Mali-400 Driver r1p1 rel1 incompatible with GATOR

Leonardo Scandolo

Note: This was originally posted on 27th August 2013 at http://forums.arm.com

I am trying to get profiling information from a Mali-400 in configuration with an A13, using driver r1p1 release 1 for the Mali-400. Whenever I run GATOR, it checks for the callback called *_mali_osk_fbcontrol_set*, but it is nowhere to be found in the Mali-400 driver code, so it cannot retrieve profiling information from the GPU. Has anyone run into this problem? Is that callback available in other drivers, or do I need to get any missing modules ?


The error message I get while trying to capture gator information is "gator: mali online _mali_osk_fbcontrol_set symbol not found". While running the ds-5, it says the configuration is incompatible when trying to check any variables related to the Mali-400, but everything else (CPU, Mem) works flawlessly.


Any ideas?

    Hello Iscandolo,

    Can you please confirm the driver version?
    r1p1 is a very very old version of the driver, however is the latest revision of the hardware.
    Do you mean that you are using r1p1 hardware? If this is correct, can you provide the version of your driver in addition to this?
    This can most easily be checked by running strings on the mali.so library, and searching for the word REVISION.

    Thanks in advance,
