Linux in simulation #318

Closed hparpinel closed 1 year ago

hparpinel commented 1 year ago

How long should it takes to run Linux in simulation? I am running the ./sim.py and it seems to be stuck at [ 0.665874] io scheduler kyber registered is there something I should do or just let it run?

Dolu1990 commented 1 year ago

some time, there could be ~1 seconds of simulated time between linux consol messages, so, like 15 mn of simulation time

Once I flash the board with Linux how can I check the speed of the CPU? I tried using the command nmeter but it throws the error command not found

Dolu1990 commented 1 year ago

hmm by speed you mean frequency ? or performance ? If you need binaries, you need to enable them in buildroot and regenerate the rootfs

@hparpinel: As pointed by @Dolu1990, with buildroot, you'll have to select/install the packages you are used to on regular distro manually. @Dolu1990 got Debian support working for NaxRiscv (64-bit) and @gsomlo got Fedora support on Rocket (64-bit) so we should be able to provide convenient alternatives soon for developers willing to use regular distros.
