kexec_load on metag
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 3.9 or earlier (3.9 is the first release scanned for metag) |
| man page | kexec_load(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
D1Re0 | 104, the syscall number |
D1Ar1 | unsigned long entry |
D0Ar2 | unsigned long nr_segments |
D1Ar3 | struct kexec_segment *segments |
D0Ar4 | unsigned long flags |
D0Re0 | the return value |
Then run SWITCH #0x440001 to enter the kernel.
Values wider than one register are packed into consecutive arguments.
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.
