A mini machine for writing software renderers.
mini maps a raw image to a fixed memory map and runs it. It exposes a framebuffer area (also at a fixed address) for the code to mess with it.
mini runs code in a parallel process under strict seccomp mode — image code cannot do anything else besides drawing, getting hot and crashing.
make. Linux only. Requires SDL 2.0.
Currently only x86 and x86-64 are supported.
./mini image.img
Use --image-size=size to allocate more VA space for the image.
See the sample directory for some code samples.
See arch.h and arch/*.h for the memory map and initial register states.
Crashing images are fair game.
Some support for C code is provided. You need to use the mini.ld linker
script and compile (at least) with -nostdlib and -fno-pie.
