Peter Maydell 7134dbcc63 hw/m68k/mcf_intc: Use qdev input gpios for input IRQs The m68k mcf_intc interrupt controller currently implements its inbound IRQ lines by calling qemu_allocate_irqs() in mcf_intc_init(). This results in leaks like this: Direct leak of 2944 byte(s) in 46 object(s) allocated from: #0 0x5cf95ec15323 in malloc (/home/pm215/qemu/build/san/qemu-system-m68k+0xf9e323) (BuildId: 18d55ef8ea9856e68ee30802078af5050b8b06c5) #1 0x7637c65c5ac9 in g_malloc (/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x62ac9) (BuildId: 116e142b9b52c8a4dfd403e759e71ab8f95d8bb3) #2 0x5cf95f6b2f27 in object_new_with_type /home/pm215/qemu/build/san/../../qom/object.c:767:15 #3 0x5cf95f6aa62e in qemu_allocate_irq /home/pm215/qemu/build/san/../../hw/core/irq.c:91:25 #4 0x5cf95f6aa62e in qemu_extend_irqs /home/pm215/qemu/build/san/../../hw/core/irq.c:79:16 #5 0x5cf95f5f6d99 in mcf5208evb_init /home/pm215/qemu/build/san/../../hw/m68k/mcf5208.c:310:11 This isn't an important leak, as it is memory we allocate once at QEMU startup and that has to stay live for the lifetime of the system. However it does point at a code improvement. Modernise this to have the device itself create inbound GPIOs with qdev_init_gpio_in() that the board can then refer to and wire up individually. As the device is used in only a single board, we can update device and board in a single patch rather than having to try to figure out some way to change the API more piecemeal.
