Hi Sylvain,
the interrupt coalescing sounds like good idea - I'm surprised this
feature is missing in the original ibm_newemac driver. You wrote you
had got this optimisation directly from AMCC. Is it part of any
framework? I'm just wondering how one can obtain it. I tried to find
any suitable pat
Eh! I mean Mb/s NOT Kb/s! Sorry!

with your GPIO pins
with functions like gpio_set_value() - from include/linux/gpio.h.
Documentation of these functions can be seen at

So, this is my solution. Maybe there are better ones, but this

Hi,
I'm writing a linux driver that uses an external interrupt (ppc 405ex). I'm
using GPIO pin 30 (external IRQ 1) connected to UIC1. I'm aware of the
virtual interrupt stuff, so I added a new node to my device tree in order to
get proper virtual IRQ number. This node describes an external event an
