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.

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: NDeng-Cheng Zhu <dczhu@mips.com> Tested-by: NDeng-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.orgSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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.comSigned-off-by: NJiri Olsa <jolsa@redhat.com> Signed-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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.

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 fbe96f29). 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.

When compiling an i386_defconfig kernel with gcc-4.6.1-9.fc15.i686, I noticed a warning about the asm operand for test_bit in kprobes' can_boost. I discovered that this caused only the first long of twobyte_is_boostable[] to be output. Jakub filed and fixed gcc PR50571 to correct the warning and this output issue. But to solve it for less current gcc, we can make kprobes' twobyte_is_boostable[] volatile, and it won't be optimized out.

Atomic64 is now a valid type in Linux. Archs that do not have their own version of atomic64 operators are to use the generic operations. The m32r architecture needs to define GENERIC_ATOMIC64.
