wait for some event on a file descriptor
sys_ppoll(struct pollfd *ufds, unsigned int nfds, struct __kernel_timespec *tsp, const sigset_t *sigmask, size_t sigsetsize)| number | 73 (0x49) |
|---|---|
| abi | 64 |
| entry point | sys_ppoll |
| since | Linux 5.19 |

Registers
| register | value |
|---|---|
a7 | 73, the syscall number |
a0 | struct pollfd *ufds |
a1 | unsigned int nfds |
a2 | struct __kernel_timespec *tsp |
a3 | const sigset_t *sigmask |
a4 | size_t sigsetsize |
a0 | the return value |
Then run syscall 0 to enter the kernel.
