[Buildroot] sun8i-h3: sunxi-mali-mainline package with linux-next

[Buildroot] sun8i-h3: sunxi-mali-mainline package with linux-next

[Jagan Teki]

Hi,

I'm trying to use sunxi-mali-mainline with linux-next for H3 platform.

Since Mali dt support is already added on linux-next, So I've directly
used buildroot and enabled necessary options.

Look like Mali initialization seems failing. I've not investigated
further but just to post if anyone found this already and seeking for
help.

Log:

I would suggest you to use master branch or at least 4.17 version 
instead of linux-next.
But I'm not sure this is the root-cause.
Maybe give it a try if you can.

IMHO this is very specific to driver more than buildroot package and
I suggest you to open an issue on https://github.com/mripard/sunxi-mali
So everything dealing with driver is treated there and maybe it's a 
better place to find help and keep trace for the others
(hope it's the right way, this is my first package maintained in 
Buildroot, so I don't know if I'm doing good, please let me know Peter, 
Maxime, Thomas and others, thanks).

Kind regards
Giulio

Driver is loaded automatically on boot,
since during install it is added to /lib/modules/extras
Are you sure you're not trying to modprobe twice?
Can you post lsmod before modprobe?
It should be already loaded.

If it's already loaded and not working can you post your dmesg?

Thanks

Kind regards

Yes, I agree. The sunxi-mali project is the best place to discuss these
things if they are not directly related to the Buildroot packaging. If a
fix is found, then the version in Buildroot should naturally be bumped.

Ok, so on Buildroot side it's ok.
I ask you to open an issue on https://github.com/mripard/sunxi-mali

Thanks
