| 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. |

| Detect oom_adj values written to |

| ---help--- |
| This option adds support for the Virtual SoC driver needed to boot |
| a 'cuttlefish' Android image inside QEmu. The driver interacts with |
| a QEmu ivshmem device. If built as a module, it will be called vsoc. |
