Hello all,
I am new to this mailing list and adeos in general.
I was wondering if there are any test programs out
there to verify the adeos patch is applied properly?
I am applying it to a kernel running on an arm
processor.
Attached a trivial test intercepting the timer IRQ, which at least
demonstrates that the pipeline core works properly.
The definitive test would be to run a complete RTOS like this one over
the patched kernel:
