epoll_ctl on tilepro
control interface for an epoll file descriptor
sys_epoll_ctl(int epfd, int op, int fd, struct epoll_event *event)| number | 21 (0x15) |
|---|---|
| abi | common |
| kconfig | CONFIG_EPOLL |
| family | epoll see the whole family on tilepro |
| entry point | sys_epoll_ctl |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | epoll_ctl(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r10 | 21, the syscall number |
r0 | int epfd |
r1 | int op |
r2 | int fd |
r3 | struct epoll_event *event |
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.
