full event names\n\nThis patch changes the way perf stat prints event names at the end of a\nrun. Until now, it was trying to reconstruct the event name from its\nencoding. The problem is that it would only print generic events without\ntheir modifiers (u, k, pp).\n\nThis patch saves the event name as passed by the user in the evsel\nstruct and uses it to print the final event name.\n\nThis would also work in case perf is linked with a library (such as\nlibpfm4) which provides full PMU event tables.\n\n$ perf stat -e cycles:u,cycles:k date\nWed Feb 16 14:58:52 CET 2011\n\n Performance counter stats for \u0027date\u0027:\n\n 568600 cycles:u\n 2779715 cycles:k\n\n 0.001908182 seconds time elapsed\n\nCc: Arun Sharma \u003carun@sharma-home.net\u003e\nCc: David S.

for the case where the workload is started\nfrom \u0027perf record\u0027, as -1 is the default for target_tid in \u0027perf record --tid\u0027\nparameter, so somehow we were trying to synthesize the PERF_RECORD_MMAP and\nPERF_RECORD_COMM events for the thread -1, a bug.\n\nSo I investigated this and noticed that when we introduced support for\nrecording a process and its threads using --pid some bugs were introduced and\nthat the way to fix it was to instead of passing the target_tid to the event\nsynthesizing routines we should better pass the thread_map that has the list of\nthreads for a --pid or just the single thread for a --tid.\n\nChecked in the following ways:\n\nOn a 8-way machine run cyclictest:\n\n[root@emilia ~]# perf record cyclictest -a -t -n -p99 -i100 -d50\npolicy: fifo:
