menu "Android" if ANDROID 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 SYNC bool "Synchronization framework" default n select ANON_INODES select DMA_SHARED_BUFFER ---help--- This option enables the framework for synchronization between multiple drivers. Sync implementations can take advantage of hardware synchronization built into devices like GPUs. config SW_SYNC bool "Software synchronization objects" default n depends on SYNC depends on SYNC_FILE ---help--- A sync object driver that uses a 32bit counter to coordinate synchronization. Useful when there is no hardware primitive backing the synchronization. source "drivers/staging/android/ion/Kconfig" endif # if ANDROID endmenu
