| |
For example: Before: $ perf record -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -- ls -l Error: branch-loads: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat' After: $ perf record -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -- ls -l Error: branch-loads: PMU Hardware doesn't support 'aux_output' feature
