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.
config ANDROID_TIMED_OUTPUT
bool "Timed output class driver"
default y
config ANDROID_TIMED_GPIO
tristate "Android timed gpio driver"
depends on GPIOLIB && ANDROID_TIMED_OUTPUT
default n
config ANDROID_LOW_MEMORY_KILLER
bool "Android Low Memory Killer"
---help---
Registers processes to be killed when memory is low
config SYNC
bool "Synchronization framework"
default n
select ANON_INODES
---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.
