[PATCH 0/7 v4] MSI-X mask support for assigned device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Change from v3:
1. Re-design the userspace API.
2. Add big-endian support for msix_mmio_read/write()(untested!)

Change from v2:
1. Move all mask handling to kernel, and userspace has to access it using API.
2. Discard userspace mask bit operation API.

  PCI: MSI: Move MSI-X entry definition to pci_regs.h
  PCI: Add mask bit definition for MSI-X table
  KVM: Move struct kvm_io_device to kvm_host.h
  KVM: Add kvm_get_irq_routing_entry() func
  KVM: assigned dev: Clean up assigned_device's flag
