x86: Remove more unmodified io_apic_ops

2015-04-24T13:36:54+00:00

io_apic_ops.init() is either NULL, if IO-APIC support is disabled at compile time or native_io_apic_init_mappings(). No point to have that as we can achieve the same thing with an empty inline. Signed-off-by: Thomas Gleixner

x86/irq: Remove x86_io_apic_ops.write and x86_io_apic_ops.modify

2015-04-24T13:36:53+00:00

x86_io_apic_ops.write is always set to native_io_apic_write(), and nobody overrides it. So get rid of the indirection by changing native_io_apic_write() as io_apic_write() and removing x86_io_apic_ops.write. Do the same for x86_io_apic_ops.modify and native_io_apic_modify().

Now MSI interrupt has been converted to new hierarchical irqdomain interfaces, so remove legacy MSI related code and interfaces.

Revert "PCI: Add x86_msi.msi_mask_irq() and msix_mask_irq()"

2014-11-11T22:14:30+00:00

The problem fixed by 0e4ccb1505a9 ("PCI: Add x86_msi.msi_mask_irq() and msix_mask_irq()") has been fixed in a simpler way by a previous commit ("PCI/MSI: Add pci_msi_ignore_mask to prevent writes to MSI/MSI-X Mask Bits"). The msi_mask_irq() and msix_mask_irq() x86_msi_ops added by 0e4ccb1505a9 are no longer needed, so revert the commit. default_msi_mask_irq() and default_msix_mask_irq() were added by 0e4ccb1505a9 and are still used by s390, so keep them for now.

PCI: Drop "irq" param from *_restore_msi_irqs()

2013-12-13T15:44:30+00:00

Change x86_msi.restore_msi_irqs(struct pci_dev *dev, int irq) to x86_msi.restore_msi_irqs(struct pci_dev *dev). restore_msi_irqs() restores multiple MSI-X IRQs, so param 'int irq' is unneeded. This makes code more consistent between vm and bare metal. Dom0 MSI-X restore code can also be optimized as XEN only has a hypercall to restore all MSI-X vectors at one time.
