tools lib traceevent: Remove libtraceevent

2022-12-14T14:16:12Z

libtraceevent is now out-of-date and it is better to depend on the system version. Remove this code that is no longer depended upon by any builds. Committer notes: Removed the removed tools/lib/traceevent/ from tools/perf/MANIFEST, so that 'make perf-tar-src-pkg' works.

libtraceevent: Add __rel_loc relative location attribute support

2021-12-06T20:37:22Z

Add '__rel_loc' new dynamic data location attribute which encodes the data location from the next to the field itself. This is similar to the '__data_loc' but the location offset is not from the event entry but from the next of the field. This patch adds '__rel_loc' decoding support in the libtraceevent.

KVM: x86/mmu: Rename "nxe" role bit to "efer_nx" for macro shenanigans

2021-06-24T22:00:41Z

Rename "nxe" to "efer_nx" so that future macro magic can use the pattern _ for all CR0, CR4, and EFER bits that included in the role. Using "efer_nx" also makes it clear that the role bit reflects EFER.NX, not the NX bit in the corresponding PTE.

tools lib traceevent: Hide non API functions

2020-10-13T14:47:38Z

There are internal library functions, which are not declared as a static. They are used inside the library from different files. Hide them from the library users, as they are not part of the API. These functions are made hidden and are renamed without the prefix "tep_": tep_free_plugin_paths tep_peek_char tep_buffer_init tep_get_input_buf_ptr tep_get_input_buf tep_read_token tep_free_token tep_free_event tep_free_format_field __tep_parse_format Link: https://lore.kernel.org/linux-trace-devel/e4afdd82deb5e023d53231bb13e08dca78085fb0.camel@decadent.org.uk/ Reported-by: Ben Hutchings Signed-off-by: Tzvetomir Stoyanov (VMware) Reviewed-by: Steven Rostedt (VMware) Cc: linux-trace-devel@vger.kernel.org Link: http://lore.kernel.org/lkml/20200930110733.280534-1-tz.stoyanov@gmail.com Signed-off-by: Arnaldo Carvalho de Melo

Merge tag 'perf-tools-2020-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo: "New features: - Introduce controlling how 'perf stat' and 'perf record' works via a control file descriptor, allowing starting with events configured but disabled until commands are received via the control file descriptor. This allows, for instance for tools such as Intel VTune to make further use of perf as its Linux platform driver. - Improve 'perf record' to to register in a perf.data file header the clockid used to help later correlate things like syslog files and perf events recorded. - Add basic syscall and find_next_bit benchmarks to 'perf bench'. - Allow using computed metrics in calculating other metrics. For instance: { .metric_expr = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit", .metric_name = "DCache_L2_All_Hits", }, { .metric_expr = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss", .metric_name = "DCache_L2_All_Miss", }, { .metric_expr = "dcache_l2_all_hits + dcache_l2_all_miss", .metric_name = "DCache_L2_All", } - Add suport for 'd_ratio', '>' and '<' operators to the expression resolver used in calculating metrics in 'perf stat'. Support for new kernel features: - Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope with things like ftrace, trampolines, i.e. changes in the kernel text that gets in the way of properly decoding Intel PT hardware traces, for instance. Intel PT: - Add various knobs to reduce the volume of Intel PT traces by reducing the level of details such as decoding just some types of packets (e.g., FUP/TIP, PSB+), also filtering by time range. - Add new itrace options (log flags to the 'd' option, error flags to the 'e' one, etc), controlling how Intel PT is transformed into perf events, document some missing options (e.g., how to synthesize callchains). BPF: - Properly report BPF errors when parsing events. - Do not setup side-band events if LIBBPF is not linked, fixing a segfault. Libraries: - Improvements to the libtraceevent plugin mechanism. - Improve libtracevent support for KVM trace events SVM exit reasons. - Add a libtracevent plugins for decoding syscalls/sys_enter_futex and for tlb_flush. - Ensure sample_period is set libpfm4 events in 'perf test'. - Fixup libperf namespacing, to make sure what is in libperf has the perf_ namespace while what is now only in tools/perf/ doesn't use that prefix. Arch specific: - Improve the testing of vendor events and metrics in 'perf test'. - Allow no ARM CoreSight hardware tracer sink to be specified on command line. - Fix arm_spe_x recording when mixed with other perf events. - Add s390 idle functions 'psw_idle' and 'psw_idle_exit' to list of idle symbols. - List kernel supplied event aliases for arm64 in 'perf list'. - Add support for extended register capability in PowerPC 9 and 10. - Added nest IMC power9 metric events. Miscellaneous: - No need to setup sample_regs_intr/sample_regs_user for dummy events. - Update various copies of kernel headers, some causing perf to handle new syscalls, MSRs, etc. - Improve usage of flex and yacc, enabling warnings and addressing the fallout. - Add missing '--output' option to 'perf kmem' so that it can pass it along to 'perf record'. - 'perf probe' fixes related to adding multiple probes on the same address for the same event. - Make 'perf probe' warn if the target function is a GNU indirect function. - Remove //anon mmap events from 'perf inject jit' to fix supporting both using ELF files for generated functions and the perf-PID.map approaches" * tag 'perf-tools-2020-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (144 commits) perf record: Skip side-band event setup if HAVE_LIBBPF_SUPPORT is not set perf tools powerpc: Add support for extended regs in power10 perf tools powerpc: Add support for extended register capability tools headers UAPI: Sync drm/i915_drm.h with the kernel sources tools arch x86: Sync asm/cpufeatures.h with the kernel sources tools arch x86: Sync the msr-index.h copy with the kernel sources tools headers UAPI: update linux/in.h copy tools headers API: Update close_range affected files perf script: Add 'tod' field to display time of day perf script: Change the 'enum perf_output_field' enumerators to be 64 bits perf data: Add support to store time of day in CTF data conversion perf tools: Move clockid_res_ns under clock struct perf header: Store clock references for -k/--clockid option perf tools: Add clockid_name function perf clockid: Move parse_clockid() to new clockid object tools lib traceevent: Handle possible strdup() error in tep_add_plugin_path() API libtraceevent: Fixed description of tep_add_plugin_path() API libtraceevent: Fixed type in PRINT_FMT_STING libtraceevent: Fixed broken indentation in parse_ip4_print_args() libtraceevent: Improve error handling of tep_plugin_add_option() API ...

libtraceevent: Fixed description of tep_add_plugin_path() API

2020-08-06T12:27:33Z

Changed the description of tep_add_plugin_path() API to reflect the logic of the function. The suffix of plugin files is not hardcoded to ".so", it depends on the custom plugin loader callback.
