[ixp1200] SA interrupt

[Arthur Berkovitch]

Hi,
I do exactly as you described with uEng_intConnect, but with VxWorks and
without MicroACE. It works fine!
I looked at the ixasdk2.0
/opt/ixasdk/src/microace/commom/wbench/Inlude/ueng.h and found there the
declaration for uEng_intConnect.
Please let me know about your progress because. I consider moving to
MicroACE and Linux and the SA (or XScale) to ME communication is an issue in
our application.

Subject: [ixp1200] SA interrupt


Hi,
I want to deliver an interrupt from the microengines to the Strong core 
processor of the IXP1200. The core runs Linux.

After reading through the source code of the microengine driver, I figure 
that each time the microengines are initialized, the ue driver registers an 
interrupt handler with the linux kernel for a microengine interrupt. There 
is also a function uEng_intConnect, that can be used to register a handler 
function with this driver. (For example the debug library uses the function 
to register some function).

But this function is not exported to the outside world. If it were, then one

would do something like write a module stacked on the ue module and use the 
uEng_intConnect function to register its own handler function. I cannot 
avoid not using the ue driver because I am using the MicroACE framework.

What can be done so that somehow I can catch a microengine interrupt on the 
core processor?
I don't know if I have been quite clear, but I will appreciate any help. 
Thanks!
