Subject: [PATCH 10/43] virtio: Fail if iommu_platform is requested, but
|
|
unsupported
|
|
|
|
RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
|
|
RH-Bugzilla: 1957194
|
|
|
|
Commit 2943b53f6 (' virtio: force VIRTIO_F_IOMMU_PLATFORM') made sure
|
|
that vhost can't just reject VIRTIO_F_IOMMU_PLATFORM when it was
|
|
requested. However, just adding it back to the negotiated flags isn't
|
|
right either because it promises support to the guest that the device
|
|
actually doesn't support. One example of a vhost-user device that
|
|
doesn't have support for the flag is the vhost-user-blk export of QEMU.
|
|
|
|
Instead of successfully creating a device that doesn't work, just fail
|
|
to plug the device when it doesn't support the feature, but it was
|
|
requested. This results in much clearer error messages.
