perf record: Skip side-band event setup if HAVE_LIBBPF_SUPPORT is not set (2020-08-07 09:27:03 -0300)
----------------------------------------------------------------
perf tools changes for v5.9
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 on 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.
