Subject: [OASIS Issue Tracker] (VIRTIO-54) 4.1.2.5: Legacy: PCI Device Layout: fix PCI header fields
[ https://tools.oasis-open.org/issues/browse/VIRTIO-54?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Tsirkin updated VIRTIO-54:
----------------------------------
Proposal:
Fixed in the following patch: https://www.oasis-open.org/apps/org/workgroup/virtio/email/archives/201401/msg00055.html
4.1.2.5: Legacy: PCI Device Layout: fix PCI header fields order
The order of the fields in the legacy PCI header seems to get
messed up in the new spec, with the "Queue Address" moved
behind "Queue Notify". According to the 0.9.5 version of the spec
it should be:
* Device Features 32
* Driver Features 32
* Queue Address 32
* Queue Size 16
* Queue Select 16
* Queue Notify 16
* Device Status 8
* ISR Status 8
