* perf jit: Remove unecessary padding in jitdump fileStephane Eranian2016-10-241-37/+1
| | | | | | | | | | | | | | | | This patch removes all the string padding generated in the jitdump file. They are not necessary and were adding unnecessary complexity. Modern processors can handle unaligned accesses quite well. The perf.data/ jitdump file are always post-processed, no need to add extra complexity for no real gain.

* perf jit: Enable jitdump support without dwarfMaciej Debski2016-10-244-4/+11
| | | | | | | | | | | | | | | | | | | | | | This patch modifies the build dependencies on the jitdump support in perf. As it stands jitdump was wrongfully made dependent 100% on using DWARF. However, the dwarf dependency, only exist if generating the source line table in genelf_debug.c. The rest of the support does not need DWARF. This patch removes the dependency on DWARF for the entire jitdump support. It keeps it only for the genelf_debug.c support.

* perf jit: Add NT_GNU_BUILD_ID definition for older distrosArnaldo Carvalho de Melo2016-10-241-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Such as CentOS5, where such define is not present in elf.h. This file, genelf.c, wasn't being built for several systems, because it mistakenly was conditional on some DWARF features, now that it is just needing libelf, after "perf jit: Enable jitdump support without dwarf" it fails. So, as preparation for "perf jit: Enable jitdump support without dwarf", conditionally define it, if not available.

* perf jit: Avoid returning garbage for a ret variableArnaldo Carvalho de Melo2016-10-241-1/+1

* perf tools: Implement branch_type event parameterAndi Kleen2016-10-245-43/+71
| | | | | | | | | | | | | | | | | | | | | | It can be useful to specify branch type state per event, for example if we want to collect both software trace points and last branch PMU events in a single collection. Currently this doesn't work because the software trace point errors out with -b. There was already a branch-type parameter to configure branch sample types per event in the parser, but it was stubbed out. This patch implements the necessary plumbing to actually enable it. Now: $ perf record -e sched:sched_switch,cpu/cpu-cycles,branch_type=any/ ... works.

The instruction buffer is presently used for debugging, so rename its size macro from INTEL_PT_INSN_DBG_BUF_SZ to INTEL_PT_INSN_BUF_SZ, and use it everywhere. Note that the maximum instruction size is 15 which is a less efficient size to copy than 16, which is why a separate buffer size is used.

It allows you to track down cacheline contention. The tool is based on x86's load latency and precise store facility events provided by Intel CPUs. It was tested by Joe Mario and has proven to be useful, finding some cacheline contentions. Joe also wrote a blog about c2c tool with examples: https://joemario.github.io/blog/2016/09/01/c2c-blog/ Excerpt of the content on this site: --- At a high level, “perf c2c” will show you: * The cachelines where false sharing was detected. * The readers and writers to those cachelines, and the offsets where those accesses occurred. * The pid, tid, instruction addr, function name, binary object name for those readers and writers. * The source file and line number for each reader and writer. * The average load latency for the loads to those cachelines. * Which numa nodes the samples a cacheline came from and which CPUs were involved. Using perf c2c is similar to using the Linux perf tool today. First collect data with “perf c2c record” Then generate a report output with “perf c2c report” --- There one finds extensive details on using the tool, with tips on reducing the volume of samples while still capturing enough to do its job.
