Hi It has been fixed for full-system simulation (the patch you are referring to is providing visibility of the PMU to the linux kernel), But the syscall in SE mode is still un-implemented. Kind Regards Giacomo > -Original Message- > From: walt_90--- via gem5-users > Sent: 22

Are you talking about Ruby, Garnet and the like? It is perfectly available in the link I gave to you. git clone will provide you with gem5 v.21.1.0.2, the very latest stable release as of today. There is no "special" public version of gem5 I am aware of, anyway. The commands I gave to you are,

[gem5-users] Re: Simulation Frequency is always constant - 1THz

2021-09-23 Thread Gabriel Busnot via gem5-users
Hi, Arthur's answer still stands. As he said, sim_freq is the time resolution of the simulator itself. It defines the points in time where you are 'allowed' to schedule events. By default, you can schedule an event every 1e-12 second of simulated time (1THz). That does not mean all components

Hi Xihui, The error is "died with " I would guess you're out of memory or trying to compile too many files at once. But, it could be many different problems. If it's an issue with dependencies or your host, you can always use our docker images:

Hi Reiko, The KVM CPU requires that the host platform supports KVM. Given that you're using WSL, this means that you need to have nested virtualization enabled and implemented on your WSL kernel.
