| 2015-06-30 | scripts/gdb: add command to check list consistency | Thiébaud Weksteen | 1 | -0/+1 | |
| Add a gdb script to verify the consistency of lists. Signed-off-by: Thiébaud Weksteen <[email protected]> Signed-off-by: Jan Kiszka <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]> | |||||
| 2015-02-17 | scripts/gdb: add internal helper and convenience function for per-cpu lookup | Jan Kiszka | 1 | -0/+1 | |
| This function allows to obtain a per-cpu variable, either of the current or an explicitly specified CPU. Note: sparc64 version is untested.

| 2015-02-17 | scripts/gdb: add helper and convenience function to look up tasks | Jan Kiszka | 1 | -0/+1 | |
| Add the helper task_by_pid that can look up a task by its PID. Also export it as a convenience function.

| 2015-02-17 | scripts/gdb: add lx-dmesg command | Jan Kiszka | 1 | -0/+1 | |
| This pokes into the log buffer of the debugged kernel, dumping it to the gdb console. Helping in case the target should or can no longer execute dmesg itself.

| 2015-02-17 | scripts/gdb: add internal helper and convenience function to look up a module | Jan Kiszka | 1 | -0/+1 | |
| Add the internal helper get_module_by_name to obtain the module structure corresponding to the given name. Also export this service as a convenience function.

| 2015-02-17 | scripts/gdb: add lx-symbols command | Jan Kiszka | 1 | -0/+1 | |
| This is probably the most useful helper when debugging kernel modules: lx-symbols first reloads vmlinux. Then it searches recursively for *.ko files in the specified paths and the current directory. Finally it walks the kernel's module list, issuing the necessary add-symbol-file command for each loaded module so that gdb knows which module symbol corresponds to which address. It also looks up variable sections (bss, data, rodata) and appends their address to the add-symbole-file command line. This allows to access global module variables just like any other variable.

| 2015-02-17 | scripts/gdb: add container_of helper and convenience function | Jan Kiszka | 1 | -0/+2 | |
| Provide an internal helper with container_of semantics. As type lookups are very slow in gdb-python and we need a type "long" for this, cache the reference to this type object. Then export the helper also as a convenience function form use at the gdb command line.

| 2015-02-17 | scripts/gdb: add infrastructure | Jan Kiszka | 1 | -0/+23 | |
| This provides the basic infrastructure to load kernel-specific python helper scripts when debugging the kernel in gdb. The loading mechanism is based on gdb loading for <objfile>-gdb.py when opening <objfile>. Therefore, this places a corresponding link to the main helper script into the output directory that contains vmlinux. The main scripts will pull in submodules containing Linux specific gdb commands and functions. To avoid polluting the source directory with compiled python modules, we link to them from the object directory. Due to gdb.parse_and_eval and string redirection for gdb.execute, we depend on gdb >= 7.2. This feature is enabled via CONFIG_GDB_SCRIPTS.
