kcmp on cris
compare two processes to determine if they share a kernel resource
sys_kcmp(pid_t pid1, pid_t pid2, int type, unsigned long idx1, unsigned long idx2)| number | 350 (0x15e) |
|---|---|
| abi | common |
| kconfig | CONFIG_KCMP |
| entry point | sys_kcmp |
| since | Linux 3.14 |
| man page | kcmp(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r9 | 350, the syscall number |
r10 | pid_t pid1 |
r11 | pid_t pid2 |
r12 | int type |
r13 | unsigned long idx1 |
mof | unsigned long idx2 |
r10 | the return value |
Then run break 13 to enter the kernel.
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.
