Hi, This series adds a boottime tracing test framework to selftests/ftrace. This is based on v3 series[1] of the boot-time trace (via bootconfig) testing script.
[1] https://lore.kernel.org/all/178613904128.259829.16130019979800943264.stgit@devnote2/ The new run_boottime_test.sh can run tests not only for boottime trace but also other kernel cmdline tracing options, including persistent ring buffer and its backup. This makes it possible to easily detect regression bugs in the kernel boot trace options. Here is an example of the test output. ----- TAP version 13 1..14 ok 1 01-kprobe ok 2 02-synth ok 3 03-eprobe ok 4 04-fprobe ok 5 05-tprobe ok 6 06-instance ok 7 cmdline-01-ftrace ok 8 cmdline-02-trace-event ok 9 cmdline-03-trace-buf-size ok 10 cmdline-04-trace-options ok 11 cmdline-05-trace-clock ok 12 cmdline-06-trace-instance ok 13 persistent-01-reserve-mem ok 14 persistent-02-backup-instance #
