刚入手VIM3PRO
打算拿来做车牌人脸识别这类应用
但是在配置Ubuntu时我感觉不到装了GPU驱动…
是目前阶段Ub20下无法驱动或有个开关?
还是需要自行编译Mali-G52/MP4的驱动
因为识别的同时还要负责视频预览输出
如果没有GPU驱动，怕纯靠CPU处理压力太大
当前的GPU没有Panfrost驱动程序，它正在运行libmali驱动程序，因此无法正确使用GPU。GPU的Panfrost驱动程序已经宣布即将推出…
VIM3 GPU驱动在4.9内核下是已经集成了的。但是只有fbdev的，没有X11的，如果你说的是在桌面环境下，那么目前是没有GPU驱动的。后面会有开源的GPU驱动Panfrost支持X11，但目前还处于早期开发阶段。
Hi everyone.
It looks like 5.7.0-rc7 kernel already has the panfrost drm support.

git mesa already has G-52 support too (it’s still likely initial and the perfomance isn’t optimal)
I’ve tested kmscube - it works great.

It’s also possible to play supertuxkart under wayland with nice perfomance ( colors are wrong too)
So imho the problem is in xorg server (or it’s config), but ubuntu is not my system, i’m not sure if any lib may be missing, so i’m helpless until i can run my favorite distro (WIP).
If anyone knows how to verbose Xorg log to see more details - feel free to share

@DeadMeat are the results for 1080p FHD resolution ?
No, my display is 1280x1024, but glmark runs in window, not fullscreen.
I can also test it in 1080 and 4k, but a bit later.
And almost forgot, you should set PAN_MESA_DEBUG=bifrost in OS enviroment
Also i use ubuntu 18.4, and didn’t tested 20 yet.

Please test and tell your results, Thank you!
Done with 4k. Can’t test 1080 in weston - i dont know how to change resolution

The red and blue colors are switched.
Also HW acceleration works in Xorg under root so probably it’s a /dev/dri/* premissions issue.
SW glxgears -
HW glxgears
blue and red gears are with wrong color.
extreme tux racer unger X11, under root
UPD:
HW acceleration using Xorg is not very stable. Got a couple of freezes on glxgears run.
Also i’ve tried to set chmod 0666 /dev/dri/* but didn’t get HW working in Xorg under user.

@DeadMeat for fullscreen you just need to append --fullscreen to the end of the starting command,
i.e

Its only a little more than before 
refer to my old benchmarks done…

Do i understood correct, that your benchmark was done using blob arm driver?
GLmark Score:48
1080p full screen score:29
Fullscreen:
glmark2 Score: 62
Overal 1080 fullhd score almost twice higher
windowed mode:
glmark2 Score: 495
seems to be almost 10x higher.
As for me - nice boost
It looks not quite enought for 4k, but 1080 semms good enought for beta/testing driver.
Ive try to get panfrost to work on vim3 using mesa-20.0.3-devel but it is still on llvm and idk why I cannot get it to work.
How did you get it to work?
yes it was the blob arm driver, or fbdev drivers,
also for me in windowed mode it was 48, and in your testing it was 480+ so yes, a 10x score increase 
…
but it doesn’t mean 10x graphics performance… can it ? 
Probably it’s a typo, but i use mesa-20.3.0-devel (latest git).
Building mesa (following config works for me):
cd ./mesa
meson ./build --buildtype plain --libdir lib/aarch64-linux-gnu --localstatedir /var/lib --prefix /usr --sysconfdir /etc --wrap-mode nodownload -Dplatforms=surfaceless,x11,drm -Dllvm=true -Dlmsensors=false -Dlibunwind=false -Dgallium-nine=false -Dgallium-va=false -Dgallium-vdpau=false -Dgallium-xa=false -Dgallium-xvmc=false -Dgallium-opencl=disabled -Dosmesa=none -Dbuild-tests=false -Dglx=dri -Dshared-glapi=enabled -Ddri3=true -Degl=true -Dgbm=true -Dgles1=disabled -Dgles2=enabled -Dglvnd=false -Dselinux=false -Dvalgrind=false -Ddri-drivers= -Dgallium-drivers=kmsro,panfrost,swrast
ninja -C ./build install
Then you shold export the enviroment var PAN_MESA_DEBUG=bifrost for ubuntu/debian - in /etc/environment.d/panfrost-enable-bifrost.conf
After that it shold work, under X11 with root privileges. Also you can use kmscube for testinf without X11.
Feel free to ask on any problems.

Why not ;), btw in full screen it’s just 2x. We need some “real-life” test, e.g. games, i’ve tried to run openarena, but got segfault, looks lite the driver is not yes so functional.
but still I have high hopes for the drivers 
,
in comparison we are at about half the performance of the Odroid N2 in performance,

You can expect some instability and breakage in mesa master as things run-up to mesa forking 20.3 in the next week (Nov 4th IIRC). The current goal is to release Bifrost support (no debug export needed) but that means things are moving fast. The driver still has a long way to go before it reaches proper conformance and performance levels but it’s improving rapidly.

I was able to get panfrost to work on vim3 but only on Wayland with pan_debug.
It is very unstable but looks promising as some of the kde animations are very smooth.
At current stage it is not usable as it keeps flicking with many fonts missing and keeps crashing the shell.
Let’s wait for the official release
