[RTnet-developers] IRQ raise in rt_8169 rtnet driver using a NetGear PCI Board...

[jean-francois <jef...@ya...>]

Hello,


I would like to make Ethernet communications between boards with few jitter.
For that, I am using RTNET 0.9.8 and xenomai 2.3 on a linux kernel 
2.6.18.6. My hardware is a powerpc target with a Netgear gigabit PCI board.

Therefore, I use the experimental rt_8169 driver. I succeed in sending 
frames, sending ping requests but the interrupt handler is not called 
when a frame is received by the driver.
I tried to modify the acknowledgment of the interrupt status in 
rtl8169_interrupt  function(I modified it the same way as in the r8169 
linux driver). Whether the acknowledgment is modified or is  as provided 
in rtnet package, the interrupt is never called.

Complementary information :

    * Xernomai is built in the kernel.
    * I do not install tdma.ko.
    * r8169 driver is not installed in the kernel when I use rt_8169.
    * The r8169 linux driver works fine on the target.

What is missing ? Thanks for your help in advance.
