virtio_pci: struct virtio_pci_common_cfg add queue_reset

2022-08-11T08:06:40+00:00

Add queue_reset in virtio_pci_modern_common_cfg. https://github.com/oasis-tcs/virtio-spec/issues/124 https://github.com/oasis-tcs/virtio-spec/issues/139 Signed-off-by: Xuan Zhuo Acked-by: Jason Wang Message-Id: <20220801063902.129329-30-xuanzhuo@linux.alibaba.com> Signed-off-by: Michael S. Tsirkin

virtio_pci: struct virtio_pci_common_cfg add queue_notify_data

2022-08-11T08:06:40+00:00

Add queue_notify_data in struct virtio_pci_common_cfg, which comes from here https://github.com/oasis-tcs/virtio-spec/issues/89 In order not to affect the API, add a dedicated structure struct virtio_pci_modern_common_cfg to virtio_pci_modern.h. Since I want to add queue_reset after queue_notify_data, I submitted this patch first.

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. Tested-by: Mike Galbraith Signed-off-by: Michael S. Tsirkin

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. Signed-off-by: Michael S. Tsirkin

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. Signed-off-by: Rusty Russell Signed-off-by: Michael S. Tsirkin

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: QEMU wants it, so why not? Trust, but verify. Signed-off-by: Rusty Russell Signed-off-by: Michael S. Tsirkin

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. Signed-off-by: Rusty Russell Signed-off-by: Michael S. Tsirkin
