fc9c112f804abcd984a20a66a909332a147a23e8 - LoongArch: Add ELF binary support for kexec_file

Thu, 02 Oct 2025 16:39:08 +0200

LoongArch: Add ELF binary support for kexec_fileThis patch creates kexec_elf_ops to load ELF binary file forkexec_file_load() syscall.However, for `kbuf->memsz` and `kbuf->buf_min`, special handling isrequired, and the generic `kexec_elf_load()` cannot be used directly.$ readelf -l vmlinux...

This will cause kexec_file to failwhen loading the kernel and need to be converted to a physical address.From the above MemSiz, it can be seen that 0x287a0d8 isn't page aligned.Although kexec_add_buffer() will perform PAGE_SIZE alignment on kbuf->memsz, there is still a stampeding in the loaded kernel space and initrdspace. The initrd resolution failed when starting the second kernel.It can be known from the link script vmlinux.lds.S that, BSS_SECTION(0, SZ_64K, 8) . = ALIGN(PECOFF_SEGMENT_ALIGN);It needs to be aligned according to SZ_64K, so that after alignment, itssize is consistent with _kernel_asize.The basic usage (vmlinux):1) Load second kernel image: # kexec -s -l vmlinux --initrd=initrd.img --reuse-cmdline2) Startup second kernel: # kexec -eSigned-off-by: Youling Tang Signed-off-by: Huacai Chen List of files: /linux/arch/loongarch/kernel/Makefile

Thu, 02 Oct 2025 16:39:07 +0200

LoongArch: Add EFI binary support for kexec_fileThis patch creates kexec_efi_ops to load EFI binary file forkexec_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 aresupported.The basic usage (vmlinuz.efi or vmlinux.efi):1) Load second kernel image: # kexec -s -l vmlinuz.efi --initrd=initrd.img --reuse-cmdline2) Startup second kernel: # kexec -eSigned-off-by: Youling Tang Signed-off-by: Huacai Chen List of files: /linux/arch/loongarch/kernel/Makefile

LoongArch: Add preparatory infrastructure for kexec_fileAdd some preparatory infrastructure:- Add command line processing.- Add support for loading other segments.- Other minor modifications.This initrd will be passed to the second kernel via the command line'initrd=start,size'.The 'kexec_file' command line parameter indicates that the kernel isloaded via kexec_file.Signed-off-by: Youling Tang Signed-off-by: Huacai Chen List of files: /linux/arch/loongarch/kernel/Makefile
