| Summary | 0000560: Add support to recognise RISC-V Linux kernel images | ||||
| Description | The RISC-V Linux kernel images (usually called "Image") have a header which is deliberately similar to the AARCH64 Linux kernel. It is described here: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/riscv/include/asm/image.h?h=v6.10.9 and implemented here: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/riscv/kernel/head.S?h=v6.10.9#n22 Attached is a patch to recognise it. | ||||

From 680554c58369d7c70ff79ea5d7b4ca4ea9e417d8 Mon Sep 17 00:00:00 2001 From: Stuart Menefy <stuart.menefy@codasip.com> Date: Wed, 11 Sep 2024 16:59:53 +0100 Subject: [PATCH] Add a pattern to identify RISC-V kernel images. The Linux RISC-V kernel provides a simple header to match against (which is deliberately similar to that used by AARCH64). The current version of this is simply a magic string and a flags field with additional information.
