Hi, I try to use run openJPEG binary code on gems/MIPS_SE. There is a fatal error that syscall llseek (#4140) unimplemented as the following. I am not sure the input format is not correct or the simulator doesn't support openJPEG. ----------------------------------------------------------------------------------------------------- Nilay [email protected] to gem5 show details 10:33 AM (3 hours ago)

The message at the end is clear enough. --------------------------------------------------------------------------------- How can I implement such a system call in gem5? Can you give me some suggestion? Thanks. L.J
