Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

RISC-V simulator
Someone correct me if I'm wrong, but Spike is considered the gold standard for RISV-V simulation, in terms of support for extensions and overall correctness. As I understand it, QEMU is faster and easier to use for day-to-day for general software development.

Hardware/software to run RISC-V ASM?
Spike is an RISC-V instruction set simulator: https://github.com/riscv-software-src/riscv-isa-sim

most underrated cpp project you’ve seen?
I really like the source code for the Spike RISC-V ISA Simulator. It's not very heavily commented, though, so you really need to read the code.

Is there a way to run RISCV sim spike on bare metal?
If you want to run bare metal with no RTOS, it should be possible, but you will need to replace the main startup program (https://github.com/riscv-software-src/riscv-isa-sim/blob/master/spike_main/spike.cc) with some program to set up the hardware and instantiate the simulator, load the OS image etc and then have a decent runtime environment to that supports malloc() etc and redirect IO to serial or flash memory etc. There is a bit of work you would need to do.
- switching between privilege levels

Starting up with RISC-V
I guess you will also use Spike and the Sail model for RISC-V.

Fabrice Bellard's TinyEMU RISC-V Emulator
>"TinyEMU is a system emulator for the RISC-V and x86 architectures.
Its purpose is to be
small and simple
while being complete.
Main features:
o RISC-V system emulator supporting the RV128IMAFDQC base ISA (user level ISA version 2.2, priviledged architecture version 1.10) including:
o 32/64/128 bit integer registers
o 32/64/128 bit floating point instructions (using the SoftFP Library)
o Compressed instructions
o Dynamic XLEN change
o x86 system emulator based on KVM
o VirtIO console, network, block device, input and 9P filesystem
o Graphical display with SDL
o JSON configuration file
o Remote HTTP block device and filesystem
o Small code, easy to modify, few external dependancies
o Javascript version running Linux and Windows 2000."
