mmap2 on tilepro
map files or devices into memory
sys_mmap2(unsigned long addr, unsigned long len, unsigned long prot, unsigned long flags, unsigned long fd, unsigned long off_4k)| number | 222 (0xde) |
|---|---|
| abi | common |
| entry point | sys_mmap2 |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | mmap2(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r10 | 222, the syscall number |
r0 | unsigned long addr |
r1 | unsigned long len |
r2 | unsigned long prot |
r3 | unsigned long flags |
r4 | unsigned long fd |
r5 | unsigned long off_4k |
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.
