So probably you 14 should disable it. 15 16config PT_PROXY 17 bool "Enable ptrace proxy" 18 depends on XTERM_CHAN && DEBUG_INFO && MODE_TT 19 help 20 This option enables a debugging interface which allows gdb to debug 21 the kernel without needing to actually attach to kernel threads. 22 If you want to do kernel debugging, say Y here; otherwise say N. 23 24config GPROF 25 bool "Enable gprof support" 26 depends on DEBUG_INFO && MODE_SKAS && !MODE_TT 27 help 28 This allows profiling of a User-Mode Linux kernel with the gprof 29 utility. 30 31 See <http://user-mode-linux.sourceforge.net/gprof.html> for more 32 details. 33 34 If you're involved in UML kernel development and want to use gprof, 35 say Y.
