[Minios-devel] [UNIKRAFT PATCH 0/5] plat/kvm: x86: Add support for initramdisks

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

Introduces support to locate a loaded initramdisk. For this purpose, we
introduce required platform API definitons. The idea is that an Unikraft
application finds an initramdisk by querying the memory regions. This is
similar to the detection of memory regions that can be used for the heap.
This series inplements initrd support for KVM on x86. 
Additionally, this series is reorganizing KVMs way to store detected
platform configuration during boot: Instead of having individual
platform-global variables (e.g., _libkvmplat_heap_start,
_libkvmplat_stack_top, _libkvmplat_mem_end), we introduce a single
platform-global configuration struct. This is done for readability
reasons.

Simon Kuenzer (5):
  include/essentials: Introduce range test macros
  include/plat: Add flags for initramdisk memory regions
  plat/kvm: Introduce platform configuration struct
  plat/kvm: Add initrd fields to configuration struct
  plat/kvm: x86: Retrieve initrd location from Multiboot
