From: Nick Kossifidis <m...@ics.forth.gr>
This patch adds support for loading the ELF kernel image. It parses
the current/provided device tree to determine the system's memory
layout, and /proc/iomem for the various kernel segments.
This patch was firstly developed by Nick Kossifidis, and two fixes (
1: fail to find free memory area for dtb load when using
initrd image,
lists.infradead.org/pipermail/linux-riscv/2022-August/018398.html;
2: fix memory range size calculation,
kexec/arch/riscv/crashdump-riscv.c:line 85
) are contributed by Yixun Lan, Xianting Tian.
Tested on Qemu's rv64 virt machine and SoC of T-Head RISC-V
Xuantie 910 CPU.
Hi,
thanks for some patch.
Some minor feedback follows.
Separately, I'll post a patch to add RISC-V builds to the github
workflow. If you could include that in V3 I'd be most grateful.

mem_regions_alloc_and_add isn't always available.
f.e. on mips this causes a build failure.

As you know, mem_regions_sort, mem_regions_alloc_and_add are the common
funtions,
The build error of mips is caused by this riscv patch?

Likewise, mem_regions_sort isn't always available.

You can exercise this using:

thanks, I will fix this.
the fix is in my personal gitee
https://gitee.com/xianting-tian/kexec-tools/commits/master
Is this patchset reposting still in your working plan? I don't see the
code in kexe-tools, so ping to ask.
If this is not your work tasks any more, people interested can pick this
patchset and post after polishing.
Now it seems I am interested. FYI my plan is to start working on this
if there is no further reaction from anybody else within a fortnight.
Good, please feel free to do it.
Petr T
