Hi, I'm playing to do a D based kernel using the OS kit and the other efforts. Of course the first thing to get to work is memory-management. Has someone a totally stripped down GC interface? Or maybe an other GC implementation I can use as a base? -- Robert M. Münch Management & IT Freelancer http://www.robertmuench.de

Just to get things go. It doesn't deserve the name memory-manager yes, but that can be changed later. But the GC is quite complex and uses some other standard D modules, and these use further ones etc. So you start at one point and need to iterate down to the lowest level and implement the pieces step-by-step all way up again.Then again, I could be wrong, too. What kind of kernel are you looking to compile?I'm doing a complete new one. What I'm most interested in is to see how a GCed kernel works and if this propertie can be exported to "apps". IMO a kernel based on D, with DBC, GC etc. really would be a cool thing. And D is the only language I know, that has those features and can go down to the bare metal. -- Robert M.

all you need to run phobos GC, - alloc/release small memory like malloc/free - alloc/release n*pagesize aligned pagesize memory block like mmap(MAP_ANON)/munmap or memalign - get stack top/end additional if threaded - stop/restart all thread - get each thread stack top/end bero
