mainline kernel + H3-GPU + X11-window/glmark2 extremly slow #23

wuweidong0107 · 2017-12-27T01:50:08Z

Hi,guys
I am testing mainline kernel + H3 + GPU by follow repo:
https://github.com/mripard/sunxi-mali.git
https://github.com/free-electrons/mali-blobs
https://github.com/mripard/xf86-video-armsoc

About kernel:
I've done these step:

added mali node in dts
cherrypicked this commit(nextthingco/linux@e390023)
CONFIG_DRM_FBDEV_OVERALLOC=200

About rootfs:
I've done these step:

install xf86-video-armsoc:
$ git clone https://github.com/mripard/xf86-video-armsoc
$./autogen.sh
$ apt-get install libudev-dev
$ make && make install
$ cp /usr/local/lib/xorg/modules/drivers/* /usr/lib/xorg/modules/drivers/
$ cp xorg.conf /etc/X11/
cp x11_dma_buf/*.so* rootfs/usr/lib/

I am able to run glmark2-es2.But it is extremly slow. Only 15 fps....Any hints will be appreciated.

Hi @wuweidong0107 can you paste in your x11 log? It seems x11 is using swrast or something like that instead of Mali for rendering.

@wuweidong0107 it seems you didn't compile armsoc_dri.so since it complains it can't find it

wuweidong0107 · 2017-12-28T01:41:47Z

Is armsoc_dri.so important? Where can I find its sources?

giuliobenetti · 2017-12-28T06:54:31Z

It is the interface for using kernel dri.
xf86-video-armsoc has the sources, but when compiling it, you need libdri already compiled for target.

wuweidong0107 · 2017-12-28T08:56:21Z

I prefer to disable AIGLX by changing my xorg.conf:
Section "Device"
Identifier "Allwinner sun4i DRM driver"
Driver "armsoc"
Option "DRI2" "false"
EndSection

Section "ServerFlags"
Option "AIGLX" "off"
EndSection

Section "Extensions"
Option "Composite" "Disable"
EndSection

Am I on the right path?

giuliobenetti · 2017-12-28T09:01:41Z

You need DRI2 set to true to have HW acceleration.
Then x11 will complain there is not armsoc_dri.so but you need it to interface with kernel dri.
so retry to:

compile libdri and install it
recompile xf86-video-armsoc and install it
check armsoc_dri.so is present on both host and target

Then it should work properly.
I don't know AIGLX to tell the truth

wuweidong0107 · 2017-12-28T09:47:56Z

Just finish your suggest. No luck

I compile this repo on my H3 board:
git clone https://github.com/robclark/libdri2
cd libdri2
./autogen.sh
./configure --prefix=/usr
make && make install && ldconfig
recompile xf86-video-armsoc, but not find armsoc_dri.so:
autoreconf -v -i
./configure
apt-get install libudev-dev
make && make install
cp /usr/local/lib/xorg/modules/drivers/* /usr/lib/xorg/modules/drivers/

the X11 windows is still lagging

giuliobenetti · 2017-12-28T09:50:56Z

Can you pastebin xf86-video-armsoc configure and build log? We need to understand if it found libdri correctly.
also pastebin x11 log.
thanks

wuweidong0107 · 2017-12-28T10:02:37Z

giuliobenetti · 2017-12-28T11:21:28Z

Can you also post xf86-video-armsoc build log?
I suspect you need to configure it with:
./configure --with-drmmode=sun4i

Thanks

wuweidong0107 · 2017-12-29T02:31:14Z

I run ./configure --with-drmmode=sun4i. configure log is here:

I notice that WARNING: unrecognized options: --with-drmmode...

"make && make install" 's log is here:

the X11 windows is still lagging.

It complains about:
[ 12.904] (EE) AIGLX error: dlopen of /usr/lib/arm-linux-gnueabihf/dri/armsoc_dri.so failed (/usr/lib/arm-linux-gnueabihf/dri/armsoc_dri.so: cannot open shared object file: No such file or directory)
[ 12.904] (EE) AIGLX: reverting to software rendering

It's looking for armsoc_dri.so in different folder than yours.
Try create symbolic link with:
ln -s /usr/lib/arm-linux-gnueabihf/dri/armsoc_dri.so pointing where you have your real armsoc_dri.so
In this way AIGLX should find library.
It's strange, because for the rest it can find it.
But give it a try.

Let me know

wuweidong0107 · 2017-12-29T09:33:46Z

In my rootfs there is no armsoc_dri.so in any directory...still don't know how to get one...

giuliobenetti · 2017-12-29T09:42:43Z

Can you find armsoc_drv.so depencies?
Like:
readelf -d elfbin armsoc_drv.so
or
ldd armsoc_drv.so

At least we check if that library expects armsoc_dri.so or something else.
Unfortunately I don't have environment setup to give a try.

Let me know

Well, it seems there's no direct dependency with armsoc_dri.so
So, try to launch strace when starting X11 and pastebin log.
In this way we can check all syscalls, included when and who tries to dlopen armsoc_dri.so

I've had similar issues when the GPU clock was not configured properly. can you paste the output of /sys/kernel/debug/clk/clk_summary while your GPU tasks are running?

wuweidong0107 · 2018-01-05T10:01:45Z

cat /sys/kernel/debug/clk/clk_summary while running glmark2-es2.
clk_summary.txt

wuweidong0107 · 2018-01-05T10:06:41Z

glmark2-es2.log
score 16...very awkward

giuliobenetti · 2018-01-05T15:35:03Z

@mripard could it be AIGLX error inside his x11 log?
https://github.com/mripard/sunxi-mali/files/1590967/Xorg.0.log

It seems he doesn't have armsoc_dri.so properly compiled or installed.
So AIGLX falls back to SWRAST.
Or it isn't mandatory to have armsoc_dri.so (it should be user-space driver to interface with DRI, right) ?

mripard · 2018-01-05T20:52:55Z

@wuweidong0107 the frequencies look correct. IIRC, glmark-es2 has an option to do some off-screen rendering, can you try to use that and report the results? Are you running it fullscreen?

@giuliobenetti this message shouldn't cause any harm. The glmark2-es2 logs show that we're using the correct opengl provider anyway

wuweidong0107 · 2018-01-08T01:45:35Z

Can anybody offer a rom that use mainline kernel with x11+gpu for H3 ?

mripard · 2018-01-08T08:38:05Z

Wait, what have you been testing if you don't have one?

wuweidong0107 · 2018-01-08T09:33:25Z

....Mine is extremly slow. And I heard yours works perfectly. So I would like to test yours...

mripard · 2018-01-12T10:16:20Z

I never tested it on an H3

Icenowy · 2018-01-17T13:07:32Z

@mripard I think currently the code didn't wire the PMU interrupt.

I met this on H5, which I slightly modified for Mali-450 --the driver waits for PMU interrupt, but as it's not wired by the driver it cannot get it, so it timeout and gets slow.

mripard · 2018-01-17T14:23:57Z

Can you test the branch test-pmu I just pushed?

The other results I asked for would still be valuable.

maximst · 2018-02-22T19:01:49Z

I have tha same problem on H3 armbian. When i run glxgears i get the errors:

DISPLAY=:0 glxgears

giuliobenetti · 2018-02-22T19:04:25Z

You don't have sun4i-drm.so compiled probably.
Here's the comment above on how to be sure to be compiled:
#23 (comment)

mripard · 2018-02-23T09:06:44Z

glxgears is an OpenGL application, the Mali supports only the Open GL ES API. So, it's not the same issue.

maximst · 2018-02-23T14:49:35Z

@wuweidong0107 what distributive are You using? You can change root password to 1234 and create dd image for me? Please, if not difficult.
Thank, You!

timdorohin · 2018-08-30T13:58:56Z

just use glmark2-es2 --fullscreen
armsoc can't use G2D on mainline kernel, so buffers are composited by CPU (slow)
in fullscreen mode it use buffer swap - zero-copy (fast)

ghost · 2018-09-04T10:27:57Z

I also noticed before that retroarch runs faster in fullscreen. Tim Dorohin is right.

cuu · 2018-11-02T15:29:13Z

@wuweidong0107 which kernel are you using for testing?

wuweidong0107 · 2018-11-05T01:41:04Z

@cuu base on:
git clone https://github.com/friendlyarm/linux.git -b sunxi-4.14.y --depth 1

davidebeatrici · 2019-03-21T23:49:53Z

OpenGL applications can be offloaded to the GPU with https://ptitseb.github.io/gl4es.

I'm encountering the exact same issues as @wuweidong0107 on Armbian Stretch, with kernel linux-4.19.25-sunxi.
