Merge tag 'perf-tools-for-v6.12-1-2024-09-19' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf tools updates from Arnaldo Carvalho de Melo:
- Use BPF + BTF to collect and pretty print syscall and tracepoint arguments in 'perf trace', done as an GSoC activity
- Data-type profiling improvements:
- Cache debuginfo to speed up data type resolution
- Add the 'typecln' sort order, to show which cacheline in a target is hot or cold. The following shows members in the cfs_rq's first cache line:
$ perf report -s type,typecln,typeoff -H ... - 2.67% struct cfs_rq + 1.23% struct cfs_rq: cache-line 2 + 0.57% struct cfs_rq: cache-line 4 + 0.46% struct cfs_rq: cache-line 6 - 0.41% struct cfs_rq: cache-line 0 0.39% struct cfs_rq +0x14 (h_nr_running) 0.02% struct cfs_rq +0x38 (tasks_timeline.rb_leftmost)
- When a typedef resolves to a unnamed struct, use the typedef name
- When a struct has just one basic type field (int, etc), resolve the type sort order to the name of the struct, not the type of the field
- Support type folding/unfolding in the data-type annotation TUI
- Fix bitfields offsets and sizes
- Initial support for PowerPC, using libcapstone and the usual objdump disassembly parsing routines
- Add support for disassembling and addr2line using the LLVM libraries, speeding up those operations
- Support --addr2line option in 'perf script' as with other tools
- Intel branch counters (LBR event logging) support, only available in recent Intel processors, for instance, the new "brcntr" field can be asked from 'perf script' to print the information collected from this feature:
$ perf script -F +brstackinsn,+brcntr
# Branch counter abbr list: # branch-instructions:ppp = A # branch-misses = B # '-' No event occurs # '+' Event occurrences may be lost due to branch counter saturated tchain_edit 332203 3366329.405674: 53030 branch-instructions:ppp: 401781 f3+0x2c (home/sdp/test/tchain_edit) f3+31: 0000000000401774 insn: eb 04 br_cntr: AA # PRED 5 cycles [5] 000000000040177a insn: 81 7d fc 0f 27 00 00 0000000000401781 insn: 7e e3 br_cntr: A # PRED 1 cycles [6] 2.00 IPC 0000000000401766 insn: 8b 45 fc 0000000000401769 insn: 83 e0 01 000000000040176c insn: 85 c0 000000000040176e insn: 74 06 br_cntr: A # PRED 1 cycles [7] 4.00 IPC 0000000000401776 insn: 83 45 fc 01 000000000040177a insn: 81 7d fc 0f 27 00 00 0000000000401781 insn: 7e e3 br_cntr: A # PRED 7 cycles [14] 0.43 IPC
- Support Timed PEBS (Precise Event-Based Sampling), a recent hardware feature in Intel processors
- Add 'perf ftrace profile' subcommand, using ftrace's function-graph tracer so that users can see the total, average, max execution time as well as the number of invocations easily, for instance:
$ sudo perf ftrace profile -G __x64_sys_perf_event_open -- \ perf stat -e cycles -C1 true 2> /dev/null | head # Total (us) Avg (us) Max (us) Count Function 65.611 65.611 65.611 1 __x64_sys_perf_event_open 30.527 30.527 30.527 1 anon_inode_getfile 30.260 30.260 30.260 1 __anon_inode_getfile 29.700 29.700 29.700 1 alloc_file_pseudo 17.578 17.578 17.578 1 d_alloc_pseudo 17.382 17.382 17.382 1 __d_alloc 16.738 16.738 16.738 1 kmem_cache_alloc_lru 15.686 15.686 15.686 1 perf_event_alloc 14.012 7.006 11.264 2 obj_cgroup_charge
- 'perf sched timehist' improvements, including the addition of priority showing/filtering command line options
- Varios improvements to the 'perf probe', including 'perf test' regression testings
- Introduce the 'perf check', initially to check if some feature is in place, using it in 'perf test'
- Various fixes for 32-bit systems
- Address more leak sanitizer failures
- Fix memory leaks (LBR, disasm lock ops, etc)
- More reference counting fixes (branch_info, etc)
- Constify 'struct perf_tool' parameters to improve code generation and reduce the chances of having its internals changed, which isn't expected
- More constifications in various other places
- Add more build tests, including for JEVENTS
- Add more 'perf test' entries ('perf record LBR', pipe/inject, --setup-filter, 'perf ftrace', 'cgroup sampling', etc)
- Inject build ids for all entries in a call chain in 'perf inject', not just for the main sample
- Improve the BPF based sample filter, allowing root to setup filters in bpffs that then can be used by non-root users
- Allow filtering by cgroups with the BPF based sample filter
- Allow a more compact way for 'perf mem report' using the -T/--type-profile and also provide a --sort option similar to the one in 'perf report', 'perf top', to setup the sort order manually
- Fix --group behavior in 'perf annotate' when leader has no samples, where it was not showing anything even when other events in the group had samples
- Fix spinlock and rwlock accounting in 'perf lock contention'
- Fix libsubcmd fixdep Makefile dependencies
- Improve 'perf ftrace' error message when ftrace isn't available
- Update various Intel JSON vendor event files
- ARM64 CoreSight hardware tracing infrastructure improvements, mostly not visible to users
- Update power10 JSON events

Merge tag 'perf-tools-for-v6.11-2024-07-16' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
Pull perf tools updates from Namhyung Kim: "Build:
- Build each directory as a library so that depedency check for the python extension module can be automatic
- Use pkg-config to check libtraceevent and libtracefs
perf sched:
- Add --task-name and --fuzzy-name options for `perf sched map`
It focuses on selected tasks only by removing unrelated tasks in the output. It matches the task comm with the given string and the --fuzzy-name option allows the partial matching:
$ sudo perf sched record -a sleep 1
$ sudo perf sched map --task-name kworker --fuzzy-name . . . . - *A0 . . 481065.315131 secs A0 => kworker/5:2-i91:438521 . . . . - *- . . 481065.315160 secs *B0 . . . - . . . 481065.316435 secs B0 => kworker/0:0-i91:437860 *- . . . . . . . 481065.316441 secs . . . . . *A0 . . 481065.318703 secs . . . . . *- . . 481065.318717 secs . . *C0 . . . . . 481065.320544 secs C0 => kworker/u16:30-:430186 . . *- . . . . . 481065.320555 secs . . *D0 . . . . . 481065.328524 secs D0 => kworker/2:0-kdm:429654 *B0 .

- Fix -r/--repeat option of perf sched replay
The documentation said -1 will work as infinity but it didn't accept the value. Update the code and document to use 0 instead
- Fix perf sched timehist to account the delay time for preempted tasks
Perf event filtering:
- perf top gained filtering support on regular events using BPF like perf record. Previously it was able to use it for tracepoints only
- The BPF filter now supports filtering by UID/GID. This should be preferred than -u <UID> option as it's racy to scan /proc to check tasks for the user and fails to open an event for the task if it's already gone
$ sudo perf top -e cycles --filter "uid == $(id -u)"
perf report:
- Skip dummy events in the group output by default. The --skip-empty option controls display of empty events without samples. But perf report can force display all events in a group
In this case, auto-added a dummy event (for a system-wide record) ends up in the output. Now it can skip those empty events even in the group display mode
To preserve the old behavior, run this:
$ perf report --group --no-skip-empty
perf stat:
- Choose the most disaggregate option when multiple aggregation options are given. It used to pick the last option in the command line but it can be confusing and not consistent. Now it'll choose the smallest unit
For example, it'd aggregate the result per-core when the user gave both --per-socket and --per-core options at the same time
Internals:
- Fix `perf bench` when some CPUs are offline
- Fix handling of JIT symbol mappings to accept "/tmp/perf-${PID}.map patterns only so that it can not be confused by other /tmp/perf-* files
- Many improvements and fixes for `perf test`
Others:
- Support some new instructions for Intel-PT
- Fix syscall ID mapping in perf trace
- Document AMD IBS PMU usages
- Change `perf lock info` to show map and thread info by default
Vendor JSON events:
- Update Intel events and metrics
- Add i.MX9[35] DDR metrics"

Pull perf tools updates from Arnaldo Carvalho de Melo: "General:
- Integrate the shellcheck utility with the build of perf to allow catching shell problems early in areas such as 'perf test', 'perf trace' scrape scripts, etc
- Add 'uretprobe' variant in the 'perf bench uprobe' tool
- Add script to run instances of 'perf script' in parallel
- Allow parsing tracepoint names that start with digits, such as 9p/9p_client_req, etc. Make sure 'perf test' tests it even on systems where those tracepoints aren't available
- Add Kan Liang to MAINTAINERS as a perf tools reviewer
- Add support for using the 'capstone' disassembler library in various tools, such as 'perf script' and 'perf annotate'. This is an alternative for the use of the 'xed' and 'objdump' disassemblers
Data-type profiling improvements:
- Resolve types for a->b->c by backtracking the assignments until it finds DWARF info for one of those members
- Support for global variables, keeping a cache to speed up lookups
- Handle the 'call' instruction, dealing with effects on registers and handling its return when tracking register data types
- Handle x86's segment based addressing like %gs:0x28, to support things like per CPU variables, the stack canary, etc
- Data-type profiling got big speedups when using capstone for disassembling. The objdump outoput parsing method is left as a fallback when capstone fails or isn't available. There are patches posted for 6.11 that to use a LLVM disassembler
- Support event group display in the TUI when annotating types with --data-type, for instance to show memory load and store events for the data type fields
- Optimize the 'perf annotate' data structures, reducing memory usage
- Add a initial 'perf test' for 'perf annotate', checking that a target symbol appears on the output, specifying objdump via the command line, etc
Vendor Events:
- Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics erroneously in TopdownL1
- Add AMD's Zen 5 core and uncore events and metrics. Those come from the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh Processors" document, with events that capture information on op dispatch, execution and retirement, branch prediction, L1 and L2 cache activity, TLB activity, etc
- Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/ AmpereOneX
Miscellaneous:
- Sync header copies with the kernel sources
- Move some header copies used only for generating translation string tables for ioctl cmds and other syscall integer arguments to a new directory under tools/perf/beauty/, to separate from copies in tools/include/ that are used to build the tools
- Introduce scrape script for several syscall 'flags'/'mask' arguments
- Improve cpumap utilization, fixing up pairing of refcounts, using the right iterators (perf_cpu_map__for_each_cpu), etc
- Give more details about raw event encodings in 'perf list', show tracepoint encoding in the detailed output
- Refactor the DSOs handling code, reducing memory usage
- Document the BPF event modifier and add a 'perf test' for it
- Improve the event parser, better error messages and add further 'perf test's for it
- Add reference count checking to 'struct comm_str' and 'struct mem_info'
- Make ARM64's 'perf test' entries for the Neoverse N1 more robust
- Tweak the ARM64's Coresight 'perf test's
- Improve ARM64's CoreSight ETM version detection and error reporting
