mremap on metag
remap a virtual memory address
sys_mremap(unsigned long addr, unsigned long old_len, unsigned long new_len, unsigned long flags, unsigned long new_addr)| number | 216 (0xd8) |
|---|---|
| abi | common |
| entry point | sys_mremap |
| since | Linux 3.9 or earlier (3.9 is the first release scanned for metag) |
| man page | mremap(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
D1Re0 | 216, the syscall number |
D1Ar1 | unsigned long addr |
D0Ar2 | unsigned long old_len |
D1Ar3 | unsigned long new_len |
D0Ar4 | unsigned long flags |
D1Ar5 | unsigned long new_addr |
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.
