Hello,
I'm trying to get interrupts working for my PCI device on a 460ex and
am having problem. My ISR never triggers.
I'm new to PCI(and ppc) and LDD said that I could read the config reg
INTURRUPT_LINE to get the interrupt assigned to my PCI device. Well,
this always reads zero.

It is a GPL violation that there is no source code available for it.

At the moment when we EOI an interrupt we set the CPPR back to 0xFF
regardless of its previous value. This could lead to problems if we
take an interrupt with a priority of 5, but before EOIing it we get
an IPI which has a priority of 4. The problem is that at the moment
when we EOI the IPI we will

This isn't true.
you may want to rename the ug_ prefix, it took me a while looking
back

What's wrong with ug_ ? (ug = (u)sb(g)ecko)
At first look I thought it was a typo of udbg_early_remap. I prefer

Hi all!
I would like to know if there is someone that tested the MBX driver for the
PowerVR graphic chip in MPC5121 ?
It seems that on kernel 2.6.21 works fine but it fails on 2.6.31 !
I'm using wrlinux as the build environment !
Any opinions are welcome !
Best !
I would like to know whether user can set timeout from user space for the
watchdog.
I am using MPC 8323E processor and linux-2.6.24 kernel.
If user can set, can you tell me how will it be implemented?

Doesn't need to be set to zero AFAIK, since we do a mass initialization
to zero during boot up. Did you notice some type of failure when you
didn't initialize that to zero?
