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
