sched_setattr on score
set and get scheduling policy and attributes
sys_sched_setattr(pid_t pid, struct sched_attr *attr, unsigned int flags)| number | 274 (0x112) |
|---|---|
| abi | common |
| entry point | sys_sched_setattr |
| since | Linux 3.14 |
| man page | sched_setattr(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 274, the syscall number |
r4 | pid_t pid |
r5 | struct sched_attr *attr |
r6 | unsigned int 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.
