Hi,
If you compile tip.git on ARM32 (or ARM64, I bet) you compile link time errors:
libperf.a(libperf-in.o): In function `intel_pt_synth_branch_sample': /home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:899: undefined reference to `tsc_to_perf_time' libperf.a(libperf-in.o): In function `intel_pt_synth_transaction_sample': /home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:992: undefined reference to `tsc_to_perf_time' libperf.a(libperf-in.o): In function `intel_pt_synth_instruction_sample': /home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:943: undefined reference to `tsc_to_perf_time' libperf.a(libperf-in.o): In function `intel_pt_process_event': /home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:1484: undefined reference to `perf_time_to_tsc' libperf.a(libperf-in.o): In function `intel_pt_process_itrace_start': /home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:1455: undefined reference to `perf_time_to_tsc' libperf.a(libperf-in.o): In function `intel_pt_process_switch': /home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:1405: undefined reference to `perf_time_to_tsc' /home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:1427: undefined reference to `perf_time_to_tsc' libperf.a(libperf-in.o): In function `intel_bts_process_event': /home/ubuntu/perfmon/linux/tools/perf/util/intel-bts.c:614: undefined reference to `perf_time_to_tsc'
That's because if AUXTRACE is detected, it pulls in x86 specific stuff like intel-pt. This should be decoupled.
