Each binder device has its own context manager, and is 38 therefore logically separated from the other devices. 39 40config ANDROID_BINDER_IPC_SELFTEST 41 bool "Android Binder IPC Driver Selftest" 42 depends on ANDROID_BINDER_IPC 43 help 44 This feature allows binder selftest to run. 45 46 Binder selftest checks the allocation and free of binder buffers 47 exhaustively with combinations of various buffer sizes and 48 alignments. 49 50endmenu 51
