| ---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. | |

| 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. | |

| ---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. | |
