[gem5-users] syscall error while simulating

[Puneet Saraf]

Dear All,

I am getting a syscall unimplemented error while running the simulation. For some syscall it gives warning and proceed with the simulation but for some it stopped there itself. Below are the syscall for which my simulation stopped.

fadvise64
timer_create
timer_settime
timer_gettime
timer_getoverrun
timer_delete,
clock_settime
clock_gettime
clock_getres
clock_nanosleep

These error are getting generated from src/arch/x86/linux/process.cc <http://process.cc/>

/* 221 */ SyscallDesc("fadvise64", unimplementedFunc),
/* 222 */ SyscallDesc("timer_create", unimplementedFunc),
/* 223 */ SyscallDesc("timer_settime", unimplementedFunc),
/* 224 */ SyscallDesc("timer_gettime", unimplementedFunc),
/* 225 */ SyscallDesc("timer_getoverrun", unimplementedFunc),
/* 226 */ SyscallDesc("timer_delete", unimplementedFunc),
/* 227 */ SyscallDesc("clock_settime", unimplementedFunc),
/* 228 */ SyscallDesc("clock_gettime", clock_gettimeFunc<X86Linux64>),
/* 229 */ SyscallDesc("clock_getres", clock_getresFunc<X86Linux64>),
/* 230 */ SyscallDesc("clock_nanosleep", unimplementedFunc),


I don’t know what is causing these errors and how to debug and rectify them.
Please help if anybody has any idea about these errors.

Hi,

There's nothing magical about it. Those syscalls are probably just not
implemented. Depending on the Gem5 version you're using they may have
been implemented later (didn't check). Running in Full System mode
instead should work.
