Boot Debian in FireSim

[dhand-galois]

Generate a bootable OS binary for FireSim, login, and use all peripherals (block, ethernet, UART).

I am able to boot a gfe Debian image nearly to completion, but it is getting stuck at starting the SSH server:

This is running on a Bluespec P2. I will try again on a Chisel P2 at some point. But I could use help identifying other people that would be able to assist debugging this so I can work on other issues @kiniry

I guess this is a randomness/entropy issue?

[dhand-galois]

Fixed the issues with Debian by following these steps:

• Update riscv-pk to include SiFive UART fixes, set the UART divisor value to 27 if building designs with a 100MHz effective periphery bus frequency.
• Disable ssh.service in the Debian install-systemd.sh script.
• Match GFE_DEBIAN_URL to the one used in testgen, which is a slightly older snapshot
• Enable RISCV_SBI_HVC driver in kernel so UART will go through the HVC driver rather than rely on direct access

The last point will be fixed once we add in the IceNIC/IceBLK/SiFive UART drivers into the GFE linux kernel.

With those changes, Debian boots to login prompt in about 3-4 mins. Going to call this done and open a new issue for bringing up all the peripherals.
