ARM GIC, exceptions & architected timers
3 done - 2 partial - 3 to build
Why it matters
A-profile exception routing, the GIC family, architected timer and PMU interrupts.
What
Build out the 'ARM GIC, exceptions & architected timers' capability area: 8 stories spanning 3 not-yet-built, 0 stubbed, 2 partial and 3 already-implemented (hardening) features.
