2011-11-28perf tools: make -C consistent across commands (for cpu list arg)David Ahern
Currently the meaning of -C varies by perf command: for perf-top, perf-stat, perf-record it means cpu list. For perf-report it means comm list. Then perf-annotate, perf-report and perf-script use -c for cpu list. Fix annotate, report and script to use -C for cpu list to be consistent with top, stat and record. This means report needs to use -c for comm list which does introduce a backward compatibility change. v1 -> v2 - update perf-script.txt too Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1321209008-7004-1-git-send-email-dsahern@gmail.com Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

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.

2011-11-28perf tools: Simplify debugfs mountpoint handling codeArnaldo Carvalho de Melo
We don't need to have two PATH_MAX char sized arrays holding it, just one in util/debugfs.c will do. Also rename debugfs_path to tracing_events_path, as it is not the path to debugfs, that is debugfs_mountpoint. Both are now accessible. This will allow accessing this code in the perf python binding without having to drag in perf.c and util/parse-events.c. The defaults for these variables are the canonical "/sys/kernel/debug" and "/sys/kernel/debug/tracing/events/", removing the need for simple tools to call debugfs_mount(NULL).

2011-11-03perf top: Fix live annotation in the --stdio interfaceArnaldo Carvalho de Melo
In the old --stdio interface the annotation is done just after one selects a symbol, while in --tui, now the default when the required libs are installed, we annotate all symbols with samples so that when annotation is asked we see what happened recently on that symbol. To achieve that the --stdio variant checks if the hist_entry being processed is the one selected by the user via the 's' hotkey. What happens now that we share the hist_entry abstractions with 'perf report' is that for minimizing locking contention multiple rb_trees are used, one for collecting the samples and other to browse/show them after resorting it by number of samples and decay them, which is done periodically. So the simple test in record_precise_ip doesn't work as we move hist_entries between those rb_trees. To fix it just check that the underlying struct symbol associated with those hist_entries is the same.

We were doing parts of it in hists__collapse_resort and parts of it in hists__output_resort, leading to a bogus total_period. Fix it by doing just the filtering operation when collapsing because there we know that the Zoom operations adds filters just what is in hists->entries, not to the new batch of entries being collapsed. And move all the nr_entries + total_period recalculation to hists__output_resort since we will traverse all entries anyway there.

Right now let it work just like the other browsers: in full screen, at the top left corner.

2011-10-26perf ui: Improve handling sigwinch a bitArnaldo Carvalho de Melo
No need to unblock it at each ui__getch() and also allow other users to check if a resize is needed, or force an refresh of terminal dimensions. The 'force' one shouldn't be needed, but its in a slow path, so leave it like that for now, I'll revisit this another day.

Fix up conflicts in arch/x86/kernel/kprobes.c manually. Ingo's tree did the insane "add volatile to const array", which just doesn't make sense ("volatile const"?). But we could remove the const *and* make the array volatile to make doubly sure that gcc doesn't optimize it away.. Also fix up kernel/trace/ring_buffer.c non-data-conflicts manually: the reader_lock has been turned into a raw lock by the core locking merge, and there was a new user of it introduced in this perf core merge. Make sure that new use also uses the raw accessor functions.
2011-10-26perf evlist: Fix grouping of multiple eventsArnaldo Carvalho de Melo
The __perf_evsel__open routing was grouping just the threads for that specific events per cpu when we want to group all threads in all events to the first fd opened on that cpu. So pass the xyarray with the first event, where the other events will be able to get that first per cpu fd. At some point top and record will switch to using perf_evlist__open that takes care of this detail and probably will also handle the fallback from hw to soft counters, etc. Reported-by: Deng-Cheng Zhu <dczhu@mips.com> Tested-by: Deng-Cheng Zhu <dczhu@mips.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-ebm34rh098i9y9v4cytfdp0x@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2011-10-21perf symbols: Increase symbol KSYM_NAME_LEN sizeRicardo Ribalda Delgado
Fglrx propietary driver has symbol names over 128 chars (:S). This breaks the function kallsyms__parse. This fix increases the size of KSYM_NAME_LEN, so kallsyms__parse can work on such kernels. The only counterparty, is that such function requires 128 more bytes to work.
