menu "Android" config ANDROID bool "Android Drivers" default N ---help--- Enable support for various drivers needed on the Android platform if ANDROID config ANDROID_BINDER_IPC bool "Android Binder IPC Driver" default n ---help--- Binder is used in Android for both communication between processes, and remote method invocation. This means one Android process can call a method/routine in another Android process, using Binder to identify, invoke and pass arguments between said processes. 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_LOGGER tristate "Android log driver" 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_TIMED_OUTPUT bool "Timed output class driver" default y config ANDROID_TIMED_GPIO tristate "Android timed gpio driver" depends on GPIOLIB && ANDROID_TIMED_OUTPUT default n config ANDROID_LOW_MEMORY_KILLER bool "Android Low Memory Killer" default N ---help--- Registers processes to be killed when memory is low config ANDROID_INTF_ALARM_DEV bool "Android alarm driver" depends on RTC_CLASS default n ---help--- Provides non-wakeup and rtc backed wakeup alarms based on rtc or elapsed realtime, and a non-wakeup alarm on the monotonic clock. Also exports the alarm interface to user-space. config SYNC bool "Synchronization framework" default n select ANON_INODES 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 help A sync object driver that uses a 32bit counter to coordinate syncrhronization. Useful when there is no hardware primitive backing the synchronization. config SW_SYNC_USER bool "Userspace API for SW_SYNC" default n depends on SW_SYNC help Provides a user space API to the sw sync object. *WARNING* improper use of this can result in deadlocking kernel drivers from userspace. endif # if ANDROID endmenu
