This commit also converts our own copyright headers to directly use SPDX, but leaves all other copyright header intact, only adding the SPDX ident. As far as possible this commit also merges multiple Data61 copyright statements/headers into one for consistency.

* Intel VT-d (I/O MMU) support
|
|
|
|
Intel VT-d support in seL4 was tested for the following chipsets:
|
|
- Intel Q35 Express
|
|
- Intel 5500
|
|
|
|
On other chipsets with Intel VT-d support, seL4 might:
|
|
- complain and disable IOMMU support
|
|
- hang during bootstrapping
|
|
- have some weird behaviour during runtime
|
|
|
|
In any case, the workaround is to disable VT-d support, either:
|
|
- in the BIOS, or
|
|
- by including "disable_iommu" into the MultiBoot (e.g. GRUB) command line
|
|
as described in the seL4 documentation
