2010-07-27perf ui: Consider the refreshed dimensions in ui_browser__showArnaldo Carvalho de Melo1-2/+4
When we call ui_browser__show we may have called ui_browser__refresh_dimensions to check if the maximum lenght for the contained entries changed, such as when zooming in and out DSOs or threads in the hist browser. For that to happen we must delete the old form, that will take care of deleting the vertical scrollbar, etc, and then recreate them, with the new dimensions.

2010-07-27tools/firewire: nosy-dump: work around segfault in decode_fcpStefan Richter1-0/+5
If I run "nosy-dump --view=transaction" with my camcorder on battery instead of mains, it segfaults very quickly because of !t->request. Perhaps this is because of increased likelyhood of incomplete transactions (ack_busy when host writes to camcorder's FCP_Request) and a bug deeper in nosy-dump's transaction housekeeping. This is a quick workaround to get me going. Signed-off-by: Stefan Richter <[email protected]>

This adds nosy-dump, the userspace part of nosy, the IEEE 1394 traffic sniffer for Texas Instruments PCILynx/ PCILynx2 based cards. Author is Kristian Høgsberg. The files added here are taken from git://anongit.freedesktop.org/~krh/nosy commit ee29be97 (2009-11-10) with the following changes by Stefan Richter: - Parts pertaining to the kernel module removed from Makefile. - dist target removed from the Makefile. - Mentioned nosy-dump in the Kconfig help to nosy's kernel component. - Add copyright notice to nosy-dump.c. This is a duplicate of the respective notice in the kernel component nosy.c except for a time span of 2002 - 2006, according to Kristian's git log. "git shortlog decode-fcp.c list.h nosy-dump.[ch]" from nosy's git repository: Jonathan Woithe (1): Save logs on Ctrl-C Kristian Høgsberg (11): Pull over nosy from mercurial repo. Remove some fields from default view, add logging feature. Use infinite time out for poll(), mark more detail fields. Fix byte ordering macro. Add decoding of iso data and lock packets. Add flag to indicate data length field. Add cycle start packet decoding, add --iso and --cycle-start flags. Distinguish between phy-packets and 0-length iso data. Fix transaction and stats view.

2010-07-22perf annotate: Fix handling of goto labels that are valid hex numbersArnaldo Carvalho de Melo1-2/+6
When parsing the objdump disassembly output we can have goto labels that are valid hex numbers and thus get confused with lines with machine code. Handle the common case of a label that has nothing after it and other cases where there is just source code by validating the resulting "ip". It is still possible that we find goto labels that are in the function address range, but only if they are located before the real address we should be OK. A change in the objdump output to have a clear marker separating addresses from the disassembly would come handy, but we would still have to deal with older versions.

2010-07-22x86 cpufreq, perf: Make trace_power_frequency cpufreq driver independentThomas Renninger1-5/+6
and fix the broken case if a core's frequency depends on others. trace_power_frequency was only implemented in a rather ungeneric way in acpi-cpufreq driver's target() function only. -> Move the call to trace_power_frequency to cpufreq.c:cpufreq_notify_transition() where CPUFREQ_POSTCHANGE notifier is triggered. This will support power frequency tracing by all cpufreq drivers. trace_power_frequency did not trace frequency changes correctly when the userspace governor was used or when CPU cores' frequency depend on each other. -> Moving this into the CPUFREQ_POSTCHANGE notifier and pass the cpu which gets switched automatically fixes this. Robert Schoene provided some important fixes on top of my initial quick shot version which are integrated in this patch: - Forgot some changes in power_end trace (TP_printk/variable names) - Variable dummy in power_end must now be cpu_id - Use static 64 bit variable instead of unsigned int for cpu_id [[email protected]: build fix] Signed-off-by: Thomas Renninger <[email protected]> Cc: [email protected] Signed-off-by: Ingo Molnar <[email protected]> Cc: Dave Jones <[email protected]> Acked-by: Arjan van de Ven <[email protected]> Cc: Robert Schoene <[email protected]> Tested-by: Robert Schoene <[email protected]> Signed-off-by: Andrew Morton <[email protected]>

2010-07-16perf: Fix various display bugs with parent filteringFrederic Weisbecker1-5/+16
Hists that have been filtered, because they don't have callchains matching the parent filter, won't be printed. As such, hist_entry__snprintf() returns 0 for them, but we don't control this value and we always print the buffer, which might be untouched and then only made of random stack garbage. Not only does it paint the screen with barf, it also prints the callchains for these hists, even though they have been filtered, since the hist has been filtered as well. We need to check the return value of hist_entry__snprintf() and ignore the hist if it is 0, which means it didn't get any callchain matching the parent filter. This fixes the barf and the undesired callchains.

2010-07-08perf: Sync callchains with period based hitsFrederic Weisbecker3-19/+20
Hists have their hits increased by the event period. And this period based counting is the foundation of all the stats in perf report. But callchains still use the raw number of hits, without taking the period into account. So when we compute the percentage, absolute based percentages are totally broken, and relative ones too in the first parent level. Because we pass the number of events muliplied by their period as the total number of hits to the callchain filtering, while callchains expect this number to be the number of raw hits. perf report -g graph was simply not working, showing no graph unless the min percent was zero. And even there the percentage of the branches was always 0. And may be fractal filtering was broken on the first branch level too. flat also was broken, but it was hidden because of other breakages. Anyway fix this by counting using periods on callchains.

Initialize the callchain radix tree root correctly. When we walk through the parents, we must stop after the root, but since it wasn't well initialized, its parent pointer was random. Also the number of hits was random because uninitialized, hence it was part of the callchain while the root doesn't contain anything.
