Each event details +are stored into separate text file. Once perf command is finished +these files are checked for values we expect for command. + +The attr tests consist of following parts: + +tests/attr.c +------------ +This is the sys_perf_event_open hook implementation. The hook +is triggered when the PERF_TEST_ATTR environment variable is +defined. It must contain name of existing directory with access +and write permissions. + +For each sys_perf_event_open call event details are stored in +separate file. Besides 'struct perf_event_attr' values we also +store 'fd' and 'group_fd' values to allow checking for groups. + +tests/attr.py +------------- +This is the python script that does all the hard work. It reads +the test definition, executes it and checks results. + +tests/attr/ +----------- +Directory containing all attr test definitions. +Following tests are defined (with perf commands): + + perf
