Hi,
sorry to bother anybody again with same subject but I'm debugging some
drivers under Hard Hat Linux for PPC and I can't enable the kgdb to use
it. I tryed to compile the kernel (for K2 750 PPC) after enabling the
kgdb option (using make xconfig) but I have compilation errors:
arch/ppc/kernel/kernel.o: In function `getpacket':
/opt/hardhat/devkit/lsp/k2/linux-2.2.14/arch/ppc/kernel/ppc-stub.c:272:
undefined reference to `getDebugChar'
elocation truncated to fit: R_PPC_REL24 kgdb_interruptible
/opt/hardhat/devkit/lsp/k2/linux-2.2.14/arch/ppc/kernel/ppc-stub.c:685:
undefined reference to `kgdb_interruptible'
/opt/hardhat/devkit/lsp/k2/linux-2.2.14/arch/ppc/kernel/ppc-stub.c:685:
relocation truncated to fit: R_PPC_REL24 kgdb_interruptible
make: *** [vmlinux] Error 1
Did anybody have the same problem?
Thanks
Fabrizio

In order to use kgdb which is in ppc-stubs, you need to have a special
serial port driver which implements getDebugChar, putDebugChar, and
kgdb_interruptible (Although you could probably comment-out this last one).
Based on a grep of 2.4 it doesn't look like there are many non-macintosh options:
[linuxppc_2_4_devel]$ find . -type f | xargs grep kgdb_interruptible
./arch/ppc/8xx_io/uart.c:void kgdb_interruptible(int yes)
./arch/ppc/kernel/ppc-stub.c: kgdb_interruptible(0);
./arch/ppc/kernel/ppc-stub.c: kgdb_interruptible(1);
./drivers/macintosh/macserial.c: kgdb_interruptible(1);
./drivers/macintosh/macserial.c:void kgdb_interruptible(int yes)
./drivers/tc/zs.c:void kgdb_interruptible(int yes)
./include/asm-ppc/kgdb.h:extern void kgdb_interruptible(int); /* control interrupts from serial */
