It's very useful tool! I used it so far on PowerPC targets and now I try to run it on ARM: Cyclone5 ARMv7 CPU. When trying to run LTTng I get: # lttng list --kernel [ 2012.822578] lttng_lib_ring_buffer: section 24 reloc 0 sym '': relocation 42 out of range (0x7f05827c -> 0xc0cd7358) Error: Unable to list kernel events: Kernel tracer not available Error: Command error Do you have any hints how to fix it? I found https://bugs.lttng.org/issues/1173 but enabling CONFIG_ARM_MODULE_PLTS did not help. I use LTTng from Yocto 3.0.2 with custom kernel 4.14.134-rt63-rt: # lttng -V lttng (LTTng Trace Control) 2.10.7 - KeKriek All options recommended from documentation are enabled: root@cyclone5:~# zcat /proc/config.gz | grep -i modules CONFIG_DEFCONFIG_LIST="/lib/modules/$UNAME_RELEASE/.config" CONFIG_MODULES_USE_ELF_REL=y CONFIG_MODULES=y CONFIG_MODULES_TREE_LOOKUP=y # Xtables combined modules # User Modules And Translation Layers root@cyclone5:~# zcat /proc/config.gz | grep -i kallsyms CONFIG_KALLSYMS=y # CONFIG_KALLSYMS_ABSOLUTE_PERCPU is not set CONFIG_KALLSYMS_BASE_RELATIVE=y root@cyclone5:~# zcat /proc/config.gz | grep -i high_res_timers CONFIG_HIGH_RES_TIMERS=y root@cyclone5:~# zcat /proc/config.gz | grep -i tracepoints CONFIG_TRACEPOINTS=y CONFIG_HAVE_SYSCALL_TRACEPOINTS=y Thank you in advance!
