also adding the /usr/lib and /usr/lib/dri paths to ld conf files and it seems they are found. But glxinfo still gives me just llvm. Cheers!

I need one more component working. 3D and OpenCL. Has anyone successfully installed Panfrost on a RK3399 board ? Update! I manged to build the Panfrost X11 driver. Here's how I did it: https://panfrost.freedesktop.org/building-panfrost-mesa.html Before you create the build directory update the meson_options.txt file change platforms from auto to x11 change dri_driver from auto to swrast change gallium-drivers to panfrost cd to the build directory meson .. . -Ddri-drivers= -Dvulkan-drivers= -Dgallium-drivers=panfrost -Dlibunwind=false --prefix=/{wherever you want} ninja install before you start a program export LD_LIBRARY_PATH=/{wherever your path is} glmark2-es2 When I get home from work I will test further. I will update later. I wanted to post just in case anyone else wishes to try it. I got to go to sleep, work tomorrow.

Added new versions of the mesa package and an archive to enable acceleration for wayland. To enable wayland acceleration, you need to replace the files in the /usr/lib/aarch64-linux-gnu directory with the contents of the archive (with file replacement). After that, acceleration will work with wayland. X11 and wayland acceleration works the same way on Debian Sid (the images are the same as Ubuntu). After starting the system and initial configuration, replace the files from the archive in the same way and acceleration will work. The results of running in Debian Sid Gnome for x11 and wayland. x11 ======================================================= glmark2 2023.01 =======================================================

I'm looking to try an OPi5 for GPGPU. After seeing trunk recently added the patches needed to use the "gofaster" option for panfork, and having seen reports of glmark2 scores of 4000 and 5000 while never coming close to that myself, I decided to pull together the various bits of info out there and just try all of the options. A number of things done below are often described vaguely -- hopefully it's helpful here to lay out a concrete set of steps to follow and what to expect. There are two options for accelerated video: panfork and ARM's closed source "blob" driver. With either option, it sounds like you should switch from X11 to Wayland. If you are looking at doing OpenCL or Vulkan, you will have to use the blob driver for the foreseeable future. FYI, OpenCL benchmarks at 470 Gflops single precision, 910 Gflops half precision. Option 1: Installing panfork This is pretty much explained on the project page for this SBC, but maybe it will help someone to see each step in detail. I started with installing the latest nightly build. Then I ran the following in a terminal: sudo add-apt-repository ppa:liujianfeng1994/panfork-mesa wget https://github.com/JeffyCN/rockchip_mirrors/raw/libmali/firmware/g610/mali_csffw.bin sudo cp mali_csffw.bin /lib/firmware/ sudo chmod 664 /lib/firmware/mali_csffw.bin sudo add-apt-repository ppa:liujianfeng1994/rockchip-multimedia sudo vi /etc/apt/preferences.d/rockchip-multimedia-ppu [save the following three lines in this file] Package: * Pin: release o=LP-PPA-liujianfeng1994-rockchip-multimedia Pin-Priority: 600 sudo vi /etc/apt/preferences.d/panfork-mesa-ppu [save the following three lines in this file] Package: * Pin: release o=LP-PPA-liujianfeng1994-panfork-mesa Pin-Priority: 600 sudo apt update sudo apt dist-upgrade sudo vi /etc/udev/rules.d/98-mali-accel.rules [save the following four lines in this file] KERNEL=="mpp_service", MODE="0660", GROUP="video" KERNEL=="rga", MODE="0660", GROUP="video" KERNEL=="system-dma32", MODE="0666", GROUP="video" KERNEL=="system-uncached-dma32", MODE="0666", GROUP="video" RUN+="/usr/bin/chmod a+rw /dev/dma_heap" sudo apt install chromium-browser=$(apt-cache show chromium-browser|grep Version|grep rkmpp|cut -d " " -f2) chromium-codecs-ffmpeg-extra=$(apt-cache show chromium-browser|grep Version|grep rkmpp|cut -d " " -f2) libv4l-rkmpp v4l-utils sudo ln -s /lib /usr/lib64 cd /usr/lib64/ && sudo ln -s aarch64-linux-gnu/libv4l2.so.0.0.0 libv4l2.so sudo vi /etc/rc.local [add the following six lines to this file] echo dec > /dev/video-dec0 chown root:video /dev/video-dec0 chmod 0660 /dev/video-dec0 echo enc > /dev/video-enc0 chown root:video /dev/video-enc0 chmod 0660 /dev/video-enc0 sudo vi /etc/chromium-browser/default CHROMIUM_FLAGS="--use-gl=egl" sudo apt install gnome-shell ubuntu-gnome-desktop glmark2-es2-wayland sudo reboot From there you are running Wayland and the panfork accelerated driver. glmark2 benchmarking of various options for panfork: For this, you need to use glmark2-es2-wayland (installed above). First, I ran glmark2 on the system fresh from the above reboot: foobar@orangepi5:~/install$ glmark2-es2-wayland ======================================================= glmark2 2021.02 ======================================================= OpenGL Information GL_VENDOR: Panfrost GL_RENDERER: Mali-G610 (Panfrost) GL_VERSION: OpenGL ES 3.1 Mesa 23.0.0-devel ======================================================= . . .

It beats the out of the box score for the Khadas Edge2. Option 2: installing the ARM blob driver I also gave this a try -- partly due to interest in evaluating OpenCL performance, and partly to see if the vendor-provided driver could go even faster. I couldn't find a decent set of instructions for how to install the blob driver, so I took a different approach -- I used the package files produced by Khadas for building their Edge2 Ubuntu images. Maybe there are packages already available through Armbian, and I just couldn't identify them. The package files can be found in these four repos: https://github.com/numbqq/mali-debs https://github.com/numbqq/mpp-rockchip-debs https://github.com/numbqq/rga-rockchip-debs https://github.com/numbqq/gstreamer-rockchip-debs Altogether, I found the following package files: gstreamer1.0-rockchip1_1.14-5_arm64.deb rockchip-mpp-dev_1.5.0-8_arm64.deb rockchip-mpp-sample_1.5.0-8_arm64.deb rockchip-mpp_1.5.0-8_arm64.deb rockchip-rga-dev_2.2.0-6_arm64.deb rockchip-rga-sample_2.2.0-6_arm64.deb rockchip-rga_2.2.0-6_arm64.deb linux-gpu-mali-wayland_1.0-g610-20220510_arm64.deb The last one had to be installed with "--force-overwrite" because of a file duplicated with an existing package. I also installed the ubuntu-desktop package to switch over to Wayland. On my first login, "echo $XDG_SESSION_TYPE" reported x11. I logged back out, and logged in again checking the gear icon to make sure the Wayland-related one was selected. I don't know if the gear icon was needed, but that time Wayland was active. glmark2 benchmarking of various options for the blob driver: First, I did a run with the default governor settings: foobar@orangepi5:~/install$ glmark2-es2-wayland arm_release_ver of this libmali is 'g6p0-01eac0', rk_so_ver is '6'. arm_release_ver of this libmali is 'g6p0-01eac0', rk_so_ver is '6'. ======================================================= glmark2 2021.02 ======================================================= OpenGL Information GL_VENDOR: ARM GL_RENDERER: Mali-LODX GL_VERSION: OpenGL ES 3.2 v1.g6p0-01eac0.ba52c908d926792b8f5fe28f383a2b03 ======================================================= . . .

Awesome is this Panfrost-Panfrost, ie not Panfork? Id'e love to try it but do not have experience trying out different kernels. Ive seen the/a 'midstream' kernel and that it includes the wip/new pancsf. Could you make some 1-2-3 steps instruction for making an install that has this? I would really love to try it.
