fast user-space locking
sys_futex(u32 *uaddr, int op, u32 val, struct timespec *utime, u32 *uaddr2, u32 val3)| number | 240 (0xf0) |
|---|---|
| abi | common |
| entry point | sys_futex |
| since | Linux 3.3 or earlier (3.3 is the first release scanned for blackfin) |
| man page | futex(2) |

Registers
| register | value |
|---|---|
P0 | 240, the syscall number |
R0 | u32 *uaddr |
R1 | int op |
R2 | u32 val |
R3 | struct timespec *utime |
R4 | u32 *uaddr2 |
R5 | u32 val3 |
R0 | the return value |
Then run excpt 0 to enter the kernel.
