wait4 on tilepro
wait for process to change state, BSD style
sys_wait4(pid_t pid, int *stat_addr, int options, struct rusage *ru)| number | 260 (0x104) |
|---|---|
| abi | common |
| entry point | sys_wait4 |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | wait4(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r10 | 260, the syscall number |
r0 | pid_t pid |
r1 | int *stat_addr |
r2 | int options |
r3 | struct rusage *ru |
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.
