Kconfig.debug
menu "Kernel hacking"
source "lib/Kconfig.debug"
config CMDLINE_ON_HOST
bool "Show command line arguments on the host in TT mode"
depends on MODE_TT
default !DEBUG_INFO
help
This controls whether arguments in guest processes should be shown on
the host's ps output.
Enabling this option hinders debugging on some recent GDB versions
(because GDB gets "confused" when we do an execvp()). So probably you
should disable it.
config PT_PROXY
bool "Enable ptrace proxy"
depends on XTERM_CHAN && DEBUG_INFO && MODE_TT
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 DEBUG_STACK_USAGE
bool "Stack utilization instrumentation"
default N
help
Track the maximum kernel stack usage - this will look at each
kernel stack at process exit and log it if it's the deepest
stack seen so far.
This option will slow down process creation and destruction somewhat.
