virtio: define virtio_pci_cfg_cap in header.

2015-07-07T11:27:05+00:00

We already have VIRTIO_PCI_CAP_PCI_CFG, let's define the structure that
goes with it.

virtio: define VIRTIO_PCI_CAP_PCI_CFG in header.

2015-02-11T04:33:15+00:00

This provides backdoor access to the device MMIOs, and every device should
have one.  From the virtio 1.0 spec (CS03):

  4.1.4.7.1 Device Requirements: PCI configuration access capability

  The device MUST present at least one VIRTIO_PCI_CAP_PCI_CFG capability.

virtio_pci: macros for PCI layout offsets

2015-01-21T05:58:54+00:00

QEMU wants it, so why not?  Trust, but verify.

virtio_pci: modern driver

2015-01-21T05:58:53+00:00

Lightly tested against qemu.

One thing *not* implemented here is separate mappings
for descriptor/avail/used rings. That's nice to have,
will be done later after we have core support.

This also exposes the PCI layout to userspace, and
adds macros for PCI layout offsets:

virtio-pci: define layout for virtio 1.0

2015-01-21T05:58:51+00:00

Based on patches by Michael S. Tsirkin , but I found it
hard to follow so changed to use structures which are more
self-documenting.

virtio_pci: drop virtio_config dependency

2015-01-21T05:58:44+00:00

virtio_pci does not depend on virtio_config:
let's not include it, users can pull it in as necessary.

virtio_pci: add VIRTIO_PCI_NO_LEGACY

2014-12-14T13:10:31+00:00

Add macro to disable all legacy register defines.
Helpful to make sure legacy macros don't leak
through into modern code.

virtio_pci: better macro exported in uapi

2013-05-20T02:38:09+00:00

Macro VIRTIO_PCI_CONFIG assumes that userspace actually has a structure
with a field named msix_enabled.  Add VIRTIO_PCI_CONFIG_OFF that gets
the msix_enabled by value instead, to make it useful for userspace.  We
still keep VIRTIO_PCI_CONFIG around for now, in case some userspace uses
it.
