When merging counts from multiple uncore PMUs the metric is only computed for the metric leader. When merging/aggregation is disabled, prior to this patch just the leader's metric would be computed. Fix this by computing the metric for each PMU.

Pass metric_expr and evsel rather than specific variables from the struct, thereby reducing the number of arguments. This will enable later fixes. To reduce the size of the diff, local variables are added to match the previous parameter names. This isn't done in the case of "name" as evsel->name is more intention revealing. A whitespace issue is also addressed. Signed-off-by:

Currently, the instructions of samples are shown as raw hex strings which are hard to read. x86 has a special option '--xed' to disassemble the hex string via intel XED tool. Here we use capstone as our disassembler engine to give more friendly instructions. We select libcapstone because capstone can provide more insn details. Perf will fallback to raw instructions if libcapstone is not available. The advantages compared to XED tool: * Support arm, arm64, x86-32, x86_64 (more could be supported), xed only for x86_64. * Immediate address operands are shown as symbol+offs. Signed-off-by:

I got a strange error on ARM to fail on processing FINISHED_ROUND record. It turned out that it was failing in symbol__alloc_hist() because the symbol size is too big. When a sample is captured on a specific BPF program, it failed. I've added a debug code and found the end address of the symbol is from the next module which is placed far way. ffff800008795778-ffff80000879d6d8: bpf_prog_1bac53b8aac4bc58_netcg_sock [bpf] ffff80000879d6d8-ffff80000ad656b4: bpf_prog_76867454b5944e15_netcg_getsockopt [bpf] ffff80000ad656b4-ffffd69b7af74048: bpf_prog_1d50286d2eb1be85_hn_egress [bpf] <---------- here ffffd69b7af74048-ffffd69b7af74048: $x.5 [sha3_generic] ffffd69b7af74048-ffffd69b7af740b8: crypto_sha3_init [sha3_generic] ffffd69b7af740b8-ffffd69b7af741e0: crypto_sha3_update [sha3_generic] The logic in symbols__fixup_end() just uses curr->start to update the prev->end. But in this case, it won't work as it's too different. I think ARM has a different kernel memory layout for modules and BPF than on x86. Actually there's a logic to handle kernel and module boundary. Let's do the same for symbols between different modules. Signed-off-by:

Top-Down Microarchitecture Analysis (TMA) metrics simplify cycle-accounting using microarchitecture-abstracted metrics organized in one hierarchy. This update is from version 4.5 to 4.7. The update includes: - tma_info_bottleneck* metrics, an abstraction or summarization of the 100+ TMA tree nodes into 12-entry familiar performance metrics. - Reduce number of events (multiplexing) for tma_info_system_gflops, tma_info_core_flopc, tma_info_inst_mix_ipflop and tma_ports_utilized_0. - Fixes for tma_info_bottleneck_mispredictions and tma_info_bad_spec_branch_misprediction_cost. - New tma_info_inst_mix_ippause metric. - tma_serializing_operation is raised to level 3. - Swapped tma_info_core_ilp (becomes per SMT thread) and tma_info_pipeline_execute (per physical core). - tma_nop_instructions and tma_shuffles_256b are lowered to level 4 under tma_other_light_ops_group. - Reduced number of events when SMT is off. - Tuned thresholds for tma_info_bottleneck_branching_overhead, tma_fetch_bandwidth and tma_ports_utilized_3m. The update came from: https://github.com/intel/perfmon/pull/140 https://github.com/intel/perfmon/pull/138 Running the script: https://github.com/intel/perfmon/blob/main/scripts/create_perf_json.pySigned-off-by:

If we instead decide to generate vmlinux.h from BTF info, it will be there: $ pahole timespec64 struct timespec64 { time64_t tv_sec; /* 0 8 */ long int tv_nsec; /* 8 8 */ /* size: 16, cachelines: 1, members: 2 */ /* last cacheline: 16 bytes */ }; $ pahole manages to find it from /sys/kernel/btf/vmlinux, that is generated from the kernel types. With this linux/bpf.h doesn't need to be included, as its already in the minimalistic tools/perf/util/bpf_skel/vmlinux/vmlinux.h file or what we need comes when generating a vmlinux.h file from BTF info, i.e. when using GEN_VMLINUX_H=1, as noticed by Namyung in a build break before removing linux/bpf.h.
