This is all handled by the "standard" eCos interrupt code. You must
write your HAL to match the interrupt handling semantics of one of the
existing HALs.
Here's a little detail about the interrupt processing:
http://sources.redhat.com/ecos/docs-latest/porting/hal-interrupts.html
To get all the details you'd have to read the code.
Suffice to say that your concerns are all addressed by the "standard"
eCos interrupt handling semantics.
