Add support for hybrid PMUs to support systems such as Intel # Alderlake and its BIG/little core/atom cpus. # # - Introduce 'bperf' to share hardware PMCs with BPF. # # - New --iostat option to collect and present IO stats on Intel # hardware. # # This functionality is based on recently introduced sysfs attributes # for Intel® Xeon® Scalable processor family (code name Skylake-SP) # in commit bb42b3d39781 ("perf/x86/intel/uncore: Expose an Uncore # unit to IIO PMON mapping") # # It is intended to provide four I/O performance metrics in MB per # each PCIe root port: # # - Inbound Read: I/O devices below root port read from the host memory # - Inbound Write: I/O devices below root port write to the host memory # - Outbound Read: CPU reads from I/O devices below root port # - Outbound Write: CPU writes to I/O devices below root port # # - Align CSV output for summary. # # - Clarify --null use cases: Assess raw overhead of 'perf stat' or # measure just wall clock time. # # - Improve readability of shadow stats. # # perf record: # # - Change the COMM when starting tha workload so that --exclude-perf # doesn't seem to be not honoured. # # - Improve 'Workload failed' message printing events + what was # exec'ed. # # - Fix cross-arch support for TIME_CONV. # # perf report: # # - Add option to disable raw event ordering. # # - Dump the contents of PERF_RECORD_TIME_CONV in 'perf report -D'. # # - Improvements to --stat output, that shows information about # PERF_RECORD_ events. # # - Preserve identifier id in OCaml demangler. # # perf annotate: # # - Show full source location with 'l' hotkey in the 'perf annotate' # TUI. # # - Add line number like in TUI and source location at EOL to the 'perf # annotate' --stdio mode. # # - Add --demangle and --demangle-kernel to 'perf annotate'. # # - Allow configuring annotate.demangle{,_kernel} in 'perf config'. # # - Fix sample events lost in stdio mode. # # perf data: # # - Allow converting a perf.data file to JSON. # # libperf: # # - Add support for user space counter access. # # - Update topdown documentation to permit rdpmc calls. # # perf test: # # - Add 'perf test' for 'perf stat' CSV output. # # - Add 'perf test' entries to test the hybrid PMU support. # # - Cleanup 'perf test daemon' if its 'perf test' is interrupted. # # - Handle metric reuse in pmu-events parsing 'perf test' entry. # # - Add test for PE executable support. # # - Add timeout for wait for daemon start in its 'perf test' entries. # # Build: # # - Enable libtraceevent dynamic linking. # # - Improve feature detection output. # # - Fix caching of feature checks caching. # # - First round of updates for tools copies of kernel headers. # # - Enable warnings when compiling BPF programs. # # Vendor specific events: # # - Intel: # - Add missing skylake & icelake model numbers. # # - arm64: # - Add Hisi hip08 L1, L2 and L3 metrics. # - Add Fujitsu A64FX PMU events. # # - PowerPC: # - Initial JSON/events list for power10 platform. # - Remove unsupported power9 metrics. # # - AMD: # - Add Zen3 events. # - Fix broken L2 Cache Hits from L2 HWPF metric. # - Use lowercases for all the eventcodes and umasks. # # Hardware tracing: # # - arm64: # - Update CoreSight ETM metadata format. # - Fix bitmap for CS-ETM option. # - Support PID tracing in config. # - Detect pid in VMID for kernel running at EL2. # # Arch specific updates: # # - MIPS: # - Support MIPS unwinding and dwarf-regs. # - Generate mips syscalls_n64.c syscall table. # # - PowerPC: # - Add support for PERF_SAMPLE_WEIGH_STRUCT on PowerPC. # - Support pipeline stage cycles for powerpc. # # libbeauty: # # - Fix fsconfig generator" # # * tag 'perf-tools-for-v5.13-2021-04-29' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (132 commits) # perf build: Defer printing detected features to the end of all feature checks # tools build: Allow deferring printing the results of feature detection # perf build: Regenerate the FEATURE_DUMP file after extra feature checks # perf session: Dump PERF_RECORD_TIME_CONV event # perf session: Add swap operation for event TIME_CONV # perf jit: Let convert_timestamp() to be backwards-compatible # perf tools: Change fields type in perf_record_time_conv # perf tools: Enable libtraceevent dynamic linking # perf Documentation: Document intel-hybrid support # perf tests: Skip 'perf stat metrics (shadow stat) test' for hybrid # perf tests: Support 'Convert perf time to TSC' test for hybrid # perf tests: Support 'Session topology' test for hybrid # perf tests: Support 'Parse and process metrics' test for hybrid # perf tests: Support 'Track with sched_switch' test for hybrid # perf tests: Skip 'Setup struct perf_event_attr' test for hybrid # perf tests: Add hybrid cases for 'Roundtrip evsel->name' test # perf tests: Add hybrid cases for 'Parse event definition strings' test # perf record: Uniquify hybrid event name # perf stat: Warn group events from different hybrid PMU # perf stat: Filter out unmatched aggregation for hybrid event # ... # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 10a3efd0fee5e881b1866cf45950808575cb0f24 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet32_smp_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0xe8fc40) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xf00000) Image Name: Linux-5.12.0-g10a3efd0fee5 Created: Sun May 2 07:42:16 2021 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6859309 Bytes = 6698.54 KiB = 6.54 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/linus_corenet32_smp_defconfig_powerpc-gcc4.9 # Build took: 0:02:04.938842
