When hotplugging CPUs on Tegra186 and Tegra194 errors such as the following are seen ... IRQ63: set affinity failed(-22). IRQ65: set affinity failed(-22). IRQ66: set affinity failed(-22). IRQ67: set affinity failed(-22). Looking at the /proc/interrupts the above are all interrupts associated with GPIOs. The reason why these error messages occur is because there is no 'parent_data' associated with any of the GPIO interrupts and so tegra186_irq_set_affinity() simply returns -EINVAL. To understand why there is no 'parent_data' it is first necessary to understand that in addition to the GPIO interrupts being routed to the interrupt controller (GIC), the interrupts for some GPIOs are also routed to the Tegra Power Management Controller (PMC) to wake up the system from low power states. In order to configure GPIO events as wake events in the PMC, the PMC is configured as IRQ parent domain for the GPIO IRQ domain. Originally the GIC was the IRQ parent domain of the PMC and although this was working, this started causing issues once commit |
