2016-10-19perf c2c report: Add cacheline hists processingJiri Olsa
Store cacheline related entries in nested hist object for each cacheline data. Nested entries are sorted by 'offset' within related cacheline. We will allow specific sort keys to be configured for nested cacheline data entries in following patches.

2016-10-19perf c2c report: Add sample processingJiri Olsa
Adding basic sample processing specific hist_entry allocation callbacks (via hists__add_entry_ops). Overloading 'struct hist_entry' object with new 'struct c2c_hist_entry'. The new hist entry object will carry specific stats and nested hists objects.

2016-10-19perf c2c report: Add dimension supportJiri Olsa
Adding bare bones of dimension support for c2c report. Main interface functions are: c2c_hists__init c2c_hists__reinit which re/initialize 'struct c2c_hists' object with sort/display entries string, in a similar way that setup_sorting function does. We overload the dimension to provide multi line header support for sort/display entries. Also we overload base 'struct perf_hpp_fmt' object with 'struct c2c_fmt' to define c2c specific functions to deal with multi line headers and spans.

2016-10-17perf jevents: Handle events including .c and .oWang Nan
This patch helps with Sukadev's vendor event tree where such events can happen. >From Andi Kleen: Any event including a .c/.o/.bpf currently triggers BPF compilation or loading and then an error. This can happen for some Intel vendor events, which cannot be used. This patch fixes this problem by forbidding BPF file patch containing '{', '}' and ',', make sure flex consumes the leading '{', instead of matching it using a BPF file path. Tested result: $ perf stat -e '{unc_p_clockticks,unc_p_power_state_occupancy.cores_c0}' -a -I 1000 invalid or unsupported event: '{unc_p_clockticks,unc_p_power_state_occupancy.cores_c0}' Run 'perf list' for a list of valid events (as expected, interperted as event) $ perf stat -e 'aaa.c' -a -I 1000 ERROR: problems with path aaa.c: No such file or directory (as expected, interpreted as BPF source) $ perf stat -e 'aaa.ccc' -a -I 1000 invalid or unsupported event: 'aaa.ccc' (as expected, interpreted as event) $ perf stat -e '{aaa.c}' -a -I 1000 ERROR: problems with path aaa.c: No such file or directory event syntax error: '{aaa.c}' <SKIP> (as expected, interpreted as BPF source) $ perf stat -e '{cycles,aaa.c}' -a -I 1000 ERROR: problems with path aaa.c: No such file or directory event syntax error: '{cycles,aaa.c}' (as expected, interpreted as BPF source) Signed-off-by: Wang Nan <wangnan0@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Reported-by: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1475900185-37967-1-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2016-10-13perf top: Fix refreshing hierarchy entries on TUINamhyung Kim
Markus reported that 'perf top --hierarchy' cannot scroll down after refresh. This was because the number of entries are not updated when hierarchy is enabled. Unlike normal report view, hierarchy mode needs to keep its own entry count since it can have non-leaf entries which can expand/collapse.

2016-10-05perf intel-pt: Fix MTC timestamp calculation for large MTC periodsAdrian Hunter
The MTC packet provides a 8-bit slice of CTC which is related to TSC by the TMA packet, however the TMA packet only provides the lower 16 bits of CTC. If mtc_shift > 8 then some of the MTC bits are not in the CTC provided by the TMA packet. Fix-up the last_mtc calculated from the TMA packet by copying the missing bits from the current MTC assuming the least difference between the two, and that the current MTC comes after last_mtc.

2016-10-05perf intel-pt: Fix estimated timestamps for cycle-accurate modeAdrian Hunter
In cycle-accurate mode, timestamps can be calculated from CYC packets. The decoder also estimates timestamps based on the number of instructions since the last timestamp. For that to work in cycle-accurate mode, the instruction count needs to be reset to zero when a timestamp is calculated from a CYC packet, but that wasn't happening, so fix it.

2016-10-03perf pmu-events: Fix fixed counters on IntelAndi Kleen
The JSON event lists use a different encoding for fixed counters than perf for instructions and cycles (ref-cycles is ok) This lead to some common events like inst_retired.any or cpu_clk_unhalted.thread not counting, when specified with their JSON name. Special case these events in the jevents conversion process. I prefer to not touch the JSON files for this, as it's intended that standard JSON files can be just dropped into the perf build without changes.

2016-10-03perf tools: Make alias matching case-insensitiveAndi Kleen
Make alias matching the events parser case-insensitive. This is useful with the JSON events. perf uses lower case events, but the CPU manuals generally use upper case event names. The JSON files use lower case by default too. But if we search case insensitively then users can cut-n-paste the upper case event names. So the following works: % perf stat -e BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL true Performance counter stats for 'true': 305 BR_INST_EXEC.TAKEN_INDIRECT_NEAR_CALL 0.000492799 seconds time elapsed Signed-off-by: Andi Kleen <ak@linux.intel.com> Acked-by: Ingo Molnar <mingo@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: linuxppc-dev@lists.ozlabs.org Link: http://lkml.kernel.org/r/1473978296-20712-17-git-send-email-sukadev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
