* perf evsel: Rename perf_evsel__{str,int}val() and other tracepoint field ↵Arnaldo Carvalho de Melo2020-05-051-4/+4
| | | | | | | | | | | | metehods to to evsel__*() As those are not 'struct evsel' methods, not part of tools/lib/perf/, aka libperf, to whom the perf_ prefix belongs.

* perf kvm s390: Add missing string.h headerArnaldo Carvalho de Melo2019-08-221-0/+1

| | | | | | | | | | | | | | | | | | | Rename struct perf_evsel to struct evsel, so we don't have a name clash when we add struct perf_evsel in libperf.

* perf kvm: Fix subcommands on s390Thomas Richter2018-07-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | With commit eca0fa28cd0d ("perf record: Provide detailed information on s390 CPU") s390 platform provides detailed type/model/capacity information in the CPU identifier string instead of just "IBM/S390". This breaks 'perf kvm' support which uses hard coded string IBM/S390 to compare with the CPU identifier string. Fix this by changing the comparison.

* perf kvm/{x86,s390}: Remove const from kvm_events_tpHemant Kumar2016-01-291-1/+1
| | | | | | | | | | | | | | | | | | | This patch removes the "const" qualifier from kvm_events_tp declaration to account for the fact that some architectures may need to update this variable dynamically. For instance, powerpc will need to update this variable dynamically depending on the machine type.

* perf kvm/{x86,s390}: Remove dependency on uapi/kvm_perf.hHemant Kumar2016-01-291-1/+7
| | | | | | | | | | | | | | | | | | | Its better to remove the dependency on uapi/kvm_perf.h to allow dynamic discovery of kvm events (if its needed). To do this, some extern variables have been introduced with which we can keep the generic functions generic.

* perf kvm: Add stat support on s390Alexander Yarygin2014-07-161-0/+105
On s390, the vmexit event has a tree-like structure: between exit_event_begin and exit_event_end several other events may happen and with each of them refining the previous ones. This patch adds a decoder for such events to the generic code and also the files <asm/kvm_perf.h> and kvm-stat.c for s390. Commands 'perf kvm stat record', 'report' and 'live' are supported.
