| |
Hi,
I'm not sure whether there is any demand for kexec_file_load support on arm64, but anyhow I'm working on this and now my early prototype code does work fine.
There is, however, one essential issue: While arm64 kernel requires a device tree blob to be set up correctly at boot time, the current system call API doesn't have this parameter. int kexec_file_load(int kernel_fd, int initrd_fd, unsigned long cmdline_len, const char *cmdline_ptr, unsigned long flags);
Should we invent a new system call, like kexec_file_load2, and, if so, what kind of interface would be desired?
Thanks, -Takahiro AKASHI
