User space can register an event with the # kernel describing the format of the event. Then it will receive a # byte in a page mapping that it can check against. A privileged task # can then enable that event like any other event, which will change # the mapped byte to true, telling the user space application to start # writing the event to the tracing buffer. # # - Add new "ftrace_boot_snapshot" kernel command line parameter. When # set, the tracing buffer will be saved in the snapshot buffer at boot # up when the kernel hands things over to user space. This will keep # the traces that happened at boot up available even if user space boot # up has tracing as well. # # - Have TRACE_EVENT_ENUM() also update trace event field type # descriptions. Thus if a static array defines its size with an enum, # the user space trace event parsers can still know how to parse that # array. # # - Add new TRACE_CUSTOM_EVENT() macro. This acts the same as the # TRACE_EVENT() macro, but will attach to an existing tracepoint. This # will make one tracepoint be able to trace different content and not # be stuck at only what the original TRACE_EVENT() macro exports. # # - Fixes to tracing error logging. # # - Better saving of cmdlines to PIDs when tracing (use the wakeup events # for mapping). # # * tag 'trace-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (30 commits) # tracing: Have type enum modifications copy the strings # user_events: Add trace event call as root for low permission cases # tracing/user_events: Use alloc_pages instead of kzalloc() for register pages # tracing: Add snapshot at end of kernel boot up # tracing: Have TRACE_DEFINE_ENUM affect trace event types as well # tracing: Fix strncpy warning in trace_events_synth.c # user_events: Prevent dyn_event delete racing with ioctl add/delete # tracing: Add TRACE_CUSTOM_EVENT() macro # tracing: Move the defines to create TRACE_EVENTS into their own files # tracing: Add sample code for custom trace events # tracing: Allow custom events to be added to the tracefs directory # tracing: Fix last_cmd_set() string management in histogram code # user_events: Fix potential uninitialized pointer while parsing field # tracing: Fix allocation of last_cmd in last_cmd_set() # user_events: Add documentation file # user_events: Add sample code for typical usage # user_events: Add self-test for validator boundaries # user_events: Add self-test for perf_event integration # user_events: Add self-test for dynamic_events integration # user_events: Add self-test for ftrace integration # ... # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 1bc191051dca28fa6d20fd1dc34a1903e7d4fb62 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:5213:warning: override: reassigning to symbol STANDALONE .config:5216:warning: override: reassigning to symbol CPU_BIG_ENDIAN .config:5216:warning: override: CPU_BIG_ENDIAN changes choice state .config:5218:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:5222:warning: override: reassigning to symbol GCC_PLUGINS .config:5225:warning: override: reassigning to symbol UBSAN # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/tools/relocs_check.sh: 60: echo: echo: I/O error Completed OK # rm -rf /kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc11 # Build took: 0:05:28.667342
