apio	8fa72f3cf0	kernel+libc: Implement read()	2023-03-11 18:02:50 +01:00
apio	810c4bc257	kernel+libc: Start interfacing with the VFS from userspace (open & close) ... This commit adds open and close syscalls to the kernel, and adds matching wrappers to libc. No read/write support, so file descriptors are kind of useless for now.	2023-03-11 17:45:20 +01:00
apio	c422d11682	kernel: Start working on a VFS implementation using OOP and SharedPtr	2023-02-27 15:22:24 +01:00
apio	794567327f	kernel, luna: Port non-VFS changes over from pull request #22 ... OwnedPtr, SharedPtr: Add operator bool Option, Result: Make try_move_value() non-const since it modifies the Option kernel: Switch to a stack we control for the main task as soon as we leave early boot Heap: Fix GPF caused when making many small allocations Heap: Avoid accessing a block after it's potentially deleted luna: Skip UBSAN.cpp in CMakeLists as that's not implemented yet luna: Use spinlocks in the heap implementation kernel, luna: Move Spinlock.h to luna Option: Use __builtin_launder to ensure that the compiler doesn't label this as UB SharedPtr: Implement make_shared using adopt_shared SharedPtr: Delete ptr on failure in all adopt_shared* functions	2023-02-25 17:09:03 +01:00
apio	6677c643a5	kernel: Start scanning the PCI bus for devices	2023-01-23 20:07:17 +01:00
apio	7f8a8cdcaf	kernel, libc: Add an usleep() system call and use that to implement usleep() and sleep() in libc	2023-01-22 15:00:20 +01:00
apio	a6974b605e	tools+CMake: Prefix all environment variables with LUNA_	2023-01-21 22:44:16 +01:00
apio	139c0b5eb1	Kernel: Make a UserVM wrapper around Bitmap and use that to allocate user VM ... This lets us allocate more than one page of memory from the user side.	2023-01-13 19:05:20 +01:00
apio	7462b764d8	Kernel: Add __cxa_atexit iomplementation	2023-01-13 18:56:05 +01:00
apio	586ca19b62	Add a VERY BASIC and hacky way of allocating memory from userspace ... Only supports one-page allocations and doesn't have libc wrappers, which means it has to be invoked using syscall().	2023-01-11 23:02:42 +01:00
apio	4287ec6cb0	Bitmap: Introduce a new method 'find' and use it in MM and KernelVM ... This method looks for the first bit with a value, optionally from a starting index, and returns its index. This should be (haven't benchmarked) way faster than the manual way, AKA what MM and KernelVM were doing. This is due to this method using bit and byte manipulation tricks instead of just calling get() until getting the desired result :)	2023-01-09 17:59:52 +01:00
apio	7e377ef712	Implement printf()	2023-01-07 01:49:26 +01:00

apio	f2cc797599	Add a simple ELF loader	2022-12-23 13:09:21 +01:00
apio	ad0f6546d7	Add a global initrd TarStream to make the initial ramdisk accessible everywhere ... It's also mapped into virtual memory instead of directly going into the physical location!!	2022-12-23 11:33:23 +01:00
apio	95b0091622	Split off arch/x86_64/CPU.cpp into various files	2022-12-17 15:45:06 +01:00

apio	6cee208e62	Kernel: Enable -Wsign-conversion ... For real this time, turns out me, being dumb, added it to Luna instead of the kernel.	2022-12-08 15:09:32 +01:00
apio	13f5d09cfd	Add a Scheduler!!	2022-12-07 16:11:59 +00:00

apio	a58b60d0cf	Add a framebuffer text renderer	2022-11-20 17:55:22 +01:00
apio	caf6d1563c	Kernel: Add a heap memory allocator ... This is the first time I've actually dropped liballoc in favor of writing my own implementation. Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job. But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!	2022-11-20 15:15:26 +01:00
