perf tools: Handle kernels that don't support attr.exclude_{guest,host}

2012-03-03T15:19:56Z

Just fall back to resetting those fields, if set, warning the user that that feature is not available. If guest samples appear they will just be discarded because no struct machine will be found and thus the event will be accounted as not handled and dropped, see 0c09571.

perf top: Stop using globals for tool state

2011-11-28T12:39:44Z

Use its 'perf_tool' base class instead. Cc: David Ahern Cc: Frederic Weisbecker Cc: Mike Galbraith Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-i33q40wwvk2zna8fd36ex6sm@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Rename perf_event_ops to perf_tool

2011-11-28T12:39:28Z

To better reflect that it became the base class for all tools, that must be in each tool struct and where common stuff will be put.

perf tools: Pass tool context in the the perf_event_ops functions

2011-11-28T12:38:56Z

So that we don't need to have that many globals. Next steps will remove the 'session' pointer, that in most cases is not needed. Then we can rename perf_event_ops to 'perf_tool' that better describes this class hierarchy.

perf hists browser: Warn about lost events

2011-11-02T14:27:23Z

Just like the old perf top --tui and the --stdio version. But because we have the initial menu to choose which event to show in a session with multiple events we can see how many chunks were lost in each of the event types, clarifying which events are being affected the most.

perf top: Reuse the 'report' hist_entry/hists classes

2011-10-07T19:56:44Z

This actually fixes several problems we had in the old 'perf top': 1. Unresolved symbols not show, limitation that came from the old "KernelTop" codebase, to solve it we would need to do changes that would make sym_entry have most of the hist_entry fields. 2. It was using the number of samples, not the sum of sample->period. And brings the --sort code that allows us to have all the views in 'perf report', for instance: [root@emilia ~]# perf top --sort dso PerfTop: 5903 irqs/sec kernel:77.5% exact: 0.0% [1000Hz cycles], (all, 8 CPUs) ------------------------------------------------------------------------------ 31.59% libcrypto.so.1.0.0 21.55% [kernel] 18.57% libpython2.6.so.1.0 7.04% libc-2.12.so 6.99% _backend_agg.so 4.72% sshd 1.48% multiarray.so 1.39% libfreetype.so.6.3.22 1.37% perf 0.71% libgobject-2.0.so.0.2200.5 0.53% [tg3] 0.48% libglib-2.0.so.0.2200.5 0.44% libstdc++.so.6.0.13 0.40% libcairo.so.2.10800.8 0.38% libm-2.12.so 0.34% umath.so 0.30% libgdk-x11-2.0.so.0.1800.9 0.22% libpthread-2.12.so 0.20% libgtk-x11-2.0.so.0.1800.9 0.20% librt-2.12.so 0.15% _path.so 0.13% libpango-1.0.so.0.2800.1 0.11% libatlas.so.3.0 0.09% ft2font.so 0.09% libpangoft2-1.0.so.0.2800.1 0.08% libX11.so.6.3.0 0.07% [vdso] 0.06% cyclictest ^C All the filter lists can be used as well: --dsos, --comms, --symbols, etc. The 'perf report' TUI is also reused, being possible to apply all the zoom operations, do annotation, etc. This change will allow multiple simplifications in the symbol system as well, that will be detailed in upcoming changesets.

perf top: Improve lost events warning

2011-09-29T19:41:38Z

Now it warns everytime that new events are lost. And the TUI also warns now.

perf symbol: Move sym_entry->skip to symbol->ignore

2011-03-11T16:36:01Z

While going thru each of the sym_entry fields looking to reduce it to the set of entries needed when in an active symbols list, 'skip' should really be in symbol, as we set it when loading the symtab. And the space used by the basic symbol allocation remains the same as we had 5 bytes of padding.

perf top: Remove redundant syme->origin field

2011-03-11T16:28:45Z

We can get it from syme->map->dso->kernel (that should be renamed to origin, but leave this for another patch).
