config BR2_PACKAGE_KTAP bool "ktap" depends on BR2_LINUX_KERNEL depends on BR2_TOOLCHAIN_HAS_THREADS help ktap is a script-based dynamic tracing tool for Linux It uses a scripting language and lets users trace the Linux kernel dynamically. ktap is designed to give operational insights with interoperability that allows users to tune, troubleshoot and extend kernel and application. It's similar to Linux Systemtap and Solaris Dtrace. ktap doesn't support kernels older than 3.1. Your kernel must have CONFIG_EVENT_TRACING, CONFIG_PERF_EVENTS, and CONFIG_DEBUG_FS enabled to compile. Buildroot automatically enables these in the kernel configuration. http://www.ktap.org comment "ktap needs a Linux kernel to be built" depends on !BR2_LINUX_KERNEL comment "ktap needs a toolchain w/ threads" depends on !BR2_TOOLCHAIN_HAS_THREADS
