How can I upgrade Mali device driver?

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
