[Minios-devel] [UNIKRAFT PATCH 0/5] initramfs support

[Robert Hrusecky <roberth@xxxxxxxxxxxxx>]

This patch series introduces functionality required for supporting
initramfs, including a new memory region for the linuxu platform, as
well as CPIO extraction library.

We've added the system calls needed to read the initrd file passed by a
library parameter for the linuxu platform. CPIO extraction code is
contained in a new library and is based on the FreeBSD implementation.
If a CPIO archive is provided, it is extracted and its contents are
mounted as the root filesystem with ramfs.

Robert Hrusecky (5):
  plat/linuxu: Add fstat and open host system calls
  plat/linuxu: Add initrd memory region
  lib/cpio: Create empty CPIO extraction library
  lib/cpio: Add CPIO extraction functionality
  lib/vfscore: Add support to mount initramfs to root
