That sounds an awful lot like the Android kernel's pmem implementation. Solving this problem is important for us as well, but, I'm not sure I see a better solution that something like Felipe suggests. The disadvantage, of course, being that the memory isn't available for the system when the user isn't doing the multi-media. David -- Sent by an employee of the Qualcomm Innovation Center, Inc.
