patacongo commented on issue #207: SMP for Cortex-A MPcore is unstable URL: https://github.com/apache/incubator-nuttx/issues/207#issuecomment-585253784 I don't see any simple way to implement the first issue you mention, that where g_irqtmp would be invalid in the case of nested interrupts. I see only two solutions and neither are simple: 1. Implement IRQ/FIQ stacks. I am not clear on the design that would use these stacks, but stacking the data should be able to support nesting. 2. Implement ICCMPR interrupt controls and prohibit nesting interrupts altogether.
