Hi Rob
Userspace counter access only works on heterogeneous systems with some restrictions. The userspace process must be pinned to a homogeneous subset of CPUs and must open the corresponding PMU for those CPUs. This commit adds a test implementing these requirements.
Are you planning to change x86 tests (tools/perf/arch/x86/tests/rdpmc.c) to use libperf as well? Best Regards Shunsuke _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
