With AMD Ryzen processor it doesn't compiles with the error: In file included from arch/x86/events/core.c:44: arch/x86/events/perf_event.h:1033:45: warning: ‘struct cpu_hw_event’ declared inside parameter list will not be visible outside of this definition or declaration static inline int intel_cpuc_prepare(struct cpu_hw_event *cpuc, int cpu) ^~~~~~~~~~~~ arch/x86/events/perf_event.h:1038:45: warning: ‘struct cpu_hw_event’ declared inside parameter list will not be visible outside of this definition or declaration static inline void intel_cpuc_finish(struct cpu_hw_event *cpuc) ^~~~~~~~~~~~ CC lib/errseq.o arch/x86/events/core.c: In function ‘free_fake_cpuc’: arch/x86/events/core.c:1973:20: error: passing argument 1 of ‘intel_cpuc_finish’ from incompatible pointer type [-Werror=incompatible-pointer-types] intel_cpuc_finish(cpuc); ^~~~ In file included from arch/x86/events/core.c:44: arch/x86/events/perf_event.h:1038:59: note: expected ‘struct cpu_hw_event *’ but argument is of type ‘struct cpu_hw_events *’ static inline void intel_cpuc_finish(struct cpu_hw_event *cpuc) ~~~~~~~~~~~~~~~~~~~~~^~~~ arch/x86/events/core.c: In function ‘allocate_fake_cpuc’: arch/x86/events/core.c:1987:25: error: passing argument 1 of ‘intel_cpuc_prepare’ from incompatible pointer type [-Werror=incompatible-pointer-types] if (intel_cpuc_prepare(cpuc, cpu)) ^~~~ In file included from arch/x86/events/core.c:44: arch/x86/events/perf_event.h:1033:59: note: expected ‘struct cpu_hw_event *’ but argument is of type ‘struct cpu_hw_events *’ static inline int intel_cpuc_prepare(struct cpu_hw_event *cpuc, int cpu) I found this bug report in kernel linux bugzilla and it seems to be related: https://bugzilla.kernel.org/show_bug.cgi?id=202917 I already compile without any problem this kernel version in Intel Broadwell-u processor.
