Hi everyone,
I have built up a software virtual prototype system with ARM11MPCORE.
my system is similar with realview_eb_mpcore. but my system is
simpler, which has only a mpcore , uart0, console,timer0_1, and
memorys.
I want to run kernel 2.6.19 on it. I have done some modification, and
now I

OK, then I should update

The platform, spi, and i2c busses use the driver name, which is

Yeah but that does not tell me why it needs the ds1742

Hi Christoph,
A few remarks on these tests:
Why do you printk inside the timing period ? Filling the printk buffers
or outputting on things such as serial console could really hurt your
results.
I hope you run your system with idle=poll and without frequency scaling
at all, because otherwise
I've just acquired this buggy piece of hardware otherwise known as a
NetGear WG111v2. I googled and eventually found an explanation in the
form of source code here:

It seems linux rejects the hardware MAC address because

Cleanup. __group_complete_signal() wakes up -group_exit_task twice. The second
wakeup's state includes TASK_UNINTERRUPTIBLE, which is not very appropriate.
Change the code to pass the correct argument to signal_wake_up() and kill now
unneeded wake_up_process().

Hi Christoph,
Actually, get_cycles() at least on some AMD cpus, do not synchronize the
core, which can skew the results. You might want to use
get_cycles_sync() there.
