hi,
I am using kgdb to debug Linux kernel. Both the target and host are
IA32 platform. But I got the following from my gdb console:
Program terminated with signal 0, Signal 0.
The program no longer exists.
In fact, this signal is not defined on my gdb.

Hi,
Thank you very much for the links. I am looking into your thesis right now,
Congratulations! nice work. I really liked the idea of your project,
especially tracking control dependencies along with data dependency in QEMU.
One question I have is the way in which you obtain process information
Minix 3.1.2a installs and runs with no difficulty with CVS qemu.
However when I enable kqemu kqemu-1.3.0pre11, Minix hangs on startup
after printing its memory map.
See http://www.minixtips.com/2006/06/running-minix-under-qemu.html for
easy to follow instructions on the installation.

No. You are using __asm_volatile(mov %al %al) to mark the start of your

scsi.tex patch reduces unnecessary mismatch.
lsi.txt corrects mismatch condition.
When the mismatch happens, register ia saves the instruction address.
However, QEMU call lsi_bad_phase first, update new dsp and
then save it into register ia.
Hi Eduardo,
I think I could not explain my question regarding addl %ebx, (%eax). What
I wanted to ask was that this instruction also accesses the memory and I
also need to intercept it within a transaction. Incase of addl %ebx,
(%eax), Are the functions under /* CPU memory access without any

Hi,
I have a question concerning the system emulation features : what is missing
in the implementation of qemu to get a system emulation of a big endian
ARM1026 target (like qemu-armeb for user emulation) ?
Regards.
Alexis.

In theory most of the bits should be there. However I don't have big-endian
