epoll_pwait on tilepro
wait for an I/O event on an epoll file descriptor
sys_epoll_pwait(int epfd, struct epoll_event *events, int maxevents, int timeout, const sigset_t *sigmask, size_t sigsetsize)| number | 22 (0x16) |
|---|---|
| abi | common |
| kconfig | CONFIG_EPOLL |
| family | epoll see the whole family on tilepro |
| entry point | sys_epoll_pwait |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |

Registers
| register | value |
|---|---|
r10 | 22, the syscall number |
r0 | int epfd |
r1 | struct epoll_event *events |
r2 | int maxevents |
r3 | int timeout |
r4 | const sigset_t *sigmask |
r5 | size_t sigsetsize |
r0 | the return value |
Then run swint1 to enter the kernel.
The kernel uses r1 to signal an error for ordinary calls.
Fast atomic calls use negative numbers and have different register behavior.
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.
