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_LOW_MEMORY_KILLER
bool "Android Low Memory Killer"
---help---
Registers processes to be killed when low memory conditions, this is useful
as there is no particular swap space on android.
The registered process will kill according to the priorities in android init
scripts (/init.rc), and it defines priority values with minimum free memory size
for each priority.
config SW_SYNC
bool "Software synchronization framework"
default n
depends on SYNC_FILE
depends on DEBUG_FS
---help---
A sync object driver that uses a 32bit counter to coordinate
synchronization. Useful when there is no hardware primitive backing
the synchronization.
WARNING: improper use of this can result in deadlocking kernel
drivers from userspace. Intended for test and debug only.
