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?
Hi Iscandolo,
1) Could you please confirm that you have built GATOR using following settings:
GATOR_WITH_MALI_SUPPORT=MALI_400 KCFLAGS=\"-I/path/to/ddk/source -DGATOR_MALI_INTERFACE_STYLE=3 -DGATOR_TEST_ENABLED -DxxDEBUG\" make -j8 -C /path/to/linux/kernel M=`pwd` ARCH=arm CROSS_COMPILE=arm-eabi- modules"
2) Are you getting warnings about any other missing symbols or just the one about _mali_osk_fb_control_set ?
