2 tristate "a programable dynamic tracing tool for Linux"
3 depends on PERF_EVENTS && EVENT_TRACING
6 ktap is a new script-based dynamic tracing tool for Linux,
7 it uses a scripting language and lets users trace the
8 Linux kernel dynamically. ktap is designed to give
9 operational insights with interoperability that allow
10 users to tune, troubleshoot and extend kernel and application.
11 It's similar with Linux Systemtap and Solaris Dtrace.
13 ktap have different design principles from Linux mainstream
14 dynamic tracing language in that it's based on bytecode,
15 so it doesn't depend upon GCC, doesn't require compiling
16 kernel module for each script, safe to use in production
17 environment, fulfilling the embedded ecosystem's tracing needs.

23 tristate "FFI support for ktap"
28 This option brings FFI support to ktap. With FFI enabled ktap,
29 users can call into native kernel C function directly in ktap
30 script. Except for a new cdef keyword, this option also adds
31 a ffi module which exports helper functions like ffi.new and
