Nothing prevented IRQ sharing on the ISA bus in principle. Not all boards supported this, neither each and every card nor driver and OS. Still, there existed valid IRQ sharing scenarios, (at least) two of them can also be found in QEMU: >2 PC UARTs and the PREP IDE buses. So remove this artificial restriction from our ISA model.

Like qdev_init(), but terminate program via hw_error() instead of returning an error value. Use it instead of qdev_init() where terminating the program on failure is okay, either because it's during machine construction, or because we know that failure can't happen. Because relying in the latter is somewhat unclean, and the former is not always obvious, it would be nice to go back to qdev_init() in the not-so-obvious cases, only with proper error handling. I'm leaving that for another day, because it involves making sure that error values are properly checked by all callers.

isa-bus owns the isa irqs now, so it can hand them out directly. There is no need for the separate isa_connect_irqs step, drop it. Also hard-code isa interrupts which can't be configured anyway. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Lot of ISA devices work at fixed addresses, so having iobase as bus property doesn't make much sense. Devices which can have different iobases will get a device property. Also simply hard-code stuff which can't be configured anyway. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

由 Jes Sorensen 提交于
Introduce isa_reserve_irq() which marks an irq reserved and returns the appropriate qemu_irq entry from the i8259 table. isa_reserve_irq() is a temporary interface to be used to allocate ISA IRQs for devices which have not yet been converted to qdev, and for special cases which are not suited for qdev conversions, such as the 'ferr'. This patch goes on top of Gerd Hoffmann's which makes isa-bus.c own the ISA irq table.

Changes: (1) make isa-bus maintain isa irqs, complain when allocating already taken irqs. (2) note that (1) works only for isa devices converted to qdev already (floppy and ps2/kbd/mouse right now), so more work is needed to make this really useful. (3) split floppy init into isa and sysbus versions. (4) add sysbus->isa bridge & fix -M isapc breakage.
