Cover letter [PATCH v7 00/20] xen: add pvh guest support
This patch series adds support for booting Linux as PVH guest.
Similar to i386/xen and x86_64/xen platforms the new i386/xenpvh platform grub is booted as a standalone image directly by Xen.
For booting Linux kernel it is using the standard linux kernel loader. The only modification of the linux loader is to pass the ACPI RSDP address via boot parameters to the kernel, as that table might not be located at the usual physical address just below 1MB.
The related Linux kernel patches have been accepted for 4.20-rc4
Changes in V7:
- fix build failures for various targets (patch 9)
Changes in V6:
- addressed a few comments, see individual patches (only minor changes)
Changes in V5:
- added new patches 7, 17
- removed (old) patch 12 again
- modified boot params interface for passing rsdp address on request by Peter Anvin (patch 2)
- addressed various comments, see individual patches
Changes in V4:
- added new patch 12
- write modified memory map back to Xen
Changes in V3:
- addressed lots of comments, most by Daniel and some by Roger, details are mentioned in the individual patches
Changes in V2:
- extend linux boot protocol version 2.14 to report back the protocol version supported by grub2 (needed as there are grub2 downstream variants in some distros which clobber data after the setup_header)
- split former patch 4 into 10 patches
- fix memmap handling for >4GB of memory
- added new patch from Hans (thanks for that one)
- addressed most of Daniel's comments (see individual patches)
