This optimization avoids logging having too 50 much overhead in the system. 51 52config ANDROID_TIMED_OUTPUT 53 bool "Timed output class driver" 54 default y 55 56config ANDROID_TIMED_GPIO 57 tristate "Android timed gpio driver" 58 depends on GPIOLIB && ANDROID_TIMED_OUTPUT 59 default n 60 61config ANDROID_LOW_MEMORY_KILLER 62 bool "Android Low Memory Killer" 63 default N 64 ---help--- 65 Registers processes to be killed when memory is low 66 67config ANDROID_INTF_ALARM_DEV 68 bool "Android alarm driver" 69 depends on RTC_CLASS 70 default n 71 ---help--- 72 Provides non-wakeup and rtc backed wakeup alarms based on rtc or 73 elapsed realtime, and a non-wakeup alarm on the monotonic clock. 74 Also exports the alarm interface to user-space. 75 76config SYNC 77 bool "Synchronization framework" 78 default n 79 select ANON_INODES 80 help 81 This option enables the framework for synchronization between multiple 82 drivers. Sync implementations can take advantage of hardware 83 synchronization built into devices like GPUs. 84 85config SW_SYNC 86 bool "Software synchronization objects" 87 default n 88 depends on SYNC 89 help 90 A sync object driver that uses a 32bit counter to coordinate 91 syncrhronization. Useful when there is no hardware primitive backing 92 the synchronization. 93 94config SW_SYNC_USER 95 bool "Userspace API for SW_SYNC" 96 default n 97 depends on SW_SYNC 98 help 99 Provides a user space API to the sw sync object. 100 *WARNING* improper use of this can result in deadlocking kernel 101 drivers from userspace. 102 103endif # if ANDROID 104 105endmenu 106
