I got a bug report today that my recent changes to the Linux kernel

Hi,
The bug was in my last patch.
This is a new one.
I'll very appreciate any comments.

Hello every one,
I try to build a mipsel kernel by myself for qemu-system-mipsel. But
the qemu can not boot it properly. Is there anyone can give me some
suggestion about it.
My method is following,
* Get the kernel of 2.6.18.3 from kernel.org
* Get the config.gz from the mipsel kernel that be

Hi,
I want to instrument all store instructions, and for this I wrote a helper
function (in helper.c) which prints out some information every time a store
is executed. I call this helper function from within every store OPROTO in
ops_mem.h
for example:
void OPPROTO glue(glue(op_stl, MEMSUFFIX),
Hi,
Answering "1. Am I instrumenting all stores if I instrument the OPROTOs in
ops_mem.h? "
Do you consider all updates to memory as stores? e.g. add %ebx, (%eax), will
also write to the memory and
void OPPROTO glue(glue(op_stl, MEMSUFFIX), _T0_A0)(void) or one of its
variant will be called.
If
Hi Atif,
Thanks for the quick reply. Yes, you are right, I want to consider all
updates to memory. Can you tell me if it is sufficient enough to instrument
just those in ops_mem.h? I want to make sure I am not missing any form of
write to the memory (even it is from IO devices, which I think is

Hi Shashi,
I think it is sufficient to add your intercept code in ops_mem.h. I am not
sure about the writes from the I/O though.

Thanks for your suggestion.
Yes, it is a issue about endianness. I already fix it. The default of
kernel for MIPS Qemu is not support the little endian. The
arch/mips/Kconfig must be updated for mipsel.
Thanks for ur help!
Best regard!
