modprobe mali

modprobe: FATAL: Module mali not found in directory /lib/modules/4.14.18-sunxi

insmod /lib/modules/4.14.18-sunxi/extra/mali.ko

insmod: ERROR: could not insert module /lib/modules/4.14.18-sunxi/extra/mali.ko: Invalid module format

[giuliobenetti]

Can you provide build log? And also a objdump -h of KO module? Thanks

[sergey-suloev]

@Marx86 can you check that depmod was successful for mali.ko ?
Why on earth you need to load it manually instead of using the device tree?

[maximst]

I compiled the module like this:

apt install quilt linux-source-4.14.18-next-sunxi
untar the linux source archive
export KDIR=/usr/src/linux-source-4.14.18-sunxi
./build.sh -r r6p2 -b
./build.sh -r r6p2 -i

Maybe I сan do something wrong?

Mali installed in to /lib/modules/4.14.18+ and i created symlink /lib/modules/4.14.18-sunxi/extra -> /lib/modules/4.14.18+/extra

dmesg says:
mali: version magic '4.14.18+ SMP mod_unload ARMv7 thumb2 p2v8 ' should be '4.14.18-sunxi SMP mod_unload ARMv7 thumb2 p2v8 '

[giuliobenetti]

You need exactly same kernel version 4.14.18+ sources. This is why it refuses to load

[giuliobenetti]

And keep in mind that next branch is not stable, it's only a patch collector. You should use mainline versions.

[maximst]

@giuliobenetti
I try build module with kernel /usr/src/linux-source-4.11.12-sun8i but module compiled into /lib/modules/4.11.12+ not in /lib/modules/4.11.12-sun8i

# uname -a
Linux orangepipc 4.11.12-sun8i #2 SMP Wed Nov 22 13:50:32 CET 2017 armv7l armv7l armv7l GNU/Linux

[maximst]

Maybe i need rebuild kernel from /usr/src/linux-source-4.11.12-sun8i and install it?

[maximst]

Or i need build mainline kernel from kernel.org without all sunxi patches?
But then the specific periphery will not work, like HDMI, IR receiver, etc. or i wrong?

[giuliobenetti]

I've never faced this kind of problem. But if you build using 4.15 you should have almost every peripheral working. Which SoC are you using?

[giuliobenetti]

Sun8i seems A23 or A33. So there should be everything you need. Take a look at Linux-sunxi. Org on mainline effort section to see what is supported or not by which version.

I changed kernel version in files include/generated/utsrelease.h and include/config/kernel.release
and module has loaded with insmod after build, but i dont understand how configure of xorg.conf for using mali driver r6p2.
I think what this is wrong config, which the work with p3r0:

Good to know the hack of kernel version.

For X11 you need some more steps:

• cherry pick this commit(nextthingco/linux@e390023)
• 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/

Then you should have it working.

[maximst]

This is commit for sun4i (A10)? But i use the sun8i (H3) and kernel 4.14.18. And xf86-video-armsoc supported only pl111, exynos, sun4i. Or i wrong?
Sorry, if i asking stupid questions.

[giuliobenetti]

Nobody is stupid if ask something. If someone thinks to know everything is stupid :)

Philosophy apart, sun4i is compatible with Sun8i, you can check that inside drm kernel sources. Idem for xf86-video-armsoc x11 driver. This avoid having every SoC family using different files and inside driver you can distinguish which SoC you're using by checking quirks.

[maximst]

Thank, You!
I builded and installed armsoc with this steps:

apt install m4 xutils-dev libudev-dev autoconf autogen libudev-dev libtool xorg-dev
git clone https://github.com/mripard/xf86-video-armsoc
cd xf86-video-armsoc
./autogen.sh
make -j5
make install
cp /usr/local/lib/xorg/modules/drivers/* /usr/lib/xorg/modules/drivers/
cp xorg.conf /etc/X11/
cd ..
git clone https://github.com/free-electrons/mali-blobs.git
cd mali-blobs
cp -a r6p2/x11_dma_buf/lib_x11_dma_buf/ /usr/lib

The commit (nextthingco/linux@e390023) already existed in my kernel.

Load the module
insmod /lib/modules/4.14.18-sunxi/extra/mali.ko
Run startx and run glxgears:

[giuliobenetti]

Try to follow #23 issue.
There they make it working, then there is a branch to test because it goes slow even with sun4i-armsoc.so installed correctly.
Try with master branch if everything works ok,
if yes, go on commenting on that issue.

I think you can close this, since topic is changed. Thanks!
