hello

I am trying to install mali drivers (32 bits) from
https://bootlin.com/blog/mali-opengl-support-on-allwinner-platforms-with-mainline-linux/

after following the tutorial, i have this error

Error applying patch

any helps would be great and appreciate it :)
thanks :)

You have to install 'quilt' on your distro.
i.e. On Ubuntu/debian-like:

sudo apt install quilt

then reissue:

./build.sh -r r6p2 -b

It should build correctly now.

thanks for your quick reply :)

i made install and this is the result

Error building the driver

for precision, i am on 4.14 kernel

thanks for your help :)

You should follow instructions in sunxi-mali driver:
https://github.com/mripard/sunxi-mali

You will find README.md that explains step-by-step how to build and install correctly.
As written in your log, KDIR variable is not found and here https://github.com/mripard/sunxi-mali/blob/master/README.md you find:
export KDIR=$KERNEL_BUILD_DIR

Anyway it's easier if you follow those few steps.

Best regards

thanks for your response and really appreciate your help :)
i am currently reading the step by step from link

hope i will find myself about export KDIR=$KERNEL_BUILD_DIR

on any case, i will update my progress :)
thanks again for your time and help :)

Best regards.
