Debugging Mali driver in 3.4 kernel in Origen

Hello

I am trying to make ICS Android (Mali) work in Origen with 3.4 kernel

Now  as using Mali driver, gralloc_ump r2p4-02rel in 3.4 kernel with the following Android branch.
repo init -u git://android.git.linaro.org/platform/manifest.git -b linaro_android_4.0.4 -m tracking-origen.xml

I have the following errors:

*******************************************************************************
[   15.225000] MALI PHYSICAL RANGE VALIDATION ERROR!
[   15.235000] We failed to validate a Mali-Physical range that the user-side wished to map in
[   15.245000] It is likely that the user-side wished to do Direct Rendering, but a suitable
[   15.250000] address range validation mechanism has not been correctly setup
[   15.260000] The range supplied was: phys_base=0x6D900000, size=0x004B0000
[   15.270000] Please refer to the ARM Mali Software Integration Guide for more information.
[   15.275000] *******************************************************************************

In my opinion, it seems that user space library call ioctl command with in-proper argument. 
    ioctl command (MALI_IOC_MEM_MAP_EXT)  with the wrong params: phys_base=0x6D900000, size=0x004B0000

In addition, currently I didn't  add UMP remap call  in  Framebuffer drivers.  Is it possible reason ?


Thanks

    Is the GPU powered up?

    If you poke a register using a debugger what happens? If that hangs check you have turned it on before you poke it.

    Your advice is correct.
    When Mali was running, other driver mistakenly believed that it could turn off Mali's power
    because  the power to Mali was not used by anyone.
