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 [akpm@linux-foundation.org: build fix] Signed-off-by: NThomas Renninger <trenn@suse.de> Cc: davej@codemonkey.org.uk Signed-off-by: NIngo Molnar <mingo@elte.hu> Cc: Dave Jones <davej@codemonkey.org.uk> Acked-by: NArjan van de Ven <arjan@infradead.org> Cc: Robert Schoene <robert.schoene@tu-dresden.de> Tested-by: NRobert Schoene <robert.schoene@tu-dresden.de> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org>

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.

由 Ian Munsie 提交于
At exit, perf record will kill the process it was profiling by sending a SIGTERM to child_pid (if it had been initialised), but in certain situations child_pid may be 0 and perf would mistakenly kill more processes than intended. child_pid is set to the return of fork() to either 0 or the pid of the child. Ordinarily this would not present an issue as the child calls execvp to spawn the process to be profiled and would therefore never run it's sig_atexit and never attempt to kill pid 0. However, if a nonexistant binary had been passed in to perf record the call to execvp would fail and child_pid would be left set to 0. The child would then exit and it's atexit handler, finding that child_pid was initialised to 0, would call kill(0, SIGTERM), resulting in every process within it's process group being killed. In the case that perf was being run directly from the shell this typically would not be an issue as the shell isolates the process. However, if perf was being called from another program it could kill unexpected processes, which may even include X. This patch changes the logic of the test for whether child_pid was initialised to only consider positive pids as valid, thereby never attempting to kill pid 0. Cc: David S.

Currently symbol resolution does not work for 64-bit programs on architectures that use function descriptors such as ppc64. The problem is that a symbol doesn't point to a text address, it points to a data area that contains (amongst other things) a pointer to the text address. We look for a section called ".opd" which is the function descriptor area. To create the full symbol table, when we see a symbol in the function descriptor section we load the first pointer and use that as the text address.
