mprotect on tilepro
set protection on a region of memory
sys_mprotect(unsigned long start, size_t len, unsigned long prot)| number | 226 (0xe2) |
|---|---|
| abi | common |
| entry point | sys_mprotect |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | mprotect(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r10 | 226, the syscall number |
r0 | unsigned long start |
r1 | size_t len |
r2 | unsigned long prot |
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.
