kdb: fix compile error without CONFIG_KALLSYMS

2010-08-16T20:58:29+00:00

If CONFIG_KGDB_KDB is set and CONFIG_KALLSYMS is not set the kernel
will fail to build with the error:

kernel/built-in.o: In function `kallsyms_symbol_next':
kernel/debug/kdb/kdb_support.c:237: undefined reference to `kdb_walk_kallsyms'
kernel/built-in.o: In function `kallsyms_symbol_complete':
kernel/debug/kdb/kdb_support.c:193: undefined reference to `kdb_walk_kallsyms'

The kdb_walk_kallsyms needs a #ifdef proper header to match the C
implementation.  This patch also fixes the compiler warnings in
kdb_support.c when compiling without CONFIG_KALLSYMS set.  The
compiler warnings are a result of the kallsyms_lookup() macro not
initializing the two of the pass by reference variables.

vt,console,kdb: automatically set kdb LINES variable

2010-08-05T14:22:30+00:00

The kernel console interface stores the number of lines it is
configured to use. The kdb debugger can greatly benefit by knowing how
many lines there are on the console for the pager functionality
without having the end user compile in the setting or have to
repeatedly change it at run time.

kgdb,kdb: individual register set and and get API

2010-08-05T14:22:20+00:00

The kdb shell specification includes the ability to get and set
architecture specific registers by name.

For the time being individual register get and set will be implemented
on a per architecture basis.  If an architecture defines
DBG_MAX_REG_NUM > 0 then kdb and the gdbstub will use the capability
for individually getting and setting architecture specific registers.

kgdb: Do not access xtime directly

The xtime cleanup missed the kgdb access to xtime. Fix it.

sysrq,kdb: Use __handle_sysrq() for kdb's sysrq function

2010-07-22T00:27:07+00:00

The kdb code should not toggle the sysrq state in case an end user
wants to try and resume the normal kernel execution.

Fix merge regression from external kdb to upstream kdb

2010-07-22T00:27:06+00:00

In the process of merging kdb to the mainline, the kdb lsmod command
stopped printing the base load address of kernel modules.  This is
needed for using kdb in conjunction with external tools such as gdb.

Simply restore the functionality by adding a kdb_printf for the base
load address of the kernel modules.

kdb: break out of kdb_ll() when command is terminated

Without this patch the "ll" linked-list traversal command won't
terminate when you hit q/Q.

module: fix kdb's illicit use of struct module_use.

Linus changed the structure, and luckily this didn't compile any more.

printk,kdb: capture printk() when in kdb shell

2010-05-21T02:04:27+00:00

Certain calls from the kdb shell will call out to printk(), and any of
these calls should get vectored back to the kdb_printf() so that the
kdb pager and processing can be used, as well as to properly channel
I/O to the polled I/O devices.
