Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] uml: workaround GDB problems on debugging Apparently, GDB gets confused when we do an execvp() on ourselves. Since it's simply done to allocate further space for command line arguments (which we'll use to allow gathering the startup command line for guest processes through the host), allow the user to disable that to get a debuggable UML binary.

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 SYSCALL_DEBUG
bool "Enable system call debugging"
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
