help
This option enables a debugging interface which allows gdb to debug
the kernel without needing to actually attach to kernel threads.
If you want to do kernel debugging, say Y here; otherwise say N.
config GPROF
bool "Enable gprof support"
depends on DEBUG_INFO && MODE_SKAS && !MODE_TT
help
This allows profiling of a User-Mode Linux kernel with the gprof
utility.
See <http://user-mode-linux.sourceforge.net/gprof.html> for more
details.
If you're involved in UML kernel development and want to use gprof,
say Y. If you're unsure, say N.
config GCOV
bool "Enable gcov support"
depends on DEBUG_INFO && MODE_SKAS
help
This option allows developers to retrieve coverage data from a UML
session.
See <http://user-mode-linux.sourceforge.net/gprof.html> for more
details.
If you're involved in UML kernel development and want to use gcov,
say Y. If you're unsure, say N.
config SYSCALL_DEBUG
bool "Enable system call debugging"
default N
depends on DEBUG_INFO
help
This adds some system debugging to UML, including keeping a ring buffer
with recent system calls and some global and per-task statistics.
If unsure, say N
