Linux kernel source tree

Björn Töpel <bjorn@kernel.org> says: From: Björn Töpel <bjorn@rivosinc.com> Hi! For over a year ago, Daniel and I was testing the V2 of Song's series. I also promised to take the V2, that had been sitting on the lists for too long, to rebase it on a new kernel, and re-test it. One year later, here's the V3! ;-) There are no changes from V2 other, than some simple checkpatch cleanups. Song's original cover: | This series makes the kexec_file_load() syscall support to load | Image binary file. At the same time, corresponding support for | kexec-tools had been pushed to my repo[2]. | | Now, we can leverage that kexec-tools and this series to use the | kexec_load() or kexec_file_load() syscall to boot both vmlinux and | Image file, as seen in these combo tests: | | ``` | 1. kexec -l vmlinux | 2. kexec -l Image | 3. kexec -s -l vmlinux | 4. kexec -s -l Image | ``` Notably, kexec-tools has still not made it upstream. I've prepared a branch on my GH [3], that I indend to post ASAP. That branch is a collection of fixes/features, including Song's userland Image loading. The V2 is here [2], and V1 [1]. I've tested the kexec-file/Image on qemu-rv64, with following combinations: * ACPI/UEFI * DT/UEFI * DT both "regular" kexec (-s + -e), and crashkernels (-p). Note that there are two purgatory patches that has to be present (part of -rc1, so all good): commit |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
