# LCPU Idea/Working Model Sheet
|
|
|
|
This is basically the working ideas for the LCPU project.
|
|
|
|
## Core features
|
|
|
|
- CPU SENTs
|
|
- RISC-V rv32ima core
|
|
- Would supporting more than one CPU core type be worthwhile? If so, the project is relatively setup for such workflow...
|
|
- Controllable paramaters (RAM size, ...)
|
|
- Our own frambuffer screen SENT (since wiremod decided to go stupid mode and saw off the gpu)
|
|
|
|
## Code upload/project workflow
|
|
|
|
- Upload a raw binary to execute, generated from any user tooling
|
|
- Yes, this means you can run Linux in GMod. No, I'm not sorry.
|
|
- Or even an ELF? Would require less linker hell?
|
|
|
|
### Integrated simple project workflow
|
|
|
|
### LLVM integration
|
|
|
|
- Use LLVM tools (clang as both assembler driver and C/C++ driver) for compilation.
|
|
- Prebuilt toolchain with compiler-rt can be built. (only needed since compiler-rt isn't usually built with most system clang installations.)
|
|
|
|
- Write assembly/maybe C/C++ code using a tiny project system (data for them would go in server data folder ?)
|
|
|
|
- No conditional compilation
|
|
- All files in a project are built by that project
|
|
|
|
- Diagnostic integration (by either using libclang)
|
|
|
|
- Text editor used to edit project source files
|
|
|
|
- Some example projects?
|
|
- I joke about it, but an RTOS would be really nice and a good stress test of the project system (for usage in "real" projects.)
|
|
|
|
## Moderation/administration tools
|
|
- Admin controlled per-user max RAM size (default 64mb)
|
|
- possibly override for "respectful" users and admins (admins probably wouldn't even count)?
|
|
|
|
- Admin controlled per-user max LCPU entity count (default 8)
|
|
- Admins don't count to limits
|
|
|
|
- Admin controled global (affects all placed LCPUs) scheduler cycle rate.
|
|
- Couldn't be faster than tickrate though or we might block source (and.. well, i dont think i have to explain)
|
|
- I decided not to go with the cpu thread stuff just because its annoying, and would require more state tracking. just ticking in lua using `ENTITY:Think` should be more than good enough (even if theres a risk of hitching source, but I don't think it's that big of a problem...)
|
|
- Project compilations however will definitely end up in a different thread though. Running them in the engine thread would undoubtably cause issues.
|
|
|
|
## Addon interopability
|
|
|
|
- Wiremod interopability
|
|
- Wiremod GPIO peripheral (to interface with wire world)
|
|
- special Console Screen peripheral (interfacing specifically with it)
|
