Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

* virtio memory mapped device
|
|
|
|
See https://ozlabs.org/~rusty/virtio-spec/ for more details.
|
|
|
|
Required properties:
|
|
|
|
- compatible: "virtio,mmio" compatibility string
|
|
- reg: control registers base address and size including configuration space
|
|
- interrupts: interrupt generated by the device
|
|
|
|
Required properties for virtio-iommu:
|
|
|
|
- #iommu-cells: When the node corresponds to a virtio-iommu device, it is
|
|
linked to DMA masters using the "iommus" or "iommu-map"
|
|
properties [1][2]. #iommu-cells specifies the size of the
|
|
"iommus" property. For virtio-iommu #iommu-cells must be
|
|
1, each cell describing a single endpoint ID.
|
|
|
|
Optional properties:
|
|
|
|
- iommus: If the device accesses memory through an IOMMU, it should
|
|
have an "iommus" property [1]. Since virtio-iommu itself
|
|
does not access memory through an IOMMU, the "virtio,mmio"
|
|
node cannot have both an "#iommu-cells" and an "iommus"
|
|
property.
|
|
|
|
Example:
|
|
|
|
virtio_block@3000 {
|
|
compatible = "virtio,mmio";
|
|
reg = <0x3000 0x100>;
|
|
interrupts = <41>;
|
|
|
|
/* Device has endpoint ID 23 */
|
|
iommus = <&viommu 23>
|
|
}
|
|
|
|
viommu: iommu@3100 {
|
|
compatible = "virtio,mmio";
|
|
reg = <0x3100 0x100>;
|
|
interrupts = <42>;
|
|
|
|
#iommu-cells = <1>
|
|
}
