Hello Thomas, Marc, Mark, (and the funky bunch) The interrupt controller on my SoC supports so-called "software" interrupts, meaning that the HW exposes a 32-bit register in which SW can write some value. If the value written is non-zero, then interrupt 0 is raised. How is such a contraption defined in a device tree? Are there good drivers to read as examples? drivers/irqchip/irq-mips-cpu.c mentions "software interrupts" in the context of "which we don't really use or support."
