  9         ---help---
 10           The ashmem subsystem is a new shared memory allocator, similar to
 11           POSIX SHM but with different behavior and sporting a simpler
 12           file-based API.
 13 
 14           It is, in theory, a good memory allocator for low-memory devices,
 15           because it can discard shared memory units when under memory pressure.

 19         ---help---
 20           Registers processes to be killed when low memory conditions, this is useful
 21           as there is no particular swap space on android.
 22 
 23           The registered process will kill according to the priorities in android init
 24           scripts (/init.rc), and it defines priority values with minimum free memory size
 25           for each priority.

 32         ---help---
 33           This option enables the framework for synchronization between multiple
 34           drivers.  Sync implementations can take advantage of hardware
 35           synchronization built into devices like GPUs.

 42         ---help---
 43           A sync object driver that uses a 32bit counter to coordinate
 44           synchronization.  Useful when there is no hardware primitive backing
 45           the synchronization.
