Hi,
This series is created to improve RISC-V port of kexec-tools,
and is based on the horms/kexec-tools:build-test-riscv-v2 branch.
In my mind the big question is how to move RISC-V support
from that branch, to being merged into main.
IIRC there were some issues that needed to be addressed.
Perhaps they are all addressed by this series, and with
some appropriate squashing we can move forwards with a series
based on main?
Hi, Simon and Nick:
I squashed the first four patches as a "RISC-V: Some fixes for riscv
port" patch and then took the horms/main as the base to collect the 2
patches from horms/build-test-riscv-v2 branch and this series togother.
These are the Github link and all commits for RISC-V.
https://github.com/sugarfillet/kexec-tools/commits/main_rv
5dc133e RISC-V: Support loading Image binary file
b042f6d RISC-V: Separate elf_riscv_find_pbase out
8f344c7 RISC-V: Enable kexec_file_load syscall
7d4b982 RISC-V: Some fixes for riscv port
3205c1c local: RISC-V: distribute purgatory/riscv/Makefile
54f9daf RISC-V: Add support for riscv kexec/kdump on kexec-tools
Since I didn't found the issues/fixes as Nick mentioned with these
commits, I prefer to merge them into horms/main and let more kexec/kdump
users to help improve/fixup RISC-V port.
I would like to listen to your advice.
For your convenience, here is my Github branch for kexec-tools:
https://github.com/sugarfillet/kexec-tools/commits/rv-Image
The first four patches fixes some build or runtime issues:
RISC-V: Use linux,usable-memory-range for crash kernel
RISC-V: Fix the undeclared ‘EM_RISCV’ build failure
RISC-V: Get memory ranges from iomem
RISC-V: Correct the usage of command line option
The last three patches enable the kexec_file_load syscall to load
vmlinux and support loading Image binary file for two syscalls.
RISC-V: Enable kexe_file_load
RISC-V: Separate elf_riscv_find_pbase out
RISC-V: Support loading Image binary file
Note that:
RISC-V Linux kexec_load_file's support for Image file has been sent out but not merged [1].
