+config ASHMEM
+       bool "Enable the Anonymous Shared Memory Subsystem"
+       default n
+       depends on SHMEM
+       ---help---
+         The ashmem subsystem is a new shared memory allocator, similar to
+         POSIX SHM but with different behavior and sporting a simpler
+         file-based API.
+
+         It is, in theory, a good memory allocator for low-memory devices,
+         because it can discard shared memory units when under memory pressure.

+       ---help---
+         This option enables the framework for synchronization between multiple
+         drivers.  Sync implementations can take advantage of hardware
+         synchronization built into devices like GPUs.
+
+config SW_SYNC
+       bool "Software synchronization objects"
+       default n
+       depends on SYNC
+       ---help---
+         A sync object driver that uses a 32bit counter to coordinate
+         syncrhronization.  Useful when there is no hardware primitive backing
+         the synchronization.
+
+config SW_SYNC_USER
+       bool "Userspace API for SW_SYNC"
+       default n
+       depends on SW_SYNC
+       ---help---
+         Provides a user space API to the sw sync object.
+         *WARNING* improper use of this can result in deadlocking kernel
+         drivers from userspace.
