Hello,

Does anyone have an idea how to manage the allocation of interrupt vectors
while working with IOCs?
For IP modules it could be solved on the IPAC driver level, but what about
other specific drivers (to rewrite?!.)...
As I understand at the moment interrupt vectors are fixed for each device
driver according to a programmer taste. Could this situation be improved?
At DESY we have integrated an inhouse-made IOC hardware (GPFC) developed
together with IHEP (Russia). Our new device drivers for IP modules are built
around Andrew's IPAC driver.
In case of the GPFC usage ipmIntConnect calls a function administrating
interrupts vectors. Slight changes were necessary in the IPAC driver.
What's about other platforms and more heterogeneous systems? How can an
intelligent management of available vector numbers be achieved?

Let's make our life better! :)

Regards,
Alexei (together with Bernd Schoeneburg).
