This patch creates kexec_efi_ops to load EFI binary file for kexec_file_load() syscall. The efi_kexec_load() as two parts: - the first part loads the kernel image (vmlinuz.efi or vmlinux.efi) - the second part loads other segments (e.g: initrd, cmdline, etc) Currently, pez (vmlinuz.efi) and pei (vmlinux.efi) format images are supported. The basic usage (vmlinuz.efi or vmlinux.efi): 1) Load second kernel image: # kexec -s -l vmlinuz.efi --initrd=initrd.img --reuse-cmdline 2) Startup second kernel: # kexec -e Signed-off-by: Youling Tang <tangyouling@kylinos.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: maoxiaochuan <maoxiaochuan@loongson.cn>
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.
