Hi all, This little series implements NOA muxes reprogramming on context switch through the per context batch buffer. NOA muxes resides in slices & subslices, which makes their configuration subject to loss when a slice or subslice is shutdown. The goal of this series is to restore the configuration on context switch. It currently reloads all configurations on context switch but we may be able to be a bit more clever by copying the last RPCS configuration in memory and compare the current configuration before executing all the MI_LRIs using a MI_PREDICATE. Looking forward to comments!
