Bananymous	fb1bab7c30	BuildSystem: add helper to create userspace programs	2023-05-11 18:10:06 +03:00
Bananymous	7eb43990ad	BuildSystem: userspace has cmake target	2023-05-11 16:19:53 +03:00
Bananymous	1cf7ef3de6	Kernel: Remove offset from OpenFileDescriptor ... This is now handled on the libc side. There might be reasons to have it in kernel side, but for simplicity's sake I'm moving it to libc for now :)	2023-05-09 20:31:22 +03:00
Bananymous	812e61ca70	Kernel: Add barebones GeneralAllocator for >4096B	2023-05-08 22:10:49 +03:00
Bananymous	f32d594879	Kernel: We add FixedWidthAllocators on demand ... On SYS_ALLOC we will add a new FixedWidthAllocator if the old ones are already full or we don't have one with proper size. This allows arbitary number of allocations as long as you have enough memory available :) Next I will be writing a general allocator for allocations larger than 4096 bytes which should make SYS_ALLOC syscall complete :)	2023-05-07 23:57:01 +03:00
Bananymous	2fe9af7165	Kernel/LibC: add free function for FixedWidthAllocator ... I have to rework the syscall API and allocators in process. For now this works well enough :)	2023-05-07 01:21:50 +03:00
Bananymous	ff5bcd4416	Kernel: Add basic fixed width allocator for userspace ... We have to move process stacks to the general heap and maybe map kernel to higher half.	2023-05-06 19:58:08 +03:00
Bananymous	7fac2a7526	Userspace: Simple stdio test	2023-04-25 14:50:26 +03:00
Bananymous	b15deb420f	LibC: Write mostly functioning stdio	2023-04-23 14:32:37 +03:00
Bananymous	ec8b9640e2	Kernel: Usespace programs are now ran through ELF files ... only 64 bit elf files are supported for now.	2023-04-22 15:35:32 +03:00
Bananymous	079df39ca8	LibELF: Start implementing elf library	2023-04-18 10:18:15 +03:00
