timerfd_gettime on score
timers that notify via file descriptors
sys_timerfd_gettime(int ufd, struct itimerspec *otmr)| number | 87 (0x57) |
|---|---|
| abi | common |
| kconfig | CONFIG_TIMERFD |
| entry point | sys_timerfd_gettime |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | timerfd_gettime(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 87, the syscall number |
r4 | int ufd |
r5 | struct itimerspec *otmr |
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.
