perf_event_open on ia64
set up performance monitoring
sys_perf_event_open(struct perf_event_attr *attr_uptr, pid_t pid, int cpu, int group_fd, unsigned long flags)| number | 1352 (0x548) |
|---|---|
| abi | common |
| kconfig | CONFIG_PERF_EVENTS |
| entry point | sys_perf_event_open |
| since | Linux 5.1 |

Registers
| register | value |
|---|---|
r15 | 1352, the syscall number |
out0 | struct perf_event_attr *attr_uptr |
out1 | pid_t pid |
out2 | int cpu |
out3 | int group_fd |
out4 | unsigned long flags |
r8 | the return value |
Then run break 0x100000 to enter the kernel.
The kernel uses r10 to signal an error.
The pipe call returns file descriptors in r8 and r9.
This architecture was removed from the Linux kernel in Linux 6.7. The newest release with a syscall table here is Linux 6.6. The other removed architectures live on the historical architectures page.
