The intent of the -s/--summary-only option is to just show a summary of the system calls and statistics without any of the individual events. Commit e596663e broke that by showing the interrupted lines: perf trace -i perf.data -s ... 0.741 ( 0.000 ms): sleep/31316 fstat(fd: 4, statbuf: 0x7ffc75ceb830 ) ... 0.744 ( 0.000 ms): sleep/31316 mmap(len: 100244, prot: READ, flags: PRIVATE, fd: 4 ) ... 0.747 ( 0.000 ms): perf/31315 write(fd: 3, buf: 0x7d4bb0, count: 8 ) ... ... Fix by checking for the summary only option. Signed-off-by:

Perf tries to find probe function addresses from map when debuginfo could not be found. To the first added function, the value of ref_reloc_sym was set in maps__set_kallsyms_ref_reloc_sym() and can be obtained from host_machine->kmaps->maps. After that, new maps are added to host_machine->kmaps->maps in dso__load_kcore(), all these new added maps do not have a valid ref_reloc_sym. When adding a second function, get_target_map() may get a map without valid ref_reloc_sym, and raise the error "Relocated base symbol is not found". Fix this by using kernel_get_ref_reloc_sym() to get ref_reloc_sym. This problem can be reproduced as following: $ perf probe --add='sys_write' --add='sys_open' Relocated base symbol is not found! Error: Failed to add events. After this patch: $ perf probe --add='sys_write' --add='sys_open' Added new event: probe:sys_write (on sys_write) You can now use it in all perf tools, such as: perf record -e probe:sys_write -aR sleep 1 Added new event: probe:sys_open (on sys_open) You can now use it in all perf tools, such as: perf record -e probe:sys_open -aR sleep 1 Signed-off-by:He Kuang <hekuang@huawei.com> Tested-by:

Commit f1f13af9 ("perf callchain: Cache eh/debug frame offset for dwarf unwind") introduces a cache for .debug_frame and .eh_frame_hdr. Unfortunately, it makes them share a same cache (dso->frame_offset). Which causes unwind failure on ARM: $ perf test unwind Test dwarf unwind: FAILED! The reason is that, if a dso has '.debug_frame' but doesn't have '.eh_frame_hdr' (like ARM), dso->frame_offset will be filled by offset of '.debug_frame' during the first time calling of find_proc_info() -> read_unwind_spec_debug_frame(), and be regarded to '.eh_frame_hdr' when the second time calling of find_proc_info() -> read_unwind_spec_eh_frame(), since '.eh_frame_hdr' is checked prior to '.debug_frame'. This patch solves the problem by creating two cache fields for '.eh_frame_hdr' and '.debug_frame'. Signed-off-by:

Since some functions (e.g. '_get_comp_words_by_ref()') in perf bash completion script are originally taken from git bash completion script, these functions may be preloaded before perf bash completion script runs. In order to avoid repeating loading the same function twice, some test constraints are used before these function definitions in the perf bash completion script (e.g. 'type _get_comp_words_by_ref &>/dev/null ||'). The problem is that, if these functions in perf bash completion script are changed for some reason, perf will still use the preloaded bash functions rather than the customized functions of its own. As a result, the perf bash completion will behave incorrectly. To get rid of this problem, a flag can be defined to determine the proper situation. And to avoid overwriting the preloaded functions, the names of these functions in perf bash completion script should be renamed to the perf-customized ones. Example: Before this patch: $ type _get_comp_words_by_ref _get_comp_words_by_ref is a function _get_comp_words_by_ref () { local exclude flag i OPTIND=1; local cur cword words=(); local upargs=() upvars=() vcur vcword vprev vwords; while getopts "c:i:n:p:w:" flag "$@"; do case $flag in c) vcur=$OPTARG ;; i) vcword=$OPTARG ;; n) exclude=$OPTARG ;; p) vprev=$OPTARG ;; w) vwords=$OPTARG ;; esac; done; while [[ $# -ge $OPTIND ]]; do case ${!OPTIND} in cur) vcur=cur ;; prev) vprev=prev ;; cword) vcword=cword ;; words) vwords=words ;; *) echo "bash: $FUNCNAME(): \`${!OPTIND}': unknown argument" 1>&2; return 1 ;; esac; let "OPTIND += 1"; done; __get_cword_at_cursor_by_ref "$exclude" words cword cur; [[ -n $vcur ]] && { upvars+=("$vcur"); upargs+=(-v $vcur "$cur") }; [[ -n $vcword ]] && { upvars+=("$vcword"); upargs+=(-v $vcword "$cword") }; [[ -n $vprev && $cword -ge 1 ]] && { upvars+=("$vprev"); upargs+=(-v $vprev "${words[cword - 1]}") }; [[ -n $vwords ]] && { upvars+=("$vwords"); upargs+=(-a${#words[@]} $vwords "${words[@]}") }; (( ${#upvars[@]} )) && local "${upvars[@]}" && _upvars "${upargs[@]}" } As shown above, the _get_comp_words_by_ref is the preloaded function in fact, rather than the function defined in perf-completion.sh. So if we happen to change the function for some reason, the result will behave in a wrong state. After this patch: We can set preload_get_comp_words_by_ref="false" to not use the preloaded function. Instead, it will use the function defined in perf-completion.sh, which is renamed as __perf_get_comp_words_by_ref to avoid overwriting the preloaded function _get_comp_words_by_ref. $ type __perf_get_comp_words_by_ref __perf_get_comp_words_by_ref is a function __perf_get_comp_words_by_ref () { local exclude cur_ words_ cword_; if [ "$1" = "-n" ]; then exclude=$2; shift 2; fi; __my_reassemble_comp_words_by_ref "$exclude"; cur_=${words_[cword_]}; while [ $# -gt 0 ]; do case "$1" in cur) cur=$cur_ ;; prev) prev=${words_[$cword_-1]} ;; words) words=("${words_[@]}") ;; cword) cword=$cword_ ;; esac; shift; done } As shown above, the function __perf_get_comp_words_by_ref is loaded and can work this time. Note that we do not change the original behavior when those functions are not preloaded before perf bash completion script runs. In this case, although the flag is set to "true", the code will still change it to "false" to use the function defined in perf-completion.sh. Signed-off-by: -

The bash completion gives wrong options for 'perf kvm|kmem|mem|lock| sched subsubcommand --<TAB>', where 'kvm|kmem|mem|lock|sched' are all subcommands of perf and 'subsubcommand' is a subcommand of 'kvm|kmem|mem |lock|sched'. In fact, the result incorrectly lists the bash completion of 'perf subcommand' rather than 'perf subcommand subsubcommand'. Example: Before this patch: $ perf kvm record --<TAB> --guest --guestkallsyms --guestmodules --guestmount --guestvmlinux --host --input --output --verbose As shown above, the result is the options of kvm rather than record. After this patch: $ perf kvm record --<TAB> --all-cpus --cgroup --delay --group --no-buildid --output --quiet --stat --uid --branch-any --count --event --intr-regs --no-buildid-cache --period --raw-samples --tid --verbose --branch-filter --cpu --filter --mmap-pages --no-inherit --per-thread --realtime --timestamp --weight --call-graph --data --freq --no-buffering --no-samples --pid --running-time --transaction As shown above, the result is exactly the options of record as we wished.

Commit: c6e5e9fb ("perf tools: Fix building error in x86_64 when dwarf unwind is on") removed the definition of IS_X86_64 but not all places using it, with the consequence that perf-read-vdsox32 would not be built anymore, and the default lib install directory was 'lib' instead of 'lib64'. Also needs to go to v3.19. Signed-off-by:
