Hello,
I am executing a full system 64 bit ARM simulation. I use the
linaro-minimal-aarch64.img disk image and the 64 kernel provided by
the gem5 official site. For my testing applications I would like to
get statistics for each different executed pthread. To do that i try
to monitor which pthread is currently being executed in the simulator.
I read in the ARM official site that the TPIDRURO registers contains
the thread local storage address. So i would like to use the value of
this register to distinguish threads in the simulator. When i read the
value of this register it is always set to 0.
I read the register like this :
tc->readMiscReg(MISCREG_TPIDRURO);
I have also tried all the TPIDRURO_X registers implemented by gem5.
None of them contain the Thread local storage. Am I doing something
wrong? Or it is not implemented by gem5? There is always the case that
the kernel does not use this register as a TLS register.
Thank you.
Konstantinos Parasyris.
