rt_sigprocmask on score
examine and change blocked signals
sys_rt_sigprocmask(int how, sigset_t *nset, sigset_t *oset, size_t sigsetsize)| number | 135 (0x87) |
|---|---|
| abi | common |
| entry point | sys_rt_sigprocmask |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |

Registers
| register | value |
|---|---|
r27 | 135, the syscall number |
r4 | int how |
r5 | sigset_t *nset |
r6 | sigset_t *oset |
r7 | size_t sigsetsize |
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.
