  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.

 36         ---help---
 37           This option enables the framework for synchronization between multiple
 38           drivers.  Sync implementations can take advantage of hardware
 39           synchronization built into devices like GPUs.

 45         ---help---
 46           A sync object driver that uses a 32bit counter to coordinate
 47           syncrhronization.  Useful when there is no hardware primitive backing
 48           the synchronization.

 50 config SW_SYNC_USER
 51         bool "Userspace API for SW_SYNC"
 52         default n

 54         ---help---
 55           Provides a user space API to the sw sync object.
 56           *WARNING* improper use of this can result in deadlocking kernel
 57           drivers from userspace.
