Is RISC-V support in kexec-tools an orphaned project now? > I thought about a simple kexec_file_load only approach previously but I have no time to work on it actually. In theory I think a simple kexec_file_load implementation should only share some common functions eg. arguments parsing, file reading etc. and load the kernel and initrd into memory, pass the fds and cmdline buffer into kernel, that's all, Even no need to have the arch specific file format checking as they should have been done in the related kernel code. But looking at the code it is not easy. Currently the kexec_load and kexec_file_load implementations are not logically separate in the code and the cleanup is hard.
