2012-12-09perf symbols: Ignore ABS symbols when loading data mapsNamhyung Kim
When loading symbols in a data mapping, ABS symbols (which has a value of SHN_ABS in its st_shndx) failed at elf_getscn(). And it marks the loading as a failure so already loaded symbols cannot be fixed up. I'm not sure what should be done. Just ignore them for now. :) Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1353502185-26521-19-git-send-email-eranian@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2012-12-09perf hists: Introduce perf_hpp__list for period related columnsJiri Olsa
Adding perf_hpp__list list to register and contain all period related columns the command is interested in. This way we get rid of static array holding all possible columns and enable commands to register their own columns. It'll be handy for diff command in future to process and display data for multiple files.

2012-12-09perf tools: Fix mmap limitations on 32-bitDavid Miller
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.

2012-12-09perf top: Add missing newline on pr_err callArnaldo Carvalho de Melo
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. On --stdio it would just concatenate the messages for each sample with no machine associated, fix it by adding the newline.

2012-11-19perf: Make perf build for x86 with UAPI disintegration appliedDavid Howells
Make perf build for x86 once the UAPI disintegration patches for that arch have been applied by adding the appropriate -I flags - in the right order - and then converting some #includes that use ../.. notation to find main kernel headerfiles to use <asm/foo.h> and <linux/foo.h> instead. 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>

2012-11-14perf tools: Add basic event modifier sanity checkJiri Olsa
Updating event parser to allow any non zero string containing [ukhpGH] characters for event modifier. The modifier sanity is checked later in parse-event object logic.

2012-11-14perf tools: Ensure single disable call per event in record comandJiri Olsa
It's possible we issue the event disable ioctl multiple times until we read the final portion of the mmap buffer.

2012-11-14perf tools: Fix 'disabled' attribute config for record commandJiri Olsa
Currently the record command sets all events initially as disabled. There's non conditional perf_evlist__enable call, that enables all events before we exec tracee program. That actually screws whole enable_on_exec logic, because the event is enabled before the traced program got executed. What we actually want is: 1) For any type of traced program: - all independent events and group leaders are disabled - all group members are enabled Group members are ruled by group leaders. They need to be enabled, because the group scheduling relies on that. 2) For traced programs executed by perf: - all independent events and group leaders have enable_on_exec set - we don't specifically enable or disable any event during the record command Independent events and group leaders are initially disabled and get enabled by exec. Group members are ruled by group leaders as stated in 1). 3) For traced programs attached by perf (pid/tid): - we specifically enable or disable all events during the record command When attaching events to already running traced we enable/disable events specifically, as there's no initial traced exec call. Fixing appropriate perf_event_attr test case to cover this change.

2012-11-14perf tools: Fix attributes for '{}' defined event groupsJiri Olsa
Fixing events attributes for groups defined via '{}'. Currently 'enable_on_exec' attribute in record command and both 'disabled ' and 'enable_on_exec' attributes in stat command are set based on the 'group' option. This eliminates proper setup for '{}' defined groups as they don't set 'group' option. Making above attributes values based on the 'evsel->leader' as this is common to both group definition. Moving perf_evlist__set_leader call within builtin-record ahead perf_evlist__config_attrs call, because the latter needs possible group leader links in place.
