This optimization avoids logging having too 49 much overhead in the system. 50 51config ANDROID_TIMED_OUTPUT 52 bool "Timed output class driver" 53 default y 54 55config ANDROID_TIMED_GPIO 56 tristate "Android timed gpio driver" 57 depends on GENERIC_GPIO && ANDROID_TIMED_OUTPUT 58 default n 59 60config ANDROID_LOW_MEMORY_KILLER 61 bool "Android Low Memory Killer" 62 default N 63 ---help--- 64 Registers processes to be killed when memory is low 65 66config ANDROID_INTF_ALARM_DEV 67 bool "Android alarm driver" 68 depends on RTC_CLASS 69 default n 70 ---help--- 71 Provides non-wakeup and rtc backed wakeup alarms based on rtc or 72 elapsed realtime, and a non-wakeup alarm on the monotonic clock. 73 Also exports the alarm interface to user-space. 74 75config SYNC 76 bool "Synchronization framework" 77 default n 78 select ANON_INODES 79 help 80 This option enables the framework for synchronization between multiple 81 drivers. Sync implementations can take advantage of hardware 82 synchronization built into devices like GPUs. 83 84config SW_SYNC 85 bool "Software synchronization objects" 86 default n 87 depends on SYNC 88 help 89 A sync object driver that uses a 32bit counter to coordinate 90 syncrhronization. Useful when there is no hardware primitive backing 91 the synchronization. 92 93config SW_SYNC_USER 94 bool "Userspace API for SW_SYNC" 95 default n 96 depends on SW_SYNC 97 help 98 Provides a user space API to the sw sync object. 99 *WARNING* improper use of this can result in deadlocking kernel 100 drivers from userspace. 101 102endif # if ANDROID 103 104endmenu 105
