2011-11-03perf top: Fix live annotation in the --stdio interfaceArnaldo Carvalho de Melo1-1/+2
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.

2011-10-27perf hists: Fix recalculation of total_period when sorting entriesArnaldo Carvalho de Melo1-2/+1
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. Problem introduced when developing threaded addition of new batches of hist_entries, i.e. post v3.1.

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"?).

2011-10-20perf tools: Fix tracing info recordingJiri Olsa3-29/+123
Fixing the way the tracing information is stored within record command. The current implementation is causing issues for pipe output. Following commands fail currently: perf script syscall-counts ls perf record -e syscalls:sys_exit_read ls | ./perf report -i - The tracing information is part of the perf data file. It contains several files from within the tracing debugfs and procs directories. Beside some static header files, for each tracing event the format file is added. The /proc/kallsyms file is also added. The tracing data are stored with preceeding size. This is causing some dificulties for pipe output, since there's no way to tell debugfs/proc file size before reading it. So, for pipe output, all the debugfs files were read twice. Once to get the overall size and once to store the content itself. This can cause problem in case any of these file changed, within the storage time. To fix this behaviour and ensure the integrity of the tracing data, we: - read debugfs/proc file into the temp file - get temp file size and dump it to the pipe - dump the temp file contents to the pipe Cc: Eric Dumazet <eric.dumazet@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Neil Horman <nhorman@tuxdriver.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/20111020135943.GD2092@jolsa.brq.redhat.com Signed-off-by: Jiri Olsa <jolsa@redhat.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2011-10-20perf hists: Don't decay total_period for filtered entriesArnaldo Carvalho de Melo1-3/+8
Following the 'perf report' model we don't zap hist_entry instances from the rb tree, we just keep them with he->filtered set to a mask of the filters applied to it (thread, parent, DSO so far). In top we need to decay even filtered entries, but we better not touch total_period for them... Now everything seems to work when filters are applied on top as they worked in 'report', i.e. both dynamic and static hist entry browsing works with filters.

2011-10-19perf tools: handle endianness of feature bitmapDavid Ahern1-11/+31
Feature bitmap is declared as an array of unsigned longs -- not good since its size can differ between the host that generated the data file and the host analyzing the file. We need to handle endianness, but we don't know the size of the unsigned long where the file was generated. Take a best guess at determining it: try 64-bit swap first (ie., file created on a 64-bit host), and check if the hostname feature bit is set (this feature bit is forced on as of fbe96f2). If the bit is not, undo the 64-bit swap and try a 32-bit swap. If the hostname bit is still not set (e.g., older data file), punt and fallback to the original behavior -- clearing all feature bits and setting buildid.

2011-10-18tools, slub: Fix off-by-one buffer corruption after readlink() callThomas Jarosch1-1/+1
readlink() never zero terminates the provided buffer. Therefore we already do buffer[count] = 0; This leads to an off-by-one buffer corruption as readlink() might return the full size of the buffer. The common technique is to reduce the buffer size by one. Another fix would be to check if (count < 0 || count == sizeof(buffer)) fatal(); Reducing the buffer size by one is easier IMHO.
