| * perf trace: Fix summary percentage when processing filesDavid Ahern2013-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Getting a divide by 0 when events are processed from a file: perf trace -i perf.data -s ... dnsmasq (1684), 10 events, inf%, 0.000 msec The problem is that the event count is not incremented as events are processed. With this patch: perf trace -i perf.data -s ... dnsmasq (1684), 10 events, 8.9%, 0.000 msec Signed-off-by: David Ahern <dsahern@gmail.com> Link: http://lkml.kernel.org/r/1386211302-31303-4-git-send-email-dsahern@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
| * perf trace: Add support for syscalls vs raw_syscallsDavid Ahern2013-12-05
| | | | | | | | | | | | | | | | | | | | Older kernels (e.g., RHEL6) do system call tracing via syscalls:sys_{enter,exit} rather than raw_syscalls. Update perf-trace to detect lack of raw_syscalls support and try syscalls.

* perf tools: Add trace-event global object for tracepoint interfaceJiri Olsa2013-12-04
| | | | | | | | | | | | | | | | | | | | | | | | In order to get the proper plugins processing we need to use full trace-event interface when creating tracepoint events. So far we were using shortcut to get the parsed format. Moving current 'event_format__new' function into trace-event object as 'trace_event__tp_format'. This function uses properly initialized global trace-event object, ensuring proper plugins processing.

| | | | | | | | | | | | | | | | | | | | | | | | | | The logic was not looking in the buildid cache for kcore if the host kernel buildid did not match the recorded kernel buildid. This affects the non-live case i.e. the kernel has changed and we are looking at a special copy of kcore that we placed in the buildid cache (using "perf buildid-cache -v -k /proc/kcore") when the data was recorded. After this fix kernel symbols get resolved/annotated correctly.
