vhost: support PACKED when setting-getting vring_base

2023-06-14T09:13:09+00:00

[ Upstream commit 55d8122f5cd62d5aaa225d7167dcd14a44c850b9 ] Use the right structs for PACKED or split vqs when setting and getting the vring base.

vhost/net: Clear the pending messages when the backend is removed

2023-02-09T10:26:34+00:00

[ Upstream commit 9526f9a2b762af16be94a72aca5d65c677d28f50 ] When the vhost iotlb is used along with a guest virtual iommu and the guest gets rebooted, some MISS messages may have been recorded just before the reboot and spuriously executed by the virtual iommu after the reboot. As vhost does not have any explicit reset user API, VHOST_NET_SET_BACKEND looks a reasonable point where to clear the pending messages, in case the backend is removed. Export vhost_clear_msg() and call it in vhost_net_set_backend() when fd == -1.

vhost: remove work arg from vhost_work_flush

2021-07-03T08:50:54+00:00

vhost_work_flush doesn't do anything with the work arg. This patch drops it and then renames vhost_work_flush to vhost_work_dev_flush to reflect that the function flushes all the works in the dev and not just a specific queue or work item.

vhost: add helper to check if a vq has been setup

2020-11-15T22:30:54+00:00

This adds a helper check if a vq has been setup. The next patches will use this when we move the vhost scsi cmd preallocation from per session to per vq. In the per vq case, we only want to allocate cmds for vqs that have actually been setup and not for all the possible vqs.
