Interrupt pin is selected and saved into PCI_INTERRUPT_PIN
register during device initialization. Devices should not call
directly qemu_set_irq and specify the INTx pin.
Added pci_* wrappers to replace qemu_set_irq, qemu_irq_raise,
qemu_irq_lower and qemu_irq_pulse, setting the irq
based on PCI_INTERRUPT_PIN.
Added interface to allocate and free single irq.
Added pci_allocate_irq wrapper to be used by devices that
still need PCIDevice infrastructure to assert irqs.
Removed irq field from PCIDevice, not needed anymore.
Special cases of replacements were done in separate patches,
all others in one patch "hw: set interrupts using pci irq wrappers"
Changes from v2:
- Addressed Michael S. Tsirkin's comments:
- Terminate comments by "."
- Add "fixme" comment to pci_irq_pulse
- Addressed Paolo Bonzini's comment:
- fixed implementation of pci_irq_pulse
- Addressed Alex Williamson's comments
- replaced pci_irq_raise/lower with
pci_irq_assert/deassert
- replaced calls to pci_set_irq with
pci_irq_assert/deassert when possible
- Addressed Gerd Hoffmann's comment
- removed irq_pin from UHCIState state
because it is not used anymore
- Fixed a bug in vmxnet3 (deassert was replaced by an assert)
Changes from v1:
- Addressed Michael S. Tsirkin's comments:
- pci_set_irq directly calls pci_irq handler
- removed irq field from PCIDevice
- Added qemu interface to allocate single irq
- Added pci wrappers to allocate and free pci irq
- Added pci irq wrappers for all qemu methods
setting irq and not only qemu_set_irq
- Replace all qemu irq setters with pci
wrappers
