pread64 on tilepro
read from or write to a file descriptor at a given offset
sys_pread64(unsigned int fd, char *buf, size_t count, loff_t pos)| number | 67 (0x43) |
|---|---|
| abi | common |
| entry point | sys_pread64 |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for tilepro) |
| man page | pread64(2) |

Registers
| register | value |
|---|---|
r10 | 67, the syscall number |
r0 | unsigned int fd |
r1 | char *buf |
r2 | size_t count |
r3 | loff_t pos |
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.
