• bda9020e2   KVM: remove in_range from io devices ... Browse Code »

  This changes bus accesses to use high-level kvm_io_bus_read/kvm_io_bus_write
  functions. in_range now becomes unused so it is removed from device ops in
  favor of read/write callbacks performing range checks internally.

  This allows aliasing (mostly for in-kernel virtio), as well as better error
  handling by making it possible to pass errors up to userspace.

• 69fa2d786   KVM: document locking for kvm_io_device_ops ... Browse Code »

  slots_lock is taken everywhere when device ops are called.
  Document this as we will use this to rework locking for io.

• d76685c4a   KVM: cleanup io_device code ... Browse Code »

  We modernize the io_device code so that we use container_of() instead of
  dev->private, and move the vtable to a separate ops structure
  (theoretically allows better caching for multiple instances of the same
  ops structure)

  Modify member in_range() of structure kvm_io_device to pass length and the type
  of the I/O (write or read).

  This modification allows to use kvm_io_device with coalesced MMIO.
