remap_file_pages on tilepro
create a nonlinear file mapping
sys_remap_file_pages(unsigned long start, unsigned long size, unsigned long prot, unsigned long pgoff, unsigned long flags)| number | 234 (0xea) |
|---|---|
| abi | common |
| entry point | sys_remap_file_pages |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |

Registers
| register | value |
|---|---|
r10 | 234, the syscall number |
r0 | unsigned long start |
r1 | unsigned long size |
r2 | unsigned long prot |
r3 | unsigned long pgoff |
r4 | unsigned long flags |
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.
