Re: [gem5-users] syscall error while simulating

[Oscar Rosell]

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.

Dear All,

I am getting a syscall unimplemented error while running the

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

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.
