[Xen-devel] [PATCH v2 00/22] mini-os: support HVMlite mode

[Juergen Gross <jgross@xxxxxxxx>]

This patch series adds HVMlite support for Mini-OS. Setting
CONFIG_PARAVIRT to "n" (default is "y") will build mini-os as a
HVMlite domain on x86. Both 32- and 64-bit builds are supported.

Tested with plain Mini-OS configuration to work in 32- and 64-bit
mode either paravirtualized or as HVM domain (device-model none).

Ballooning should basically work, too, but there is some support for
a sparse memory map missing in HVMlite mode.

Changes in V2:
- some minor changes requested by Samuel Thibault (added comments,
  moved sone code to another position in file, add one print)

Juergen Gross (22):
  mini-os: resync xen headers
  mini-os: make dump_regs() work in early boot
  mini-os: add CONFIG_PARAVIRT
  mini-os: make some memory management related macros usable from
    assembler
  mini-os: add boot code for HVMlite support
  mini-os: setup hypercall page for HVMlite
  mini-os: support hvm_op hypercall
  mini-os: initialize trap handling for HVMlite
  mini-os: support HVMlite traps
  mini-os: make p2m related code depend on CONFIG_PARAVIRT
  mini-os: add static page tables for virtual kernel area for HVMlite
  mini-os: add x86 native page table handling
  mini-os: correct wrong calculation of alloc bitmap size
  mini-os: add map_frame_virt() function
  mini-os: setup console interface parameters
  mini-os: setup xenbus interface parameters
  mini-os: add get_cmdline() function
  mini-os: map shared info page for HVMlite
  mini-os: remove using start_info in architecture independent code
  mini-os: print start of day messages depending on domain type
  mini-os: get physical memory map
  mini-os: support idle for HVMlite
