6 bool "Enable the Anonymous Shared Memory Subsystem"
10 The ashmem subsystem is a new shared memory allocator, similar to
11 POSIX SHM but with different behavior and sporting a simpler
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.
17 config ANDROID_LOW_MEMORY_KILLER
18 bool "Android Low Memory Killer"
20 Registers processes to be killed when low memory conditions, this is useful
21 as there is no particular swap space on android.
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
28 bool "Synchronization framework"
31 select DMA_SHARED_BUFFER
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.
38 bool "Software synchronization objects"
43 A sync object driver that uses a 32bit counter to coordinate
44 synchronization. Useful when there is no hardware primitive backing
