| * perf evsel: Adopt fprintf routine from 'perf evlist'Arnaldo Carvalho de Melo2012-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So that we can print all the details when debugging other tools, when we have just evlists and evsels, not a perf.data file.

| * perf evlist: Set the leader in the perf_evlist__config methodArnaldo Carvalho de Melo2012-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we need to ensure the leader is set before configuring the evsel perf_event_attrs. Reducing the boilerplate needed by tools, helping, for instance, 'perf trace', that wasn't setting the leader.

| * perf evsel: Introduce method to request IDs be usedArnaldo Carvalho de Melo2012-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When mmaping multiple events we need to find the right evsel that matches an event in the ring buffer. For that we need to set the PERF_FORMAT_ID bit in perf_event_attr.read_format so that when we read the event fds we get that id to then hash it and be able later to use perf_evlist__id2evsel to find the right evsel. We also need to set the PERF_SAMPLE_ID bit in perf_event_attr.sample_type to ask for that id to be stashed in each sample, so that we can demux it. So add a perf_evsel__set_sample_id() method to do those two things in one operation.

| * perf evsel: Update sample_size when setting sample_type bitsArnaldo Carvalho de Melo2012-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use evsel->sample_size to detect underflows in perf_evsel__parse_sample, but we were failing to update it after perf_evsel__init(), i.e. when we decide, after creating an evsel, that we want some extra field bit set. Fix it by introducing methods to set a bit that will take care of correctly adjusting evsel->sample_size.

| * perf buildid-cache: Add option to show build ids that are missing in the cacheArnaldo Carvalho de Melo2012-12-09

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems not very useful, because it's possible and event more convenient to lookup related symbol by name. Also the output value for both 'baseline' and 'new' data is quite apparent from diff output.

The TUI one then was not used and vfprintf(stderr, ...) was used instead, making the TUI scroll the screen instead of just printing on the last line.

| * perf tools: Fix mmap limitations on 32-bitDavid Miller2012-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a suggested patch to fix the bug I reported at: http://marc.info/?l=linux-kernel&m=135033028924652&w=2 Essentially, there is a hard requirement that when perf analyzes a trace, it must have the entire thing mmap()'d. Therefore the scheme used on 32-bit where we have a fixed (8) number of 32MB mmaps, and cycle through them, simply does not work. One of the reasons this requirement exists is because the iterators maintain references to perf entry objects and those references don't just simply go away when this mmap code decides to cycle an old mmap area out and reuse it. At this point, those entry pointers now point to garbage resulting in unpredictable behavior and crashes. It is better to try to mmap() as much as we can and if we do actually run into address space limitations, the failure of the mmap() call will indicate that and stop processing. I noticed that perf_session->mmap_window is set to a constant in one location, and only used in one other location. So I got rid of it altogether. So we adjust the size of the mmaps[] array to the maximum we could need. On 64-bit we only need one slot. On 32-bit we could need up to 128 (128 * 32MB == 4GB). I've verified that this allows a large (~600MB) perf.data file to be analyzed properly with a 32-bit perf binary, which previously was not possible. Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The perf_event__process_sample function, when not finding a machine associated with a sample, was calling pr_err without a newline, garbling the screen on TUI mode due to a problem introduced by a recent ui_helpline patch.

Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include. This makes sure we get the userspace version of the pt_regs struct. Ideally, we wouldn't have the latter -I flag at all, but unfortunately we want asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI - at least not for x86. I wonder if the bits outside of the __KERNEL__ guards *should* be transferred there. I note also that perf seems to do its dependency handling manually by listing all the header files it might want to use in LIB_H in the Makefile. Can this be changed to use -MD? Note that to do make this work, we need to export and UAPI disintegrate linux/hw_breakpoint.h, which I think should've been exported previously so that perf can access the bits. We have to do this in the same patch to maintain bisectability. Signed-off-by: David Howells <dhowells@redhat.com>

The strbuf_addf() was checking buffer length with a result of vscnprintf() which cannot be greater than that of strbuf_avail(). Since numa topology and pmu mapping info in header were converted to use strbuf, it sometimes caused uninteresting behaviors with the broken strbuf. Fix it by using vsnprintf() which returns desired output string length regardless of the available buffer size and grow the buffer if needed.
