![]() This patch adds support for profiling JIT generated code to 'perf report'. A JIT compiler is required to generate a "/tmp/perf-$PID.map" symbols map that is parsed when looking and displaying symbols. Thanks to Peter Zijlstra for his help with this patch! Example "perf report" output with the Jato JIT: # # (40311 samples) # # Overhead Command Shared Object Symbol # ........ ................ ......................... ...... # 97.80% jato /tmp/perf-11915.map [.] Fibonacci.fib(I)I 0.56% jato 00000000b7fa023b 0x000000b7fa023b 0.45% jato /tmp/perf-11915.map [.] Fibonacci.main([Ljava/lang/String;)V 0.38% jato [kernel] [k] get_page_from_freelist 0.06% jato [kernel] [k] kunmap_atomic 0.05% jato ./jato [.] utf8Hash 0.04% jato ./jato [.] executeJava 0.04% jato ./jato [.] defineClass Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi> Cc: a.p.zijlstra@chello.nl Cc: acme@redhat.com LKML-Reference: <Pine.LNX.4.64.0906082111590.12407@melkki.cs.Helsinki.FI> Signed-off-by: Ingo Molnar <mingo@elte.hu> |
