Ok, so I tried installing the Broadwell ones (one of my test machines) and got into:
[root@jouet ~]# perf stat -M Pipeline flops bpf: builtin compilation failed: -95, try external compiler ERROR: problems with path cpu/uops_executed.c: No such file or directory Cannot set up events {uops_retired.retire_slots,inst_retired.any}:W,{inst_retired.any,cycles}:W,{uops_executed.thread,cpu/uops_executed.core,cmask=1/,uops_executed.cycles_ge_1_uop_exec}:W
Usage: perf stat [<options>] [<command>]
-M, --metrics <metric/metric group list> monitor specified metrics or metric groups (separated by ,) [root@jouet ~]# perf stat -M Pipeline flops
Wasn't this already fixed?
This is with these patches applied:

Will try with all of them...
