io_getevents on tilepro
read asynchronous I/O events from the completion queue
sys_io_getevents(aio_context_t ctx_id, long min_nr, long nr, struct io_event *events, struct timespec *timeout)| number | 4 (0x4) |
|---|---|
| abi | common |
| kconfig | CONFIG_AIO |
| family | aio see the whole family on tilepro |
| entry point | sys_io_getevents |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |

Registers
| register | value |
|---|---|
r10 | 4, the syscall number |
r0 | aio_context_t ctx_id |
r1 | long min_nr |
r2 | long nr |
r3 | struct io_event *events |
r4 | struct timespec *timeout |
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.
