Driver compile with profiling option

Hello!

I am trying to use Mali GPU performance analyzer.

At first, I thought that performance analyzer can be connected to target embedded device by installing "libmaliinstr.so" library file to target embedded platform.

But it didn't work.

In user guide, there is a requirement that an instrumented driver should be used for profiling.

Does it mean Mali Linux kernel device driver should be compiled with profiling option? (USING_PROFILING in Makefile)

When I try this, I get error messages.

FIrst,  mali_cinstr_profiling_events_m200.h header file doesn't exist , it is included by mali_kernel_profiling.h

And some undeclared define values make problem

drivers/media/video/samsung/mali/common/mali_kernel_MALI200.c:646: error: 'MALI_PROFILING_EVENT_TYPE_START' undeclared (first use in this function)

drivers/media/video/samsung/mali/common/mali_kernel_MALI200.c:718: error: 'MALI_PROFILING_EVENT_TYPE_STOP' undeclared (first use in this function)

    Hi KarthikH

    I am just trying to use performance analyzer for research purpose.

    It's frustrating if we need to  require the instrumented driver from Samsung (We are using exynos  4210 SoC)

    It's nearly impossible.

    We only need to get FPS(Frame Per Second) while a target graphic application is running.

    Is there any way we can get FPS without performance analyzer ?
