Hi,
These patches have been sitting around as part of a larger series to improve the support of Xen on AArch64. The second part of the work is currently awaiting other re-factoring and build work to go in to make the building of a pure-Xen capable QEMU easier. As that might take some time and these patches are essentially ready I thought I'd best push for merging them.
There are no fundamental changes since the last revision. I've addressed most of the comments although I haven't expanded the use of the global *fdt to other device models. I figured that work could be done as and when models have support for type-1 hypervisors.
I have added some documentation to describe the feature and added an acceptance tests which checks the various versions of Xen can boot. The only minor wrinkle is using a custom compiled Linux kernel due to missing support in the distro kernels. If anyone can suggest a distro which is currently well supported for Xen on AArch64 I can update the test.
The following patches still need review:
- tests/avocado: add boot_xen tests - docs: add some documentation for the guest-loader - docs: move generic-loader documentation into the main manual - hw/core: implement a guest-loader to support static hypervisor guests
