Dear all,

I'm trying to build linux Mali200 driver in arm system.
I build mali.ko and insert it success in linux.
The attachment is log when I insert module.
It always told me "Mali device driver r2p2-03rel0 loaded".

Would you please tell me how could I make sure the driver work success?
Because I try to run the SimpleProject.
It always get the error message "Error: No EGL Display available at src/egl_runtime.c:64"

thanks.

    Hi Larry,

    The Mali Driver comes in 2 parts, kernel side and userspace side.

    The kernel side is under GPL and freely available to download from our website, as you have already found.

    However the userspace side is proprietary. We do not give the sources publicly to this.

    It is expected that you get your Mali driver from the SoC vendor. In this instance it would be Samsung.

    However please note that a lot of development board companies also provide BSPs with working Mali driver binaries integrated.

    For example, if you were using the HardKernel ODROID X (which has the Exynos 4412), you would obtain the userspace Mali driver from HardKernel.

    I hope that helps clarify things for you.

    Kind Regards
