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/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 1bc191051dca28fa6d20fd1dc34a1903e7d4fb62 # < make -s -j 48 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_64BIT=n # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 48 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- help # make -s -j 48 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- olddefconfig # make -s -j 48 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- :1517:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/arch/sparc/include/asm/cacheflush.h:11:0, from /kisskb/src/include/linux/cacheflush.h:5, from /kisskb/src/drivers/crypto/xilinx/zynqmp-sha.c:6: /kisskb/src/arch/sparc/include/asm/cacheflush_32.h:38:37: error: 'struct page' declared inside parameter list [-Werror] void sparc_flush_page_to_ram(struct page *page); ^ /kisskb/src/arch/sparc/include/asm/cacheflush_32.h:38:37: error: its scope is only this definition or declaration, which is probably not what you want [-Werror] cc1: all warnings being treated as errors make[4]: *** [/kisskb/src/scripts/Makefile.build:288: drivers/crypto/xilinx/zynqmp-sha.o] Error 1 make[3]: *** [/kisskb/src/scripts/Makefile.build:550: drivers/crypto/xilinx] Error 2 make[2]: *** [/kisskb/src/scripts/Makefile.build:550: drivers/crypto] Error 2 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/kisskb/src/Makefile:1831: drivers] Error 2 make: *** [Makefile:219: __sub-make] Error 2 Command 'make -s -j 48 ARCH=sparc O=/kisskb/build/linus_sparc-allmodconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_sparc-allmodconfig_sparc64 # Build took: 0:11:21.104409
