mprotect on metag
set protection on a region of memory
sys_mprotect(unsigned long start, size_t len, unsigned long prot)| number | 226 (0xe2) |
|---|---|
| abi | common |
| entry point | sys_mprotect |
| since | Linux 3.9 or earlier (3.9 is the first release scanned for metag) |
| man page | mprotect(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
D1Re0 | 226, the syscall number |
D1Ar1 | unsigned long start |
D0Ar2 | size_t len |
D1Ar3 | unsigned long prot |
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.
