| 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_LOGGER |

| default n |
| ---help--- |
| This adds support for system-wide logging using four log buffers. |
| |
| These are: |
| |
| 1: main |
| 2: events |
| 3: radio |
| 4: system |
| |
| Log reading and writing is performed via normal Linux reads and |
| optimized writes. This optimization avoids logging having too |
| much overhead in the system. |
| |
| 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. |
