For every 1MB of DSP Virtual address 1Kbytes of physical memory is required for house keeping. So, for 256MB we would be taking 256K as opposed to 64K when using 64MB DSP virtual memory. The requirement comes more from Multimedia requirements, and with all the new phones having the requirement of running multiple multimedia applications in parallel 256K would be safe.

It will. Increasing DMM pool size doesn't have any dependency on shm size. The SHM is used for IPC mechanism to exchange data and loading base images. The DMM is just the DSP virtual address pool that is used for dynamic memory mapping to the buffers allocated on ARM (this buffer is not coming from SHM).
