Are there any free code available which shows how to configure the ARM interrupt controller (AINTC) on the OMAP-L138 for supporting nested interrupts?
The "Applications Processor System Reference Guide" (SPRUGM7D, April 2010) documents how to perform nesting in chapter 12.3.7. The 11-step procedure is rather complicated though, and I fear there is a bug in it, as preliminary tests have shown unexpected behaviour of the registers.
I'm interested in implementing the second kind of nesting (nesting for individual host).
