sched_getaffinity on metag
set and get a thread's CPU affinity mask
sys_sched_getaffinity(pid_t pid, unsigned int len, unsigned long *user_mask_ptr)| number | 123 (0x7b) |
|---|---|
| abi | common |
| entry point | sys_sched_getaffinity |
| since | Linux 3.9 or earlier (3.9 is the first release scanned for metag) |
| man page | sched_getaffinity(2) |

Registers
| register | value |
|---|---|
D1Re0 | 123, the syscall number |
D1Ar1 | pid_t pid |
D0Ar2 | unsigned int len |
D1Ar3 | unsigned long *user_mask_ptr |
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.
