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/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 0df82189bc42037678fa590a77ed0116f428c90d # < make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 allmodconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # < make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:12666:warning: override: reassigning to symbol GCC_PLUGIN_LATENT_ENTROPY .config:12670:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:12672:warning: override: reassigning to symbol UML_NET_SLIP .config:12675:warning: override: reassigning to symbol UML_NET_MCAST .config:12677:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 32 ARCH=um O=/kisskb/build/linus_um-allmodconfig_um-x86_64-gcc12 CROSS_COMPILE=/opt/cross/kisskb/x86-64--glibc--bleeding-edge-2022.08-1/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/drivers/spi/spi-stm32-qspi.c: In function 'stm32_qspi_dirmap_read': /kisskb/src/drivers/spi/spi-stm32-qspi.c:523:27: error: 'op' is used uninitialized [-Werror=uninitialized] 523 \| struct spi_mem_op op; \| ^~ /kisskb/src/drivers/spi/spi-stm32-qspi.c:523:27: note: 'op' declared here 523 \| struct spi_mem_op op; \| ^~ /kisskb/src/drivers/spi/spi-stm32-qspi.c: In function 'stm32_qspi_transfer_one_message': /kisskb/src/drivers/spi/spi-stm32-qspi.c:564:27: error: 'op' is used uninitialized [-Werror=uninitialized] 564 \| struct spi_mem_op op; \| ^~ /kisskb/src/drivers/spi/spi-stm32-qspi.c:564:27: note: 'op' declared here 564 \| struct spi_mem_op op; \| ^~ cc1: all warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:252: drivers/spi/spi-stm32-qspi.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:504: drivers/spi] Error 2 make[3]: * Waiting for unfinished jobs....
