Hi,
I have a few questions with regards to alloc'ing and locking down memory. An example would be very useful. Please CC me on any responses.
1. Is there a mechanism to lock down large amounts of memory (>128M, upto 256M). Can 256M be allocated using vmalloc, if so is it swappable? 2. Is it possible for a user process and kernel to access the same shared memory? 3. Can a shared memory have visibility across processes, i.e. can process A access memory that was allocated by process B? 4. When a process exits will it cause a close to occur on the device?
Thanks, Bhavana
