virtio: Implement get_shm_region for PCI transport

2020-09-10T08:05:58+00:00

On PCI the shm regions are found using capability entries;
find a region by searching for the capability.

Revert "virtio_pci: don't duplicate the msix_enable flag in struct pci_dev"

2017-04-10T21:28:41+00:00

This reverts commit 53a020c661741f3b87ad3ac6fa545088aaebac9b.

The cleanup seems to be one of the changes that broke
hybernation for some users. We are still not sure why
but revert helps.

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.
