@kirby ok please implement the garbage collector

kirby, 5 months ago

@Ukko I like manual memory management for bare metal scenarios actually

@kirby ok please implement malloc

kirby, 5 months ago

@Ukko give me a couple decades to implement the heap and such

@kirby @Ukko heap is not something thats "implemented" dumbass just brk(2) writing malloc is like on page 100 of k&r its easy

@diazepam @Ukko ahh whatever I have a small brain.

@kirby @Ukko https://tinkeros.github.io/WbGit/Kernel/Mem/MAllocFree.html#l5 btw heres how malloc is implemented in holyc and https://github.com/nrootconauto/Aiwnios/blob/98bd5650f98b1e069df815436b90f36bd7999a29/mem.c#L130 is a ring 3 C port of it

@diazepam @Ukko @kirby i implemented TLSF once. it's not that bad.

not tried to implement immix yet though.

Ukko, 5 months ago

@diazepam @kirby that's not bare metal, all the heavy lifting of page allocation is done by the kernel fol you and you haven't even implemented free with just brk

Ukko, 5 months ago

@diazepam @kirby that being said K&R probably has some linked list malloc-free implementation, I don't remember

@Ukko @kirby you said "ok please implement malloc". you're now moving the goalposts by asking me to map the pages myself. I've played around with TempleOS enough to know how mempagtaskalloc works,thank you

Ukko, 5 months ago

@diazepam @kirby i'm not moving the goalposts, the goalpost was malloc on raw metal

@diazepam @kirby sorry next time i'll copy the messages i'm replying to and mention everything that i think would be inferred from context

@Ukko @kirby depending on what you're doing you may not really need an allocator at all. if you are just programming a microcontroller or something you could just header define a bunch of memory address blocks to specific purposes and leave it at that. imo that only breaks down if you are loading external code that has runtime memory needs

Ukko, 5 months ago

@icst @kirby yea good point there, just having static blocks of memory is the easiest (and fastest (and most likely more bug-free))
