[Minios-devel] [UNIKRAFT PATCHv4 00/43] Add arm64/kvm support for Unikraft

[Wei Chen <Wei.Chen@xxxxxxx>]

This patch series enable Unikraft on arm64/kvm. As we
haven't implemented GIC libraries and full timer support,
this patch series can ONLY work without uksched.
 
What we have done in this patch series:
1. Modified the build scripts and restructured
   the folders to improve the  multi-arch and multi-plat
   support,
2. Added boot code for Arm64 QEMU-KVM platform,
3. Enabled MMU and setup a 1:1 mapping page table for
   physical memory and virtual memory,
4. Added an exception table to handle SYNC, IRQ and other
   exceptions (Just dumping registers in this stage),
5. Supported device tree,
6. A simple PSCI library for CPU suspend, reset and system
   shutdown
7. PL011 UART for console and STDIO
8. A simple virtual timer library for debug timestamp.
