Data profiling: - Associate samples that identify loads and stores with data structures. This uses events available on Intel, AMD and others and DWARF info: # To get memory access samples in kernel for 1 second (on Intel) $ perf mem record -a -K --ldlat=4 -- sleep 1 # Similar for the AMD (but it requires 6.3+ kernel for BPF filters) $ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1 Then, amongst several modes of post processing, one can do things like: $ perf report -s type,typeoff --hierarchy --group --stdio ... # # Samples: 10K of events 'cpu/mem-loads,ldlat=4/P, cpu/mem-stores/P, dummy:u' # Event count (approx.): 602758064 # # Overhead Data Type / Data Type Offset # ........................... ............................ # 26.09% 3.28% 0.00% long unsigned int 26.09% 3.28% 0.00% long unsigned int +0 (no field) 18.48% 0.73% 0.00% struct page 10.83% 0.02% 0.00% struct page +8 (lru.next) 3.90% 0.28% 0.00% struct page +0 (flags) 3.45% 0.06% 0.00% struct page +24 (mapping) 0.25% 0.28% 0.00% struct page +48 (_mapcount.counter) 0.02% 0.06% 0.00% struct page +32 (index) 0.02% 0.00% 0.00% struct page +52 (_refcount.counter) 0.02% 0.01% 0.00% struct page +56 (memcg_data) 0.00% 0.01% 0.00% struct page +16 (lru.prev) 15.37% 17.54% 0.00% (stack operation) 15.37% 17.54% 0.00% (stack operation) +0 (no field) 11.71% 50.27% 0.00% (unknown) 11.71% 50.27% 0.00% (unknown) +0 (no field) $ perf annotate --data-type ...

This is the initial implementation, please use it and report impressions and bugs. Make sure the kernel-debuginfo packages match the running kernel. The 'perf report' phase for non short perf.data files may take a while. There is a great article about it on LWN: https://lwn.net/Articles/955709/ - "Data-type profiling for perf" One last test I did while writing this text, on a AMD Ryzen 5950X, using a distro kernel, while doing a simple 'find /' on an otherwise idle system resulted in: # uname -r 6.6.9-100.fc38.x86_64 # perf -vv | grep BPF_ bpf: [ on ] # HAVE_LIBBPF_SUPPORT bpf_skeletons: [ on ] # HAVE_BPF_SKEL # rpm -qa | grep kernel-debuginfo kernel-debuginfo-common-x86_64-6.6.9-100.fc38.x86_64 kernel-debuginfo-6.6.9-100.fc38.x86_64 # # perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' ^C[ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 2.199 MB perf.data (2913 samples) ] # # ls -la perf.data -rw-------. 1 root root 2346486 Jan 9 18:36 perf.data # perf evlist ibs_op// dummy:u # perf evlist -v ibs_op//: type: 11, size: 136, config: 0, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|ADDR|CPU|PERIOD|IDENTIFIER|DATA_SRC|WEIGHT, read_format: ID, disabled: 1, inherit: 1, freq: 1, sample_id_all: 1 dummy:u: type: 1 (PERF_TYPE_SOFTWARE), size: 136, config: 0x9 (PERF_COUNT_SW_DUMMY), { sample_period, sample_freq }: 1, sample_type: IP|TID|TIME|ADDR|CPU|IDENTIFIER|DATA_SRC|WEIGHT, read_format: ID, inherit: 1, exclude_kernel: 1, exclude_hv: 1, mmap: 1, comm: 1, task: 1, mmap_data: 1, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1, ksymbol: 1, bpf_event: 1 # # perf report -s type,typeoff --hierarchy --group --stdio # Total Lost Samples: 0 # # Samples: 2K of events 'ibs_op//, dummy:u' # Event count (approx.): 1904553038 # # Overhead Data Type / Data Type Offset # ................... ............................ # 73.70% 0.00% (unknown) 73.70% 0.00% (unknown) +0 (no field) 3.01% 0.00% long unsigned int 3.00% 0.00% long unsigned int +0 (no field) 0.01% 0.00% long unsigned int +2 (no field) 2.73% 0.00% struct task_struct 1.71% 0.00% struct task_struct +52 (on_cpu) 0.38% 0.00% struct task_struct +2104 (rcu_read_unlock_special.b.blocked) 0.23% 0.00% struct task_struct +2100 (rcu_read_lock_nesting) 0.14% 0.00% struct task_struct +2384 () 0.06% 0.00% struct task_struct +3096 (signal) 0.05% 0.00% struct task_struct +3616 (cgroups) 0.05% 0.00% struct task_struct +2344 (active_mm) 0.02% 0.00% struct task_struct +46 (flags) 0.02% 0.00% struct task_struct +2096 (migration_disabled) 0.01% 0.00% struct task_struct +24 (__state) 0.01% 0.00% struct task_struct +3956 (mm_cid_active) 0.01% 0.00% struct task_struct +1048 (cpus_ptr) 0.01% 0.00% struct task_struct +184 (se.group_node.next) 0.01% 0.00% struct task_struct +20 (thread_info.cpu) 0.00% 0.00% struct task_struct +104 (on_rq) 0.00% 0.00% struct task_struct +2456 (pid) 1.36% 0.00% struct module 0.59% 0.00% struct module +952 (kallsyms) 0.42% 0.00% struct module +0 (state) 0.23% 0.00% struct module +8 (list.next) 0.12% 0.00% struct module +216 (syms) 0.95% 0.00% struct inode 0.41% 0.00% struct inode +40 (i_sb) 0.22% 0.00% struct inode +0 (i_mode) 0.06% 0.00% struct inode +76 (i_rdev) 0.06% 0.00% struct inode +56 (i_security) perf top/report: - Don't ignore job control, allowing control+Z + bg to work. - Add s390 raw data interpretation for PAI (Processor Activity Instrumentation) counters. perf archive: - Add new option '--all' to pack perf.data with DSOs. - Add new option '--unpack' to expand tarballs. Initialization speedups: - Lazily initialize zstd streams to save memory when not using it. - Lazily allocate/size mmap event copy. - Lazy load kernel symbols in 'perf record'. - Be lazier in allocating lost samples buffer in 'perf record'. - Don't synthesize BPF events when disabled via the command line (perf record --no-bpf-event). Assorted improvements: - Show note on AMD systems that the :p, :pp, :ppp and :P are all the same, as IBS (Instruction Based Sampling) is used and it is inherentely precise, not having levels of precision like in Intel systems. - When 'cycles' isn't available, fall back to the "task-clock" event when not system wide, not to 'cpu-clock'. - Add --debug-file option to redirect debug output, e.g.: $ perf --debug-file /tmp/perf.log record -v true - Shrink 'struct map' to under one cacheline by avoiding function pointers for selecting if addresses are identity or DSO relative, and using just a byte for some boolean struct members. - Resolve the arch specific strerrno just once to use in perf_env__arch_strerrno(). - Reduce memory for recording PERF_RECORD_LOST_SAMPLES event. Assorted fixes: - Fix the default 'perf top' usage on Intel hybrid systems, now it starts with a browser showing the number of samples for Efficiency (cpu_atom/cycles/P) and Performance (cpu_core/cycles/P). This behaviour is similar on ARM64, with its respective set of big.LITTLE processors. - Fix segfault on build_mem_topology() error path. - Fix 'perf mem' error on hybrid related to availability of mem event in a PMU. - Fix missing reference count gets (map, maps) in the db-export code. - Avoid recursively taking env->bpf_progs.lock in the 'perf_env' code. - Use the newly introduced maps__for_each_map() to add missing locking around iteration of 'struct map' entries. - Parse NOTE segments until the build id is found, don't stop on the first one, ELF files may have several such NOTE segments. - Remove 'egrep' usage, its deprecated, use 'grep -E' instead. - Warn first about missing libelf, not libbpf, that depends on libelf. - Use alternative to 'find ... -printf' as this isn't supported in busybox. - Address python 3.6 DeprecationWarning for string scapes. - Fix memory leak in uniq() in libsubcmd. - Fix man page formatting for 'perf lock' - Fix some spelling mistakes. perf tests: - Fail shell tests that needs some symbol in perf itself if it is stripped. These tests check if a symbol is resolved, if some hot function is indeed detected by profiling, etc. - The 'perf test sigtrap' test is currently failing on PREEMPT_RT, skip it if sleeping spinlocks are detected (using BTF) and point to the mailing list discussion about it. This test is also being skipped on several architectures (powerpc, s390x, arm and aarch64) due to other pending issues with intruction breakpoints. - Adjust test case perf record offcpu profiling tests for s390. - Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest, addressing issues caused by the fallback from cycles to task-clock done in this release. - Fix mask for VG register in the user-regs test. - Use shellcheck on 'perf test' shell scripts automatically to make sure changes don't introduce things it flags as problematic. - Add option to change objdump binary and allow it to be set via 'perf config'. - Add basic 'perf script', 'perf list --json" and 'perf diff' tests. - Basic branch counter support. - Make DSO tests a suite rather than individual. - Remove atomics from test_loop to avoid test failures. - Fix call chain match on powerpc for the record+probe_libc_inet_pton test. - Improve Intel hybrid tests. Vendor event files (JSON): powerpc: - Update datasource event name to fix duplicate events on IBM's Power10. - Add PVN for HX-C2000 CPU with Power8 Architecture. Intel: - Alderlake/rocketlake metric fixes. - Update emeraldrapids events to v1.02. - Update icelakex events to v1.23. - Update sapphirerapids events to v1.17. - Add skx, clx, icx and spr upi bandwidth metric. AMD: - Add Zen 4 memory controller events. RISC-V: - Add StarFive Dubhe-80 and Dubhe-90 JSON files. https://www.starfivetech.com/en/site/cpu-u - Add T-HEAD C9xx JSON file. https://github.com/riscv-software-src/opensbi/blob/master/docs/platform/thead-c9xx.md ARM64: - Remove UTF-8 characters from cmn.json, that were causing build failure in some distros. - Add core PMU events and metrics for Ampere One X. - Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT libperf: - Rename several perf_cpu_map constructor names to clarify what they really do. - Ditto for some other methods, coping with some issues in their semantics, like perf_cpu_map__empty() -> perf_cpu_map__has_any_cpu_or_is_empty(). - Document perf_cpu_map__nr()'s behavior perf stat: - Exit if parse groups fails. - Combine the -A/--no-aggr and --no-merge options. - Fix help message for --metric-no-threshold option. Hardware tracing: ARM64 CoreSight: - Bump minimum OpenCSD version to ensure a bugfix is present. - Add 'T' itrace option for timestamp trace - Set start vm addr of exectable file to 0 and don't ignore first sample on the arm-cs-trace-disasm.py 'perf script'.
