We have the same question with this topic. ( Orin NX R36.2 cannot change IRQ smp affinity ). We need to use PCIe to transmit data at nearly 40Gbps. In R35.1, we were able to achieve this by distributing PCIe interrupts across different CPUs. However, in R36.3, all interrupts are concentrated on CPU0, …
