get_mempolicy on score
retrieve NUMA memory policy for a thread
sys_get_mempolicy(int *policy, unsigned long *nmask, unsigned long maxnode, unsigned long addr, unsigned long flags)| number | 236 (0xec) |
|---|---|
| abi | common |
| entry point | sys_get_mempolicy |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | get_mempolicy(2) |

Registers
| register | value |
|---|---|
r27 | 236, the syscall number |
r4 | int *policy |
r5 | unsigned long *nmask |
r6 | unsigned long maxnode |
r7 | unsigned long addr |
r8 | 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.
