2020-09-22perf tsc: Move out common functions from x86Leo Yan
Functions perf_read_tsc_conversion() and perf_event__synth_time_conv() should work as common functions rather than x86 specific, so move these two functions out from arch/x86 folder and place them into util/tsc.c. Since the function perf_event__synth_time_conv() will be linked in util/tsc.c, remove its weak version.

2020-09-17perf record: Support sample-read topdown metric groupKan Liang
With the hardware TopDown metrics feature, sample-read feature should be supported for a topdown group, e.g., sample a non-topdown event and read a topdown metric group. But the current perf record code errors out. For a topdown metric group, the slots event must be the leader of the group, but the leader slots event doesn't support sampling. To support sample-read the topdown metric group, use the 2nd event of the group as the "leader" for the purposes of sampling. Only the platform with Topdown metic feature supports sample-read the topdown group. Add arch_topdown_sample_read() to indicate whether the topdown group supports sample-read.

2020-07-06perf intel-pt: Fix recording PEBS-via-PT with registersAdrian Hunter
When recording PEBS-via-PT, the kernel will not accept the intel_pt event with register sampling e.g. # perf record --kcore -c 10000 -e '{intel_pt/branch=0/,branch-loads/aux-output/ppp}' -I -- ls -l Error: intel_pt/branch=0/: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat' Fix by suppressing register sampling on the intel_pt evsel.

2020-05-28perf parse-events: Make add PMU verbose output clearerIan Rogers
On a CPU like skylakex an uncore_iio_0 PMU may alias with uncore_iio_free_running_0. The latter PMU doesn't support fc_mask as a parameter and so pmu_config_term fails. Typically parse_events_add_pmu is called in a loop where if one alias succeeds errors are ignored, however, if multiple errors occur parse_events__handle_error will currently give a WARN_ONCE. This change removes the WARN_ONCE in parse_events__handle_error and makes it a pr_debug. It adds verbose messages to parse_events_add_pmu warning that non-fatal errors may occur, while giving details on the pmu and config terms for useful context. pmu_config_term is altered so the failing term and pmu are present in the case of the 'unknown term' error which makes spotting the free_running case more straightforward.

2019-11-26perf maps: Merge 'struct maps' with 'struct map_groups'Arnaldo Carvalho de Melo
And pick the shortest name: 'struct maps'. The split existed because we used to have two groups of maps, one for functions and one for variables, but that only complicated things, sometimes we needed to figure out what was at some address and then had to first try it on the functions group and if that failed, fall back to the variables one. That split is long gone, so for quite a while we had only one struct maps per struct map_groups, simplify things by combining those structs. First patch is the minimum needed to merge both, follow up patches will rename 'thread->mg' to 'thread->maps', etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-hom6639ro7020o708trhxh59@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2019-08-31perf intel-pt: Use shared x86 insn decoderJosh Poimboeuf
Now that there's a common version of the decoder for all tools, use it instead of the local copy. Also use perf's check-headers.sh script to diff the decoder files to make sure they remain in sync with the kernel version. Objtool has a similar check. Committer notes: Had to keep this all pointing explicitely to x86 headers/files, i.e. instead of asm/isnn.h we had to use ../include/asm/insn.h when the files were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h". This way we continue to be able to process perf.data files with Intel PT traces in distros other than x86. Also fixed up the awk script paths to use $(srcdir)/tools/arch instead or relative directories so that we keep detached tarballs (make help | grep perf) working. For now the include lines in these headers are being ignored so as not to flag false reports of kernel/tools out of sync.
