Simultaneous read access of DMA buffers is leading to "bus error"

Apoorva Nagarajan

Hi,

I am using GLSDK 6.04. I am trying to build an application based on the encoder. I am using the omap drmif APIs for buffer allocation (libdrm/omap/omap_drmif.h). Simultaneous read access of these buffers from two different threads is leading to a "bus error" crash. Any help regarding why this would happen or how to access these buffers simultaneously would be appreciated. 

Regards,

Apoorva
