Hi,

Is there any size limit for buffers used for fastrpc buffer sharing between the CPU and Hexagon DSP ? And is there any way to overcome this size limit by changing the driver/kernel/runtime etc ?
 

For large sized allocations, the memory allocator successfully allocates memory but the buffers are not updated properly. For eg values written by the DSP are not visible in the CPU side. (If these buffers were small then the buffer updates happen properly)

I am using Hexagon SDK 1.1.0 and android 4.3 runs on the APQ8074 dragon board.
