Registers
| register | value |
|---|---|
r10 | 223, the syscall number |
r0 | int fd |
r1 | u32 offset_lo |
r2 | u32 offset_hi |
r3 | u32 len_lo |
r4 | u32 len_hi |
r5 | int advice |
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.
