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 record kill (test-record-basic) - perf record -b kill (test-record-branch-any) - perf record -j any kill (test-record-branch-filter-any) - perf record -j any_call kill (test-record-branch-filter-any_call) - perf record -j any_ret kill (test-record-branch-filter-any_ret) - perf record -j hv kill (test-record-branch-filter-hv) - perf record -j ind_call kill (test-record-branch-filter-ind_call) - perf record -j k kill (test-record-branch-filter-k) - perf record -j u kill (test-record-branch-filter-u) - perf record -c 123 kill (test-record-count) - perf record -d kill (test-record-data) - perf record -F 100 kill (test-record-freq) - perf record -g kill (test-record-graph-default) - perf record -g kill (test-record-graph-default-aarch64) - perf record --call-graph dwarf kill (test-record-graph-dwarf) - perf record --call-graph fp kill (test-record-graph-fp) - perf record --call-graph fp kill (test-record-graph-fp-aarch64) - perf record -e '{cycles,instructions}' kill (test-record-group1) - perf record -e '{cycles/period=1/,instructions/period=2/}:S' kill (test-record-group2) - perf record -D kill (test-record-no-delay) - perf record -i kill (test-record-no-inherit) - perf record -n kill (test-record-no-samples) - perf record -c 100 -P kill (test-record-period) - perf record -c 1 --pfm-events=cycles:period=2 (test-record-pfm-period) - perf record -R kill (test-record-raw) - perf record -c 2 -e arm_spe_0// -- kill (test-record-spe-period) - perf record -e arm_spe_0/period=3/ -- kill (test-record-spe-period-term) - perf record -e arm_spe_0/pa_enable=1/ -- kill (test-record-spe-physical-address) - perf stat -e cycles kill (test-stat-basic) - perf stat kill (test-stat-default) - perf stat -d kill (test-stat-detailed-1) - perf stat -dd kill (test-stat-detailed-2) - perf stat -ddd kill (test-stat-detailed-3) - perf stat -e '{cycles,instructions}' kill (test-stat-group1) - perf stat -i -e cycles kill (test-stat-no-inherit) |
