kexec_load on score
load a new kernel for later execution
sys_kexec_load(unsigned long entry, unsigned long nr_segments, struct kexec_segment *segments, unsigned long flags)| number | 104 (0x68) |
|---|---|
| abi | common |
| kconfig | CONFIG_KEXEC |
| entry point | sys_kexec_load |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | kexec_load(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 104, the syscall number |
r4 | unsigned long entry |
r5 | unsigned long nr_segments |
r6 | struct kexec_segment *segments |
r7 | unsigned long flags |
r4 | the return value |
Then run syscall to enter the kernel.
r7 is the error flag and r4 then holds the positive error number.
This architecture was removed from the Linux kernel in Linux 4.17. The newest release with a syscall table here is Linux 4.16. The other removed architectures live on the historical architectures page.
