Dynamic loading of Overlays in 5.0.y

martinayotte · March 13, 2019

I've done a discovery : when using current Armbian overlays in 5.0.y thru dynamic loading (aka : /sys/kernel/config/devices-tree/overlays) , although working, it produced the following warning in "dmesg" :

WARNING: memory leak will occur if overlay removed

Example, loading i2c overlays produce :

[   80.494728] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /aliases/i2c0
[   80.494745] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /aliases/i2c1
[   80.494752] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /aliases/i2c2
[   80.494789] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/i2c@1c2ac00/status
[   80.494798] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/i2c@1c2b000/clock-frequency
[   80.494805] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/i2c@1c2b000/status
[   80.494813] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/i2c@1c2b400/status

Googling reveal those links, it is all about overlays refactoring :

https://lkml.org/lkml/2018/10/5/146

https://elinux.org/images/8/86/Overlay_frank.pdf

So, we will have to upgrade those overlays when we get a change ... :unsure:

Hmmm so temporarily not dynamic

@martinayotte

Have you started pushing the 5.x stuff up to master yet or would you be willing to work out of a branch from sunxi kernel 5 until its stable?

Might make it easier to divide and conquer on the different surprises

Werner · March 14, 2019

4.20 has been archvied https://github.com/armbian/build/releases/tag/sunxi-4.20 so I assume 5.0 can be pushed directly to master. And if it breaks does not matter as it is dev.

martinayotte · March 14, 2019

I've done several local builds with success, although some patches are still failing, they don't prevent doing a build.

I will push preliminary stuff soon ...

Fair enough. I know the branch conversation has happened more than once on the forum, and generally the added complexity hasnt been appealing.

I suppose viewing armbian as a rolling release and embracing next as "mainline stable" supports the model?

I've committed the initial stuff ! :rolleyes:

Now, I will pursue the patch cleaning ...

Let me know if you are unable to build 5.0.y on some Allwinner boards ...

Similar failure with H5 OpiPC2. Seems to be building for H3 OpiLite okay.

Uhh so i installed mate desktop...and other than stuck with a 1024x768 modeline... the display driver is crazy fast!

Werner · March 15, 2019

Awesome.

I'll give the OPi1+ a shot on dev as well soon.

NanoPi Neo2 (non-LTS) also running here with Kernel 5.0.1
i2c0-overlay doesnt show a memory-leak in dmesg

~~UTF8-charset doesnt seem to work right (lines around the menu) while using de-utf8~~

[EDIT] also doesnt work on one of my Neo2 with 4.20.7-sunxi64, but one does show it right.
and I copied the putty-session-settings...so putty shouldnt be the problem

The memory-leak issue is not when overlays are loaded by U-boot, but only when loaded dynamically using Overlay-FS, aka via /sys/kernel/config/device-tree/overlays/ from userspace, for example :

mkdir /sys/kernel/config/device-tree/overlays/myoverlay
cat myoverlay.dtbo > /sys/kernel/config/device-tree/overlays/myoverlay/dtbo
cat /sys/kernel/config/device-tree/overlays/myoverlay/status

OK, I was thinking about the (dynamic) i2c0 overlay from armbian-config --> /boot/armbianEnv.txt

Right ! Those are Ok !

That one of the reason there is no hurry to fix memory-leak issue, since I'm probably the only one who is using "dynamic" userspace method ... :lol:
