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'" # # * tag 'perf-tools-for-v6.8-1-2024-01-09' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools: (179 commits) # MAINTAINERS: Add Namhyung as tools/perf/ co-maintainer # perf test: test case 'Setup struct perf_event_attr' fails on s390 on z/vm # perf db-export: Fix missing reference count get in call_path_from_sample() # perf tests: Add perf script test # libsubcmd: Fix memory leak in uniq() # perf TUI: Don't ignore job control # perf vendor events intel: Update sapphirerapids events to v1.17 # perf vendor events intel: Update icelakex events to v1.23 # perf vendor events intel: Update emeraldrapids events to v1.02 # perf vendor events intel: Alderlake/rocketlake metric fixes # perf x86 test: Add hybrid test for conflicting legacy/sysfs event # perf x86 test: Update hybrid expectations # perf vendor events amd: Add Zen 4 memory controller events # perf stat: Fix hard coded LL miss units # perf record: Reduce memory for recording PERF_RECORD_LOST_SAMPLES event # perf env: Avoid recursively taking env->bpf_progs.lock # perf annotate: Add --insn-stat option for debugging # perf annotate: Add --type-stat option for debugging # perf annotate: Support event group display # perf annotate: Add --data-type option # ... # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 9d64bf433c53cab2f48a3fff7a1f2a696bc5229a # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- allnoconfig # < make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig # make -s -j 40 ARCH=mips O=/kisskb/build/linus_allnoconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- Completed OK # rm -rf /kisskb/build/linus_allnoconfig_mipsel-gcc5 # Build took: 0:04:15.297310
