This patch implements relocation support for ACRN RISC-V to enable position-independent execution. The hypervisor can now be loaded at any physical address and will automatically relocate itself at runtime. Key changes: - Add relocate() function to process R_RISCV_RELATIVE relocations in .rela sections during early boot - Implement arch_get_hv_image_delta() to calculate the load address offset from the configured base address - Add relocation processing in cpu_entry.S before jumping to C code - Update linker script to include .rela sections for relocation data - Define R_RISCV_RELATIVE relocation type and linker symbol definitions Tracked-On: #8825 Signed-off-by: Jian Jun Chen <jian.jun.chen@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>
ACRN Hypervisor ############### The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the "ACRN Device Model". The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on the bare-metal hardware, and is suitable for a variety of IoT and embedded device solutions. The ACRN hypervisor addresses the gap that currently exists between datacenter hypervisors, and hard partitioning hypervisors. The ACRN hypervisor architecture partitions the system into different functional domains, with carefully selected guest OS sharing optimizations for IoT and embedded devices. You can find out more about Project ACRN on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
