OASIS Virtual I/O Device (VIRTIO) TC

I scanned a bunch of issued patents, included please find info on those that I found and that seem relevant to the spec. I also used this opportunity to update and consolidate some existing disclosures that I found e.g. some applications became public or patents issued or new spec sections have been introduced to which the patents are relevant. This is in addition to patent applications disclosures I sent on April 6. Michael S. Tsirkin (20): IPR: add statement regarding Block and SCSI Device IPR: add statement regarding Device Types IPR: add statement regarding IOMMU Device IPR: add statement regarding Entropy Device IPR: add statement regarding Basic Facilities of a Virtio Device IPR: add statement regarding GPU Device IPR: add statement regarding Memory Device IPR: add statement regarding Network Device and Device Types IPR: add statement regarding Network Device and Socket Device IPR: add statement regarding Network Device IPR: add statement regarding Notifications IPR: add statement regarding Traditional Memory Balloon Device and Memory Device IPR: add statement regarding Traditional Memory Balloon Device IPR: add statement regarding Virtio Transport Options and Device Types IPR: add statement regarding Virtio Transport Options and IOMMU Device IPR: add statement regarding Virtio Transport Options and Network Device IPR: add statement regarding Virtio Transport Options and Virtqueues IPR: add statement regarding Virtio Transport Options IPR: add statement regarding Virtqueues and Device Types IPR: add statement regarding Virtqueues IPR.md 543 +++++++++++++++++++++++++++++++++++++++++++++++---------- 1 file changed, 447 insertions(+), 96 deletions(-) -- MST
