Linux kernel modules for the LTTng 2.x kernel tracing
|
|
infrastructure.
|
|
|
|
Make sure your target kernel has the following config
|
|
options enabled:
|
|
|
|
* CONFIG_MODULES: loadable module support (not strictly
|
|
required when built into the kernel)
|
|
* CONFIG_KALLSYMS: this is necessary until the few
|
|
required missing symbols are exported to GPL
|
|
modules from mainline
|
|
* CONFIG_HIGH_RES_TIMERS: needed for LTTng 2.x
|
|
clock source
|
|
* CONFIG_TRACEPOINTS: kernel tracepoint instrumentation
|
|
(enabled as a side-effect of any of the
|
|
perf/ftrace/blktrace instrumentation features)
|
|
* CONFIG_KPROBES (5.7+): use kallsyms for kernel 5.7 and
|
|
newer.
|
|
|
|
The following kernel configuration options will
|
|
affect the features available from LTTng:
|
|
|
|
* CONFIG_HAVE_SYSCALL_TRACEPOINTS: system call tracing
|
|
* CONFIG_PERF_EVENTS: performance counters
|
|
* CONFIG_EVENT_TRACING: needed to allow block layer tracing
|
|
* CONFIG_KPROBES: dynamic probes
|
|
* CONFIG_KRETPROBES: dynamic function entry/return probes
|
|
* CONFIG_KALLSYMS_ALL: state dump of mapping between block
|
|
device number and name
