Even though a SMMUv3 PMCG implementation may use an MSI as the form of interrupt source, the kernel would still complain that it does not find the wired (GSIV) interrupt in this case: root@(none)$ dmesg | grep arm-smmu-v3-pmcg | grep "not found" [ 59.237219] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.8.auto: IRQ index 0 not found [ 59.322841] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.9.auto: IRQ index 0 not found [ 59.422155] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.10.auto: IRQ index 0 not found [ 59.539014] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.11.auto: IRQ index 0 not found [ 59.640329] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.12.auto: IRQ index 0 not found [ 59.743112] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.13.auto: IRQ index 0 not found [ 59.880577] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.14.auto: IRQ index 0 not found [ 60.017528] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.15.auto: IRQ index 0 not found Use platform_get_irq_optional() to silence the warning. If neither interrupt source is found, then the driver will still warn that IRQ setup errored and the probe will fail.
