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 50config ANDROID_BINDER_ALLOC_KUNIT_TEST 51 tristate "KUnit Tests for Android Binder Alloc" if !KUNIT_ALL_TESTS 52 depends on ANDROID_BINDER_IPC && KUNIT 53 default KUNIT_ALL_TESTS 54 help 55 This feature builds the binder alloc KUnit tests. 56 57 Each test case runs using a pared-down binder_alloc struct and 58 test-specific freelist, which allows this KUnit module to be loaded 59 for testing without interfering with a running system. 60 61endmenu 62
