Hi, I am trying to understand how we can find the target CPU for MSI in ARM64. When looking at gic_v3 code I can see following: gic_v3_bind_intr( ) does mapping to next incremental CPU but gic_v3_dist_init( ) does setup boot cpu as the target CPU for MSI interrupts. If I need to find the CPU bound with a particular MSI interrupt, how we can do that? Also is there a way get the the CPU id from the CPU affinity in ARM? Thanks & Regards, Souradeep
