[Q] How can I upgrade Mali device driver?


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

Linux kernel : 3.0.31
Processor : exynos4210
Target Mali driver version: 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
