This enables much more accurate profiles than when using # the regular 'perf record -e cycles' (the default) when the workload # lasts for very short periods (<10ms). # # - .plt symbol handling improvements, better handling IBT (in the past # MPX) done in the context of decoding Intel PT processor traces, # IFUNC symbols on x86_64, static executables, understanding .plt.got # symbols on x86_64. # # - Add a 'perf test' to test symbol resolution, part of the .plt # improvements series, this tests things like symbol size in contexts # where only the symbol start is available (kallsyms), etc. # # - Better handle auxtrace/Intel PT data when using pipe mode (perf # record sleep 1\|perf report). # # - Fix symbol lookup with kcore with multiple segments match stext, # getting the symbol resolution to just show DSOs as unknown. # # ARM: # # - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace # Macrocell v4). # # - Ensure ARM64 CoreSight timestamps don't go backwards. # # - Document that ARM64 SPE (Statistical Profiling Extension) is used # with 'perf c2c/mem'. # # - Add raw decoding for ARM64 SPEv1.2 previous branch address. # # - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1, # TLB, cache, branch, PE utilization and instruction mix metrics. # # - Update decoder code for OpenCSD version 1.4, on ARM64 systems. # # - Fix command line auto-complete of CPU events on aarch64. # # Build: # # - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked, # as several tests use tracepoints, those should be skipped. # # - More fallout fixes for the removal of tools/lib/traceevent/. # # - Fix build error when linking with libpfm" # # * tag 'perf-tools-for-v6.3-1-2023-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (114 commits) # perf tests stat_all_metrics: Change true workload to sleep workload for system wide check # perf vendor events power10: Add JSON metric events to present CPI stall cycles in powerpc # perf intel-pt: Synthesize cycle events # perf c2c: Add report option to show false sharing in adjacent cachelines # perf record: Fix segfault with --overwrite and --max-size # perf stat: Avoid merging/aggregating metric counts twice # perf tools: Fix perf tool build error in util/pfm.c # perf tools: Fix auto-complete on aarch64 # perf lock contention: Support old rw_semaphore type # perf lock contention: Add -o/--lock-owner option # perf lock contention: Fix to save callstack for the default modified # perf test bpf: Skip test if kernel-debuginfo is not present # perf probe: Update the exit error codes in function try_to_find_probe_trace_event # perf script: Fix missing Retire Latency fields option documentation # perf event x86: Add retire_lat when synthesizing PERF_SAMPLE_WEIGHT_STRUCT # perf test x86: Support the retire_lat (Retire Latency) sample_type check # perf test bpf: Check for libtraceevent support # perf script: Support Retire Latency # perf report: Support Retire Latency # perf lock contention: Support filters for different aggregation # ... # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 0df82189bc42037678fa590a77ed0116f428c90d # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r2el_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- 64r2el_defconfig # < make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r2el_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r2el_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- olddefconfig # make -s -j 160 ARCH=mips O=/kisskb/build/linus_64r2el_defconfig_mips-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/mips-linux/bin/mips-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.19-178.5: Warning (pci_device_reg): /pci@14000000/pci2_root@0,0,0: PCI unit address format error, expected "0,0" Completed OK # rm -rf /kisskb/build/linus_64r2el_defconfig_mips-gcc8 # Build took: 0:00:56.770430
