getcpu on ia64
determine CPU and NUMA node on which the calling thread is running
sys_getcpu(unsigned *cpup, unsigned *nodep, struct getcpu_cache *unused)| number | 1304 (0x518) |
|---|---|
| abi | common |
| entry point | sys_getcpu |
| since | Linux 5.0 or earlier (5.0 is the first release scanned for ia64) |
| man page | getcpu(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r15 | 1304, the syscall number |
out0 | unsigned *cpup |
out1 | unsigned *nodep |
out2 | struct getcpu_cache *unused |
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.
