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.

Is RISC-V ready for HPC? Evaluating the 64-core Sophon SG2042 RISC-V CPU
> no absurdely and grotesquely massive and complex compilers anywhere
Absence of evidence is not evidence of absence, and anyway there's not even an absence: https://github.com/riscv-collab/riscv-gnu-toolchain https://llvm.org/docs/RISCVUsage.html
> feature creeps on computer language syntax nowhere to be found
At least one of us is very confused, and in case it's me, how do language details matter to RISC-V?

Help trying to build for riscv64gc-unknown-linux-musl
I then looked at the .cargo/config.toml provided by the guide and saw that it wasn't actually statically compiling the code. After a bit of tinkering and building my own toolchain from here, I ended up with this config.toml file:
- GNU toolchain for RISC-V including GCC
-
Building a toolchain suitable for compiling V extension code
b) collabriscv - essentially gcc 12.2 + binutils master/2.40 as per https://github.com/riscv-collab/riscv-gnu-toolchain
- How do i specify vendor name while building the GNU toolchain?

GCC 13 Adds RISC-V T-Head Vendor Extension Collection
Or would it be better to take what is in https://github.com/riscv-collab/riscv-gnu-toolchain which is gcc 12.2 and start from there?
