How can I upgrade Mali device driver?

azure

Hi,

I'm trying to upgrade Mali driver on my I9220.

Linux kernel : 3.0.31

Processor : exynos4210

Mali driver version: r2p4

i want to upgrade Mali driver to r3p1

I only replaced Mali driver in the kernel .

And I could get linux kernel image successfully. (Mali driver is built -in form.)

I turned on my board and saw all black screen.

I also checked memory address in config.h file.

I only saw booting screen then the screen was changed in black..

is there any other driver should I replace? such as gralloc driver...

I have a one more thing..

I want to use streamline for Mali profiling.

What version of linux kernel and Mali driver was verified for gpu profiling?

Or should I change something in my setting?

I am so ignorant about this.

Kindly let me know.

or tell me which phone can use to Mali profiling with streamline

Thank you

    Hi zhong,

    r3p1 should be fine for Streamline profiling, but I believe you will also need to acquire r3p1 userspace binaries (libEGL.so, libGLESv2.so etc), to match the kernel drivers you have integrated. These at present can only be acquired from the vendor themselves, Samsung in this case.

    Thanks,

    Chris
